Sasebo is in my neck of the woods , kinda ...I’m in Kumamoto . I am looking at mountains in Nagasaki Pref. out of my front window now .
Spent three years in Sasebo in the early 80s. My wife was a bus tour guide and so she and I would get in the car and see the fabulous places in Kyushu - Nagasaki, Unzen, Beppu, and Karatsu.
You’re a lucky man. Japan is a wonderful country.
