NO, the 3DS have a region block, only American 3DS can play American games and only pal 3DS (from Europe) can play pal games and also only Japanese games can be played on a Japanese 3DS

Buy a japaneze game! I meant after you've bought a Japanese game what kind of freeload/software is there that lets you play imported-Japanese games?
Unfortunately, no. The Japanese games would have to be manually programmed to support English, and very very few are. The Pokemon games, for example, do not have English translations in them.
