History
Higashikata Village was established on April 1, 1908. It became the town of Koniya on April 1, 1936. As with all of the Amami Islands, the village came under the administration of the United States from July 1, 1946 to December 25, 1953. On September 1, 1956 Koniya merged with three neighboring villages to form the town of Setouchi.
Economy
The town economy is primarily based on agriculture, with sugar cane and citrus horticulture as the main crops. Industries include shochu refining and commercial fishing.
