Takasago Maru

Takasago Maru was a passenger-cargo liner of OSK Line which later transferred to the Imperial Japanese Navy as a hospital ship.

Construction and career
She was laid down on 9 June 1936 and launched on 1 December 1936 by Mitsubishi Heavy Industries in Nagasaki. She was commissioned on 28 April 1937 into the Mitsui OSK Line.

Throughout 1937 to 1941, she made trips to Kobe, Keelung and Moji.

On 12 November 1941, she was acquired by the Imperial Japanese Navy and converted to a hospital ship by Kure Naval Arsenal on 1 December. On 8 April 1942, she was mistakenly lightly damaged by USS Porpoise (SS-172) and again on 26 April by USS Pickerel (SS-177) in the Manipa Strait despite her clear designation as a hospital ship. On 14 June 1941, she carried 500 patients while being escorted by the cruiser JAPANESE CRUISER Nagara. On 15 June, Rear Admiral Matome Ugaki departed the battleship JAPANESE BATTLESHIP Yamato to pay a visit aboard Hikawa Maru and Takasago Maru. She was attacked by aircraft but no damage was sustained from it while anchored off Shortland on 1 November of the same year.

Takasago Maru was escorted by the destroyer JAPANESE DESTROYER Akebono as they arrived at Truk on 5 September 1943. On 18 December, she transferred medical supplies to the cruiser JAPANESE CRUISER Katori at Harujima. She departed Singapore on 28 February 1944 for Saigon. The supply ship JAPANESE SUPPLY SHIP Mamiya replenish with Takasago Maru on 17 April.

USS Pilotfish (SS-386) encountered Takasago Maru on 5 February 1945 and was let go as she was clearly marked as a hospital ship. On 19 March, she was anchored near the battleships JAPANESE BATTLESHIP Ise and JAPANESE BATTLESHIP Haruna during the attack on Kure and escaped the harbor undamaged. USS Murray (DD-576) conducted an onboard search for violations and contrabands but found her to be clear and let her continue to Wake Island on 2 July. Same thing happened again five days later on 7 July, when USS McDermut (DD-677) conducted a search. While she was in Maizuru on 25 July, planes from the aircraft carrier USS Yorktown (CV-10) attacked the harbor but with no hits on Takasago Maru. On 1 December, she was assigned to the Allied Repatriation Service at Kure.

Between 1947 and 1956, she made trips to evacuate Japanese prisoners of war in Siberia and Nakhodka. On 23 March 1956, she was sold to Namura Shipbuilding, K. K., Osaka for scrapping.
