The Japan Coast Guard (Japanese: 海上保安庁, Hepburn: Kaijō Hoan-chō) is the coast guard responsible for the protection of the coastline of Japan under the oversight of the Ministry of Land, Infrastructure, Transport and Tourism. It consists of about 13,700 personnel. The Japan Coast Guard was founded in 1948 as the Maritime Safety Agency and received its current English name in 2000.
The motto of the Japan Coast Guard is "Righteous Benevolence" (正義仁愛, Seigi Jin'ai).
Japan is an island country of 14,125 islands, of which approximately 260 are inhabited. Japan is the third-largest island country in the world, behind Indonesia and Madagascar. Japan is also the second-most-populous island country in the world, only behind Indonesia.
According to a survey conducted by the Japan Coast Guard in 1987, the number of islands in Japan was 6,852. At that time, the survey only counted islands with coastlines of 100 meters or more that were shown on paper maps.On February 28, 2023, the Geospatial Information Authority of Japan announced that the number of islands had been updated to 14,125 through a recount using digital maps. Since there is no international standard for counting islands, only islands with a coastline of 100 meters or more were counted, as in the past. According to the GSI, advances in surveying technology and the detailed representation of topographic features through digital mapping contributed to this announcement.
The Nanpō Islands (南方諸島, Nanpō Shotō) is a collective term for the groups of islands that are located to the south of the Japanese archipelago. They extend from the Izu Peninsula west of Tokyo Bay southward for about 1,200 km (750 mi), to within 500 km (310 mi) of the Mariana Islands. The Nanpō Islands are all administered by Tokyo Metropolis.
The Hydrographic and Oceanographic Department of the Japan Coast Guard defines the Nanpō Shotō as follows:
The Amami Islands (Japanese: 奄美群島, Hepburn: Amami-guntō) are a Japanese archipelago in the Satsunan Islands, which is part of the Ryukyu Islands, and is southwest of Kyushu. Administratively, the group belongs to Kagoshima Prefecture, Japan. The Geospatial Information Authority of Japan and the Japan Coast Guard agreed on February 15, 2010, to use the name of Amami-guntō (奄美群島) for the Amami Islands. Prior to that, Amami-shotō (奄美諸島) was also used. The name of Amami is probably cognate with Amamikyu (阿摩美久), the goddess of creation in the Ryukyuan creation myth.
The Ministry of Land, Infrastructure, Transport and Tourism (国土交通省, Kokudo-kōtsū-shō; lit. 'Ministry of Land and Transport'; MLIT) is a ministry of the Japanese government. It is responsible for one-third of all the laws and orders in Japan and is the largest Japanese ministry in terms of employees, as well as the second-largest executive agency of the Japanese government after the Ministry of Defense. The ministry oversees four external agencies including the Japan Coast Guard, the Japan Meteorological Agency and the Japan Tourism Agency.
