The area of Maizuru has been inhabited since prehistoric times, and numerous traces of
Jomon and
Yayoi period settlements have been discovered by archaeologists. The Yura River valley in particular was densely populated, and many
kofun burial mounds have been found. The area became part of
Tango Province in the
Nara period. During the
Muromachi period, the
Isshiki clan ruled as
shugo of the province, but were replaced in the
Sengoku period with the
Hosokawa clan, who constructed
Tanabe Castle, whose nickname "Maizuru Castle" was later adopted as the name of the city. Following the
Battle of Sekigahara,
Tokugawa Ieyasu awarded the entire province of Tango to
Kyōgoku Takatomo, who established
Miyazu Domain. To ensure the succession of his line, Kyōgoku Takatomo gave 35,000
koku of his holdings to his third son, Kyōgoku Takamitsu, and established a cadet branch of the clan at
Tango-Tanabe Domain, based at Maizuru Castle. The Kyōgoku were replaced by a cadet branch of the
Makino clan, who ruled until the
Meiji restoration in 1871. The town of Maizuru was established with the creation of the modern municipalities system on April 1, 1889. The same year, the
Maizuru Naval District was created and the associated
Maizuru Naval Arsenal for ship basing, construction, and repair was created in 1901. In the
Russo-Japanese War, many warships were based there, due to its proximity to the
Sea of Japan. Maizuru was raised to city status on August 1, 1938. After the Second World War, Maizuru was a key port for returning Japanese servicemen and detainees from continental Asia for over 13 years. Today,
JMSDF Maizuru Naval Base is a key district headquarters for the
Japan Maritime Self-Defense Force. ==Government==
