Kutabare akutô-domo: Tantei jimusho 23

A detective goes undercover with the yakuza in an effort to expose their criminal ring. He's got a crew with him but is found out pretty fast. He has to think on his feet to stay alive and catch the bad guys.

Jo Shishido and his giant chipmunk cheeks swaggers through this movie, and even gets to sing and dance, but the story itself is pretty slight and the action is a little bland. It's was obviously meant to start a series but didn't pan out. It's certainly not terrible but it is a little on the meh side. If you love yakuza movies on the lighter side or have to see every Shishido movie then you'll probably dig it, otherwise it's a skipper.
