I bought this game not knowing a single kanji so I was prepared for trial and error. Losing a battle doesnt set you back much which makes trying again painless.
The battles are fun and its a blast to learn more kanji to attack with! Though as ScPpY said, the game isnt for teaching you how to write kanji, only recognize it.
Even for someone like me who doesnt know Japanese, this game is still fun to play. If you have even a slight care about Japanese, you cant go wrong with this game!
