Near the southern edge of Kyushu there is an uninhabited island to which one can walk provided the moon's positioning is correct. When we were there the zig zag pathway was halfway passable as seen in the photographs. The island is situated across from the first Japanese campground I have seen. The campsites are not very private and there were two motorhomes situated there. One of these had a license plate belonging to Fukushima, the area devastated by earthquake, tsunami and nuclear meltdown.
