Emperor Nintoku
Sumiyoshi-taisha is a shrine with connections to the ancient Yamato royalty's diplomacy and sailing, protecting the Imperial embassies to China. As the head priests, the Tsumori clan also boarded these embassy ships. The embassies departed from Suminoe no Tsu, a port on the Hosoe-gawa (also known as Hosoi-gawa. Known as Suminoe no Hosoe in ancient times), a river located to the south of the shrine. Suminoe no Tsu is the oldest international port in Japan, and was opened by Emperor Nintoku. It was the Silk Road's entrance into Japan.
