About seven hectares hold 1,340 paddies, which are small because of the hilly terrain. The smallest is only half a square meter. Terraced rice fields, which make up about 8 percent of paddies in the country, are increasingly being left idle, due to low productivity. In Kiwacho, an ordinance for Maruyama Senmaida was established in 1994 to protect the town's agricultural legacy. Kiwacho invited sponsorships for paddies to help encourage development of the town.
