There is only one Shinto Muso Ryu Jojitsu. The meaning of Shinto or Shindo is almost the same. Shinto means "the divine way". Nowadays, Shindo means "the true way". Later, this name was adjusted by Shimizu Takaji in to Shindo Muso Ryu Jodo. (1939) Many system names changed in a later period by the popular addition"do". We will call it "Shindo Muso Ryu Jodo".
There is only one way to practice and study Shindo Muso Ryu Jodo. The name "Seitei" was introduced in 1968 by the Japanese Kendo
Federation. During that time the examination requirements for this Federation were modified. Cadidates for Nidan in Kendo needed some knowledge of Shindo Muso Ryu Jodo. At the request of this
Federation Shimizu Takaji Shihan has chosen 12 kata. So far no problem, because seitei
was only meant for the Zen Nippon Kendo Renmei and no one else. But... Western people made unbeseeming abuse of this situation and pretended that this is (modern) Jodo. Nowadays among western insistence this is even supported by japanese(!) It's incomplete and does not cover the original Jodo of the
Shindo Muso Ryu. The
execution is literally step-by-step with too long breaks. During
the process of learning that's very well indeed. But eventually the kata must be performed as originally intended. Although, there's world wide some improvement, but unfortunately not in all cases.
2 QUESTIONS for reflection...
a Can you change Beethoven's 5th Symphony and keep calling it Beethoven's 5th Symphony?
b Can you change the Night Watch by Rembrandt van Rijn and then continue to call it the Night Watch by Rembrandt?
