Japanese Bluesky isn't even close to Twitter yet. No politicians, no actors and actresses, no seiyuu, no utaite, a few mangaka and light novel authors, nobody that talks about trains, though there is the Frieren official account. There's a few Japanese that are just trying to generally meet new people or some that use Blueksy as a 1 way venting valve.

And as usual there are some political Japanese. In fact given how small Japanese Bluesky is the amount of politics is quite shocking given that Japanese tend not to be as vocal about politics on microblogging sites. (2ch on the other hand...)

Is the same algorithmic connectivity with Japanese happening on Bluesky as it is on Twitter, or are Bluesky's algorithms just as opaque as Twitter's?

But the en:ja ratio is like 5:1. Real population ratio between us:jp is like 3:1, and on Twitter it's more like 1.5:1 by active user count. This means Bluesky is less popular in Japan than it is in English speaking regions.
