You can’t use the search function here, it doesn’t work. You have to use google and search the site instead.
I do remember reading where people did do that as well as other games, but realize that you can’t read most of Japanese until you learn most of the Jouyou Kanji. Otherwise you will constantly be looking up Kanji, let alone basic vocab.
Actually if you set the language to Japanese in the most recent Pokemon games, there’s an option in the settings that allows you to switch to kana instead of kanji, which isn’t perfect either, furigana would be better, but you could theoretically read Pokemon without knowing all the Jouyou kanji.
What’s better is that you can set the language to Japanese in all versions of the game, even if you buy it outside of Japan.
