Tenga Goken: The 5 Great Swords of Japan ~ Part 5

Here is the 5th part of the ongoing series on the Tenga Goken, or the 5 great swords of Japan. Each of these swords has a unique trait that defines its existence as a masterpiece in its own respect. In the case of the Dōjigiri Yasutsuna (童子切安綱), it is not only deemed as the oldest sword, but its beginnings come literally straight out of a fairytale.

Let’s take a look at its details:

  • Status: national treasure
  • Maker: Yasutsuna
  • Blade length: 80 cm
  • Blade curvature: 2.7 cm
  • Blade base width: 2.9 cm
  • Blade tip width: 1.9 cm
  • Length of back of blade: 3.1 cm

There is a great amount of documentation for it over the centuries. Much of these are related to inventory reports, and various accounts by owners and their associates. Others are story-like accounts related to the sword, with some more believable than others. This high documentation is in thanks to the Dōjigiri always in the possession of some high profile groups, along with a few sword enthusiasts. Today, it is in the care of Tokyo National Museum, as it is part of their National Institutes for Cultural Heritage collection.

For this article, we’ll cover more of the relevant recordings, along with some noteworthy ones that play into the theme of the Tenga Goken.

YASUTSUNA

The swordsmith name on the sword’s tang is “Yasutsuna” (安綱). This points to Ōhara Yasutsuna, who was active in Hōki country (present-day western part of Tottori prefecture) during the early Heian period from 806 to 810. This area was known to be rich in pure iron sand, which was essential material for sword crafting. The style of crafting of the Dōjigiri also matches with the Heian period, such as the curvature of the blade. With these strong evidences, it is estimated as the oldest sword out of the Tenga Goken.

Surviving records such as Chōkyō Meizukushi (長享銘尽) point to Aimi county in Hōki country as where he was living. On paper, Yasutsuna is considered as one of Japan’s most recognized swordsmith from far ancient times.

YORIMITSU VS SHUTEN DŌJI

The Dōjigiri’s existence is introduced to the world through a popular tale about Minamoto no Yorimitsu (源頼光) and his bravery. Hailing from the famous Minamoto line, Yorimitsu was, according to surviving records, a real person who lived from 948 from 1021. Curiously, the tales about him and his companions include mythical and superstitious events, which is not uncommon considering the times. There is one particular event where Yorimitsu must play the hero as he was tasked to slay a notorious demon, which is where the Dōjigiri comes into the picture. Here’s a synopsis of how that story goes.


In in they year of 995, the Imperial court tasked Minamoto no Yorimitsu (源頼光) with pacifying a gang of demons lead by a mighty ogre called Shuten Dōji. These criminals have done many heinous acts, including kidnapped women from villages to be eaten later. Yorimitsu set out with 4 of his most trusted retainers dubbed Shitennō (四天王, 4 Heavenly Kings)¹, and traveled the demons’ lair, which was on Mount Daie in Tanba country (present-day area between Kyōto and Hyōgo prefecture).

A woodblock called “Yorimitsu-chōshin Shuten Dōji wo taiji no zu” (頼光朝臣酒呑童子ォ退治之図), featuring Yorimitsu and the Shitennō engaging with the notorious demon gang. This scene includes Shuten Dōji tied with chains while Yorimitsu beheads him, but in a fit the head takes flight and attacks Yorimitsu. By Katsukawa Shuntei.

On their way, they met 3 wise men who gave them items that would aid in defeating the demons. This included a special wine called “shinbenki dokushu” (神便鬼毒酒), which was interpreted as a “divinely conceived poisonous wine for demons”, yet had healing properties for humans². Disguising themselves as mountain ascetics, Yorimitsu and his team were able to deceive the demons in order to gain entry into their lair, and as a thanks to their hospitality, entertained their hosts through dance and wine. After drinking the wine, Shuten Dōji and his gang fell asleep from its neutralizing effects. Seizing the chance, Yorimitsu drew his concealed sword and beheaded Shuten Dōji, while the rest of his team fought off and slew the other demons. Taking the demon leader’s head as a trophy, and freeing the captives, Yorimitsu & his crew returned back to the Imperial court in the Capital³ where they received many honors.

