Bun Bu Ichi
I am looking for a Japanese language reference in which the term Bun Bu Ichi is used. In English-language Budo texts the term is often used, but I can't find it in Japanese.
I have found lots of texts in Japanese where the equivalent Bun Bu Ryodo is used, but I cannot seem to find anything in Japanese where Bun Bu Ichi is used. A Japanese-language Google search only brings up Chinese texts! Any help to be found out there?
