The Nintendo Switch has sold an estimated 330,637 units in its first three days on sale in Japan.
That's according to Famitsu, which adds that The Legend of Zelda: Breath of the Wild sold an estimated 190,060 copies in the country. That figure is retail only and does not include downloads.
These early figures are from March 3 to March 5 -- the Switch's launch week and first three days on sale. (Expect Nintendo to release sales data of its own in the future.)
To put these hardware numbers into context, the Nintendo Wii U sold an estimated 308,570 units in its first two days on sale, with the Wii U's launch week being from December 8 to 9 December 2012. The Wii, however, sold around 371,936 units in its first two days on sale from 2 December 2006 during its debut launch week.
Both those earlier consoles went on sale in December, and the Switch put those numbers on the board, absent of any major holidays.
