Shoin-zukuri

Shoin-zukuri is a Japanese residential architectural style that developed during the Muromachi period, from 1338 to 1573, with its foundations established in the late Muromachi era and its refinement continuing through the Azuchi-Momoyama and Edo periods, evolving out of the earlier Heian-period shinden-zukuri style under Zen Buddhist influence to create a more practical aesthetic suited to the warrior class. It is defined by square posts and washitsu rooms floored entirely in tatami, together with a recessed alcove called a tokonoma, staggered shelves, a built-in desk positioned for a view, ornate sliding doors, square beveled pillars, and coved or coffered ceilings, with wooden shutters for weather protection; an entrance hall called a genkan emerged as a residential feature during the Momoyama period. Its typical plan features a core area surrounded by aisles and smaller spaces divided by fusuma sliding doors or shoji partitions. Originally favored by the warrior elite and monastery scholars, the style spread beyond military residences during the early Edo period and became the basis of the traditional Japanese house as built today.
