A story or level of a building, used especially in reference to a pagoda. For example, a *gojū-no-tō 五重塔 is a five-storied pagoda, and a *sanjū-no-tō 三重塔 is a three-storied pagoda. Each story is counted, and therefore, first, second, third, fourth, and fifth stories are ichijū 一重, nijū 二重, sanjū 三重, yonjū 四重, gojū 五重, and so on. Examples: Hōryūji 法隆寺 Gojū-no-tō (late 7th to early 8th century) and Hokkiji 法起寺 Sanjū-no-tō (early 8th century) in Nara. The term is also applied to gates with two roofs or two stories *nijūmon 二重門, for example, Tōfukuji *Sanmon 東福寺三門 (1428) in Kyoto. Other words used to count stories include: *sō 層 and *kai 階; for example, the upper story, may be called jōsō 上層. Kai is most often used in the sense of buildings with various number of usable floors, for example, ikkai 一階, nikai 二階, sangai 三階, yonkai 四階, etc., meaning first, second, third, fourth, etc. floors. A single-storied building may be referred to as tansō 単層 and a multiple storied building as jūsō 重層.
