There is a sub game where you can play with a japanese sub: Cold Waters with the mod "More subs and more", but it's a sub sim in modern times, not a WWII sub game.
The subs you could play there are the SS Yushio and SS Oyashio. In the current version of CW (v.1.09) they have added a Chineese Campaign so using this mod would make sense I think.
