context_page_description: Iitoyo, was a Japanese Imperial princess and possibly empress regnant. She was, according to traditional legend, ruler for a short period between Emperor Seinei and Emperor Kenzō. She was baptized as Empress Tsunuzashi in the list of emperors of Japan, written by Ernest Mason Satow.
context_section_description: After Empress Jingū, Princess Iitoyo is the second woman described in the chronicles, who was in government for a while. But just like this, she is generally not recognized as a ruling empress by historians and she does not appear in the official Japanese Emperor lists.In the 1219 written by the Buddhist monk Jien Japanese historical work Gukanshō found to Iitoyo as reigning empress following explanation:
  "Since the two brothers were adamant to let the other go first, in the second month of the year in which Seine died, their young sister, Seine, succeeded the throne as ruling empress. But she herself died at 12 months [Note .: elsewhere 11 months  ] of the same year. Perhaps this is the reason why we do not find their reign in the usual Imperial Chronicles and why we do not know anything about them. She was called Empress Iitoyo and it is said that they in Kinoe plans of the year 60-year cycle had prevailed.
  (Since the two brothers were unbending in deferring to each other, their young sister followed Seine on the throne as a reigning empress in the second month of the year in which Seine died. But she herself died in the 12th month of that same year. Perhaps that it is why we not find her reign listed in the ordinary Imperial chronologies and why people know nothing at all about her. She was calles Empress Iitoyo and it is said that her reign was in the kinoe-ne year of the sexegenary cycle. ) "

  Iitoyo's entry as Empress Tsunuzashi in the Emperor list by Ernest Mason Satow, Japanese Chronological Tables , 1874.
  Even after Isaac Titsingh's translation of Nihon Ōdai Ichiran , which was written in 1625, Iitoyo was not counted among the official tennō because she had ruled for less than ten months, but she had been given a posthumous Empress name after her death (Japanese:  飯 豊 天皇 Empress Iitoyo).  Iitoyo is also under other posthumous Empress name (Okurina) such as Empress Pagei  and Empress Tsunuzachi  also recognized as a sovereign empress on various occasions, for which information can also be found in the Nihon Shoki, if there is the term for her death bō is used, which is otherwise reserved exclusively for Emperors. 
  Historians have a variety of theories about their reign: Iitoyo, according to one, may be identical to Queen Taiyoo, a successor to Himiko under the rule of Yamatai. The historian Shinobu Orikuchi  sees her as the first ruling empress in the history of Japan, who combines the roles of the shaman and the sovereign. Mitakō Mihoo, on the other hand, believes that Iitoyo was a rival ruler at the time of the 26th Emperor Keitai (traditionally ruled 507–531) before he became the unified Yamato under his rule. Mizuno Yū even argues that the Emperor Seinei, Kenzō and Ninken did not exist at all and that Iitoyo reigned after Emperor Yūryaku for 15 years.
