Also called hafugashira, 破風頭, or hafu-no-ogami, 破風の拝. The joint between two bargeboards, hafu-ita 破風板 (see *hafu 破風). The joint used to connect the two parts of the bargeboard where they form a peak was relatively simple from the end of the 7th century to the 12th century. A rectangular piece was cut out of the top of one bargeboard and the same size cuts were made on each side of the top of the other bargeboard. The central, extended piece fit snugly into the cut-out on the peak of the other bargeboard. The two were secured by a wooden pin that penetrated from the exterior face to beyond the interior side. Example: Hōryūji *Kondō, 法隆寺金堂 (rebuilt 693), Nara. After the beginning of the 13th century, more complex methods of joinery were devised. Generally, a mortise and tenon with haunched keys, daimochi shachitsugi 台持車知継, were employed. Sometimes a tenon-and-mortise joint was used at the peak, but a wooden scab, *suitsuki arizan 吸付蟻桟, was attached to the interior face by means of wooden pins, *shachi 車知, that were pounded into slots prepared at the top of the bargeboards. These pins secured the scab, and the entire arrangement pulled the bargeboards tightly together at the peak.
