An evergreen shrub of the Rutaceae family. It is now widely cultivated throughout Japan, but was first developed in Yamaguchi Prefecture. It is said to have originated as a hybrid or was obtained by accidental seedling propagation. The trunk is about 3m tall, and white flowers bloom in early summer, with the fruit ripening the following spring. The fruit is large and flattened, with an easily peelable skin and consisting of 9-11 lobes. It is juicy but very sour, and can be eaten raw or made into marmalade or candied. Recently, less sour varieties have been developed by crossbreeding it with other citrus species.

ミカン科の常緑低木。現在日本の各地に広く栽培されるが,山口県で作出された。雑種起源とも,また偶発の実生により得られたともいわれている。幹は高さ約 3m,初夏に白色の花を開き,果実は翌春に熟する。果実は大きく平たい球形,果皮は容易にはがれ,9~11の室から成る。多汁であるが,酸味が強く,生食のほかマーマレードや砂糖漬などにする。最近はこれをもとに他の雑柑類との間で交配された酸味の少い品種がつくられている。