It’s from this episode where the name “Dōjigiri” comes from.


To reiterate, Minamoto no Yorimitsu is recorded as a historical figure who truly did exist. Was the journey he embarked on real? Was Shuten Dōji an actual demon? There are many layers to this story, and the other versions that mirror it, which would need its own article to properly analyze it.

As for Dōjigiri, it gets its name from the lore of being sharp enough to behead a mighty demon. As an heirloom of the Minamoto clan, it makes sense that Yorimitsu would gain possession of it. Yet, how and from whom the Minamoto family acquired this sword is not explained.

POSSESSION OF THE MATSUDAIRA FAMILY

After Yorimitsu, the Dōjigiri is passed into the the hands of several high profile individuals, with the first being the Ashikaga family. There is no clear explanation on how this happened, but estimated time is between late 900s to early 1000s. As an elite military family with status through the Imperial court, the Ashikaga family added the Dōjigiri to their growing collection of valuable treasures, and it would remain there for a few centuries even after their family claimed shogunate in the early-mid 1300s.

In the late 1500s the 15th shogun Ashikaga Yoshiaki gave the sword to Toyotomi Hideyoshi. A superstitious man, Hideyoshi was not pleased to keep a sword with such a history. So he passed it to the Honami family for safe keeping. It’s possible that from this point the Dōjigiri was evaluated, and the name of the swordsmith was discovered. At a later date, Hideyoshi then parted with the sword as he gave it to Tokugawa Ieyasu. After becoming shogun and establishing total control over Japan, Ieyasu gave the Dōjigiri to his son, Hidetada.

On a celebratory day in November of 1611, Hidetada’s daughter Katsuhime was be-wedded to Matsudaira Tadanao, a lord of Kita-no-Sho Domain in Echizen country. Hidetada gave the Dōjigiri to Tadanao as a gift in honor of their family’s unity; while the Tokugawa name was reputable at this point, the same can be said for the Matsudaira mainly due to their long established line, as well as historical connection with the Tokugawa line. The latter saw tremendous benefits, for once the Tokugawa Shogunate was established, this gave opportunities for the Matsudaira families to be positioned as lords over numerous lands. While Tadanao was bringing his land in Echizen country into this unison, Katsuhime’s family was bringing their Takada domain, which was located in Echigo country.

After relinquishing his duties due to old age and retiring into priesthood⁶, Tadanao had his 8-year old son, Mitsunaga, in line to take over the the Kita-no-Sho domain. When he came of age, Mitsunaga would instead became lord of the Takada domain in Echigo country due to political issues. From this point, the Dōjigiri, along with other treasured items of his father, would be left to him.

The Dōjigiri remained as a Matsudaira treasure for several centuries, up until modern time. There were a few cases where it passed into other hands, due to land ownership issues. During those cases, where it was on the land that was up for redistribution, the Dōjigiri ended up on the assets assessment lists drafted up. This made this particular sword well documented, and easily tracked. In 1933, it was appointed as a national treasure by the Ministry of Education (文部省, Monbushō) under the old system. It was also present in the Yūshūkan Sword Exhibition in 1940.

THE PRICE OF BIG SPENDING AND DEBT

Starting around the early 1940s, the Dōjigiri finally leaves the possession of the Matsudaira family, as it would get caught in a power struggle by those willing to pay a hefty price for it. This first went into motion as a Nakajima Kiyoichi had his eyes set on purchasing the Dōjigiri from the Matsudaira family. He made a request to Ishigurō Kuro, a renown sword dealer from Ishikawa prefecture, to see if he could buy it straight from the prestigious owners. At the time, Kuro made attempts, initially purchasing 2 different swords. It wouldn’t be until 1946 when he was finally successful in securing the Dōjigiri, paying ¥80,000⁸ for it. When Kuro reached out to his client to come and buy the sword from him, it seemed as if the deal was gonna go sour, for Kiyoichi didn’t have the money for it.

