However, some people say that the Baekje side considered 'the 26th year of Shoo' was the introduction year of Buddhism to Wa, because 538 corresponds to the 26th year of Shoo based on the theory that he was enthroned in 513, and 552 also corresponds to the 26th year of Shoo based on the theory that he was enthroned in 527.
しかし例えば513年即位説に従えば538年は聖王26年となり、527年説では552年がやはり聖王26年となることから、百済側では「聖王26年」を倭への仏教伝来年次と考えていたとする見解もある。
