Development
From the lessons learned from the 1991 dispatch of the Self-Defense Forces to the Persian Gulf, the Maritime Self-Defense Force took the example of the Royal Navy's Sandown class minehunter, built after the 1994 plan, especially in order to improve its capabilities regarding mine clearance. However, while the Sandown class is basically a minesweeper that does not have minesweeping ability. The waters around Japan have many muddy seabeds that are not suitable for minesweeping, and abandonment of minesweeping ability is unacceptable. For this reason, the class is also given the ability to sweep with Australian-made DYAD-sensitive minesweepers, but due to magnetic management issues, it was decided that it would not be installed all the time but would be received from the mother ship at sea as needed. Operational restrictions were large, and mobility was also restricted. [2] [3]
For this reason, it was built as a new type of minesweeper equipped with a domestic system that has the same performance as the overseas-made minesweeping system equipped in the Sugashima class, as well as realizing the installation of minesweepers on its own boat. [2]
The Japan Maritime Self-Defense Force, abbreviated JMSDF, also simply known as the Japanese Navy, is the maritime warfare branch of the Japan Self-Defense Forces, tasked with the naval defense of Japan. The JMSDF was formed following the dissolution of the Imperial Japanese Navy (IJN) after World War II. The JMSDF has a fleet of 154 ships, 346 aircraft and 50,800 personnel.
The Yaeyama class is the largest class of Japan Maritime Self-Defense Force minesweepers, designed for open-sea mine clearance operations. Three ships were built in the class, a further three ships were planned but were cancelled. The ships use wooden hulls to reduce their magnetic signature and is one of the largest-sized wooden hull ships designed today.
The Ariake-class destroyer is a class of destroyers of the Japan Maritime Self-Defense Force. Two ships of the Fletcher class were lent by the United States Navy and were in commission from 1959 until 1974.
JDS Hayase (MST-462) was a minesweeper for the Japan Maritime Self-Defense Force.
OPS-14 is a two-dimensional radar manufactured by Mitsubishi Electric. It is mainly mounted on the Maritime Self-Defense Force's self-defense ship as an anti-aircraft search radar. Variations include OPS-14B and OPS-14C.
OPS-9 is a two-dimensional radar manufactured by Fujitsu. It is installed as an anti-water search radar on the Maritime Self-Defense Force's escort ship. Variations include OPS-9B and OPS-9C.
OPS-4 is a two-dimensional radar manufactured by Oki Electric Industry. It was installed as surface-search radar on the Maritime Self-Defense Force's self-defense ship.
The Futami class was a class of oceanographic research ship of Japan Maritime Self-Defense Force (JMSDF) in the late 1970s.
JDSAkashi(AGS-5101) was an oceanographic research ship of Japan Maritime Self-Defense Force (JMSDF) in the late 1960s.
JDSSōya(MMC-951) was an minelayer of Japan Maritime Self-Defense Force (JMSDF) in the early 1970s.
The Mine Warfare Force belonged to the minesweeping force for the self-defense fleet of the Maritime Self-Defense Forces. Its main task is to lay naval mines in the event of an emergency, and it also helps to dispose of mines installed during World War II.
JSAwaji(MSO-304) is the lead ship of the Awaji-class minesweeper of Japan Maritime Self-Defense Force (JMSDF).

The Safety Security Force, also known as the Coastal Security Force, was an organization under the jurisdiction of the National Safety Agency, and existed from 1 August 1952 to 30 June 1954 in Japan. It was a maritime security agency established for the purpose of territorial waters security. It was the successor to the Maritime Safety Agency and the predecessor of the Maritime Self-Defense Force.