Reaching out to the Honami family for help, Kiyoichi used their connections to find a business man name Tamari Sannosuke, who was willing to lend money. Sannosuke paid Kuro ¥100,000 for the Dōjigiri. Having such an exclusive sword, Sannosuke relieved the flustered client from being in his debt by offering to take care of the sword. While in his possession, the Dōjigiri was re-evaluated and once again appointed as a national treasure under the new system.

In the mid 1900s, the Dōjigiri was associated to large sums of money, as individuals invested a great amount to get their hands on it. From Photo-AC.

Some drama would unfold a little later, where Sannosuke’s business went bankrupt. He made several attempts to borrow money using the sword, including transferring the sword to a Mr. Murayama for safe keeping and financial support. In 1950, a sword enthusiast named Watanabe Saburō heard about this and contacted Mr. Murayama, as he was willing to pay ¥500,000 as a lending fee, in which Sannosuke agreed. However, several months later into the new year of 1951, Saburō passed away. Sannosuke, who felt that their deal was void due to the death, reached out to the Watanabe family to send back the money and have the Dōjigiri returned to him. As this didn’t go as smoothly as anticipated, both sides would have to try and resolve the matter in court, which spanned for almost a decade.

In 1963, a resolution to end the fight over ownership for the Dōjigiri was made by a member from the Bunkazai Hogoiinkai (文化財保護委員会, National Commission for Protection of Cultural Properties), who would buy the sword completely by paying a hefty price of ¥26,300,000. This amount was split at a specific rate between ¥20,000,000 for Sannosuke, and ¥6,000,000 for the Watanabe family.

With the Dōjigiri in the possession of the Bunkazai Hogoiinkai, it was free from the bidding wars of sword enthusiasts. It was eventually donated to the Tokyo National Museum, where it can be put up on display in exhibits for the public to see.

FUN FACTS

As mentioned earlier, there is an abundant amount of writings on the Dōjigiri, some more interesting than others. While this sword has had its fair share of territorial and ownership disputes, there are a good amount of stories claiming unusual events. Then there are those that are heresay, and can be viewed as baseless rumors or fantasy. Below are a select few that give different perspectives in which how this special sword was interacted with.

1. MORE THAN ONE DEMON-SLAYING SWORD?

As with most old stories from Japan’s ancient times, there are different versions to the famed story of Minamoto no Yorimitsu and his quest to quell Shuten Dōji. The differences vary, from the names used to identify certain individuals, the appearances of certain individuals, to certain details included to give more wilder context (i.e Shuten Dōji’s flying head after decapitation). Fortunately, all these versions share the core parts, which includes Yorimitsu, his loyal followers, Shuten Dōji and his gang at their lair, and the wine that weakened Shuten Dōji enough where Yorimitsu was able to behead him with a sword.

An artwork entitled ” Ichijo Modori bashi no atari nite Higegirimaru no tachi wo motte Ibaraki Dōji no ude wo kiru” (一條戻り橋の邉にて髭切丸の太刀を以茨鬼童子の腕を斬). Watanabe no Tsuna is shown about to cut off the arm of Ibaraki Dōji as they engage in a struggle on the Ichijo Modori bridge. By Utagawa Kuniyoshi.

