Answer
In Kyoto, during the Honnō-ji Incident, Nobunaga was forced to commit seppuku. He was betrayed by one of his generals, Akechi Mitsuhide, who launched a surprise attack on his temple lodging. Nobunaga, unable to escape the burning temple, chose to end his own life according to samurai tradition to maintain his honor. This dramatic event occurred on June 21, 1582, marking a turning point in Japan's Sengoku period.
