One of the Izu Shoto islands and only a couple hundred km from Tokyo Kozushima is much larger than some of it's neighbours but with only 1900 people and rising towards a scarred and barren volcano it feels remote and dominated both by geology and the ocean that surrounds it.
I camped there for a couple days and found virtually deserted hamlets filled with one eyed cats, incredible sashimi and two rival supermarkets competing for the limited business.
Interesting place to visit.