These differences also affect the representation of Dōjigiri, for while it sounds like this was the key item to Yorimitsu’s victory, there tends to be mentioned of 2 other swords, which are the Onigiri (鬼切) and Higegiri (髭切). Depending on the source, Dōjigiri may be omitted and replaced by one of these 2 other swords, or they appear in the same story but used to fulfill a different task. Here’s an explanation about these other 2 swords:

Onigiri – It’s name can be interpreted as, for the sake of popularity, “Demon-Slayer”. However, its full title is stated as either “Onigirimaru” (鬼切丸) or “Onigiri Yasutsuna” (鬼切安綱). It is argued that the Onigiri is another sword in Yorimitsu’s possession, an heirloom of sorts passed down his family line. In few sources the name “Onigiri” is stated as the sword used to slay Shuten Dōji. Or, that the Dōjigiri’s name was changed to “Onigiri” after the task was done. However, neither are correct. In reality, this sword exists in its own respect, as it is kept as a valuable cultural treasure at the shrine Kitano Tenmangu in Kyōto. Furthermore, the maker’s name on the sword tang is supposedly Yasutsuna, meaning that it and the Dōjigiri are siblings, so to speak.

Despite its existence, there are some oddities surrounding it, leading to questions including the legitimacy as a Yasutsuna-crafted sword. On another note, this is the same sword as the Higegiri. More on this below.

Higegiri – Its name translating as “Whisker-Splitter”, this is another sword that was wielded for the sake of pacifying demons. Origin is that it was a treasured sword of the Minamoto clan, and got its name when it was used to behead a criminal, cutting clean not only through the neck, but the hairs from his beard as well. After their task of ridding Shuten Dōji and his gang, Minamoto no Yorimitsu lent this sword to his retainer Watanabe no Tsuna (渡辺綱) as he went to investigate some troubles in the Capital. As he headed there on horseback, he encountered a woman in distress at a bridge called “Ichijo Modori” (一条通り). Watanabe gave her a hand and lifted her up to sit behind him on his horse, when moments later she transformed into a demon known as Ibaraki Dōji (茨木童子) and grabbed the warrior. A sworn brother of Shuten Dōji, he had escaped from Mt. Daie when Yorimitsu and his retainers terminated his brethrens, and was now attempting to get revenge. Drawing the Higegiri out quickly, Watanabe seized the demon’s right arm, and cut upwards, slicing the arm clean off. After this episode, its name was changed to “Onigiri”.

This sword still exists, as mentioned above, for it is at the shrine Kitano Tenmangu in Kyōto, where it is kept as a cultural treasure. Since the Higegiri is the same sword as the Onigiri, it shares the same discrepancies, as there are questions regarding the legitimacy of its story and other details.

2. OUTRANKING MASAMUNE

Towards the ending of the 1600s, the Matsudaira family who owned Tsuyama Domain in Sakushu (present-day northern part of Okayama Prefecture) gained possession of the Dōjigiri. They also owned 2 other high-quality swords, one was “Inabagō” (稲葉郷) and the other was “Ishida Masamune” (石田正宗).

A pic of the Ishida Masamune on display. From Wikipedia.

All three swords are expertly crafted and high quality. The Ishida Masamune also has an impressive backstory, especially as it is one from the famed Masamune line known for its unrivaled sharpness. Yet, when a member of the Honami family had a chance to evaluate both swords, the Dōjiri was judged to be the better sword.

3. GUARDIAN FOXES

By lore and superstition, there are creatures used as messengers of the gods known as shinshi (神使) in Japan. These creatures existed for the sake of serving or protecting things that are special one way or the other. They are said to take the form of common animals, reptiles, and amphibians, with one of the more popular one being a fox.

There is another tale from Tsuyama Domain’s Matsudaira family, which is said to take place around the same time as the one previously mentioned above. One day, the Dōjigiri was sent out to be delivered for evaluation to Honami Saburobei’s home in Hirokouji, Ueno (an area in present-day Tokyo). While crossing the Sujikai Bridge (筋違橋) on the way to Saburobei’s home, it is said that there were foxes that came out and approached the individual with the Dōjigiri. There was no interaction with the foxes, just their sudden appearance and their momentary company down the same road, until they finally made their way towards a path to Yanaka in Ueno.

The take from this story is that these foxes acted as shinshi, and came to assist in guiding the Dōjigiri safely to its destination.

