Ryoai rice terrace was selected as one of Japan’s 100 Fine Rice Terraces in 1999. The total agricultural land with an area of 4 ha consists of 120 pieces of rice terraces. These terraces spread on the steep slopes on the both banks of the Takisada River, which is one of the feeder streams of the Amari River and runs between the villages of Takisada and Kobira in the southeast part of Amari Valley in the southern part of Innai-cho, Usa City, Oita Pref. As the paddies are built on a narrow strip of land and the slope is very steep, terraces are retained with stonework. As it is really painstaking to work on a rice terrace, both villages are facing the problems of depopulation and ageing. The villagers are still practicing the traditional farming method of Kakeboshi (method of drying rice stalks to harvest the grain) and unite efforts to preserve this excellent landscape. The stone-made Ryoai Bridge over the Takisada River provides a nostalgic scene. A lot of tourists and photo manias visit this rice terrace during the rice-planting or harvest seasons.
