Nobunaga held a sumo bout in 1570 at Azuchi's Jorakuji. Shincho-Ko ki (English/ Elisonas and Lamers) p. 139.
"On the 3rd of the Third Month, Nobunaga summoned sumo wrestlers from throughout Omi Province and watched them compete in Jorakuji. The participants were
Shika of the Hyakusaiji, Kojika of the Hyakusaiji, Taito Seigon, Nagamitsu, Miyai Ganzaemon, Taishin of the Kawaraji, Hashi Kozo, Fukao Matajiro, Namazue Mataichiro, and Aoji Yoemon.
in addition to these, countless other wrestlers with good skills flocked to Jorakuji, all of them thinking to outdo the others. The referee was Kinose Zoshun'an.
Nobunaga summoned before him the two wrestlers who had won the most bouts, Nazume Mataichiro and Aoji Yoemon, and gave each of them a sword and a dagger with gold-encrusted sheaths. From this day onward they were admitted to Nobunaga's vassal band and were appointed sumo commissioners, the ultimate of honors for both men. The skillful and attractive sumo put on display by Fukao Matajiro on this occasion caught Nobunaga's eye, so he gave Fukao a present of some clothes--a happy event for Fukao."
Nobunaga no tame!
