The catch is that rural Japan is a a shithole rife with xenophobia, privacy violations, bullying, and problematic neighbors. And that's for ethnically Japanese people, so it's be way worse if you were actually a foreigner.
There's a reason why people in Japan try so hard to move away from rural areas into cities.
I read a while back, a testimony from someone who grew up in small town America and then moved into the city when they were older. They explained that there is a lot of indoctrination against "cityfolk" because it's largely used as a scapegoat. As city dwellers tend to be more progressive due to their heightened social stimulation, this leads a lot of small-towners to hate the idea of progress
