Brawl is dethroned in Japan by the latest Mario adventure.
New Super Mario Bros. Wii has set the record for being the fastest-selling Wii title in Japan, according to a famitsu.com article, with 936,734 units sold in only four days. The previous first-week record was held by Super Smash Bros. Brawl, released in January 2008, which sold 816,000 units in its first week of release.
The game, which was released on December 3 in Japan, might have even topped its predecessor. New Super Mario Bros. for DS, released in May 2006, sold almost 900,000 copies in its first week according to tracking firm Media Create.
