I’ve been placed! Fujioka-shi is the city and Gunma-ken is the prefecture. If you search “藤岡市 – 群馬県” in google maps, it will show you where that is! I’m happy with the placement, although I’ll still have to deal with snow. The area seems pretty and mountainous, with lots of hot springs and skiing if I wanted to go, but milder climate at the same time. It is also close to Tokyo, and I’m placed in a city and not the inaka, so amenities wont be hard to come by. A few links:
