This paper applies the chronological correction model presented in my previous work, Observations on the Nihon Shoki from the Perspective of the Spring-Autumn Double-Year Calendar System, to further examine the descriptions of Wa in the Sanguozhi, Jinshu, and the Nihon Shoki concerning the third century. Revision history (Dates of revisions are based on Japan Standard Time (JST)): Because I skimmed over the account in the 6th year of Emperor Sujin’s reign, I mistakenly wrote that Princess Toyosukiiri-hime was appointed to worship both Amaterasu Ōmikami and Ōkuninushi, although it should have been only Amaterasu Ōmikami. This has been corrected. – 2025/09/11 Author's Note:This paper is licensed under CC BY-NC-SA 4.0.
