After the US / EU release, Cosen today released the official Japanese version of the Block Drop U puzzle game for Nintendo Wii U in Japan. The game already available from 2014 but Japan got only today on June 29, 2016. You can buy it from the Nintendo eShop for only 300 Yen (with tax).
In the Block Drop U you have to lead a red block and you have to reach the goal in all stages. Of course as you are getting into deeper and deeper in the game each stages will be much harder and you have to face with several gimmicks.
