Are there any active English/international social communities in Osaka?

I am a long-term resident looking for a way to rebuild social circles again in Osaka after being away for years. Make new friiends and maybe try dating.

I see a few people organizing bar nights and a few meetup groups. But is there a larger, more organized thing happening anywhere? A really big, active Discord server or FB pages. Any community organizations where people are really active in real life? Anything really helping people meet and build longer-term relationships here?

I was on JET years ago, but that community seems to have shrunk a lot. The social media sites I've seen are very quiet. I'd like to find a way to meet people beyond 'go to a bar and hang out'.

Thanks in advance for your help.
