Not quite understanding your question here, but i mean extracting the game should be done using Winrar (install it for free from play store). It can handle japanese encoding and that usually helps with issues like this.
I recall having similar problems at some point using Joiplay and extracting it using different app helped.
Also, where are you getting game and how are you installing it anyway? Maybe its problem with game version you have and nothing wrong with what you are doing?
