The hafu are the triangular end panels or sections, including the gable end wall and barge boards, and any decorative plates on the gable wall surface. There are different names for various styles of hafu. Domed, bell-shaped gables are called kara-hafu (literally, Chinese cusped gable), while the triangular gables at the end of concave sloping roofs are called chidori-hafu because they resemble the downswept wings of a chidori (plover) bird in flight.
