Editing Emperor Ingyō (section)

===Events during reign===
Early on in his reign, Emperor Ingyō chose to send envoys to Korea for medical assistance. Brinkley took note of this and stated that Korea was evidently regarded as the "home of healing science". He also attributed the "many other" arts which were borrowed from China.<ref name="Brinkley"/> In regard to reforms, Sholar [[William George Aston]] notes in his translation of the [[Nihon Shoki]] that when Ingyō reformed the system of family and clan names, it would have only applied to [[dominant caste]]. At the time the general populace of Japan kept their personal names and "cared little for geopolitics".<ref name="Aston1"/> Emperor Ingyō's later affair with "Otohime" is regarded as important by Brinkley as it illustrates the manners and customs at the time. He also suggests that the "atmosphere of loose morality" was in part responsible for Kinashi no Karu's incestuous relationship.<ref name="Brinkley"/>

It is agreed upon by [[Basil Hall Chamberlain]]'s translation of the [[Kojiki]], and Aston's translation of the Nihon Shoki that Prince Kinashi no Karu was probably appointed crown prince during his father's lifetime.<ref>{{cite web|url=https://sacred-texts.com/shi/kj/kj148.htm|title=Sect.

Marriage of children of the same mother of whom Kinashi no Karu was guilty of was considered incest.<ref name="Brinkley"/> Aston notes in his translation of the Nihon Shoki that it's doubtful Karu no Ōiratsume was banished by her father. Historically women have always been more lightly punished than men for the same offense, and "the particular character of the fault in this case makes such a discrimination all the more reasonable".<ref name="Aston1"/>

Francis Brinkley comments that four facts present themselves during Emperor Ingyō's reign: "Men wore wristbands and garters to which grelots were attached, that a high value was set for pearls, that metal was used for the construction of great man's gates, and the [[List of earthquakes in Japan|first earthquake]] is said to have been experienced in 416 AD". The latter of these things allegedly leveled the Imperial Palace at [[Kyoto]] from the severity of the Earth's tremors.<ref name="Hammer">{{cite book|url=https://books.google.com/books?id=6O8VyhDbUPgC&pg=PA62|title=The Catfish and the Keystone|work=Yokohama Burning: The Deadly 1923 Earthquake and Fire that Helped Forge the Path to World War II|author=Joshua Hammer|publisher=Simon and Schuster|year=2006|pages=62–63|isbn=9780743264655 }}</ref> Modern sources have since questioned the reliability of this "first earthquake", opting instead to recognize another that took place in Nara prefecture on May 28, 599 during the reign of [[Empress Suiko]].<ref name="Hammer"/>
