Kishu mikan is a small mandarin orange variety with fruits measuring 25-50 mm in diameter. It features thin, smooth orange skin that peels easily and seedless flesh in some cultivars. The fruit grows in 7-14 segments with imperceptibly thin membranes, offering a juicy, intensely sweet flavor (11-14 Brix) without significant acidity. Its compact size, loose peel, and candy-like taste make it particularly popular with children.
