It has small scented yellow flowers borne in winter. The flowers are the inflorescences are 25cm or more long. They are first arching and then pendant. Dark or black fruits develop in spring and summer.

The foliage is pinnate, glossy dark green above, paler beneath. Each leaf usually has 6–8 pairs of leaflets together with a single terminal leaflet. The plant will produce new shoots regularly from the base, so that it is clothed in foliage at all levels.

It is typically up to 2 metres high and wide when mature. The plant is much grown as an ornamental shrub, and for use in landscapes. It is of value for its bold foliage, flowers and flowering season, and as a ground cover landscape shrub. It is a parent of some widely used garden hybrids, such as Mahonia media.

Despite the name, it is not native to Japan though it has been known in cultivation there for centuries.
