Minamiuonuma Koshihikari, Special Cultivation is a Japanese short-grain white rice grown by Kuwabara Nōsan in the Ikazawa district of Minamiuonuma, Niigata Prefecture. The paddies lie about 300 meters above sea level and are irrigated with snowmelt in spring.

The Special Cultivation designation refers to how the rice is grown. The farm uses fish-based organic fertilizer, applies no synthetic fertilizers during the growing season, and uses 80% less pesticide than the local cultivation standard.

Once cooked, the grains are soft and slightly sticky, with a natural sweetness that becomes more pronounced as you chew. The rice can be served plain or shaped into onigiri, Japanese rice balls.
