No language, the font itself used to be called Japanese until one of the translators called it out and it resulted in it being changed to Asian with the new addition of the (International) font

In actual japanese this is all gibberish as the writing system doesn’t even work like this, but I assume this is just all random symbols of kanji that don’t really mean anything when put together

While there are some japanese fonts out there that are slightly more accurate with actual kanji and hiragana for individual letters, I assume Ralph just picked the first one he could find from google searching “Japanese font”
