Out of nowhere, a new WiiWare game showed up on Nintendo of Japan's WiiWare page. Yakuman Wii: Ide Yousuke no Kenjou Mahjongg (Ide Yousuke's Healthy Mahjongg) is a Nintendo-developed, multiplayer mahjongg game with Mii integration and online play. It also features hints from a Mii of Ide Yousuke (who is apparently a famous mahjongg player, and whose name appears in countless mahjongg game titles).
Even though we just found out about it, Nintendo plans to launch it in Japan next week, at a cost of 1,000 Wii Points. However, because it's a mahjongg game, we would be even more surprised to see it released elsewhere.
