KEY WORD : architecture / general terms
Also called toyo とよ. A generic term for a gutter. When used in traditional architecture, it was generally made of bamboo or carved out of timber and attached to eave ends, *nokisaki 軒先, to catch the rain flowing down from the roof. The down-drain pipe was called tatedoi 竪樋. Depending upon their placement, they were called an inside gutter, uchidoi 内樋, an outside gutter sotodoi, 外樋, or an eave gutter *nokidoi 軒樋. A carved out gutter was called horidoi 彫樋. A curved gutter, yobidoi 呼樋, was used to connect the eave gutter with the down spout.
