No firm dates can be assigned to this Emperor's life or reign, but he is conventionally considered to have reigned from 12 January 499 to 7 January 507.[3]
Buretsu is considered to have ruled the country during the late-fifth century and early-sixth century, but there is a paucity of information about him. There is insufficient material available for further verification and study.
Buretsu was a son ofEmperor Ninken and his mother isEmpress Kasuga no Ōiratsume (春日大娘皇女). His name was Ohatsuse no Wakasazaki (小泊瀬稚鷦鷯). He had no children.
Buretsu's contemporary title would not have beentennō, as most historians believe this title was not introduced until the reigns ofEmperor Tenmu andEmpress Jitō. Rather, it was presumablySumeramikoto orAmenoshita Shiroshimesu Ōkimi (治天下大王), meaning "the great king who rules all under heaven". Alternatively, Buretsu might have been referred to asヤマト大王/大君 or the "Great King of Yamato".
Buretsu is described as an extremely wicked historical figure. TheNihonshoki describes the 11-year-old Buretsu, in 500, cutting open the stomach of a pregnant woman and observing the embryo. In addition to his acts of personal cruelty, during his reign the general welfare of the nation declined severely. According to theTenshō, supposedly compiled byFujiwara no Hamanari, Buretsu was admonished byŌtomo no Kanamura.Nihonshoki likened his debauchery toDi Xin of theShang dynasty, but the record inKojiki has no such indication. There are several theories on this difference. Some believe that this was to justify and praise his successorEmperor Keitai, who took over under questionable circumstances, not having been in a position of immediate succession. In history textbooks available before and duringWorld War II, the negative parts of Buretsu's record were intentionally omitted.
If Emperor Keitai began a new dynasty as some historians believe, then Buretsu is the last Emperor of the first recorded dynasty of Japan.[4]
The actual site of Buretsu'sgrave is not known.[1] The Emperor is traditionally venerated at amemorialShintoshrine (misasagi) at Nara.
