Japan Foremost Rush Grass Producer

Symbolic of Yatsushiro is the production of domestic rush grass. The area centered on Yatsushiro leads Japan in rush grass output, said to account for about 80 percent of the domestic share. Blessed with a mild climate and fertile soil, the Yatsushiro plain has long been an active center of rush grass cultivation. In early summer, lush green rush grass before harvest spreads across the fields, creating the idyllic rural scenery unique to Yatsushiro. In recent years, small goods and sundries made from rush grass are also produced, and the appeal of its fresh fragrance and natural material is being rediscovered. Yatsushiro is also known as a major producer of winter and spring tomatoes.
