Kuroda sensei began his training at the age of 5 and was trained by
both his father and his grandfather Kuroda Yasuji. Komagawa Kaishin ryu kenjutsu was founded by Komagawa
Tarouzaemon-kunikichi. Kaishin is composed of two words kai and shin. Kai
means change and shin means mind or spirit. Kaishin means changed mind or
spirit. This style of kenjutsu was founded 450 years ago.
Kuroda Tetsuzan is an outstanding swordsman in the Japanese
tradition. He is almost magically fast at iaijitsu. These abilities come from training from a very early age in a system that has a very sophisticated theories and operating system. As in a classical Samurai bugei Shishin-Takuma ryu jujitsu integrates with the kenjitsu. It is a
very soft subtle form of Jujitsu which would be called by many a very
sophisticated aiki application. Kuroda sensei does not use the word aiki.
When this word was becoming popular his grandfather Yasuji felt that all
jujitsu should be that subtle and there was no need for a word to describe
When training with Kuroda sensei several arts are studied the
kenjitsu, iaijitsu, and jujitsu which have been mentioned also included are
the jo and the jutte. Mental training is an integral part of the training
regardless of weapon used. Kuroda sensei is dedicated to keeping these
ancient Samurai tradtions alive in the modern world.
