Regarding Japan's less savory side, [Shogo on YouTube](https://www.youtube.com/c/LetsaskShogoYourJapanesefriendinKy...) seems to be fairly measured and insightful in his videos on "Japanese traditional culture, tips on traveling to Kyoto, and social problems in Japan". Though they're only one viewpoint so take it with appropriate caveats.
I'm absolutely no authority but I get the feeling that Japan is a great place to live if you fit into one of the traditional societal roles, but otherwise can be very alienating. Luckily for the gaijin amongst us, one of those roles is "polite tourist", so expect to be welcomed and treated very well. Just don't expect the same wonderful experiences to continue if you try to put down roots.
