Did you have Japanese or Gaijin instructors? If you didn't have Japanese, make sure someone explains how to "play the game" to make sure you don't do something wrong that could be misinterpreted as insulting.
When they are telling you how bad you did, just say "I understand" or "next time I will do better". Don't, at any time, argue with them.
There should be no surprises on the checkride. It is as scripted as it can be.
