Check the translation of the android application

Hello.
The interface of small application should be translated from English to Japanese.
In fact it WAS translated, a freelance translator had translated the interface to Korean and Japanese. The Korean translation seems to be right, but I have serious doubts about the quality of Japanese version. All the interface (40 strings actually) is behind LJ-cut.
I just want someone to have a quick look and say - is this an acceptable translation or not.