4. KATSUHIME’S SAYAGAKI

Starting around the late 1500s was a practice called “sayagaki” (鞘書き) through the permission of Toyotomi Hideyoshi, with the particulars including a person writing on the shirasaya of a reputable sword that is generally placed in storage. Swords that will not be used, or to help preserve during the humid summer, have their normal fittings taken off, and are placed in a simple unlacquered wooden sheath known as a shirasaya (白鞘), with an equally simple wooden sword handle. A peculiar practice, it allowed details about the sword to be written on the sheath without the need to draw it out.

An example of sayagaki.

In 1623, the Dōjigiri was stored in a shirasaya while it, along with other properties, was under the ownership of Katsuhime until her son was old enough to inherit them. There was sayagaki on the sheath of the Dōjigiri, and it is thought to have been done by Katsuhime herself, based on the writing style at that time.

This is what was written on the shirasaya of the Dojigiri:


JAPANESE:
表 童子切貳尺六寸五分
裏 鎺元ニテ壹寸横手下ニテ六分半重厚サ貳分

ENGLISH:
Front: Dōjigiri, measuring at 2 shaku 6 sun 5 bu
Back: There is a hole measuring 1 sun at the base of the habaki (鎺, metal collar between the sword and the hand guard), 6 1/2 bu line below the yokote (横手, line on the side of the blade between the tip and the cutting edge), with a thickness of 2 bu


There is a description about these lines and how it is judged to be written by a woman, most likely Katsuhime. However, I am not sure who made this judgement.

5. EAST VS WEST

Within Asian culture there is a rather unique labeling of 2 things that are considered equal in strength and quality. Influenced by the ying-yang theory, these 2 things stand side-by-side and represent balance, even if both objects are rivals or mortal enemies.

Amongst sword enthusiasts, there is a statement that declares both the Dōjigiri and another sword called Ōkanehira (大包平) as equals. The line goes as follows:

“日本刀の東西の両横綱”

This translates to “Japan’s best 2 swords from the East and the West”. The East-West comparison is due to the fact that the Dōjigiri was crafted in Hōki country, which is located in western Japan, while the Ōkanehira was made in Bizen country, located in eastern Japan. Looking at the history of the Ōkanehira, it was made during the late Heian period by an individual known as “Kanehira”, who belonged to the swordsmith group called “Ko-Bizen” (古備前). Like the Dōjigiri, the style of the Ōkanehira is stated as exquisite, as it has unique qualities matching the era it was crafted.

The reasoning behind this assertion points to how old both swords are estimated to be, for they have survived centuries up until present day.

6. CUTTING TEST

Sometime around the ending of the 1600s during the Edo period, the sharpness of the Dōjigiri was put to the test. While the sword was still in the possession of the Matsudaira family of Tsuyama Domain, there was a request to test just how strong it was. This event was set up as a “tameshigiri”, or “test cutting”, where an attempt would be made to cut through as many human bodies with the Dōjigiri in one swing. Not an unusual practice, tameshigiri was a means to evaluate the cutting power of swords of all types, and rate them by the number of targets they are able to cleave through…with the targets being close to or being exactly that of the human body. In the case of the Dōjigiri, the dead bodies of criminals were used.

A reputable swordsman within the area by the name of Machida Chōdayū (町田長太夫), who was a renown expert at tameshigiri, was given the task of testing this legendary sword’s sharpness. At its finest moment, Chōdayuu was able to completely slice through not only 6 dead bodies in one motion while wielding the Dōjigiri, but also split in half the mat the bodies were laid on.

ENDING

A great deal was shared about the Dōjigiri and it reputation as a special sword both in application, design, and value. All of this documentation and events are what elevate it to a high-profile sword. That covers everything worth mentioning about the Dōjigiri Yasutsuna, illustrating why it is categorized as one of the Tenga Goken. Be on the look out for the last article in this series, which will be on the Odenta Mitsuyo.


