Shōkoku-ji (相国寺), formally identified as Mannen-zan Shōkoku Shōten Zenji (萬年山相國承天禅寺), is a Buddhist temple in northern Kyoto, first founded in 1382 by Ashikaga Yoshimitsu, with the existing temple complex having undergone several periods of extensive reconstruction and rebuilding in the succeeding eras.

The Ōnin War , also known as the Upheaval of Ōnin and Ōnin-Bunmei war, was a civil war that lasted from 1467 to 1477, during the Muromachi period in Japan. Ōnin refers to the Japanese era during which the war started; the war ended during the Bunmei era. A dispute between a high official, Hosokawa Katsumoto, and a regional lord, Yamana Sōzen, escalated into a nationwide civil war involving the Ashikaga shogunate and a number of daimyō in many regions of Japan.
