Abstract
In Edo period, there was a building named "SYOIN" especially in the Ex-emperor's palace among many Emperor's, Empress', Ex-emperor's and Ex-empress' palaces which are called "the Kyoto Imperial Palace". "NIKAI-SYOIN" (2 stried SYOIN) and "KO-SYOIN" (small SYOIN) of the GOYOZEI-IN's palace (built in 1607) are the first buildings built for the reception in Edo period. From this case, "SYOIN" had taken the place of one of the main buildings in the Ex-emperor's palace. Its function was to recept court nobles or feudal lords, and since 1687 when the Ex-emperor's palace was built for the Emperor "REIGEN", it is recognized that this function was fixed. On style, this building had been built by the style of the Edo period and little by the traditional style of the court noble's residence. As conclusion, in Edo period, "SYOIN" of the Ex-emperor's palace among the all Kyoto Imperial Palaces was the most typical building having the style, plan, function and etc. of the residence in Edo period.
