Cool! Now I figure out how switch sales will be in Japan when animal crossing and pokemon launch.

Famitsu has just reported its latest hardware sales figures from Japan. For the week of March 19, sales tracking data has Switch at another 52,000 units sold. Total sales are at 4,037,144 units.

Famitsu reports that with that figure, Switch has surpassed four million units sold in Japan. The milestone was reached 56 weeks into the system’s lifespan.

Switch is also on a similar pace as Wii. With Wii, the console sold over four million units by its 54th week.

Update:

The Nintendo Switch has sold over 4 million units in Japan.

As is it has surpassed lifetime sales of the Nintendo GameCube in the region (4.04m) next is the Nintendo 64 (5.54m)

Damn, excellent news, and this is without Pokemon or Animal Crossing as well. I figure those will push the system even more. Smash Bros may push the system forward as well. There is still plenty of room for growth for the system in Japan.

Man, when Pokemon, Animal Crossing, Fire Emblem, and 2D Mario hit the Switch...it's gonna be nuts.

Damn. Switch on fire in Japan and like others said, big hitters still coming

Congrats Switch!
It may end as the highest home console selling in Japan.

We need Pokémon.

Cannibalism.

Should pass PS4 by years end. Not that they are in direct competition or anything though.

Shit is going to get crazy when Pokemon releases. 4 million when Pokemon and dragon quest are coming god knows when and there hasn't been a word said about animal crossing or monster hunter

Amazing! If it gets another 50k then that would be AWESOME!
