Sou-Wes Yonaguni

Sou-Wes was founded over 20 years go to offer diving services for the island of Yonaguni and Hotel Irifune has been run as a family business for two generations. We are the only place on the island to offer all-in-one tourist services including standard and luxury accommodation with delicious local cuisine, glass-bottomed sightseeing boat trips to the underwater monument, charter fishing trips, cruises and, of course, diving at the underwater monument and hammerhead shark-watching at numerous other sites around the island.

Sou-Wes founder Kihachiro Aratake was the first person to discover the underwater monument at Yonaguni in 1986 and has devoted a lifetime to studying it and working with researchers from around the world to try and unlock the mystery surrounding its origins. Born and raised on the island, there is no one better placed to introduce visitors to the history and wildlife of this unique island.
