The game is great. I don't know any japanese and I figured it out and actually learned a little(not how to pronounce though). I used a guide on the internet when it came down to the real nitty gritty though. That and fining out which characters to upgrade. The game is extremely fun and addicting and you will spend hour after hour trying to get every character (I still don't have them all and I have had it close to a year).
Overall, it's like Super Smash Bros with stamina mode on (the characters have health bars) with a gazillion Jump character. I recomend fully upgrading luffy or ichigo, they are really good.
Also, another good import is Ganbare Goemon DS (mystical ninja). So fun!
