The game is entirely in (middle school level) Japanese. No English, but no region encoding either. There's a Nintendo DS version of this same game, but the graphics are much smaller. The PSP edition is nice to look at. This is the MyCom BEST edition of 2011. An earlier version, also by Mainichi Communications, came out in 2008.
There's an iApp version, too, apparently. (9-13-19 refers to available board sizes.)
