Yes, you can get a DS Lite in Japan.

Stop paying those greedy online auction vendors extra money for a DS Lite. Nintendo's handheld game console is sold out in Japan, but you can buy the awesome cell phone strap version for only 150 yen. I actually prefer this non-working, miniature one. It comes in red, and it has a permanent picture of Mario on it. That pretty much does it for me. Get yours here
