is a style of Japanese residential architecture used in the mansions of the military, temple guest halls, and Zen abbot's quarters of the Muromachi (1336–1573), Azuchi–Momoyama (1568–1600) and Edo periods (1600–1868). It forms the basis of today's traditional-style Japanese house. Characteristics of the development were the incorporation of square posts and floors completely covered with tatami.[1] The style takes its name from the, a term that originally meant a study and a place for lectures on the sūtra within a temple, but which later came to mean just a drawing room or study.[2]
The foundations for the design of today's traditional Japanese residential houses with tatami floors were established in the late Muromachi period (approximately 1338 to 1573)[3] and refined during the ensuing Momoyama period., a new architectural style influenced by Zen Buddhism, developed during that time from the of the earlier Heian period's palaces and the subsequent residential style favored by the warrior class during the Kamakura period.[4] The term, meaning study or drawing room has been used to denote reception rooms in residences of the military elite as well as study rooms at monasteries.[5] A has a core area surrounded by aisles, and smaller areas separated by fusuma sliding doors, or shōji partitions constructed of paper on a wooden frame or wooden equivalents, and .[4]
The main reception room is characterized by specific features: a recessed alcove (tokonoma); staggered shelves; built-in desks; and ornate sliding doors.[4] Generally the reception room is covered with wall-to-wall tatami, has square beveled pillars, a coved or coffered ceiling, and .[4] The entrance hall (genkan) emerged as an element of residential architecture during the Momoyama period.[4] The oldest extant style building is the Tōgu-dō at Ginkaku-ji dating from 1485. Other representative examples of early style, also called shuden, include two guest halls at Mii-dera. In the early Edo period, reached its peak and spread beyond the residences of the military elite. The more formal shoin-style of this period is apparent in the characteristics of Ninomaru Palace at Nijō Castle as well as the at Nishi Hongan-ji (see photos above).
Conrad Totman argues that the development of the style was linked to a lumber scarcity, caused by excessive deforestation, which prompted the use of lower-quality, more abundant material. As larger, straight-grained trees became less accessible, "elegant wooden flooring gave way to crude wooden under-flooring that was concealed beneath tatami." Likewise, sliding wooden doors were replaced with fusuma, a lightweight combination of "stiff fabric or cardboard-like material pasted onto a frame made of slender wooden sticks," and shōji sliding panels served as a substitute for more elaborate paneled wooden doors.[6]
The simpler style used in the architecture of tea houses for the tea ceremony developed in parallel with . In the 16th century Sen no Rikyū established dedicated style teahouses characterized by their small size of typically two to eight mat, the use of natural materials, and rustic appearance.[7] This teahouse style, exemplified by the Joan and Taian teahouses, was influenced by Japanese farmhouse style and the style featuring tatami matted floors, recessed alcoves (tokonoma) and one or more ante chambers for preparations.
See main article: Sukiya-zukuri. By the beginning of the Edo period, the features of the and the teahouse styles began to blend. The result was an informal version of the style called .[8] The style has a characteristic decorative alcove and shelf, and utilizes woods such as cedar, pine, hemlock, bamboo, and cypress, often with rough surfaces including the bark.[8] Compared to the style's, roof eaves in the sukiya style bend downward. While the style was suitable for ceremonial architecture, it became too imposing for residential buildings. Consequently, the less formal sukiya style was used for the mansions of the aristocracy and samurai after the beginning of the Edo period.[8]
