290 yen or 1.1 percent at 26,890 after the launch in Japan

Despite the Wii being released in Japan earlier this week, Nintendo's stock has taken a slight drop.

"Nintendo lost 290 yen or 1.1 percent at 26,890 after the launch here (in Japan) Saturday of its Wii next-generation game consoles, during which buyers snapped up all 400,000 that were put on the market," dealers said.

Nintendo's stock has seen a 91 per cent increase over the past year, so a 1 per cent drop is not really all that disastrous.

Nevertheless, these are happy times for Nintendo. They have seen impressive sales figures for both the DS lite and also the newly released Wii, which has sold 600,000 since November 19th in America and also 400,000 in just two days in the land of the rising sun.
