Can I change the region of my Wii U?

[gray hamlet]

Is there any way to change the region of the Wii U? I have a Japanese console, but I want to make it European.

I think it's possible to do so but it's very hard

I remember I saw someone ask the same question and someone answered it saying that it's better off getting a region free mod than go through all the trouble of something
