Nakaizumi Jin'ya
Nakaizumi is a former jin'ya and goten (palace) site in downtown Iwata Municipality. 'Goten' here refers to a fortified lodging house used by the Tokugawa shoguns. No ruins remain of either facility and the site has now been developed over, though there is a small park with information boards and mo
History
Nakaizumi-goten began as a residence of the Aika Clan. Tokugawa Ieyasu would stay at their residence to go hawking nearby, and in 1573 Aika Naotomo donated the manor to Tokugawa Ieyasu who constructed Nakaizumi-goten on the site as early as 1578. Ina Tadatsugu is recorded as building a fortified compound in the vicinity in 1584, and this may have been on the same site; Nakaizumi-goten is also said to have been completed in 1587.
In the Edo period the earlier residence became a goten, one of many such fortified safehouses located along routes the shoguns would often travel along between Kyōto, Sunpu, Edo and, later, Nikkō. Nakaizumi-goten was fronted by a large berm and moat. Tokugawa Ieyasu used the Nakaizumi-goten extensively as it was also used as a lodging house during his falconing excursions. He stayed at Nakaizumi-goten a total of twenty-one times.
Nakaizumi-jin'ya was an early jin'ya dating to the Momoyama period, being constructed in 1590 by Horio Yoshiharu, lord of Hamamatsujō, for his deputies; it was later re-established by Tokugawa Ieyasu following his victory at Sekiǵahara.
In the Edo period, Nakaizumi-jin'ya, located opposite the goten, was used to administer the territory held by the bakufu (shogunate) in the area, throughout Tôtōmi Province, and even holdings as distant as Ōmi, Mikawa, Kai, and, later, Shinano. The territory was valued at 63,000 koku in the Edo period, and 76,000 koku by the Bakumatsu period. A castle-town developed around the jin'ya.
To the north a little distance was the Mitsuke-juku ('Mitsuke' also implies an inspection area or checkpoint), an inn-town along the East Sea Road. The histories of the goten and jin'ya are often conflated. The jin'ya was also destroyed at least twice. Firstly a large fire required it to be rebuilt in 1831. Then the jin'ya was levelled by the Ansei quakes, presumably the Tōkai quake of 1854.
Nakaizumi-goten was decommissioned in 1670 along with many other goten which had ceased to serve any purpose because the shoguns had stopped visiting the emperor in Kyōto, and its buildings re-purposed, such as for nearby temple gates. The jin'ya was later decommissioned upon the abolition of feudalism, and eventually some of its gates were likewise sold-off, though the daikansho later served as a magistrate's office for Shizuoka Domain between 1869 and 1871, a time when domains existed alongside prefectures (see 'fuhanken').
Field Notes
Nakaizumi is a former jin'ya and goten (palace) site in downtown Iwata Municipality. 'Goten' here refers to a fortified lodging house used by the Tokugawa shoguns. No ruins remain of either facility and the site has now been developed over, though there is a small park with information boards and monuments.
There are in total four relocated gates around Iwata Municipality associated with either Nakaizumi-goten or Nakaizumi-jin'ya, of which I visited three. The one I didn't know about until later is actually closest to the site itself, being the main gate of Chūsenji (Nakaizumi-dera?).
