The "Daichidoron (Commentary on the Great Wisdom Sutra, "摩訶般若波羅蜜多経," literally translated to the "Heart of the Perfection of Transcedent Wisdom")" written at that time indicated that such expression as the land where the sun rises only referred to the East of China, but some people mention that the expression of the King of Wa was avoided.
これは当時の仏典『大智度論』（『摩訶般若波羅蜜多経』の注釈書）などに「」とあるように東方にあることを示しただけとする考えもあるが、倭国王の表記を忌避したものと見る考えもある。
