Ouchi Yoshitaka (1507-1551) was the sengoku daimyo of the Suo Province and head of the Ouchi clan. He was a prominent figure in the northern Kyushu and Chugoku region, where he solidified the apex of his influence in the 1530s. After this territorial consolidation, a major military operation of his was attacking the Amago Clan – a major warrior family that primarily resided in Izumo Province. However, this operation was not successful. In Yoshitaka’s siege of Gassantoda Castle, the home base of the Amago Clan, his forces sustained guerrilla attacks and even suffered betrayal by a few people. This led to a period of decline for the Ouchi, which then acted as an impetus for Yoshitaka to shift his focus from domain expansion to arts, culture, and trade. With these efforts, Yoshitaka became one of the richest daimyo in the Sengoku Period. It is important to understand that in his efforts to expand his domain, or to solidify himself as an opulent patron, Yoshitaka kept a close relationship with the court. This is evident through his relationship with Emperor Go-Nara in Kyoto, as in return for legitimizing positions such as Acting Governor of Yamashiro (modern-day Kyoto), Yoshitaka sponsored many imperial rites that the Imperial Court would have struggled to perform otherwise. In exchange, Yoshitaka also received the title of Dazai no Daini, which acted as a sort of legitimation of violence from the court in his war against the Otomo. The extensiveness of this relationship is especially shown through how Yoshitaka was trusted with a potential move of the emperor’s residence and courtiers from Kyoto to Yamaguchi – one of the first major efforts to move the heartland of Japanese culture and imperial power away from Kyoto. However, this latter effort failed; many of his own men revolted, as they did not like seeing Yoshitaka privileging the Imperial Court and potentially undermining their own status in the Ouchi. In the end, Yoshitaka was cornered in the Tainei Temple incident. The result was the forcing of seppuku onto Yoshitaka, his courtiers, his ministers, and his family on September 30, 1551.
