are the only extant examples of this style. Zenshūyō - A style which takes its name from its creators, the Buddhist Zen sect, and which emerged in the late 12th or early 13th century on the basis of contemporary Chinese architecture. The zenshūyō was originally called but, like the Daibutsu style, was renamed by Ōta Hirotarō, a 20th-century scholar. Its characteristics are earthen floors, decorative curved pent roofs (mokoshi) and pronouncedly curved main roofs, cusped windows (katōmado) and paneled doors. Typical of the style is also the main hall (Butsuden), which has just one story but seems to have two because it has a covered pent roof called mokoshi. Setchūyō - an architectural style born in Japan during the Muromachi period from the fusion of elements from three preceding styles, the wayō, the daibutsuyō and zen'yō. It is exemplified by the main hall at Kakurin-ji. The combination of wayō and daibutsuyō in particular became so frequent that sometimes it is classed separately by scholars under the name . Layout and geomantic positioning Buddhist temple complexes consist of a number of structures arranged according to certain concepts or guidelines. The arrangement of the major buildings () changed over time. An early pattern had a gate, tower, kondō and kodō in a straight line from south to north. Corridors extended east and west from the flanks of the gate, then turned north, and finally joined north of the kōdo, forming a cloister around the pagoda and the major halls. This pattern, typified by Shitennō-ji in Osaka, came from China via Baekje; the Chinese style of Buddhist temples, though altered somewhat by China via Korean peninsula, ultimately was based on that of Chinese palaces, and this is evident in many of the basic design features which remain today in the temples of all three countries. A Buddhist temple complex in Japan generally follows the pattern of a series of sacred spaces encircling a courtyard, and entered via a set of gates. These gates will typically have a pair of large guardian statues, called Niō. In addition, many of the more important or powerful temples are built in locations which are favorable according to the precepts of Chinese geomancy. For example, Enryaku-ji, which sits atop Mount Hiei to the north-east of Kyoto, is said to defend the city from evil spirits by being placed in that direction.
