Lineage (系図) in martial arts traces the heritage and transmission of knowledge from one generation to the next. This unbroken chain of masters and students is central to the preservation and integrity of the martial tradition, ensuring that teachings remain pure and authentic over time. Understanding a martial art’s lineage offers insight into distinct history, techniques, and philosophies.

Iaijutsu (居合術) is the art in which one draws the sword and strikes the opponent in one single movement with the Spirit (精神), the Body (身体), and the Sword () as one. There are several styles of Iaijutsu that are still practised today. They are mainly the following:

The Tokyo Adachi Roshukai is a group dedicated to the study of Muso Jikiden Eishin Ryu (MJER) Iaijutsu of the Yamauchi Branch.

Our Lineage

Muso Jikiden Eishin Ryu originates from Tosa Province (modern day Kochi Prefecture), an extensive area of Japan which was ruled by the Yamauchi clan throughout the Edo Period.

Yamanouchi Toyotake Sensei (1903 - 1946) held the title of Viscount and was a direct student of 17th generation Oe Masaji / Masamichi Sensei (1852 - 1927). He was one of a handful of 18th generation students to receive the Iaijutsu Kongen no Maki (根源の巻), a scroll signifying complete transmission of the school.

Yamauchi Sensei had learned Yagyu Shinkage Ryu (柳生新陰流 - “Yagyu New Shadow School”) and because the Yamauchi family were the lords of Tosa region, he also learned the local art – what we commonly now refer to as Muso Jikiden Eishin Ryu. However, as the grandson of Daimyo Yamauchi Yodo, Oe Sensei’s former lord, he was taught Iai befitting a lord. While the core forms remain the same, this manifests through small stylistic differences from other branches of MJER. Yamauchi Toyotake Sensei published the ‘Iai Shousetsu’ formalising some of the knowledge of our school in writing for the first time publicly.

The 20th generation master, Onoue Masamitsu Sensei, inherited the Meibukan Dojo.

The Tokyo Adachi Roshukai was formed and led by 21st generation master Honda Masayoshi Jushin Sensei (1936 – 2022) who was awarded Iaijutsu Kongen no Maki from his teacher Onoue Masamitsu Sensei also held the rank of Kyoshi 7dan from the ZNKR. Honda Sensei was also a student of Iwata Norikazu Sensei, the founder of the Roshukai.

Honda Masayoshi Jushin Sensei devoted himself to the practice of Iai for over 50 years and formed and led the Adachi Roshukai branch for over three decades. His strength of character and passion for Iai was an inspiration for many students both in Japan and around the world.

Honda Sensei was posthumously awarded a Kensho-jo (顕彰状, official commendation) from the ZNKR in 2023 for his contribution to the federation and development of Iai.

The Tokyo Adachi Roshukai UK is honored to use the Honda family crest (Honda-shi), acknowledging our deep connection to our Japanese origins, also signifying the trust and friendship established between Honda Masayoshi Jushin Sensei and our Dojo-cho.

In the spirit of Iaido, below is a glimpse into some of the Shoden (初伝) - or foundational entry level kata that shape our TAR syllabus. These forms serve as an introduction to the deeper, silent teachings that underpin our lineage’s rich history. These Shoden forms alone are enough to keep even the most avid practitioner busy for a lifetime, if not two lifetimes. Once a clear understanding and skill is developed, the student is then permitted to learn and practice deeper level Shoden forms and also introduced into the next higher forms.
