Naohito, Prince Kan'in[a] (7 October 1704 – 3 July 1753), was the founder of the Kan'in-no-miya, a cadet branch of the Imperial House of Japan.

[1][2] In the early Edo period, minor members from the Imperial family and Japanese nobles that were unlikely to succeed a title would become Buddhist monks and be excluded from succession; however, after the early death of Emperor Go-Kōmyō, the Scholar-official Arai Hakuseki found it imminent to create a new shinnōke for one of the imperial princes to retain the succession right, in case of main line of the Imperial family should extinct.

[5][6] Prince Naohito married his third cousin Konoe Shūsi (近衛脩子), younger daughter of former regent Konoe Motohiro, in 1715; she had two daughters, and the elder married to Tannyo (湛如) of the Ōtani family while the other died young.

Shūsi died young in 1727, and the rest of Prince Naohito's children were born to different concubines.

[9][10] Kan'in-no-miya was succeeded by Prince Naohito's third son Sukehito, whose mother was concubine Sanuki (讃岐) of the Itō clan.
