Naru-jinja, Shinto shrine in Japan

Naru-jinja is a Shinto shrine in the Narukami district of Wakayama, Japan. Its honden consists of two halls: the right hall enshrines Amenofutodama-no-mikoto, ancestor deity of the Inbe clan, while the left hall enshrines Hayaakitsuhiko-no-mikoto and Hayaakitsuhime-no-mikoto, deities of the water gate. The shrine is a shikinaisha, a shrine listed in the Engishiki, ranked as a myojin taisha, and its former rank under the modern system was sonsha.

Naru-jinja appears in the Engishiki register as a Myojin Taisha of Nagusa district, one of only four Kii shrines receiving offerings at the Tsukinami, Ainame and Niiname rites. In 859 it was raised from Junior Fifth Rank, Eighth Order, to Junior Fourth Rank, Eighth Order. Toyotomi Hideyoshi's 1585 Kii campaign devastated the area; the hall was rebuilt in 1719. In 1873 it became a village shrine, and in 1907 the Engishiki shrines Katamaoto and Katsuchi were moved into its grounds.

The shrine name "Naru" is linked in the Kiishū Zokufudoki to the sound of water flowing from the Naru-mizu and Naru-taki valleys, tying the site to the river. The grounds also hold the small Narutake Shrine, whose deity, a Baekje princess said to have brought sake brewing to Kii around the fifth century, is honoured at a stone hokora by the torii.

Naru-jinja stands at 1089 Narukami, Wakayama, about 12 minutes on foot from Hizenmangu Station on the Wakayama Electric Railway Kishigawa Line. Buses 90 and 94 of the Narukami line also stop near Narukami Jūtaku-mae, roughly 5 minutes away. The shrine shares its neighbourhood with Hizen Jingū and Kokusen Jingū and the Narukami shell mound, a national historic site.

In 1907, under the shrine consolidation ordinance, two smaller shrines listed in the Engishiki, Katamaoto-jinja and Katsuchi-jinja, were moved into the precinct. Katamaoto-jinja had stood about 300 metres to the northeast, where a stone marker dated 1724 still stands at the original site. The two are now worshipped together in one hall.
