Super Smash Bros. Brawl has been out for at least three days in Japan now. On its first day, 500,000 copies of Brawl were sold. It's a tremendous amount of copies sold on its first day, and Brawl was only sold in Japan. Well according to Japanese game site Mantan, 700,000 copies of Super Smash Bros. Brawl have been sold in three days! It was the Thursday launch through Sunday.

The Mantan Web columnist, Taketo Matsuo, an employee of Japan's Tsutaya media retailer, expects the game to top the million marks this week.

As the North American release date arrives, Brawl will continue to sell. Once it hits North America and other regions, the numbers will incredibly increase. I can truly say that Super Smash Bros. Brawl will be the best selling game on the Nintendo Wii.
