Uehara-shi

...The court noble Nakahara Yasutomi visited the residence of Hori Magojiro, the Magistrate of Amada County, around this time, and left behind a rare record of the district office during the Muromachi period (Yasutomiki). Throughout the Onin War, the Hosokawa clan did not have internal conflicts like other shugo families, so the territory was relatively stable, but in 1579 (Bunmei 11), a conflict arose between the Naito clan and the Ichinomiya clan, and in 1582 the Naito clan was replaced as shugodai, with the Uehara clan serving as shugodai until 1593 (Meio 2). However, this replacement instead caused chaos in the territory, and, influenced by the Yamashiro Province uprising, a large-scale provincial uprising broke out in Funai County in September 1589 (Entoku 1).

*Some of the terminology that refers to "Mr. Uehara" is listed below.
