thin cedar or cypress shingle
A thin wooden shingle (4.5–6 mm thick) traditionally used for roofing temples, shrines, and other traditional structures. Domain-specific architectural term.
The roof of this temple is covered with thin wooden shingles.
Compound of 木賊 (とくさ, 'scouring rush' or 'horsetail') and 板 (いた, 'board'). The name likely derives from the resemblance of the thin, evenly cut shingles to the plant's stems, though the exact origin is uncertain.
