Difference btw American version wii and Japan version wii

因為wii的遊戲有別碼之分，故此：
1.美版和日版的最大分別便是日後對應遊戲的情況，而電壓好像是一樣的；
2.在下會選擇購買 - 日版，因為慣例顯示，日版game的數量和種類都較美版多；
3.理論上，美/日版主機跟機的火牛只符合當地使用，所以canada的插座及電壓相符才可用，否則便要加adapter或火牛了。

1. As far as I know, the games are regionally locked, so that means US version consoles can only play US version games, while on the other hand, Japan version game will only be compatible with Japanese consoles. The menu language will be different of course.

2. Depends on how well you can read Japanese, for some of the games such as zelda, you cannot even play if you cannot read the japanese instructions (or hints); and you might have difficulty to use the menus if you do not know japanese at all. However, I have to admit that there will be more cool games coming up in the future, which you won't find in N. America at all.

3. Japanese electronics have the same voltage as in N. America, I have bought Japanese consoles in Japan and use in Canada, I am sure you do not need an adapter.

Myself I have already got a US version, I will buy a Japanese version next year in Japan. Make sure check out both nintendo sites of US and Japan:

http://www.nintendo.co.jp/wii/index.html (Japan)
http://www.nintendo.com/gamelist?sf=Wii (US)

for their available games (now and upcoming), so that you can compare and see which one suits you better.

Good luck!
