打倒…afaik
Thanks Pertti. That may well be the correct modern kanji for tou, which would make the meaning of the technique ‘to overthrow’ which seems appropriate.
However the kanji used is 木へんに口. This would appear to be a relatively simple kanji, but I can find no reference to it in books, denshi jisho or similar places. It could be an obsolete form of 倒.
To see this kanji have a look at the Quest Ninja Biken DVD or in Hatsumi’s Japanese Sword Fighting pg 61 there is Dato no Kamae – so it can be printed, but why can’t it be found? Must be some some sort of ninja obfuscation…
o 打椢
I think this is what your looking for
..or this 打扣?
A Japanese friend asked her mother about this kanji – she says she can vaguely recall it – but it is a very old kanji and she can’t remember what it means, yet…
I have someone else in Japan who should get back soon.
I had considered 椢 and 扣, the former would end up as an odd meaning and the second makes sense for a compound meaning ‘to strike’ as in the Koto waza.
