According to Famitsu, the 2nd best selling game in Japan from 1/14/2008 to 1/20/2008 is "Mario and Sonics at the Olympic Games" with over 90,000 copies sold during that period.

Mario Party DS came in third. It is going strong and had sold 1.5 million copies already in Japan.

"Layton Kyouju to Akuma no Hako" came in 7th. I have a brief game guide here. There is a link to the web trial version of the game as well.

15 of the top 30 game sales spots belong to DS games while 6 belong to Wii games. 9 of the top 10 games belong to Nintendo platforms.
