Fukushima

Fukushima is a small island at the edge of nearby Nagasaki prefecture, to the south of us. At one point, there was an operation of some kind there -- possibly coal mining, although we didn't find the mine entrance -- now long since abandoned. Three hours of biking the back hills of southern Saga prefecture got us there, although the onset of summer had unleashed the undergrowth in such force that most of the complex was buried away from our eyes.
