If you speak Japanese and are looking for a more serious relationship I'd recommend Pairs instead.
It's a little expensive, but that does tend to ensure more thoughtful profiles / interactions.
I met two lovely individuals and had a couple good dates.
Yesterday someone said it was only available on the Japanese version of the google and apple stores. You will probably have to get a Japanese phone? Just use Tinder, its free and accomplishes the same thing.

Heres a link to the google store version. It might get you it.
