Also called jōgomune 漏斗棟. A roof-style found on vernacular houses *minka 民家, mainly in Saga Prefecture. The main roof of the main building, omoya 主屋 (see *hon'ya 本屋) is composed of 4 ranges laid out to form a square around a totally enclosed central valley, from which the style derives its name, jōgo 漏斗 (a funnel). The roof is hipped and thatched and each range is rather narrow in cross section, 2-2.5 *ken 間 (approximately four meters). The ridges are covered with plain large tiles *hiragawara 平瓦 and decorated with horn-like thatch features, minnosu 耳子. The central valley is drained by means of a very large rainwater gutter *amadoi 雨樋 of overlapping, half-cylindrical tiles, also called jōgo. The gutter is supported by a ladder-like cradle of bamboo called a jōgo hashigo 漏斗梯子. It crosses one range of the roof space within the building to discharge water through a wall to an external channel. The style developed in the last decades of the Edo period, as an elaboration of *futamune-zukuri 二棟造 or *kudo-zukuri 竈造. Despite vulnerability to heavy rain, the style was regarded as resistant to typhoon winds, and among the wealthy farmers, enjoyed considerable popularity for a time.
