Rio de Janeiro Maru Wreck
Rio de Janeiro Maru
A former Japanese passenger-cargo liner on the South American route, later converted to a submarine supply ship, lying on its side with huge propellers and a coral-covered hull that is popular with divers
The Rio de Janeiro Maru was built in 1930 as a passenger-cargo liner for Osaka Shosen Kaisha's South American service. Requisitioned as a submarine supply ship during the war, it was sunk east of Uman Island in February 1944. Its roughly 140 m hull lies on its starboard side, with the upper side about 10–15 m below the surface and the deepest point about 35 m, so divers of different levels can find a suitable depth. The two massive stern propellers, deck guns, and sake bottles and shells in the holds are the main attractions, and soft coral covers the hull, with plenty of fish. Boats from Weno dive shops take about 45 minutes one way.
