History

As with all of Kōchi Prefecture, the area of Tosa was part of ancient Tosa Province. During the Edo period, the area was part of the holdings of Tosa Domain ruled by the Yamauchi clan from their seat at Kōchi Castle. The village of Jizōji (地蔵寺村) was established within Tosa District, Kōchi and the village of Tai (田井村) was established within Nagaoka District, Kōchi with the creation of the modern municipalities system on October 1, 1889. The two villages merged on March 31, 1935 to form the village of Tosa, which was elevated to town status on April 1, 1970.

Government

Tosa has a mayor-council form of government with a directly elected mayor and a unicameral town council of ten members. Tosa, together with the other municipalities of Tosa District and Nagaoka District, contributes one member to the Kōchi Prefectural Assembly. In terms of national politics, the village is part of Kōchi 1st district of the lower house of the Diet of Japan.

Economy

Key industries in Tosa are the primary industries: agriculture, livestock, and forestry. Farming takes advantage of the geographical differences in elevation and the difference in temperature between day and night. There are terraced rice fields and rice is the main product, followed by livestock, dairy and vegetables. In particular, the rice terraces on the fertile south bank of the Jizoji River produce high-quality rice. Farmers who have acquired ISO 14001 certification refrain from using chemical fertilizers, and use fertilizers made at the Tosa Town Compost Center to grow rice and garden vegetables with reduced pesticides, and brand "Reihoku Hachisai".

Education

Tosa has one public elementary school and one public middle school operated by the town government. The town does not have a high school.
