Kaimei Maru was a Japanese troop transport ship operated by the Imperial Japanese Army during World War II which was sunk off Honshu on 4 September 1942 by the American submarine missing name. The ship was a British WWI Type B military cargo ship built by the Hong Kong and Whampoa Dock Company.
Construction and commissioning
Kaimei Maru, then known as British ship War Bomber was ordered by London's Shipping Controller[2] and was built at the Hong Kong and Whampoa Dock. It was launched in Hong Kong on 1 August 1919 from Yard No. 563.[3] War Bomber was configured as a British WWI Type B Standard cargo ship although its specifications were larger in scale than standard for ships of this class.[1] Indeed, War Bomber was the largest ship built to date at any Hong Kong dockyard with a length of 400 feet (120 m), a width of 52 feet (16 m) and a depth of 31 feet (9.4 m).[3] War Bomber displaced 5,226 tons[2] with a record deadweight tonnage of 8,000 tons.[3] The launch was attended by Sir Catchick Paul Chater, then Director of the Hong Kong and Whampoa Dock Company and by Sir Claud Severn, the acting Governor of Hong Kong.[3] Later in October 1919, the Hong Kong and Whampoa Dock Company would also launch War Bomber's sister ship, War Trooper.[3]
Belgian service
During the vessel's tenure as a Belgian ship, she was called Pioneer. Pioneer was purchased by Lloyd Royal Belge (de) of Antwerp where she continued service for a decade until she was transferred to Compagnie Maritime Belge, also of Antwerp, which had acquired Belgian shipowner Lloyd Royal Belge in 1930. Pioneer continued her Belgian service for another decade before being sold to Panamanian shipowner Agencia Maritima Carmar in 1939 where she was renamed as Carmar.[2]
Panamanian service
In 1939, Kaimei Maru, then known as Carmar, was purchased by the Agencia Maritima Carmar Ltda. of Panama. In 1941, Carmar was sold to Kaiyo Kisen K. K. of Kobe, Japan.[2]
Japanese service
On 13 November 1941, Kaimei Maru was requisitioned by the Imperial Japanese Army for service as a troop transport.[2]

During the invasion, Kaimei Maru was one of around 20 Japanese army transports ferrying roughly 7,000 troops under the command of Count Hisaichi Terauchi, Lt. General Masaharu Homma and Maj.

The invasion fleet was supported by elements of the Imperial Japanese Navy (IJN) including the IJN Southern Force under Vice Admiral Nobutake Kondō, IJN Philippines Invasion Group under Vice Admiral Ibō Takahashi and specialist forces of the Philippines Invasion Unit, 1st Base Force HQ under Rear Admiral Kyuji Kubo in command of missing name.[4][2]

The convoy was escorted by the destroyer missing name, missing name and minelayer missing name. The convoy arrived safely at the Taichow Islands on 30 January 1942.[2]
