Nintendo announced a new contest/campaign for Japanese Club Nintendo members during a Nintendo Direct yesterday.
Members who register one Wii U game will receive 24 free hours of Wii Joysound Karaoke U service. In addition to that, they’ll also be entered into a contest where they can win one year of free Karaoke service.
Previously registered Wii U games will be counted for entries. Registering for a Club Nintendo account will earn five entries into the contest.
There will be 1000 winners.
