Amanatsu (甘夏) or Kawano Natsu Daidai (カワノナツダイダイ (川野夏橙)) is a yellow citrus fruit, a cultivar that originated as a mutation of the Natsu Mikan (ナツミカン (夏みかん)) or Natsu Daidai (ナツダイダイ (夏橙)). It was discovered in 1935 in Tsukumi, Oita Prefecture, Japan. The original Natsu Mikan that served as the basis for Amanatsu was found in Yamaguchi Prefecture around 1700.
