Didn't the Samurai have something similar to the original platonic homo-erotic teachter-pupil relation? There was this japanese writer who wanted to start a traditional revolution in the 1960s or 70s and then committed ritualistic suicide. I think, such stuff was going on in his circle.
Yes that is what I meant indeed. I think it comes from that original teacher-pupil dynamic and grew into a sub culture of some sorts. I think there is even a word for it.
You mean Yukio Mishima? He was an interesting fella.
