Mito (水戸市, Mito-shi) is the capital city of Ibaraki Prefecture, in the northern Kantō region of Japan. As of 1 July 2020, the city had an estimated population of 269,330 in 123,282 households and a population density of 1239 persons per km². The percentage of the population aged over 65 was 27.1%. The total area of the city is 217.32 square kilometres (83.91 sq mi).

Mito Station is about 10 km inland from the Pacific Ocean which Naka River, flowing from the north to the east of the city, pours into. Immediately south is Lake Senba, a recreational area. A main street extends from Mito Station to the west, and residential areas to the south and the west in particular.

The Yamato people settled in Mito around the 4th century CE. Around the end of the Heian period, Baba Sukemoto, a warlord of the Heike clan, moved to Mito and built a castle there. Mito Castle changed hands several times after that; coming under the control of the Satake clan won it in Sengoku period, but the Satake were forced to surrender it to Tokugawa Ieyasu in 1603 after the Battle of Sekigahara. Ieyasu's son Tokugawa Yorifusa was then given Mito Castle, becoming head of one of the three "gosanke" branches of the clan qualified to provide a new shōgun should the main family line fail. During this period, Mito was the seat of the so-called Mito School, a congregation of nativist scholars of Confucian persuasion led by Aizawa Seishisai, who during the 18th and 19th centuries advocated Western learning as a means not only to further Japanese technological development and international strength, but as means to prove Japanese uniqueness and superiority among nations. The Kōdōkan was the largest of the han schools. The capital of Edo was directly connected to Mito by the Mito Kaidō. The Tokugawa ruled Mito until the Meiji Restoration.

The city of Mito was formed on April 1, 1889 with the establishment of the modern municipalities system. It was one of the first 31 cities to be established in Japan. With a population of 25,000, it was designated as the prefectural capital of Ibaraki Prefecture. By 1900, the Jōban Line connected Mito to Tokyo, and by 1910, telephones and electric lighting were available throughout the city. More than three-quarters of the city was burned to the ground during the Mito air raid of August 2, 1945, just before the end of World War II.

The borders of Mito expanded in 1955 through 1958 through the annexation of the neighboring villages of Kamiono, Watari, Yoshida, Sakedo, Kawawada, Yanagawa, Kunita and Iitomi and Akatsuka. The village of Tsunezumi was annexed in 1992. In 2001, Mito was designated a special city with increased local autonomy. The neighboring town of Uchihara was annexed in 2005. The city suffered from severe damage in the 2011 Tōhoku earthquake and tsunami with 25,982 houses completely or partially destroyed; however, there were only two fatalities.

Mito was designated a core city with further increases in local autonomy on April 4, 2020. (CLICK HERE TO RETURN)
