you can read my consipracy theory about it here:

The only reason this happened is because the wii u has no next gen competition in japan. So it was either get a wii u or get a ps3 or xbox

Here's the link to media create: http://www.m-create.com/ranking/

And here's a link to an English website that has translated media create numbers: http://gematsu.com/2013/12/media-create-sales-121613-122213

Yeah, that is possible. I hope Wii U post holiday sales will not largely decrease during PS4's launch.

Famitsu

Pokemon X / Y: 231.112 (3.820.346)

Animal Crossing: 44.691 (3.979.859)
even though AC has over 1mil digital sales lol

Good for us that the PS4 isn't out.

or maybe because of SM3DW and advertising the hell out of WiiU? Also ...

NINTENDOMINATION has returned:)

Wii U= Not doomed. GOOOO Wii U!!

wii U should sell around 250-300k WW, nice numbers overall.

It's actually not unusual for a Nintendo console to put up these numbers around this time of year, actually, GameCube did similar things. Nintendo always enjoys a very nice holiday gift giving boost in December in Japan:

With the exception of that dissapointing GameCube 2002 in Japan that's fairly consistent across the board. Guess the Japanese really don't like Zelda/Metroid (Wind Waker and Prime 1) versus Mario and Smash.
