thin wooden shingles
Thin, often scale-like wooden shingles used in traditional Japanese roofing, especially for こけら葺き (kokerabuki).
See also: こけら葺き
この寺の屋根はこけら板で葺かれている。
The roof of this temple is covered with thin wooden shingles.
こけら葺き is the roofing technique using こけら板; こけら板 refers to the shingles themselves.
こけら (杮) originally meant 'wood chip' or 'thin piece of wood', and 板 means 'board'. The compound refers to thin wooden shingles. The kanji 杮 is rare and often replaced by kana or ateji.
