avenue of cedars; cedar-lined road
Refers to a road or path lined with Japanese cedar (cryptomeria) trees. Often evokes a scenic, traditional landscape.
I walked along the avenue of cedars leading to the shrine.
Compound of 杉 (すぎ, 'cedar') + 並木 (なみき, 'row of trees, avenue'). The reading なみき is a rendaku form of 並 (なみ) + 木 (き).
