    Site Overview

    The Yomitan Wreck is a purpose-sunken vessel resting upright on a sandy bottom at thirty-two metres depth off the coast of Yomitan Village on Okinawa Main Island. The wreck has been colonised by an extraordinary diversity of coral and sponge life transforming it into an artificial reef that attracts an abundance of marine life including whitetip reef sharks barramundi cod and schooling jacks. The main hull structure is largely intact with several penetration points accessible to trained wreck divers including the engine room cargo holds and bridge area. The upper deck sits at approximately eighteen metres providing an accessible overview for divers without wreck speciality certification.
