Read Natsume Soseki's [Kokoro] to check if it does have homosexual under/overtones like many psychologists and literary critics have pointed out.

It sort of does, at least up to the part when "I" is the protagonist. Practically stalking an older man for no particular reason whatsover wasn't normal even by Meiji Japan standards...which is why he is suspected as being gay even in the book. But overall, it was a philosophical and insightful look on the nature of human existence and mind.

For those of you who haven't read Soseki yet, I highly recommend his works for their clarity and insight. [Botchan] and [I am a cat] are nice starters; especially [Botchan] is witty and hilarious even by today's standards.
