What's your house budget? For a place with a man cave you'd probably need 250k here in southern Japan. While not really remote, it's far from the busy likes of Tokyo. All of my work is with companies around the globe in all sorts of time zones. I'd say it's boring for a single person out here, you'd definitely only put up with it if you had a family. Securing a visa would be another challenge unless you married a Japanese citizen, which you wouldn't want to do after coming here as divorce rates are high for mixed couples. Culture can be very frustrating too after a while.
