There have been several Japanese factory whaling ships named
Nisshin Maru. After the U.S. Navy's Pacific Fleet was
attacked at Pearl Harbor on December 7, 1941, all Japanese factory ships soon began to serve in the war effort till sunk or till the end of
World War II in 1945. •
Nisshin Maru (16,764 grt), commissioned in 1936, was a whaling factory ship built by Taiyo Gyogyo from a purchased blueprint of the Norwegian factory ship
Sir James Clark Ross. This
Nisshin Maru was sunk by the submarine in
Balabac Strait, Borneo on May 16, 1944. •
Nisshin Maru No. 2 (17,579 grt) built by Taiyo Gyogyo, was commissioned in 1937 and was damaged on February 7, 1943, by two torpedoes fired from . General
Douglas MacArthur, as military governor of Japan in 1945, encouraged the now defeated Japan to continue whaling in order to provide a cheap source of meat to its starving people, and to supply millions of dollars in oil for the United States and Europe. The Japanese whaling industry quickly recovered as MacArthur authorized the commission of two converted
T2 tankers as whaling factory ships (
Hashidate Maru and
Nisshin Maru No. 1), to once again hunt whales in the Antarctic and elsewhere. It was sold in 1961 to Taiyo Gyogyo, fitted it and changed her name to
Nisshin Maru No. 3 (23,106 tons). ,it was still whaling as of 1980; when was it decommissioned?--> •
Nisshin Maru The latest
Nisshin Maru (8,030-tons) was built by Hitachi Zosen Corporation Innoshima Works and launched in 1987 as
Chikuzen Maru. It remains a whaler factory ship, but following the September 2018 Florianopolis Declaration by the IWC, Japan withdrew its IWC membership on December 26, 2018. The vessel is no longer contracted by the
Institute of Cetacean Research, and it resumed commercial hunting in Japan's territorial waters and
exclusive economic zone on July 1, 2019. A subsidy of 5.1 billion yen (US$47.31 million) was budgeted for commercial whaling in 2019, and was expected to hunt 227 minke whales by the end of 2019. == 2007 Antarctic voyage ==
