Kagami Biraki: Open Up to Good Fortune ~ Part 1

There are many martial arts groups that open the new year in Japan with a ceremony called “Kagami Biraki” (鏡開き). Along with how it’s utilized for the sake of auspicious readings and praying for year-long fortune by shrines and temples, this ceremony is conducted for the sake of good luck during year-long martial training sessions. Its purpose is symbolically significant that my Chikushin group has also adopted this to promote a safe & healthy training year. For this article, we’ll first explore how this ceremony is conducted, by looking at a few events that really illustrate the theme for the new year.


Today, Kagami Biraki is used as an opening ceremony for many martial arts groups and organizations. It can be either a small gathering among those who are associated with said group, to a large gathering in a form of a collaboration between different organizations. Well established groups such as Maniwa Nen ryū and Kōdōkan Judō Institute hold this ceremony among their own members, as an example. These smaller events may commence with a speech or formal new year blessing, then followed by technique demonstrations. At the end, there may be  traditional sweets and treats associated with the ceremony that are made available to participants, such as mikan (みかん, mandarin orange). Depending on their tradition, visitors may be allowed to view these groups’ ceremony.

One of the largest, most publicized of these events is “Kagami Biraki-shiki & Budō Hajime” (鏡開式・武道始), which is conducted at the Nihon Budōkan in Tokyo City, Japan. This is an event that has two parts, first being the Kagami Biraki ceremony, then followed by the martial arts segment. Dozens of different martial arts schools, both traditional and modern, participate to present their unique systems.

Let’s look at how Kagami Biraki takes place at the Nihon Budōkan. For the ceremony portion there are 3 parts¹. It starts off with “Yoroi Kizome” (鎧着始め), where individuals dressed in Japanese armor give tribute to the roots of combat to those warriors that fought during warring times. Next is “Sankon no Gi” (三献の儀), where the sōdaishō (総大将, commander-in-chief) does a ritualistic consumption of kachiguri (勝ち栗, dried walnuts), uchi awabi (打ち鮑, dried abalone), and konbu (昆布, kelp) alongside with sake (酒, rice wine) for the sake of gaining luck before going into battle. Finally, “Kagami Biraki” portion takes place, where the sōdaishō uses a small mallet to break the top layer of a kagami mochi (鏡餅, 2-tier decorated rice cake), while his second-in-command officers split the lid on a taruzake (樽酒, barrel filled with special rice wine).  All of this is symbolic, and is considered important to promote the true spirit when engaging in Japanese martial arts.

Next is the training portion, which usually is conducted in the form of demonstrations by each participating group. It is a mix of groups that specialize in modern, sports-oriented styles, and traditional styles. So you may see one group that’ll demonstrate kyūdō (弓道, way of archery), and another demonstrate a version of karate.  There are usually groups that are involved in iaidō (居合道, way of drawing the sword), sōjutsu (槍術, spear techniques), or naginatajutsu (薙刀術, glaive techniques). Over the years, this event had demonstrations of hōjutsu (砲術, gunnery techniques), jukendō (銃剣道, way of the bayonet), and even sumō wrestling. Every year, the participating groups may differ, so there may be variations in what types of styles are presented. After all the demonstrations are over, the floor is open for everyone to take part in hatsu geiko (初稽古, first practice session). A good variety of practitioners, both young and old, can be seen training together. Finally, this ends with an oshiruko kai (おしるこ会, sweet red bean soup event), where everyone can sit together and replenish their energy with this tasty treat.

Take note that each Kagami Biraki event has its own date in which it takes place. For the one that is held at the Nihon Budōkan, it’s held on the 11th of January. Unfortunately, this event was canceled due to the precaution against the current pandemic inflicting the world. For those interested, there are vids on Youtube that showcase these Kagami Biraki events. To see the one held at the Nihon Budōkan, I recommend the following video found on Budo Japan Channel, as it covers the explanation in this article very closely.


The connection that Kagami Biraki has with Japanese martial arts is considered a deep one. Every year many groups and organizations go to great lengths in organizing events where practitioners can feel they can begin their training in the new year on the right foot. Unfortunately, since a great number of participants are pulled in every year for this, many Kagami Biraki events have been canceled due to the current restrictions. As a substitute, it’s possible that these groups may have performed a smaller ceremony just for direct members.

Be on the lookout of the 2nd art on the topic of Kagami Biraki. In the next one, we will look into the actual history behind this ceremony, look deeper into some of the components that were briefly mentioned, and get an understanding of how it’s celebrated by the general public and through religious establishments.
