it wouldn't take long by train or even bus. Sasebo is way south on the island of Kyushu in the northwest. It is a good deepwater port where several ships usually tie-up. The weather is close to Florida's. It's not that far from Nagasaki. If I had a pick between the 2 bases, I'd go to Sasebo in a minute.Kyushu has a great selection of large and small cities and is more laid back then the main island. No matter where you end up, learn the language and you will have a much better time !!
