This is why I think we 3ds owners over here in the west should have Japanese Symbols. It makes communication with Japanese players difficult, given that The east *Japan* have English. Come on Nintendo....
Japanese SmileBASIC users above junior high school can understand light English words like "key". When you ask them "key?", they will understand that you will request them to give you key of the game they have made. However, if their games are unfinished or they cannot give you keys because of copyright issues, few of them can explain so.
