hashibami 端喰

Also written hashibame 端嵌. Narrow long strips of wood made to cover the top and bottom of doors composed of several vertical planks itado 板戸, the cut ends of paneled doors *itakarado 板唐戸, and staggered shelving *chigaidana 違い棚. These strips of wood prevent warping from expansion and contraction due to seasonal heat and cold, and general weathering from wind and rain. This technique is practiced for both single-piece and jointed doors. Usually both ends are mitered *tome 留 at a 45 degree angle. The oldest hashibami method used wooden clamps like those found on the *Tamamushi no zushi 玉虫厨子(mid-7c) owned by Hōryūji 法隆寺, and on doors at Hōryūji Tōin Denpōdō 法隆寺東院伝法堂 (8th century), in Nara. There are many variations including honzane hashibame 本実端嵌, a true tongue and groove, and arikatazane hashibame 蟻形実端嵌, a tongue and groove joint in a dovetail shape.
