I have a Japanese Account but it say that it doesn’t exist in my Japanese account. But, you need a Japanese account to download it? Please help.

The game is good. the graphics are pretty good too. for songs not too many but quite pleasant to hear. this game has some flaws. but it's a shame because this game is like a ghost town.  Almost no players at all. If you are the type of person who enjoys games with interacting with people then this game is not recommended for you. Because as far as I'm a player in the game it's not 100 player at all that still play this game. But the event in this game still work. And the advantage of having no players at all is that I can easily get top 50 in every event. And the resources in the game are also not too stingy so I think this game is still good to play.
