Places to Meet People in Japan

Where are places/things you do that the expectation is to be sociable? Specifically, I mean outside of nomikai/bars, language exchange events, dating apps, local sports clubs, and your family (if you have one). I know these are common places and most foreigners do this because that's what is normal on Western countries, but I'm more curious on how the Japanese people differ from this. Of course I know some Japanese do these specific things as well so I'm mostly gathering information outside of these common places. I intend to stay in Japan and have several job types I'm working on securing for stability. Thank you!
