As the GIA says, it truly is the Land of the Rising Fun. GBA sales numbers are in, and all is well.
GameSpot VG reports that Famitsu's GBA sales numbers are in, and they show the fledgling handheld breaking the one million mark in Japan. In about three weeks of availability, Famitsu has recorded 1,132,612 Game Boy Advance units being sold in Nintendo's home country. Note that Famitsu sales data is usually less than the actual statistics, because of the sampling method used.
