5 May 1942:
Hiroshima. TAIYO MARU departs Ujina for Moji with 2,450 tons of materiel including ammunition, hand-grenades, illumination rounds and 150 tons of calcium carbide. The huge ship also carries 34 soldiers and 1,010 civilians. The civilians include military governors, doctors, bureaucracy staff, educators and technicians needed to administer conquered Southeast Asian regions.
TAIYO MARU carries a large number of oil field technicians bound for the petroleum production area of Palembang, Sumatra and to revive oil refining facilities at Miri and Balikpapan, Borneo. She also carries technicians bound for Malaya and for Java to install new equipment in the aluminum refinery facility and to construct a cement factory at Davao, Philippines.

At 1200, TAIYO MARU departs Mutsure for Singapore in convoy No. 109 also consisting of passenger-cargo YOSHINO MARU and cargo ships MIKAGE, DOVER and RYUSEI MARUs escorted by auxiliary gunboat PEKING MARU.
The five ships sail in a single row with TAIYO MARU leading. Due to lack of adequate organization, TAIYO MARU, which still could easily make 14 knots, is organized into a mere nine knot convoy.While steaming westward through the Genkai Sea, the convoy encounters a severe northeastern gale which further reduces speed.
8 May 1942:
At 1100, while patrolling in the vicinity, destroyer MINEKAZE and auxiliary gunboat TOMITSU MARU join the convoy as additional escorts.
At 1700, MINEKAZE and TOMITSU MARU terminate escort duty and peel off from the convoy. At 1900, PEKING MARU signals “danger of enemy sub appearance, use strict caution, prepare for gun action”. TAIYO MARU´s crew and gunners immediately man their battle stations. The passengers are informed of the situation. At this time, most of them have assembled for their evening meal.
170 km SW of Me-Shima, Nannyo-Gunto, Nagasaki Prefecture, SW Kyushu. At 1945, LtCdr Willis A. Lent’s (USNA ‘25) USS USS GRENADIER (SS-210) fires four torpedoes at TAIYO MARU. Two torpedoes pass under TAIYO MARU without exploding, but the other two hit her portside in the stern and No. 2 hold. The calcium carbide loaded in No. 2 hold catches fire and the exploding fumes blow away the hatch cover. Flames reach the stored hand-grenades and illumination rounds which go off and cause great damage to the ship´s bottom. The forward part of the ship immediately turns into a sea of flames. Communication with the foreship is cut off. Chaos breaks out and the passengers rush to the 18 life-boats only to find many of the boats blown away.
By 2020, sea water reaches C deck and the huge ship develops a 35 degree list to portside. About this time, all hands are ordered to abandon ship. Captain Harada Keisuke and about a dozen men chose to stay on board to go down with the ship. By 2035, the ship is restored to an even level, but starts to submerge rapidly bow first.
205 degrees and 80 nautical miles from Me-Shima Lighthouse. At 2040, TAIYO MARU rises vertically and disappears beneath the waves. Captain Harada and 156 of his 263-man crew, 656 of 1,044 passengers and four of 53 armed guards/gunners are KIA (total 817).
PEKING MARU sends a distress call , picks up 15 survivors and counter-attacks and drops a string of depth charges, but without effect on GRENADIER.
After receiving PEKING MARU´s distress call, MINEKAZE and TOMITSU MARU rush to the scene of disaster. Both ships arrive about midnight and start rescue work. Their crews perform outstanding service and despite terrible weather conditions pick up 480 survivors. The survivors are landed at Nagasaki at noon, 10 May 1942.
A large-scale search for other survivors by several fishing boats results in finding TAIYO MARU´s capsized No. 4 life-boat washed ashore on Me-Shima. Later, it is learned that the 48 occupants of this boat were rescued by small fishing vessel GENSHIN MARU No. 1 and landed at Nagasaki on 11 May 1942. No more survivors are found. Official total count for survivors is 543.
 Lt Matsuo is later KIA in the midget submarine attack on Sydney, Australia.
P> At the time of her sinking, TAIYO MARU had not yet been taken over by the civilian administration (Sempaku Uneikai).