1) While Shitennō literally means “4 Heavenly Kings”, in most cases it is a label reserved to 4 very strong & talented individuals. Think of it as 4 pillars to an establishment or group. For Yorimitsu’s group, these 4 individuals were Watanabe no Tsuna (渡辺綱), Sakata no Kintoki (坂田金時),  Usui Sadamitsu (碓井貞光), and Urabe Suetake (卜部季武). The other nickname commonly used is “Raikō Shitennō” (頼光四天王), with “Raiko” being the onyomi (音読み, Chinese-phonetic) reading of “Yorimitsu”. This double-reading of a name was an old practice usually done in honor of someone important or famous.

2) When drank by humans, the pronunciation of the name of this sake is the same, but instead uses the kanji “神変奇特酒” . This version of the name reads something like “mysteriously special wine of the Gods “.

3) Actually, Yorimitsu was not able to bring Shuten Dōji’s head back to the Imperial court, as it became “heavy” and unyielding on the way. This was forewarned while they passed through an area on the outskirts of the Capital that had a koyasu jizō (子安地蔵, statue of Jizō the guardian of childbirth) on the path, which warned them that no one was allowed to bring unclean things into the Capital city. It is thought that the guardian deity there caused this to protect the citizens, since Shuten Dōji was festering with germs, and it was highly possible his head would bring illnesses.

Having no other options, Yorimitsu dug up a tomb for the severed head, which would years later become the grounds for the shrine called Kubizuka Daimyōjin (首塚大明神). Consisting of a simple torii (gate), grave, and an altar, it is a small shrine where, through worshiping Shuten Dōji as a deity, all ailments the severed head was carrying has been lifted…at least, according to lore.

4) The same happened to the Onimaru Kunitsuna, which can be read here.

5) Katsuhime (勝姫) was more than a filler in the Tokugawa lineage; unlike many other women who have remained nameless, she is identified by her real name. This is due to her involvement in familial matters, which included land management and issues. Katsuhime is known under different titles during her lifetime, including the honorific title Takada-sama (高田様, Madame Takada), and her Buddhist name Tensuin (天崇院).

6) Life expectancy was low around this time, so it was not unusual for people to retire from their profession around their 40s or 50s.

7) To elaborate a little, it primarily remains in the possession of the Matsudaira from Tsuyama domain from 1698 up until modern times. Mitsunaga of the Matsudaira line from Echigo domain had a relatively long and intricately difficult time in his later years dealing with land ownership disputes with the Tokugawa Shogunate, which detracts too much from this article’s topic to go over. This also included losing ownership of treasured items temporarily, with the Dōjigiri being one of those possessions. These issues were eventually resolved while he was still alive, and he later had certain possessions, including the Dōjigiri, passed into the safe keeping of the Tsuyama-Matsudaira family line in a formal manner.

8) This, and all money values that follow are reported in Japanese yen, but not at present day’s rate. Note that there was not an official exchange rate of yen to US dollars from around the mid 1940s to early 1950s. This is primarily due to Japan’s lack of a unified currency system in society as a whole, as well as that yen was not yet part of the Bretton Woods system regarding affiliated global exchange rates. This would slowly change starting around around 1952.

Due to the lack of currency value structure for the Japanese yen at the time when the Dōjigiri was being purchased, attempts at a dollar to yen conversion will fluctuate abit, leading to possible (but not guaranteed) estimates. As a starter, the conversion rate between the mid 1940s to early 1950s would look something like $1 = ¥350 ~ ¥400.

9) This is based on the following inscription engraved on the sword, “備前国包平作” (Bizen no kuni Kanehira saku). This translates as “made by Kanehira of Bizen country”

Tenga Goken: The 5 Great Swords of Japan ~ Part 1

There are several icons related to Japan stand out. One of them being the katana. Both historically and culturally, there was a strong viewpoint regarding the importance of swords, way back when the warrior class still existed. In fact, there is the famous saying that “the sword is the soul of the warrior”¹. Although it was not the strongest weapon used during wars, it was nonetheless held at a high value, as a sword also represented status.

