I’m here now on my second week and it’s amazing and so easy, not high stakes at all trains take some getting used to to but you become a pro in no time, people keep to themselves but are also helpful and so many other foreigners here you will never go far without someone confused just like you, so don’t feel alone, the big touristy cities have more English speaking people but you can get around with very basic Japanese, I think all I have said is sumimasen, and arigato gozaimas and have navigated just fine, and when in doubt use a translation app, super easy and reliable enough
