In 1383, in an event known as the "Bloodletting Incident," Emperor Go-En'yû, suspicious that Azechi no Tsubone, one of his consorts, had been having an affair with Ashikaga Yoshimitsu, struck her on the head with a blade. Drawing a sword, or striking anyone with it, within the Imperial Palace was most unusual, and this incident caused quite an uproar. Assaulted with accusations, the emperor suggested he might retire to the mountains in Tanba province, and there commit suicide. He did not end up following through on this, however.
