The 1572 siege of Iwamura was concurrent with Takeda Shingen's push into Tōtōmi province and the famous battle of Mikata ga hara. Akiyama Nobutomo, one of Shingen's "Twenty-Four Generals," set his eye on the great yamashiro (mountain castle) of Iwamura when Tōyama Kagetō, the commander of the castle's garrison, fell ill and died.

Akiyama negotiated the castle's surrender with Tōyama's widow, and took it without any bloodshed. The official keeper of the castle, a seven-year old lord called Gobōmaru, was taken to the Takeda home province of Kai as a hostage.
