(The terms 'the Land of the Rising Sun' and 'the Land of the Setting Sun' appeared in Buddhist scriptures of those days [such as "Daichidoron" (Commentary on the Great Wisdom Sutra), the annotation of "The Great Treatise on Perfection of Wisdom"]; for example, "the term 'Land of the Rising Sun' refers to the east, and the term 'Land of the Setting Sun' refers to the west."
（なお「日出處」「日沒處」は当時の仏典（『摩訶般若波羅蜜多経』の注釈書『大智度論』など）に「日出処是東方日没処是西方」とある。)
