Shingan

Shingan [備衒; しんがん] is a city located in northern Shinkō Prefecture, on the middle portion of the Adari Peninsula. As of 2020, the city has a population of around 40,000. 
Shingan was a castle town in the Nittori period, and part of an area contested between the Ibari clan and various local warlords, most of whom resided in the region of Ōman [modern-day Seidai/Danchō] and wished to expand northwards. Shingan became the site of numerous conflicts between these forces, although the Ibari were significantly stronger than the Ōman lords and kept a firm grip on the township until it was eventually conquered by the Shin in 1180. By 1231, Shingan was inhabited by one of Shinkō's most famed konbūshin, Motoyama Kadabi, who took residence in Shingan Castle and also renovated it.
By the 17th century, Shingan had absorbed some of the small townships which lined the nearby coasts of the peninsula. The city prospered as a center for trade and commerce, with ceramics and sericulture being significant industries. The region was also used as a training ground for the prefectural army, and had an entire district serving the military base.
