Kyoho grapes (巨峰葡萄, Kyohō budō; lit. 'giant mountain grape'") are the most planted grapes in the world by area. They are a variety of hybrid grape popular in East Asia. The fruits are blackish-purple, or almost black, with large seeds and juicy flesh with high sugar content and mild acidity. The variety was first produced by the Japanese viniculturist Yasushi Ohinoue in the 1930s and 1940s by crossing Ishiharawase and Centennial grape varieties (Vitis vinifera × Vitis labrusca).
