• It’s in bumfuck nowhere
• I don’t speak Japanese
• Building it up to a modern living standard will be expensive
• I’d have to move to Japan

Unsorted list of reasons why not from the top of my head

It’s not that bad

Looking on maps it’s in a rural area but not that rural. The house is situated on the outskirts of a town, basically

Local middle schools website says they had 185 students in 2020, that’s pretty good for rural Japan

About a 30m walk from the town/school. Train station there, bunch of cafes, konbini.

It’s not going to be living in Tokyo obviously but there are rural areas in Japan that are far worse, where the school is 7 kids that all share a classroom even though they’re mixed grade 2-9 because the district has 1 teacher

Bigger reason for me: that house is decrepit and Japan experiences more natural disasters than pretty much any other country. Like I’m not living in a crap shack when the next earthquake, typhoon, or tsunami inevitably hits

The language isn’t that hard though. プラス、それからもっと漫画を読めるよ。
