I can only speak from being Japanese by blood and culture, but don't *live*(visiting is JPLT 4) in Japan unless you're at least JPLT 3 or close to. Japanese generally don't appreciate foreigners who make no effort to talk to them. If you must focus, focus on speaking since you can always ask what something means but no one is going to stand and wait for you to write a whole sentence in illegible kana. I would also look up the etiquette of trains, busses, etc. Especially Queing. So you can be a polite person and not annoy the people around you with loud talking or lots of luggage. Other than that, Japan is introvert paradise but can be a bit isolating if you are making friends at first. There's also the toxic work culture in Japan. Though it's gotten better, it will be a while for things to truly improve. If you need help with Japanese, I can help.