There are many stories about amazing swords coming from Japan, especially in fiction. Usually these stories are based on real versions crafted generations ago, which, in themselves, come with their own rumors and tales about being extra ordinary. Interestingly, there is one group of swords that are considered the best of their kind, known as “Tenga Goken” (天下五剣)², which can be read as “5 Great Swords of Japan” in English.

An auspicious example where tales paint a picture of a fine sword blade being enhanced through mystic means. Artwork entitled “Gekkō Zuihitsu Inabayama Kokaji”, a swordsmith by the name of Sanjō Munechika is helped by his family patreon deity Inari-myojin, who appears in child form. By Ogata Gekkō.

What could be so special about these swords that grant them such a title? What’s their origin? Who were the owners of each these five swords? Which ones were deemed supernatural? All of this will be covered in a multi-part series. Today’s article will be part 1 of this series, which will cover the origins of this claim. This will include the individuals who were experts in evaluating swords, along with recordings in the form of official documents that determine the quality level of these unique swords.

A WORD OF CAUTION

Before we proceed, let’s cover some notes that will give a broader view on this topic. While there are fairly aged books that have information regarding the Tenga Goken, it should be understood that a definitive name, along with cohesive details, were not nicely written in one go. On the contrary, it’s taken many generations, along with slightly varying descriptions, before we have an actual picture of said 5 great swords. However, is this picture real and accurate?

For starters, it is said that the following 5 swords make up the Tenga Goken:

  • Mikazuki Munechika (日月宗近)
  • Onimaru Kunitsuna (鬼丸国綱)
  • Dōjigiri Yasutsuna (童子切安綱)
  • Juzumaru Tsunetsugu (数珠丸恒次)
  • Odenta Mitsuyo (大典太光世)

These are judged as 5 exemplary swords, and were supposedly chosen sometime during the Muromachi period³. However, the individual(s) who made this assessment is unknown. On top of this, the label used to group these swords, Tenga Goken, was not originally as a headline for some listing. Instead, this was derived from descriptions regarding the 5 swords from said older documents. If anything, the name and the determination of the five swords grouped as Tenga Goken was something that came into play later in the Edo period. So, while this claim of 5 great swords may have been something finalized at a much later date, what we do know is that they do exist, and some documentation about them did take place. For what it’s worth, all 5 swords are said to still exist present day, and are in safe keeping as antiques. More about this in the upcoming articles.

ORIGINS WITH THE HONAMI CLAN

We get the 1st documentation that speaks on the Tenga Goken, which is called “Meikenden” (名劔伝). Part of the collection of the Tokyo National Museum, the Meikenden was compiled in 1769 in a document entitled, “Honnami-ke no Meibutsu Hikae-cho” (本阿彌家の名物扣帳). This is a listing of established blacksmiths around Japan, and swords that are their prized works. In listings like this, each sword is judged by certain traits, which will then put each into varying categories such as their grade of quality, being a visually fine piece of work, to having a unique story in its creation.

Here is the cover of the Meikenden (left), and the page that mentions the 5 swords that make up Tenga Goken (right). The swords are identified by a red mark above them.

So, who were the Honami clan and what was so special about them? They had a long history of being recognized as sword polishers, and later as experts in evaluating sword. In surviving records, the 1st head of this clan, Honami Myōhon, established his clan’s rise during the early Nanbokucho period (1337-1392) by being employed under Ashikaga Takauji, a war commander who would later establish the 1st shogunate under the Ashikaga rule and start the Muromachi bakufu around 1338. With Myōhon establishing this connection, the Honami clan became a dōboūshū (同朋衆) to the Ashikaga clan, which means they were personal artisans of whom were considered the most powerful at the time. Although being known to have such a prestigious relationship, the Honami clan didn’t just stay idle; they also took up the occupation as merchants and traveled abit throughout Japan over the centuries. Another point to take note is that, as their clan expanded, they also branched into other arts, such as calligraphy (書道, shodō), lacquer decorations using metal powder (蒔絵, makie), pottery (陶芸, tōgei) and tea ceremony (茶道, chadō).

