Kamiyashiki of Matsudaira Tadamasa

The was a large residential complex that was located outside Edo Castle in 17th century Japan.
History.
Matsudaira Tadamasa (1597–1645) was "daimyō" of Fukui Domain and a grandson of Tokugawa Ieyasu. His "upper residence" or main residence (上屋敷 "kamiyashiki") was in front of the Ōtemon gate of Edo Castle in what is now Ōtemachi, Tokyo. During the Edo period, a "kamiyashiki" was main residence of a "daimyō", and served as his primary residence and the residence of his official wife and heir, as well as much of his entourage while he was staying in Edo on "sankin-kōtai". It was also a place where he conducted the day-to-day affairs of the domain while he was in Edo. Most domains had a "lower" or smaller residence or retreat, called "shimoyashiki" (下屋敷), typically located in the outskirts of Edo, which also served as a place of refuge should the main residence be destroyed in one of the many fires which plagued the city. Some domains also maintained another spare Edo residence, known as the "nakayashiki" (中屋敷), located at some intermediate distance, which was often inhabited by the younger generation who would succeed to the lordship, or to a retired former lord.
This residence of Matsudaira Tadamasa was a magnificent Momoyama-style compound, constructed on a large lot. In 1657 however, during the disastrous Great Fire of Meireki, this mansion burned to the ground. Thereafter, such luxurious residences were no longer built.
Architecture.
The mansion consisted of a main building with two large roofs, constructed of cryptomeria wood. The residence was only one storey high in the typical "shōin" style, with large roofs for ventilation. Apart from the main residence there were other minor buildings for servants as well as a number of gardens with trees. The complex was protected by high, white-washed walls with two-storey watch towers at each corner. The main access to the residence was through two large gates, while there were minor gates for servants in the back. One broad gate was close to the "daidokoro", which was in the main part of the residence, while a second gate was reserved normally only for high visitors such as the "shōgun" himself. The gate for the "shōgun" was monumental in proportions, painted black with golden adornments, with two painted phoenixes above. The curved roof with the symbol of the Matsudaira clan above added to a sense of importance. A small moat ran along three sides of the mansion.
The layout and appearance was typical for the "daimyō" residences in the Ōtemachi area outside Edo Castle, as is evidenced in the depiction seen on the contemporary "Edo-zu byōbu" screens from the 17th century.
The 1/30 scale model in the Edo-Tokyo Museum was reproduced based mainly on three sources: illustrations in the "Iyo-dono yashiki sashi-zu" ("Illustrations of the mansion of the Governor of Iyo") which is in the possession of the Ikeda family archives at Okayama University, the "Edo-zu byōbu" ("Screens of Edo") in the collection of the National Museum of Japanese History, and the "Kōra Kōnen oboegaki" ("Memorandum of Kōra Kōnen") in the Tokyo Metropolitan Library. Some of the minor structures have been left out in the model in order to highlight the main buildings in the back. The minor buildings included servants quarters, storage, stables, etc. and their position is indicated by the beige layout on the white ground.
