Legendary narrative

Ingyō is regarded by historians as a "legendary Emperor" of the 5th century. The reign of Emperor Kinmei ( – 571 AD), the 29th Emperor, is the first for which contemporary historiography is able to assign verifiable dates; however, the conventionally accepted names and dates of the early Emperors were not to be confirmed as "traditional" until the reign of Emperor Kanmu (737–806), the 50th sovereign of the Yamato dynasty.

According to Kojiki and Nihon Shoki, he was the fourth son of Emperor Nintoku and his consort Princess Iwa, and therefore a younger brother of his predecessor Emperor Hanzei. He sat on the throne after Hanzei died and ruled for 41 years. His name was .

Ingyō's contemporary title would not have been tennō, as most historians believe this title was not introduced until the reigns of Emperor Tenmu and Empress Jitō. Rather, it was presumably , meaning "the great king who rules all under heaven". Alternatively, Ingyō might have been referred to as or the "Great King of Yamato".

His consort was Oshisaka no Ōnakatsu no Hime. They had five sons and four daughters, including Emperor Ankō and Emperor Yūryaku. He reformed the system of family and clan names, because many named themselves false names using higher ranked clan or family names.

Events of Ingyōs reign

The earliest documented earthquake in Japan occurred during Ingyō's reign, in 416, when the Imperial Palace at Kyoto was leveled by the severity of the Earth's tremors.

Some scholars identify Ingyō with King Sai in the Book of Song. This would have been a king of Japan (referred to as Wa by contemporary Chinese scholars) who is said to have sent messengers to the Liu Song dynasty at least twice, in 443 and 451.

According to Nihon Shoki, the king of the Korean Silla Kingdom grieved very much when Ingyō died. To comfort the soul of Ingyo, he presented Japan 80 musicians.

The actual site of Ingyō's grave is not known. The Emperor is traditionally venerated at a memorial Shinto shrine near Osaka.

The Imperial Household Agency designates this location as Ingyō's mausoleum. It is formally known as , in Fujiidera city near Osaka.

略歷

反正5年（410年）1月，反正天皇在未立皇太子的情況下駕崩。群臣商討後欲推舉雄朝津間稚子宿禰尊為天皇，不過本人以健康理由辭退，皇位維持空位。允恭元年（412年）12月，雄朝津間稚子宿禰尊在忍阪大中姬的強烈請求下即位。

允恭天皇三年，自新羅請來醫者為天皇治病。四年（415年）9月，因氏族故意假借貴族之姓，特以飛鳥甘樫丘的盟神探湯（古傳之占卜法，或手入沸水沸泥、或置燒斧于掌，皆見其手有否潰傷之狀，用以占凶吉、辨是非）以辨真偽，於是將諸氏族的氏姓撥亂反正。

雖於允恭天皇廿二年（433年）立木梨輕皇子為皇太子，但允恭天皇廿四年（435年）卻與同母妹輕大娘皇女通姦。以占卜判明後，輕大娘皇女被流放到伊豫（參看衣通姫傳說）。

四十二年（453年）1月駕崩，新羅王派遣八十樂人為使者致祭。《古事記》記載崩年78歲，另《日本書紀》北野本卻有一說為81歲。
