The, was a six-hour naval confrontation between Japan and North Korea. It took place near the Japanese island of Amami Ōshima, in the East China Sea on 22 December 2001.
The encounter ended in the sinking of the North Korean vessel, which the Japanese authorities later announced was determined to have been a spy craft.[3] [4] The encounter took place outside Japanese territorial waters, but within the exclusive economic zone, an area extending from Japanese land, within which Japan can claim exclusive rights to fishing and mineral resources.
An unidentified ship was spotted in Japanese waters on 21 December 2001. The armed trawler was detected by a communications station in Kikaijima, Kagoshima, which was under control of the Japanese Defense Intelligence Headquarters.[5]
In 1999, another North Korean vessel encountered by the Japanese Coast Guard was claimed by Japan to have been a spy craft, though North Korea denied it.[6]
Early the following morning, the ship was chased by four Japanese Coast Guard vessels, who ordered it to halt, and fired 25 warning shots upon the ship when those orders were ignored.[7] A six-hour firefight ensued, in which over 1,000 machine gun rounds were fired by both sides;[8] the North Korean crew were said to have wielded shoulder-held rocket launchers.[9]
The North Korean trawler was meanwhile hit by a number of 20mm rounds.[10] [11] Several explosions not directly related to Japanese attacks rocked the ship before it was sunk. According to The Guardian, "fifteen survivors were seen clinging to a buoy in heavy seas, but the Japanese ships were ordered to ignore them because of fears that they would use force to resist capture".[10] Two bodies were recovered, thirteen more persons were declared missing and presumed dead several days later.[10]
The Special Boarding Unit was mobilized to board the ship, but did not do so as they had to wait for official orders from the Japanese Defense Agency. The ship sank before such orders arrived.[12]
In 2003 the trawler was raised by the Japanese to confirm its origin and intentions. Inspection of the hull determined it was of North Korean origin and most likely an infiltration and spy vessel. It was revealed that the vessel was camouflaged as a Chinese or Japanese fishing boat and that it could reach a speed of, far faster than any commercial trawler. The ship also contained a hidden double-hatch located in the stern to be used as an exit door for speedboats.
Once the inspections were completed, the hull was displayed at the Japanese Coast Guard Museum Yokohama in Yokohama, where the trawler became a popular tourist attraction.
