Taisha-ryū (タイ捨流) is a comprehensive martial tradition of southern Japan, founded in the late sixteenth century by Marume Kurando Nagayoshi. Marume was among the closest pupils of Kamiizumi Nobutsuna, the swordsman who created Shinkage-ryū, and Taisha-ryū carries that descent into the warrior culture of Kyūshū, where it has been preserved for centuries.
Marume Kurando
Marume Kurando Nagayoshi (1540 to 1629) is a genuinely historical figure who received a high licence from Kamiizumi and later served the Sagara house of the Hitoyoshi domain in Higo, in what is now Kumamoto Prefecture. He taught there in his later years, and the school took root in that region rather than in the capital.
Win before the blade is drawn by shaping the ground, the distance and the moment.
A whole-warrior curriculum
Though the sword sits at its centre, Taisha-ryū was conceived as a complete battlefield art and historically took in the naginata, the spear and other skills. It is noted for its attention to terrain, to deception and to the use of the voice, the kiai, treating a fight as a problem of position and timing as much as of blade against blade.
The name
The name is written in a way that suggests discarding or casting aside the self, a reading often connected to the school's emphasis on shedding hesitation and fixed intent. As with much in the older traditions, the deeper meaning is interpreted in more than one way.
Honesty note
Marume himself is well attested, but the fine detail of the earliest curriculum and its changes across four centuries is less certain. The art survives as a living koryū centred on the Hitoyoshi and Kuma region of Kyūshū.
