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.

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.

On 27 December 1977, a new Underwater Explosive Disposal Unit was added to the Maizuru Defense Force.

On July 1, 1987, the Maizuru Defense Force was abolished and reorganization of the guard took place.

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.

Therefore, the Maritime Self-Defense Force made a plan to develop a runway, control tower, hangar, etc.

In February 2002, dispatched to the Indian Ocean under the Anti-Terrorism Special Measures Law (patrol helicopter mounted on an escort ship).

In October 2004, dispatched a disaster to the flood damage of the Yura River caused by Typhoon Vicente in 2004.

SH-60J and others belonging to this base rescued passengers left behind on the roof of a submerged sightseeing bus.

Conducted damage situation reconnaissance and transportation of personnel and relief supplies.

On January 23, 2008, transport of emergency cases of burns from Maizuru to Kanazawa (Request for dispatch of disaster due to helicopter inability to fly).

On February 12, rescue of fallen people from fishing rafts in Maizuru Bay.

From 6 to 7 December, search for missing persons while surfing off Takahama, Fukui Prefecture.

On July 23, dispatched to a disaster in response to a rotorcraft distress in the Tajima region of Hyogo prefecture.
