History
The area of the modern city of Kainan was within ancient Kii Province, and Yayoi pottery and Kofunburial mounds indicate settlement since prehistoric times. The area is part of the Kumano Kodo and was a relay point between the capital and the onsen area of Shirahama since ancient times. During the Sengoku period, the area was a battleground between the forces of Oda Nobunaga and the local Saika ikki, one of many Ikkō-ikki movements. During the Edo period, the area prospered under the rule of Kishū Domain which gave protection to the Kuroe neighborhood as a center for the production of Kishū lacquerware. The village of Kuroe was founded with the creation of the modern municipalities system on April 1, 1889 and was raised to town status on July 7, 1896. Kuroe merged with the neighboring towns of Utsumi and Hikata and the village of Ono to form the city of Kainan on May 1, 1934. Kainan expanded by annexing the villages of Tatsumi, Kamekawa, Kitanokami, Nakanokami, and Minaminokami on April 1, 1955. On April 1, 2005, Kainan merged with the village of Shimotsu.
