"Zuisho" (the Book of the Sui Dynasty) vol.81, which is Retsuden (literally, a series of biographies) No.46, describes the ruler of Wa (supposedly, Japan) in the world of Dong Yi (eastern barbarians) (i.e. to the east of China), "whose surname was Ama, courtesy name Tarishihiko, and title okimi," which was later quoted in an article on Japan in the section of Dong Yi of "Shin To-jo" (New book of Tang) as "Yomei, who was Me-tarishihiko, first established diplomatic relations [between China and Japan (N.B. this Japan was allegedly distinguished from the kingdom of Wa)] in the sixth century" (N.B. the meaning of Me in Me-tarishihiko is controversial and some researchers insist that it refers to a navy or army secretary), thus suggesting that Tarishihiko should be identified as Emperor Yomei.
