In an interesting turn of events, it would seem popular import site Play-Asia has listed an Asian version of Dokuro on their site. While this is to be expected, it would seem this version also includes English. Naturally this is great news for importers, but be warned that it costs an additional $10 dollars, which honestly doesn’t sound like much, but is 33% more than the Japanese version. Also there is no conformation that this version will include the cleaning cloth (pictured above) either, so the difference in value can be quite great.
Currently there is no word on if the Japanese version will include English, but considering Asia usually differs from Japan, it seems unlikely. In any case, this might be your only chance to understand this weird game, as no one is currently publishing it stateside.
