Nintendo confirms region-lock for Wii U
Nope, Famitsu wasn’t crazy. The Wii U really will be region-locked.
Nintendo UK was able to confirm to Eurogamer that this is in fact the case. So if you have a US Wii U and wish to play a Japanese game, you’ll need a separate Japanese console to play it.

Furthermore, I think VGChartz should add a "Like"-button.
