In addition to making some code improvements for a better readability, I've also created a file for japanese themes, so you do not need to change them one by one. I also corrected some overscan in japanese themes and in Game and Watch. In Game and Watch the problem was the size of the font, because despite using comic.otf it was using the size applied in jap.ttf (0.028). In the case of Japanese themes, it was necessary to add 0.05 of linespacing to remove the overscan, since decreasing the font size the readability becomes compromised.
