noun
Acanthopanax sciadophylloides; a species of flowering plant related to aralias
A deciduous tree native to Japan, known for its young edible shoots (taranoki-like). The name literally means 'filtered-oil tree'.
コシアブラノキの新芽は山菜として人気がある。
The young shoots of Acanthopanax sciadophylloides are popular as a wild vegetable.
この森にはコシアブラノキがたくさん生えている。
Many Acanthopanax sciadophylloides trees grow in this forest.
Both are trees with edible young shoots, but タラノキ (Aralia elata) is more commonly known for its shoots (taranome). コシアブラノキ is a different species with similar uses.
The name 漉油の木 (filtered-oil tree) likely comes from the historical use of its resin or sap for filtering oil, but the exact derivation is uncertain.
