PARTIAL HISTORY


On October 13, 1942 departed Shortland Harbor bound for Guadalcanal to deliver 2nd Division soliders then return. The convoy included Sado Maru, Azumasan Maru, Kyushu Maru, Nankai Maru, Sakito Maru and Sasako Maru, escorted by destroyers Shigure and Akizuki.

Kyūsyū Maru beached near the mouth of Ruinin Creek near Ruaniu at Bunani Point on the north coast of
Guadalcanal.

Sinking History
On October 15, 1942 one of three transports sunk by SBD Dauntless dive bombers when a bomb hit ammunition in the rear hold, causing the ship to sink rapidly from the stern.
Also beached and sunk was Sasako Maru and Azumasan Maru.

Shipwreck
The Kyūsyū Maru beached near the mouth of Ruinin Creek near Ruaniu at Bunani Point on the north coast of
Guadalcanal. After American forces liberated this area, this shipwreck with the bow sticking up in the air was often photographed by American personnel.

This shipwreck is known locally as "Ruinin Wreck". During the 1960s, the upper surfaces of the ship were cut off and salvaged for scrap metal. During earthquakes, the shipwreck settled into deeper water.

In the late 1990s, some planks of metal from the ship remain piled high on the beach and lying along the waters edge.
Heavily damaged by bombing and scrapping, the ship is twisted from bomb damage. Over the years, divers have reported artillery shells still in their original packing and more notably the carbonized remnants of biscuits with the baker's name still readable. Rice bowls and the remains of uniforms can be seen in the better-preserved deeper sections of the shipwreck.

Today, the shipwreck is located 65' / 20m from shore. The bow is at a depth of 16' / 5m with the stern at a depth of 151' / 46m.
