We continue with part 2 regarding the true image of Sanada Yukimura. In part 1 we established that his real name was Nobushige, took a brief overview of his historical bio, and examined the source behind the label “Yukimura” along with the idea behind it. In this post we will look at the fictional side spurred on by the Yukimura image, and how real life accounts fit into this. Take note that when addressing non-academic source materials such as movies and novels, one should not automatically assume that these are completely false info which can can be discarded in a blink of the eye. Depending on the author/director’s intentions, these could very much follow along accurately with historical events in order to make a solid and entertaining story. They may even contain info that tends to be difficult to find. However, what is important is to recognize which points are fiction in these works, and how to discern the correct info that can be compared to factual sources.
PERSONALITY OF A HERO
When analyzing the image of Sanada Yukimura, we see him represented as one of Japan’s greatest war heroes. This is in part to how he’s portrayed in novels, shows, and movies, both old and new. Depending on the literary work, Yukimura is given a personality that portrays him as stoic, righteous, and heroic figure. This is common especially if the individual is the main character. He is usually depicted as one who stands by his principles and doing whatever it takes to ensure victory, especially for the Toyotomi family. In instances regarding the Osaka Campaign, Yukimura is shown leading his troops head-on into the thick of battle, while in others he is resourceful with carefully analyzed plans that lead to successful outcome. One of the themes that is considered memorable is him commanding his elite warriors and having them operate as kagemusha (影武者, body double) of himself, which was a deceptive tactic to disrupt the enemies’ focus and lower their morality as they get overwhelmed dealing with multiple “Yukimura”.
Take this as an example. In the novel “Chōbō Sanada Yukimura” (智謀真田幸村), Yukimura is shown to be ever protective of his master, Hideyoshi Hideyori after the defeat during the Osaka Campaign. As an escape to Sasshū Province (western part of present-day Kagoshima prefecture) has been established, he is portrayed saying the following lines to a fellow comrade named Gotō Matabei¹:
…considering things from where I stand right now, I want to prevent my lord from dying in this war, if granted such an opportunity”
”On top of this, my thoughts are to gather a number of people, and have them reestablish the Toyotomi clan through the help of the Shimazu (Shimadzu) clan. Through this, I would want to have someone play your double, and then have him die in (the next) battle where everyone can see.”
To the very end, Yukimura dedicates his life in preserving the true Toyotomi line, even when the odds are surely against them. Establishing a new Toyotomi family, and using doubles for certain individuals that would continue the fight and eventually die at the hands of Tokugawa Shogunate would stop any pursuers coming for them. As impressive as this may sound, this is just a novel. Yet, this also goes in hand with the narrative regarding him avoiding death and managing to survive Osaka Campaign.
In fictional works there tends to be characters that don’t have a real historical presence, but used for the sake of the story. In the various novels that feature Yukimura, there are cases of this, sometimes being minor individuals who help to fill in the gaps where history leaves open. Other times a real figure is used to model a new character placed in the story. Since literary works regarding Sanada Yukimura were stated to be based on true events in the past, like many other novels of its kind, future generation may inadvertently mistaken fictional characters as to being actual people.
Other than Yukimura himself, possibly the largest example of fictional characters is found in the “Sanada Jūyūshi” (真田十勇士), which is a label given to 10 brave warriors representing families that were allies to the Sanada clan. The appearance of this Sanada Jūyūshi is often attributed to “Sanada Sandaiki” (真田三代記), a Sanada-supportive narrative produced in the Edo period. Although viewed as fictional, these characters grew in popularity and appeared in modern-day novels, manga, movies, and the like. Some of the individuals even appeared in works centering about them, which further developed their background story to the point where they sound like they truly came out from the pages of history. The following is a list of the those individuals of the Sanada Jūyūshi²:
- Sarutobi Sasuke (猿飛佐助) – a famous ninja employed by the Sanada clan, he is said to be the student of the legendary Koka ryu ninjutsu master named Tozawa Hakuunsai.
- Kirigakure Saizō (霧隠才蔵) – a ninja who was the student of Momochi Sandayu, lord of one of the 3 powerful families of Iga Prefecture.
- Miyoshi Seikai Nyūdō (三好清海入道) – A monk employed by Yukimura who is renown as a hero fighting to his death during the Osaka Campaign.
- Miyoshi Isa Nyūdō (三好伊三入道) – Younger brother of Sekai who was also a monk, and hailed as a hero dying in battle during the Osaka Campaign.
- Anayama Kosuke (穴山 こすけ) – A dedicated retainer of Yukimura, he played the double of his master during the Osaka Campaign.
- Yuri Kamanosuke (由利鎌之助) – Once a retainer of Toda Suganuma, he switched to the Sanada side after the Toda were defeated in battle.
- Kakei Jūzō (筧十蔵) – From the Kakei family, allies of the Sanada clan. Apart from Jūzō, other members of the Kakei family also appear in different Sanada-related stories.
