Apparently, if you buy a Japanese Wii, you can still buy and play Wii U Karaoke. Foreign credit cards work fine.

Furigana over every kanji.

Here is a sample video:

Is that you singing in the video? Very nice!

Sexy outfit. This game would make pre-drink drinks really, really painful for the neighbours.

Much better singing than I could ever do.

For those of you who like karaoke, Ultrastar Deluxe is a free open source karaoke game for Windows, Linux and Mac.

It supports Japanese text for the lyrics, but I don't think it supports furigana unfortunately.

Quote:UltraStar Deluxe is a free OpenSource karaoke game for your PC. The gameplay experience is similar to that of commercial product SingStar™ by Sony Computer Entertainment, which is exclusively available for the Playstation®. Unlike SingStar™, however, UltraStar Deluxe allows users to create their own songs.
By publishing the sourcecode, we’ve enabled you to customize the game completly to your heart’s content, desires and particular needs.
Especially you are allowed to modify the product as you wish.

Create your own themes or download content from the community, such as plugins, free songs or code patches for extended features.

In party mode it allows up to twelve players to sing along to your favorite music in order to score points, depending on the pitch of the voice and the rhythm of singing.

For UltraStar Deluxe to work you do not even have to buy expensive DVDs with not so many songs you really like, instead just buy DRM free audio files or use your album/cd music you already own and stored on your personal computer.

Just try out. Completly free with more than 10.000+ songs already available.
