Ohmori Daikansho
The famous Iwami Ginzan (Iwami Silver Mines), a World Heritage site since 2007, were of great economic significance to the Shogunate and thus fell under its direct control. But actual administration fell upon the Daikan (Shogunal Representative) who ran things from here. The site consists of origina

History
Although the silver mines in Iwami were exploited from the 16th century, the history of the daikansho starts under the Tokugawa Shogunate. In 1601 Ôkubo Nagayasu was appointed as overseer of the mines and Ômori-daikansho was built as his offices. It appears there were more fortifications closer to the mines and on the surrounding mountains besides, such as Yamabuki Castle, to add to the area's defences, although the daikansho's role was chiefly administrative. Ômori-daikansho was also known as Mukai-jin'ya. In 1902 the main hall of the daikansho was re-built as the Nima District Hall, but the surrounding walls and nagayamon gatehouse were retained from the Edo Period. The silver mines continued to operate until 1923. In 2007 the Daikansho was part of over a dozen sites inscribed as part of the Iwami Ginzan World Heritage Site.
Field Notes
The famous Iwami Ginzan (Iwami Silver Mines), a World Heritage site since 2007, were of great economic significance to the Shogunate and thus fell under its direct control. But actual administration fell upon the Daikan (Shogunal Representative) who ran things from here. The site consists of original structures: the nagayamon (row house and gate house combined), built in 1815. The main hall, which now serves as the Iwami Ginzan Museum, was built in 1902 as the Nima District Hall. The latter's architecture, though evidently Meiji Period, is the inheritor to a form typical to daikansho (as seen at the Mizuhara-daikansho, for example), but I don't know how similar it is to the original main structure.
