History
During the Edo period, the area was part of Shimōsa Province, and Mitsukaido village developed as a center for river transportation on the Kinugawa River. The town of Mitsukaidō was established within Toyoda District with the creation of the modern municipalities system on April 1, 1889. The area was transferred to Yūki District in 1894. On July 10, 1954 Mitsukaidō merged with the villages of Sugawara, Ohanawa, Mitsuma, Goka, Ono and Sakate, and was elevated to city status. It further annexed the villages of Sugao and Uchimoriya on April 1, 1956.
On January 1, 2006, Mitsukaidō absorbed the neighboring town of Ishige, Yūki District, Ibaraki and officially changed their name to Jōsō. The area suffered much damage from flooding of the Kinugawa River due to heavy rains in September 2015.
