I saw Shark Skin Man and Peach Hip Girl last night.  It's one of those Terantino-style Japanese gangster movie with odd sense of humor.  Among all the funny characters in the movie, I thought Yamada stood out clearly.  Yamada is a weird homosextual assassin/ham radio operator who starts out like a total pervert and turns into a bumbling heroic character who exits his role skewered by a samurai sword.  The movie as a whole was not very memorable, but Yamada sure was.  Watch the movie just to get your dose of Yamada.
