Thanks - interesting reading. Looks like you're right - no big mystery.
From that article:
My father taught him only the first or second technique. He complained of a lot of pain and so he learned the rest of the techniques by correspondence. Then he later combined our techniques with Nihon Kenpo and created Shorinji Kenpo.
Err...what? This seems to suggest that the founder of Shorinji kempo couldn't take a nikkyo...
