Have you ever considered where you will live after retirement? You do not have to work, so you can choose your favourite place anywhere.
During the pandemic, I have considered it once seriously. Found one very small village ( not more than 100 houses in the area) in Niigata-ken. The community officially gave me one day of experience in the village. There were clear pros and cons. This is from my personal view and it is on just one example.
1. Communications;
People who live in the district are like one big family. They support each other pretty closely and often have parties or festivals. Sustains life environment which by themselves.
Removing snow- blocks from the roof. Cooking Omochi (おもち）every end of the year. Summer dance party（盆踊り）. Cleaning roads in common areas like a mountain or a valley. Helping rice garden (plant and crop). Maybe, there are more.
You won't be isolated, but on the other hand, no attendance could destroy the communication between you and others.
2. Limited resources;
It is highly likely one supermarket in a long distance. That's it. Or Less. You must have a car.
Ama?on would help you a lot.
When you have to get to hospitals or clinics, it will take a whole day. (have to drive to the city centre)
3. Wild natural environment;
Stunning views and clean air. Wild animals are cute and sometimes funny. Bears, deer, racoons, and wild boars crossing roads.
Streetlights are often very few, and you may feel it is spooky at night. Or, do you like camping? You will love it! It is absolutely quiet and pitch black darkness nights. You can get firewoods as much as you want.
My back home in Hyogo- ken? Well, I think, scrap it once and a new small house would be great, if it is possible. Or, selling it and buying a cosy flat is also a great idea. I am not sure yet. If the future husband has a house, I will just move in.