- Unno Rokurō (海野六郎) – A fellow kinsman, as his family line is from where the Sanada line originates from.
- Nezu Jinpachi (根津甚八) – Once a pirate for the Kuki navy, he later becomes a retainer of Yukimura. His family line, like the Sanada line, also originates from the Unno line.
- Mochizuki Rokurō (望月六郎) – A mysterious ally of Yukimura who specializes in explosives. Rokurō is also known under different titles depending on the story he appears in.
Note that while they make up the Jūyūshi due to their inclusion in various works as allies of Yukimura since as early as the Edo period, this wasn’t an official title for them until sometime in the late 1800s to early 1900s. Some other things worth mentioning is that while these characters are deemed fictional, most of them are considered to have been inspired by actual people from history. For example, the concept of Sarutobi Sasuke is believed to have been based off of one of several different individuals whose names appear in different texts. The most popular theory is Sarutobi Nisuke³ (猿飛仁助), who is said to have been a thief hired to assist in the “Battle of Kanegasaki” (金ヶ崎の戦い) by a Kinoshita Tokichirō (木下藤吉郎) in 1570⁴. In another example, Miyoshi Sekai and his brother are believed to have been modeled after Miyoshi Masakatsu (三好政勝) and his family. Masakatsu became head of the Miyoshi clan and served under Hosokawa Harumoto after his father, Miyoshi Masanaga (三好政長), retired.
A staple that will probably be forever associated with Sanada Yukimura is red armor. This is something Yukimura and his troops donned on right before the Osaka Campaign. The concept of wearing red armor is thought to be intimidating due to its fiery color. It’s said that it has such a psychological effect on his enemy Tokugawa Ieyasu that his umajirushi (馬印, a battle flag on a pole inserted into a slot on the back of one’s armor) fell down, which is said to be a bad omen. Yukimura is, with no hesitation, depicted in red armor in novels and visual in artworks from Edo period. Due to these, the trend continues in modern times. This association to the red armor is not limited to Yukimura, for the Sanada clan as a whole is included as well.
Of course, this claim of red armor doesn’t come without critical disputes. One of the more recent claims is that the Sanada red armor is just as much as a myth as the name Yukimura, for this famed red armor of his (Nobushige’s) has yet to be claimed and placed in a museum. One argument is that the actual armor that Nobushige wore was found, and that it was actually black. Another argument is that within certain households in Japan that have some form of link to the Sanada clan have preserved these old red armor, but the color is not a vibrant red but a dull brownish-red color. Considering how wars in the past were conducted, it is not unusual for certain things like armor to have been taken by the victor, or lost during the chaotic fray. Interestingly, in 2017 there was an article in a Japanese newspaper regarding family in Nagano, Japan coming forth with what looks to be the remains of a very old red armor, along with an aged note stating it was the possession of the Sanada clan. It was up on display at the Sanada Hobutsukan (真田宝物館, Sanada Sacred Treasures Museum) that same year.
As a side note, the idea of wearing red armor isn’t an original concept by the Sanada clan, nor was it a rare sight. Historical sources point to the warlord of Kai province, Takeda Shingen, as being the first to devise this strategy around the mid 1500s. It’s said that the goal was intimidation of the opposition with this type of color. Shingen had a designated team of soldiers wear red armor in order to catch the enemy force’s eyes and instill fear as they rushed into battle. It is from here which Sanada Masayuki (Nobushige’s father) adopted the idea of red armor within his clan. Whether or not members of the Sanada clan donned on red armor prior to the events in Osaka Campaign is still up for debate, but there is one evidence that points to this as being a thing. In Hirayama Masaru’s book “Sanada Nobuyuki: Chichi no Chiryaku ni katta Ketsudan-ryoku” (真田信之 父の知略に勝った決断力), he reveals that when an order from Toyotomi Hideyoshi came regarding being prepared for military service in 1593, Sanada Nobuyuki (Nobushige’s older brother) replied that the warriors of the Sanada clan were always ready to serve while donning on red armor. Years later, during the Battle of Sekigahara a retainer of Tokugawa Ieyasu known as Ii Naomasa (井伊直政) also adopted the idea of wearing red armor and outfitted his troops the same way. What’s unique in this is that he was a comrade to Nobuyuki, who at the time sided with the Tokugawa-Eastern forces as ordered by his father Masayuki as a means to ensure the Sanada line survives no matter which side wins.
SANADA = NINJA?!?
Since the Edo period all the way to the present, the Sanada clan is presented as heavily associated with ninja. Employing a large number of these shadowy figures, ninja from both the regions of Iga and Koga are portrayed as serving Sanada members like Masayuki, Nobuyuki, and Yukimura. While it starts off small in earlier works in the Edo period, this image became more pronounced in later works such as novel Sanada Sandaiki, where all 10 members of the Jūyūshi are ninja or related to a ninja. This even lead to more focus on the ninja theme in modern works, including movies such as “Ninjutsu Sanada Jūyūshi” (忍術真田十勇士) and “Sanada Fuunroku” (真田風雲録), as well as 2016 drama “Sanada-Maru” (真田丸)⁵.
