In page Emperor Kōbun:

"

Now, Japanese Imperial Household Agency and minority of contemporary historians[citation needed] place the reign of Emperor Kōbun between the reigns of Emperor Tenji and Emperor Tenmu; but the Nihongi, the Gukanshō, the Jinnō Shōtōki and majority of contemporary historians[citation needed] do not recognize this reign. Prince Ōtomo was only given his posthumous title and name in 1870.
