Emperor Nintoku
On the basis of this ancient inscription, Korean scholar Kim Woon-Hoe theorizes a fraternal relationship between Emperor Keitai of Japan and King Muryeong of Baekje. A mirror was excavated from the tomb of King Muryeong. It is similar to the mirrors of Emperor Nintoku and Emperor Keitai. In the ancient Buyeo kingdom, the bronze mirror represented the king.
