As far as I know, none of the files in the game folder have Korean text in their names, so staying on Japanese locale is completely fine. Since you are using the English translation, you shouldn't really have issues as long as you have the RTP installed.

To extract the files, you must use a file manager program called 7-zip. It's free.
