Kozushima is a remote island located about 180 km south of the Tokyo metropolitan area. Many tourists visit the island for stargazing as they have done a wonderful job preserving the night sky. In fact, in May and June of 2020 more than 400 street and road lights were replaced with dark sky friendly fixtures with the Dark Sky Park certification in mind. It changed the night scene in the village, creating a lighting environment that protects the natural environment and the night sky while ensuring the necessary brightness for the residents’ lives. The island can be reached in four hours by boat or 30 minutes by air from mainland Tokyo.
