This preprint reexamines the structural characteristics of numerical records in the Nihon Shoki, focusing on resolving apparent chronological and genealogical contradictions. By assuming the application of a "double-year" calendar system and possible editorial misinterpretations during the compilation process, the paper proposes new hypotheses regarding several figures, including Emperor Jinmu, Takeuchi no Sukune, Yamato Takeru, and Emperor Keitai. It also discusses the implications for alignment with Chinese dynastic histories and explores the rationale behind the assignment of posthumous titles.
