Ardisia japonica

Ardisia japonica is a species of ''Ardisia'' native to eastern Asia, in eastern China, Japan and Korea.

It is a low-growing evergreen shrub 20–40 cm tall. The are opposite or in whorls, ovate, 4-7 cm long and 1.5-4 cm broad, with a sharply serrated margin and an acute apex. The flowers are 4–10 mm diameter, with five white to pale pink petals; they are produced in racemes in late spring. The fruit is a drupe 5-6 mm diameter, red maturing dark purple-black in early winter.

A number of cultivars have been selected for growing as ornamental plants, including 'Hakuokan' and 'Ito Fukurin' with leaves, 'Hinotsukasa', with pale cream-coloured leaves, and 'Matsu Shima' with pink stems and variegated leaves.

Large doses of the plant as medicine can be toxic to the kidneys.
