Prince Ichinobe Oshiiwa - Prince Ichinobe of the Wrinkles

Date of birth and death unknown. A powerful member of the royal family in the mid-5th century. His father was Emperor Richu, and his mother was Kurohime, daughter of Ashita no Sukune, son of Katsuragi no Sotsuhiko. His children include Ichinobe Oshihawake no O, Iwasaka no Prince, Iwasaka Ichinobe Oshiha no O, and Ichinobe no O. Ichinobe is named after a place in Yamabe County, Yamato Province. He married Arinoomi no Omi no Hiehime, and gave birth to Emperor Kenso and Emperor Ninken. The Anko chapter of the Nihon Shoki states that Emperor Anko tried to pass the throne to Ichinobe Oshiha no O, who was a powerful successor to the throne and was related to the Katsuragi clan by marriage. Emperor Yuryaku resented this, and lured Ichinobe Oshiha no O, who was a powerful successor to the throne and was a member of the Katsuragi clan by marriage, to Kayano in Kutawata, Omi Province, on the pretense of hunting, and shot him dead. It is said that the two children escaped to Harima Province to avoid danger. Later, when his son, Prince Kokei, ascended to the throne as Emperor Kenso and searched for his father's bones, an old woman from Omi Province told him where they had been buried. He used the people to build a tomb on the eastern mountain of Kayano, and buried him there. There is a theory that he ascended to the throne, as there are posthumous titles such as "Ichinobe Emperor Mikoto" (Harima no Kuni Fudoki) and "Ichinobe Miyani Ame no Shita Shirashi Ame Yorozuku Ni Yorozu Oshiha no Mikoto", but there is no definite proof.

生没年不詳。5世紀中ごろの有力な王族。父は履中天皇、母は葛城襲津彦(かつらぎのそつひこ)の子葦田宿禰(あしたのすくね)の娘、黒媛(くろひめ)。市辺押歯別王、磐坂皇子、磐坂市辺押羽皇子、市辺王などにもつくる。市辺は大和国山辺郡の地名にちなむ。蟻臣(ありのおみ)の娘、荑媛(はえひめ)を妻とし、顕宗天皇、仁賢天皇を設けた。『日本書紀』の安康紀には、安康天皇が皇位を、葛城氏を外戚とする有力な皇位継承資格者であった市辺押磐皇子に伝えようとしたので、雄略天皇はこれを恨み、近江国来田綿(くたわた)の蚊屋野(かやの)に狩猟と称して、誘き出し射殺したと伝える。2人の子は難を避けて、播磨国に逃れたという。その後、子の弘計王(おけのおう)が顕宗天皇として即位し、父の骨を探し求めたところ、近江国の老婆が骨を埋めた所を教えてくれた。民を使って蚊屋野の東山に御陵をつくって、埋葬したという。「市辺天皇命」（『播磨国風土記』）、「於市辺宮治天下天万国万押磐尊(いちのべのみやにあめのしたしらししあめよろずくによろずおしはのみこと)」などと追号されていることから、即位説もあるが確証はない。
