The Maizuru Naval Base (Japanese: 舞鶴基地, Hepburn: Maidzuru Kichi), also simply known as the JMSDF Maizuru Naval Base, is a group of ports and land facilities of the Japan Maritime Self-Defense Force (JMSDF), which are scattered in multiple districts of Maizuru City, Kansai region, and where the Maizuru District Force, etc. are located. It is not officially called a base, but it is used as a common name.

## Background[edit]

In the Meiji era strategy against Russia, the Japanese Navy had a long-cherished desire to establish a military base for the Navy on the Sea of Japan side, and in 1889, the bay mouth was narrow and suitable for defense. In 1901, a guardian office was set up in Maizuru by setting a white arrow in Maizuru Bay, which was a good terrain for a military port because the waves were quiet in the bay and many ships could berth. It is located at Maizuru Port (Maizuru East Port), which has been used as a military port since the opening of the Imperial Japanese Navy's Maizuru Naval District.

Before World War II, the Imperial Japanese Navy Maizuru Naval District was located, but in normal times no battleships were placed, and it was closed during the Washington Naval Treaty, so it was neglected in terms of operation compared to other guardian offices. Many relatively old ships were deployed before and after the war, but in recent years it has been reviewed as the most important base on the Sea of Japan side, and two missile boats and the Sea of Japan to prepare for the activities of North Korean-registered craft ships. Due to its strategic importance, two Aegis ships were also deployed in sequence. Recently, the adjacent large wave bunker facility has been expanded. It is being strengthened as the only base of the Maritime Self-Defense Force on the Sea of Japan side, with a vast defensive range from the border between Shimane and Yamaguchi prefectures to the border between Akita and Aomori prefectures.

The main port of the Maizuru District Force, which is in charge of most of the security on the Sea of Japan side, as well as the 3rd Escort Squadron of the 3rd Escort Flotilla, etc. are their home ports.

## History[edit]

The Maizuru Air Base (Japanese: 舞鶴航空基地, Hepburn: Maidzuru Kōkūkichi), also simply known as the JMSDF Maizuru Air Base, or JMSDF Maizuru Air Station, is the only air base on the Sea of Japan side of the Maritime Self-Defense Force, and the need to strengthen its defense system was called for in preparation for the darkening of North Korean craft ships. However, because there was no Maritime Self-Defense Force air base nearby, the aircraft of the escort vessels belonging to the 3rd escort group whose home port is Maizuru Port are flying from Tateyama Air Base (Chiba Prefecture) each time. It was pointed out that "Maizuru is a defective base".
