Rubus coreanus (also called Korean bramble or Korean black raspberry, Japanese トックリイチゴ, Rubus tokkura) is a species of raspberry native to Korea, Japan, and China. It produces edible berries (not true berries in the botanical sense) that are fermented into bokbunja ju, a Korean fruit wine (although the majority of fruit commercially grown for producing this drink are actually Rubus occidentalis, native to North America).
