noun
log on shrine roof set perpendicular to ridgepole
Architectural term for a decorative log placed horizontally across the ridge of a Shinto shrine roof, often in pairs. Also called 鰹木 (かつおぎ) because its shape resembles a dried bonito fillet.
神社の屋根には鰹木が並んでいる。
Katsuogi logs are lined up on the roof of the shrine.
鰹木は、棟木と直角に置かれる。
Katsuogi are placed perpendicular to the ridgepole.
The name 鰹木 (かつおぎ) likely comes from the resemblance of the log's shape to a dried bonito (鰹) fillet. The exact historical derivation is uncertain.