OFFICIAL SWORD EVALUATIONS

It wasn’t until Honami Kōtoku, 9th successor, was recognized as an expert in sword evaluation, from where his clan was permitted in establishing methods for sword polishing, as well as determining the quality and style of swords being crafted. In due time, Honami Kōshitsu (本阿弥光室), the 10th successor, created a log in the form of an orihon (折本) that list detailed analysis on different swords of the time sometime between the late 1500s to early 1600s. While the Honami clan were famous due to their start by serving the Ashikaga shogunate, over the generations they also provided service to those who seeked their expertise. This includes Toyotomi Hideyoshi in the 1500s. Lastly, in 1719, when Tokugawa Yoshimune, 8th shogun of the Tokugawa shogunate, had the 13th successor Honami Kōchū commissioned to document the know-how about his clan’s lifework as sword polishers, Kōchū created a catalog called “Kyōhō Meibutsucho” (享保名物帳). It’s highly probable that this was used as one of the bases for in the aforementioned book, “Meikenden”.

DESCRIPTIONS OF 5 GREAT SWORDS

The next book of interest is “Shoka Meikenshu” (諸家名剣集), which was compiled in 1828. What’s interesting here is that this is a copy of the older book Kyōhō Meibutsucho, which is coupled with descriptions about each of the 5 swords. This is where we get many references that lead to the label “Tenga Goken”. Below are the pages from this book where each of these 5 swords are mentioned. The name of the sword and the particular phrase are indicated by a red line. (this is placed to the right of the text in the image) This will also be accompanied by the typed Japanese text, followed by my English transliteration.

Note that this sword and its descriptions are mentioned on a previous page (left), while the phrase above continues onto the following page (right)

鬼丸国綱
「右五振之内随一と申也」

Onimaru Kunitsuna
“To the right, this is said to be #1 out of the 5 swords”

Note that descriptions for this sword spans around 8 pages, and the phrase mentioned above appears on the 7th page (right)

童子切安綱
「誠天下出群之名刀ニ而右五振之内也」

Dōjigiri Yasutsuna

大典太光世

Odenta Mitsuyo

Key words to take away here are “5 swords” (五振) and “unrivaled” (天下). Although the word “unrivaled” appears for 3 out of the 5 swords, it’s most likely assumed that the other 2 swords should be of the same caliber if grouped in the same category.

ENDING

This concludes our look at the origins to the categorizing of the Tenga Goken. In the following articles more details will cover each sword, from the swordsmiths who made each one, to how they made their marks in history.


1) In Japanese, it is “katana wa bushi no tamashii” (刀は武士の魂).

2) Can also be pronounced “Tenka Goken”.

3) Note that the term for these swords used is “tachi” (太刀). In the past, swords were classified as a tachi based on having a bigger curve in the blade, meeting the standard length of a battlefield sword, and used while riding horseback. This is different from swords that were made for fighting on foot, such as the katana. On another note, the Tenga Goken were also praised as being works of art based on the craftsmanship that made them look magically appealing.

4) Note that there is 1 extra sword mentioned on the same page as the Tenga Goken in the book Meikenden, which is “Kanze Masamune” (観世正宗). This sword was made by the renown blacksmith group Masamune. While swords by Masamune are considered works of art in their own rights, they are not categorized along with the previous 5 swords, as the Tenga Goken were held in a class of their own years before this book was written.

5) This is read as go-furi (5 swords) in Japanese, whereas furi is a counter for swords as an object that is swung. Even though the word “sword” is not present, the counter itself lets the reader know what is being referenced here.