What is the reason behind this large focus on ninja being employed by the Sanada clan? Is it just a ploy to bolster the image of Yukimura (Nobushige), which in turn developed into its own entity entirely? In some ways, yes. However, this is not a baseless creation or idea. There are records that point to the Sanada clan having a working relationship with different groups that specialized in the fundamental skills that would become what we call “ninjutsu” in modern days. According to some, the Sanada clan are also said to have engaged in ninja-like activities themselves. The root of this is generally connected to Takeda Shingen and when he was ruler of Kai Province during the early-mid 1500s. Shingen is recorded as utilizing not only a network of different groups taking part in espionage and information-gathering, but establishing an in-house system of ninjutsu, which a select number of his generals were privy to learning in order to assist in maintaining it. At the time, Sanada Yukitaka (Nobushige’s grandfather) was serving Shingen and not only had knowledge of utilizing ninja, but is said to have taken part in ninja-like operations. Yukitaka’s son Sanada Masayuki would continue this as one of the 24 top generals of the Takeda clan. In fact, some claim that after Takeda Shingen’s death and the fall of the Takeda clan, Masayuki would keep up this network of utilizing ninja.
One piece of evidence for this is found in an old historical memoir called Kazawaki (加沢記), which is an account of activities that took place in areas around Kosuke Province (present-day Gunma prefecture) during the 1500s. Ninja-like groups from Higashi Agazuma area (東吾妻方地) are written to have been utilized by Takeda Shingen and members of the Sanada Clan. This is significant due to Higashi Agazuma area featuring densely wooded routes that were used not only by the local ninja, but it said that members of the Sanada clan also had access to these as well.
This leads to the famed Yukimura and his Jūyūshi. The ninja members such as Kirigakure Saizō have been identified as fictional characters. Claims are that they were inspired by real life figures who may not have actually had any connections with Yukimura. Yet, could it be that there were actual ninja working closely to him? There is one that is worth mentioning. Sources point to the Yokotani family (横谷氏), who are said to have been ninja from Shinano Province (part of present-day Nagano Prefecture). While there is not a lot of info on them, it is believed that they were active throughout the 1500s to about the early 1600s as members of a ninja group from Agazuma area, who were under the employment of Ideura Morikiyo (出浦 盛清), a vassal of the Sanada clan. Notable members are Yokotani Yukishige (横谷幸重), who is said to have served Sanada Nobuyuki (Nobushige’s older brother), while his younger brother Yokotani Shigeuji (横谷重氏) had served Nobushige. Shigeuji, who also went by the title “Sakon” (左近), died during Osaka Campaign, just like others who were serving Nobushige during the battle. Some researchers believe that Yokotani Shigeuji could have inspired the idea of Sarutobi Sasuke, but this hasn’t been proven yet.
So the idea of a ninja employed under Nobushige, fighting during the Osaka Campaign, and dying as possibly a kagemusha for him is a strong possibility. On top of that, with the Sanada clan’s deep connection with utilizing ninja groups, it can be understood why they are presented the way they are. However, it is too far of a stretch to say everyone around Nobushige was a ninja, and that the Jūyūshi were composed entirely of them. See, when you have a forced portrayal of Miyoshi Seikai Nyūdō being the son of the fictional thief ninja Ishikawa Goemon as depicted in Shibata Renzaborū’s novel “Sanada Yukimura~Sanada Jūyūshi” (真田幸村～真田十勇士), it’s hard not to say that this is due to the popularity of ninja in modern society.
Here we conclude the discussion on this famous hero. In ending, writing about Sanada Yukimura (Nobushige) is a tough topic to pick up and try to address from a historical point of view. To be exact, this was a several months-long project, which included acquiring a Sanada-related books, reading through well-known novels, researching historical sources, and going through sites that spoke about both the real side and the fictional side of Yukimura, to say the least. In the long run, due to how history was recorded hundreds of years ago, it is hard to get a definitive answer on certain points, especially when writers add their creative perspective to make a war story sound more epic.
1) Chapter 54, page 431
2) Depending on the source material, some of these characters bear a different name or are presented in a revised way. The one above is a standard listing.
3) The credibility of the source that mentions Sarutobi Nisuke is also under scrutiny, thus historians feel that he may have been made up to fit some agenda.
4) This was another alias used by Toyotomi Hideyoshi, a warlord who managed to seize control of Japan in the later part of the 1500s
5) The terms ninja and ninjutsu are used loosely here, as they are modern words used to identify those who engaged in clandestine activities such as spying, and information gathering. While in the past there were different labels depending on the region and who they were employed by, the universal term was often considered to be shinobi (忍び), and their methods called shinobi-no-jutsu (忍びの術). For the sake of ease in understanding for casual readers, the terms ninja and ninjutsu were chosen to be used in this article.
