I studied Japanese for two weeks on beginners level and I really enjoyed it. The teachers were all happy and seemed engaged in their teaching. Many students come and go every week but I still felt seen and valued just as much as anyone else. A good mix of students of all ages and from all over the world. On my two weeks I never felt bored or not engaged, it was all good fun. I would have wished for more conversation practice though. I also think they could have taken advantage of the fact that we're in Japan and made us talk to people in the city as homework perhaps. But perhaps you'd have gotten all this if you'd studied longer. In any case I really feel inspired to keep on studying Japanese now.
