About Tenshin-ryu Hyoho
Tenshin-ryu Hyoho is a present-day Japanese group that, according to its own website, teaches swordsmanship and other martial arts. The same website says it was founded about 400 years ago, in the Kan'ei era, by Tokizawa Yahei, who studied Shinkage-ryu under Yagyu Munenori. The school writes that it is the only one in Japan to pass on this style in an unbroken line. We did not find it in the lists of the Nihon Kobudo Kyokai or the Nihon Kobudo Shinkokai. We also found no encyclopedia article, no mention on koryu.com and no scholarly paper on its origin. Japanese Wikipedia states that the original Tenshin-ryu of Tokizawa Yahei died out and its content is unknown. According to the same source, the present-day group claims continuity only on the basis of oral tradition, which does not agree with the other historical sources. What we could document is its current activity. The Japanese news site J-CAST wrote in 2020 about the group as advisers on combat movement for the video game Ghost of Tsushima. The description of its origin in the article comes from the group itself. We could not document the year of founding or the founder from an independent source.
History
According to the school's website, Tenshin-ryu was founded in the Kan'ei era by Tokizawa Yahei, a Shinkage-ryu student of Yagyu Munenori. The site also claims the school grew out of a hidden corps protecting the Tokugawa house, whose members served Munenori. Japanese Wikipedia says commentators called this story invented history. Japanese Wikipedia also mentions an original Tenshin-ryu, founded in the Kan'ei era by Tokizawa Yahei after studying Shinkage-ryu under Yagyu Munenori. It says this school died out and we know nothing of its content. According to the same source, the present-day group states that the tradition passed through several families and reached Tokyo after the Meiji period. In 2025 the school's website wrote that the Kansai branch of the tradition has died out, leaving only the Ishii family transmission from the Kanto region.
How it differs
The school's website explicitly states that other schools named Tenshin-ryu are unrelated to it and that one of them already had the plainer name Tenshin-ryu registered as a trademark. According to the same website, the group registered the longer name Edo Yagyu Tenshin-ryu Hyoho. Tenshin Buko-ryu, led by the Nihon Kobudo Shinkokai, must also be told apart from Tenshin-ryu Hyoho. It is a different school.
Technique
According to the school's website, Tenshin-ryu Hyoho teaches battojutsu sword drawing, kenjutsu swordsmanship and yawara, that is jujutsu. The website divides teaching into katsujinken, kodachi battojutsu, kenjutsu and battojutsu. In a 2020 statement to J-CAST the group said it is not swordsmanship as a martial art but a different current. On its website it describes its swordsmanship as a sword for castle service and calls it joshi no ken.
Today
The school's website lists Nakamura Tenshin as the ninth head, Kuwami Masakumo as the tenth and Ide Ryusetsu as the eleventh. According to Japanese Wikipedia, the group is today led by Kuwami Masakumo and Ide Ryusetsu, is based in Yokohama and operates mainly in Kanagawa and Tokyo. J-CAST in 2020 described the group as advisers on combat movement for the video game Ghost of Tsushima. The school's website lists seminars abroad, including in Austria, and an instructional video with English subtitles.
Did you know
According to J-CAST, the group became famous in 2017 through a video posted on Twitter by the deputy instructor Takizawa Dofu. In it he showed swordsmanship in a maid costume. The school's website says the office approved the trademark Edo Yagyu Tenshin-ryu Hyoho on 30 October 2015. It gives as the reason for the application a warning that an unrelated party would try to register the name. We could not verify this in the office's register.
