As an #Asian myself, I'm happy to see that ideas, developers, and software from #Japan are going mainstream. There are a lot of things the West, and the world for that matter, can learn from Japan.
Not only from the Japanese, to be exact, even from #Korean made software. I talked about last year how #Korea created its own Internet culture that not even #Google and #Microsoft can compete with. (See: #Naver's amazing interconnected platforms; what Google would have been if they had a vision.)
Pleroma itself also have a lot of forks, though not as much as #Misskey and #Mastodon. One such is #Rebased.
You can give the Rebased fork a try over at https://c.wtf featuring the #Soapbox frontend. (#DidYouKnow that the Soapbox frontend originally started as a custom frontend for Mastodon?)
