The Nintendo 3DS is region locked. Back in January we told you about a rumor the 3DS would have region codes. A Nintendo support staff member sent out this email, “There are no Region codes in DS and DS Lite, but DSi, DSi [XL], and 3DS have region codes. The region codes are installed in each game and the 3DS itself. … You can’t play if the region codes are different." Nintendo never officially commented on the rumor but now that the 3DS is on American soil gamers are confirming their imported games don't work. In fact, the 3DS doesn't even acknowledge the software.
A writer at Destructoid tested out the rumor for himself. He tried to play a North American copy of Super Monkey Ball 3D in his Japanese 3DS, the game didn't even register in the menu. Imported DS games will still work in the 3DS though.
Japan gets more than a handful of games before we do in America. There's an even bigger handful of games that never make their way stateside. Gamers who previously would import games will now have to buy a Japanese 3DS to play.
