The bank stuff has been going on for years. Surprised you haven't had this before. I've had the bank contact me when someone has deposited as little as 2,000 yen. Friends in Joetsu get 45 minute interviews at the local bank when a deposit comes in and they have lived there for 25+ years. Utterly anal retentive.The bank I can deal with because that is the government telling them that gaijin money launder. The reult being they do not want to accept you payment of your tradies bill who has an account at that branch.
Otherwise when I was there in April I didn't have any negative interactions with locals. Though fortunately I didn't have to brave the hell that is the Nagano immigration office.
