Tamiya Ryu Iaijutsu

Tamiya Ryu

Tamiya Ryu Iaijutsu is a military art (bugei) that was introduced in the Tensho period (1573-1591) by its founder, Tamiya Heibei Narimasa. Narimasa, together with Katayama Hoki no kami Hisayasu (the founder of Hoki Ryu) and Sekiguchi Jushin (the founder of Sekiguchi Ryu) were pupiles of Hayashizake Jinsuke Shigenobu, the founder of iaijutsu.

The style characteristics of the Tamiya school of swordsmenship are: First volume (Omote no maki) containing evelen kata and Second volume (Koran no maki) containing fourteen kata.


Iaijutsu is a martial art (bujutsu) that strives to supress a sudden attack by the attacker against the defender using a single, swift stroke of the sword and seeks to master the various principles of drawing, re-sheathing and using the sword.

Furthermore, iaijutsu is a martial way (budo) as it practiced with a humble and modest heart and continually trains the spirit.

As a serious course of study, learning Tamiya Ryu Iaijutsu involves having a clear understanding of the concepts known as "Tamiya Nobility" and "Tamiya Purity"
