Emperor Keikō
Emperor Keikō was recorded as 10 feet 2 inches tall (310.9 cm), who had at least 80 children from multiple wives. This claim would put him into the category of Gigantism if verified, although as with other aspects it was more than likely exaggerated. Other than Yamato Takeru, at least three of Keikō's children were ancestors of notable clans. Emperor Keikō died in 130 AD at the age of 143, and his son Prince "Wakatarashihiko" was enthroned as the next emperor the following year.
