Emperor Ōjin
William George Aston justified not translating "wani" as "crocodile". He refers to the Ryūjin 龍神 "dragon god", his daughter Toyotama-hime 豊玉姫 "luminous jewel princess" (who married the Japanese imperial ancestor Hoori or Hohodemi), Dragon King myths, and the scholar Wani who served Emperor Ōjin.
