Ship History
Built by Kawaminami Kogyo K.K. at Zosensho shipyard in Nagasaki. Laid down December 3, 1937 as a 6,732-tons passenger/cargo ship for Kokusai Kisen K. K. Instead, purchased on the stock by Osaka Shosen Kaisha (OSK Line). Launched December 8, 1938. Completed July 31, 1939 and registered in Osaka. Lloyds of London number 34722. Known as Toa Maru No. 2 but also known as simply Toa Maru.

Her maiden voyage was from Kobe to West Africa. During the remainder of 1940 until June 1940 operated Osaka Shosen Kaisha on their west Africa voyages.

Wartime History
On August 18, 1941 requisitioned by the Imperial Japanese Navy (IJN) as a transport IIppan Choyosen and attached to the Yokosuka Naval District.

PARTIAL HISTORY

On January 15, 1942 renamed Toa Maru No 2 Go under Navy’s secret instruction No. 513 and attached to the Sasebo Naval District as an auxiliary transport (Otsu) based at Sasebo.

PARTIAL HISTORY

On January 22, 1943 during the evening, departed Rabaul on a supply run bound for Bougainville, Shortland, Kolombangara and Munda. Aboard were 107 soldiers, concrete, a single Type 95 Ha Go Tank, a motorcycle with side car, munitions and supplies. Escorted by torpedo boat Hiyodori, subchaser CH-23 and mine layer Kamome. After departing Rabaul, the convoy was spotted by a Allied coastwatcher on New Ireland and reported by radio to the Allies.

During January 29-30, 1943 escorted by F1M2 Pete from the 958 Kokutai based at Shortland Harbor plus a detachment of Ki-43-I Oscars from 11th Sentai from Munda Airfield. Mine layer Kamome was detached from escort duty.

Sinking History
On January 31, 1943 bound for Disappointment Cove (Vila Harbor) on Kolombangara Island.

Meanwhile, on Guadalcanal a force of twelve SBD Dauntless from VSMB-233 (VMSTB-142) escorted by eight F4F Wildcats from VMF-112 that departed from Henderson Field on Guadalcanal. After take off, two Wildcats aborted the mission due to mechanical problems.

In the aerial battle overhead, two F1M2 Petes, one Ki-43 Oscar, two SBD-4 Dauntless and two F4F-4 Wildcats including F4F-4 Wildcat 11983 piloted by SSgt James A. Feliton plus F4F "Impatient Virgin" 03520 piloted by 1st Lt. Jefferson J. DeBlanc who claimed five Japanese aircraft before being shot down himself and was later rescued. For this action, DeBlanc later earned the Medal of Honor (MOH).

During the attack, the SBD Dauntless dive bombers scored several near misses and Toa Maru No. 2 was hit on the port side by an aerial bomb that caused flooding in Hold No. 1 and Hold No. 2. Also the escorting F4F Wildcats made a strafing run on the vessel that caused fires. Aboard Toa Maru No. 2, one crew member and two soldiers were killed during the aerial attacks.

Afterwards, fires were raging on the deck and the no. 1, no. 2 and no. 3 cargo holds were partially flooded due to the bomb damage near the bow. By 10:50pm efforts to reduce flooding failed. The crew and passengers were ordered to abandon ship.

Abandoned, the damaged vessel drifted for three days. Solomon Islanders loyal to a coastwatcher boarded the abandoned vessel and removed the ship's log and other materials. Finally, the ship ran aground and sank into Kololuka Bay north of Ghizo Island. On April 1, 1943 officially removed from the Navy list.

Fates of the Crew
The surviving crew and soldiers aboard were rescued.

Shipwreck
The shipwreck rests on her starboard side on a sloping sandy bottom north of Ghizo Island.

During 1974, Australian salvage divers removed the engines, propellers, chains and other gear and sold them as scrap metal. To facilitate their salvage efforts, the divers cut several holes into the hull one near the bow and two others near the engine room.

Since 1985, Dive Gizo has been offering SCUBA dives on the wreck on a near daily basis. Toa Maru No. 2 remains one of the best preserved shipwrecks at SCUBA diving depths in the Solomon Islands. The shipwreck is ideal because it is able to be snorkeled from the surface and the depth is suitable for divers of many experience levels.

On April 2, 2007 an 8.1 magnitude earthquake and tsunami hit the Ghizo Island area. The wheelhouse the ship was previously in excellent condition. During the earthquake, the bridge area fell off. This exposed some layers of holds previously inaccessible.

On the foredeck is a coral-encrusted mounting for a deck gun, missing and presumed to have broken off in deeper water. Only one bomb appears to have hit the vessel, creating a dramatic hole on the port side. The superstructure has evidence of an intense fire aboard that was hot enough to melt glass.

Lashed to the deck between cargo hold no. 2 and cargo hold no. 3 is a single Type 95 Ha Go Tank and is lying on its side. Nearby is a motorcycle and sidecar, fallen against the mast and a truck.

The aft holds are in shambles. Deeper in the holds it appears that the fire caused no damage. A small storeroom contains signal lamps and a gas masks. Numerous artillery shells, clips of rifle bullets, and endless sake bottles littered the forward holds. There are still pots and pans in the galley.

Hold No. 1
Contains cement bags. Partially flooded due to the bomb damage near the bow. Forward is the bow and to the stern is a single derrick with boom arm and Hold no. 2.

Hold No. 2
Contains Tanks, steel girders, bottles and rifle ammunition in 5 round stripper clips. Partially flooded due to the bomb damage near the bow. Forward is a single derrick with boom arm and Hold No. 1 to the stern are two derricks with boom arms and Hold No. 3.

Hold No. 3
This hold is empty. Partially flooded due to the bomb damage near the bow. Forward is Hold No. 2 and two derricks with boom arms. To the stern is the bridge.

Hold No. 4
This hold is empty. Forward is the bridge and to the stern is Hold No. 5.

Hold No. 5
Contains timber beams and logs. Forward of the hold is two derricks with boom arms. Forward is Hold No. 4 and to the stern is Hold No. 6.

Hold No. 6
