Importing Japanese RPGs

Looking back at the history of gaming, there has always been a number of great RPGs that never made it to America. If one was to import some of these games, would they be playable at all if you're not familiar with the japanese language? Are there online guides anywhere to walk you through these games? Or do any of them have an English language setting?

Well you could learn Japanese, I would think using a guide would ruin the point in playing the game and you really need to be reading in an RPG anyway.

I'd say that you wouldn't enjoy the game without learning a good bit of Japanese.
