The Nirayama daikansho (韮山代官所) was an Edo period government administrative center for the tenryō territories in eastern Japan during the direct control of the Tokugawa shogunate. It was located in what is now part of the city of Izunokuni, Shizuoka in the Tōkai region of Japan. There were once many daikansho located in various parts of Japan serving a similar function, and this is one of the few which remains in relatively intact. It was designated a National Historic Site of Japan in 2004.

Overview

The Nirayama daikansho administrated all of Izu Province (which was completely tenryō territory), as well as large portions of Suruga, Sagama and Musashi Provinces, as well as a portion of Kai Province and the Izu islands. Its kokudaka fluctuated at several points in its history, but was estimated to be at around 50,000 to 100,000 koku. The office of daikan was hereditary to the Egawa clan (except for a period from 1723 to 1758), and was regarded as equivalent to that of a hatamoto . The head of the Egawa clan always took the name of Egawa Tarō Uzaemon. The Egawa were a samurai clan who claimed descent from the Seiwa Genji who controlled central Izu since the Heian period. Similar to the daimyō, they also maintained a residence in Edo (located in Honjō). However, unlike the daimyō, they were not subject to the sankin kōtai requirement, but alternated residence between Edo in summer and Nirayama in winter. As the shogunal territories under their administration were scattered across a wide area, secondary offices were established at various locations for administrative and tax collection purposes.

In 1596, Tokugwa Ieyasu appointed Egawa Hidenaga (1560-1639) as daikan of half of Izu Province, with the remainder placed under the Mishima daikansho. The two offices were united to form the Niirayama daikansho in 1633. However, in 1723, Egawa Hidekatsu was found guilty of embezzling public funds intended for repairs to the Tōkaidō at Totsuka-juku and was relieved of his office. The clan regained the post in 1758; however, its scope of authority after this date was limited only to Izu Province, which it continued to govern until the Meiji restoration. In the Bakumatsu period, Egawa Hidetatsu played leading role in the shogunate's efforts to modernize its military against the threat posed by the Western imperialist powers, and was responsible for the construction of the nearby Nirayama Reverberatory Furnace for the production of cannons.
