Unfortunately we don't have any MM that can read Japanese. If a game can be transferred through a web portal, then the MM can translate the pages in their browser. But if the MM has to access the game to conduct the transfer and there's only a JP version, they won't be able to read anything. If no one has claimed it by now, that means no one will be able to process it for you. Sorry.
