underwater monument Sightseeing Boat
In 1986 Sou-Wes owner and dive master Kihachiro Aratake discovered what appeared to be the remains of a lost civilization under the seas surrounding the craggy and mysteriously beautiful island of Yonaguni. Having devoted a lifetime to the research of these undersea structures no one is better equipped to guide divers round the site and uncover the secrets of an ancient and long-lost civilization. We offer fun dives and trial dives to the site. Alternatively you can view the site from our glass-bottomed sightseeing boat that departs daily. Come and see this underwater Machu Picchu for yourself!.
Hammerhead shark-watching!

Yongunijima is one of the only places in the world where divers can see schools of hammerhead sharks on a daily basis. Our team of experienced divers will guide you to the best points around the island for shark-watching.
