no there not ALL Japanese, you can get some at gamestop.
You can buy Pokemon Black and White (JAP) almost anywhere in Japan. You could also order it from Nintendo's Japanese website, or perhaps Ebay.
Yes, it is possible to trade your UK Pokemon from Diamond into the Japanese Pokemon Black version. However, you need to beat the whole game in Pokemon Black & White to be able to trade Pokemon from the other generations.
Right now, Pokemon Black and White are only available in Japan in Japanese. The English version wont be out until spring 2011.
The game will come out on June 2012...But it in JAPANESE GAME..and english version maybe come out on late of the year..
