Pseudosasa japonica, the arrow bamboo[2] or metake,[3] is a species of flowering plant in the grass family Poaceae, native to Japan and Korea.

This vigorous bamboo forms thickets up to 6 m (20 ft) tall with shiny leaves up to 25 cm (9.8 in) long.

[citation needed] This cold hardy bamboo species (tolerant to 0 °F/−17.7 °C) grows well both in shade and full sun.

Because it tends to be more shade tolerant than other bamboo species it is often used by gardeners as an understory to a tree-lined living fence.

[5] In cultivation in the UK this species has gained the Royal Horticultural Society's Award of Garden Merit.
