Jin'ya

A jin'ya (陣屋) was a type of administrative headquarters in the Tokugawa Shogunate during the Edo period of Japanese history.

Jin'ya served as the seat of the administration for a small domain, a province, or additional parcels of land.

Jin'ya were equivalent in function to Japanese castles (城, shiro), typically used as the administrative seats of larger domains.

Additionally, jin'ya were found on shogunal lands and those headed by hatamoto, and within larger domains served as district headquarters (gun daikan-sho) and in geographical exclaves.

Others jin'ya had moats or earthen walls, in some cases left over from an earlier castle on the site.

The Takayama Jin'ya , a surviving Edo period jin'ya in Takayama , Gifu Prefecture , was the administrative headquarters of Hida Province .
