ありが島: An Unmanned Island With a Thank-You in Its Name
A Japanese site introducing fishing trips and team experiences on Katashima, an uninhabited island in Japan’s Seto Inland Sea.
Field notes
ありが島 refers to Katashima, an uninhabited island in Suo-Oshima, Yamaguchi Prefecture. The site does not present a fixed attraction schedule: plans are built around group purpose, numbers, sea conditions, boat arrangements, equipment, and safety. It identifies fishing and team challenges as the two main possibilities, while noting that costs, access points, dates, insurance, and even feasibility require individual confirmation. The name reportedly comes from “arigatou,” or “thank you,” following a 2013 acquisition attributed to Kuniaki Shimizu.
