KOTOBUKI MARU departs Woosung, Yangtze River for Maizuru, escorted by minesweeper W-21, destroyer TSUBAKI and gunboat UJI.
Minesweeper W-21 leads followed by TSUBAKI. At 1545, W-21 strikes a magnetic mine 300° distant 1,500
meters from South-east Knoll Buoy (south-westward of Grass Island; bearing 108°, 11.55 miles distant from Woosung Lighthouse). Rudder failure, main engine and generator unusable, oil leakage from the fuel oil tank, afterpart storage compartment and mine magazine flooded.
At 1554, W-21 anchors, but at 1600, a fire breaks out on board W-21. By 1605, the fire is extinguished.
At 2000, two tugs come alongside both sides of W-21.
At 1745, TSUBAKI also strikes a magnetic mine in position bearing 95°, 5.8 nms distant from Woosung Lighthouse.
According to the captain of TSUBAKI damage is as follows: (1) Aft ammunition hold flooded, forward hold and depth charge
compartment flooding. (2) There are numerous cracks in various places in the bulkhead of No. 2 boiler room, but they are
being patched.(3) Steering engine, aft main engines and diesel generator, and sonar device are inoperative (4) One person
is missing and 30 slightly injured.(5) Barely able to navigate at slow speed and steering by hand. TSUBAKI anchors off
11 April 1945:
At 0615, towage of W-21 starts. Later this day arrives at Mitsubishi Konan (Kiangnan) Shipyard for repairs.
KOTOBUKI MARU, which returned to Woosung the day before with gunboat UJI, departs again escorted by UJI and old destroyer
HASU. At 1659, about 1 nm from Woosung breakwater, a magnetic mine explodes off KOTOBUKI MARU's No. 2 hold. It
loosens many rivets in No. 2 hold which ships some water.
Gunboat UJI sends the following two messages referring to KOTOBUKI MARU´s damage:
2130, 12 April 1945: “Estimate that emergency repairs for KOTOBUKI MARU will require two days.”
0900, 13 April 1945: “KOTOBUKI MARU is undergoing emergency repairs. Scheduled to be completed by the 16th.”
20 April 1945:
In the early morning, KOTOBUKI MARU escorted by gunboat UJI and destroyer HASU departs Woosung. Off the Yangtze River estuary
the three vessels meet kaibokan OKINAWA, DAITO, UKURU, CD-27 and CD-57 which are arriving from Ssu Chiao Shan.Surrounded by
seven escort vessels, KOTOBUKI MARU proceeds to Tsingtao.
22 April 1945:
KOTOBUKI MARU and her escorts are attacked by ten Consolidated B-24 "Liberators”, but they score
no hits. One bomber is damaged and later forced to ditch. The convoy arrives at Tsingtao, China the same day.
KOTOBUKI MARU stays at Tsingtao until 4 May.
4 May 1945:
At 0400, KOTOBUKI MARU departs Tsingtao escorted by gunboat UJI and kaibokan DAITO, UKURU, CD-27, CD-57, CD-63, CD-207.
NB: It is appears possible that KOTOBUKI MARU sailed together with convoy HOMO-04 consisting of unknown number of unidentified ships.
5 May 1945:
The convoy arrives at Shihtao (Shitau) Bay, east tip of Shantung Peninsula.
6 May 1945:
The convoy arrives at Taito Bay (Taedong-Man), W coast of Korea.
7 May 1945:
The convoy arrives at Hakusha-Suido (Paeksa-Sudo), W coast of Korea.

15 May 1945:
KOTOBUKI MARU departs Chinkai for Maizuru escorted by kaibokan CD-36, CD-55,

Removed from the Navy List.
13 June 1949:
The hulk is refloated and scrapping begins.
 The exact date that CONTE VERDE was renamed TEIKYO MARU is unknown, but it seems reasonable that it occured at the time
of her charter voyage exchanging diplomats at Lourenco Marques.
 The U.S. Department of State chartered Swedish liner M. S. GRIPSHOLM as an exchange and repatriation ship under
the auspices of the International Red Cross, from 1942 to 1946. In addition to Japanese nationals, she also carried German
nationals to exchange points where she picked up Americans and Canadians. GRIPSHOLM’s Swedish captain and crew made 12 round
trips and carried a total of 27,712 reptriates. Exchanges with the Japanese were made at neutral ports: Lourenco Marques in
Portuguese East Africa and Mormugoa, Portuguese India. Exchanges with the Germans took place at Stockholm, Sweden or Lisbon,
 The Japanese intended to convert CONTE VERDE into a small aircraft carrier or a troop ship. She was to be towed
to Japan in August 1944 for further repairs and reconstruction.
 Sources vary as to the date and place where KOTOBUKI MARU hit a mine.
 TSUBAKI later arrives at Kiangnan Shipyard, Shanghai for repairs. After temporary repairs TSUBAKI departs Shanghai
on 8 May 1945, escorting convoy SHIMO-04. The convoy makes a great detour and finally arrives at Yuya Bay, Yamaguchi
Prefecture, on 17 May 1945. TSUBAKI is detached on 16 May 1945 with orders to proceed to Kure to undergo full-scale repairs.
