Satomi Sanetaka of Awa invaded Kamakura, and the fighting destroyed many buildings and treasures of Tsurugaoka Hachiman-gū.
Background
The Satomi clan of Awa had expanded their power in Bōsō and were seeking an opportunity to advance into Sagami. In 1526, Satomi Saneyō landed on the Miura Peninsula and approached Tamanawa Castle held by the Hōjō. Whether Saneyō acted independently or under the direction of the main Satomi house cannot be determined from available records.
Outcome
After fierce fighting with the Hōjō forces at Tamanawa Castle, Saneyō penetrated into Kamakura city, set fires, and withdrew to Bōsō. In the resulting conflagration, Tsurugaoka Hachiman Shrine was destroyed, and most of its shrine buildings and pagodas were burned. The specific dates of the destruction cannot be confirmed.
