The coexistence of Kanji and Hiragana is already the result of simplification. If you look at a Japanese document from the 1880s or whatever, it's almost all Kanji because every single word theoretically has a Kanji. At some point it was decided that it was too hard to teach everyone so many kanji so some words were allowed to be written in hiragana instead.

Less kanji being taught has also resulted in some very weird bullshit. For example, dermatologist is 皮膚科 (hi fu ka) but the middle Kanji appears not to be in common usage so often it'll be written as 皮フ科 with a katakana Fu instead.

So idk if you really want to ask Japan to simplify again, they kind of have a cursed monkey paw approach to it.
