Heliboard was the closest to Gboard imo. It would be better though if it supports Japanese input.

I did not dropped reddit completely, occasionally going in there through google searches but ever since the api fiasco I’ve never visited the site directly. I still haven’t deleted my account but didn’t used it since then and is planning to delete it. Lemmy does not have a lot of content and the niche communities compared to reddit. That is not a bad thing though and instead it had stopped me from mindless scrolling I picked up from using reddit.
