The wreck has been colonised by temperate marine organisms including soft corals sponges and encrusting communities transforming the hull into an artificial reef. Japanese spider crabs greenlings and octopus shelter within the hull structure while schools of temperate fish patrol the water column above. The main deck sits at approximately twenty metres providing accessible exploration for divers without wreck speciality certification. The wreck's location in the nutrient-rich Izu waters ensures abundant marine colonisation and diverse species utilisation.
