Teshirojō was built as a branch castle of Kurahonejō, located 1km away further along the mountain ridge, which was controlled by the Kiyono Clan, which later served the Murakami Clan before breaking away in 1550 along with the Terao Clan to side with the Takeda Clan. Teshirojō was likely incorporated into the castle network taken over by Takeda Shingen in 1553 following his advance into northern Shinano. The Kiyono Clan fell firmly under the Takeda hegemony by that time. Teshirojō was abandoned at some point prior to the Edo Period, either following the demise of the Takeda Clan in 1582 or the relocation of the Uesugi to Aiźu in 1598.
Teshirojō is a lonely, small site, consisting of a main bailey and some subsidiary enclosures. It was built on a kofun (there are lots of kofun in the mountains here) which has its burial chamber now uncovered. This is apparently a power spot. Maybe all of Japan should be declared a power spot? I found an unmarked kofun by myself in trying to find more remains of Teshirojō.
