Carpinus japonica, the Japanese hornbeam, is a hornbeam endemic to Japan but cultivated elsewhere as an ornamental.[2]

It is a deciduous tree growing to 12–15 metres (39–49 ft) tall with leaves that are longer and darker than the European hornbeam (Carpinus betulus).[3] The leaves are dark, glossy and slender, with 20-24 pairs of parallel sunken veins; every third tooth is whisker-tipped. The prominent catkins are green turning to brown.[4][5]

This tree has gained the Royal Horticultural Society's Award of Garden Merit.[6]
