Japanese Mastodon users are excited about the project above and beyond even organizing an offline event

Discussions will seemingly be technical stuff.
@Tezcatlipoca Yes, I think so. At least some tech medias talking about it and sponsoring the event. Also there are couple of hosting companies donating to help running Mastodon instance. I'm sure there are other examples though.
This was 7 years too late for me though.
@agektmr Cool! Very interesting too. It seems Japanese are excited about Mastodon from a conceptual and technical perspective, and maybe even in the philosophical goals. But somehow there also seems to be a much higher amount and higher acceptance of early commercial/institutional participation compared to here so far. Is this right?
