Kanaoka-jinja, Shinto shrine in Kita-ku, Sakai, Japan

Kanaoka-jinja is a Shinto shrine in Kanaoka-cho, Kita-ku, Sakai, Osaka Prefecture. Its three honden stand side by side in the Kasuga-zukuri style, built facing west toward Osaka Bay because the shrine honours Sumiyoshi Okami, a deity linked to the sea. The haiden was rebuilt in the early Showa period, and two camphor trees estimated at 900 years old stand on the grounds.

According to shrine tradition, Kanaoka-jinja was founded during the Ninwa era (885–889), when Sumiyoshi Ōkami was worshipped along the Takenouchi Kaidō. Later Susanoo-no-Mikoto and Ōyamakui-no-Mikoto were added, and in the reign of Emperor Ichijō the painter Kose no Kanaoka was jointly enshrined, giving the shrine its name. It held the rank of gōsha, and in 1908 the Sumuchisone Shrine of Kuramae-chō was merged in before being separated again.

The shrine's name comes from the Heian-era painter Kose no Kanaoka, who is said to have loved this landscape and painted here; he was merged into the shrine's deities during the reign of Emperor Ichijo. Two camphor trees, one estimated at 900 years old, are designated preserved trees by Sakai City. A stele now marks the filled-in Kanaoka-buchi pond, where Kanaoka was said to wash his brushes.

Kanaoka-jinja is in Kanaoka-cho, Kita-ku, Sakai, not Osaka city. From Shin-Kanaoka Station on the Midosuji subway line it is about a 15-minute walk; from Shirazagi Station on the Nankai Koya line, about 20 minutes. Nankai buses stop at Kanaoka-jinja-mae. By car, head south from the Kanaokaguchi intersection of Osaka Central Loop Route 2.

Two camphor trees stand on the grounds, one of them a sacred tree estimated at 900 years old; both are registered by Sakai as protected trees. The shrine also keeps a stone monument marking Kanaoka-kyō's brush-washing pond, formerly about 150 m northeast of the shrine and now filled in as an open square, with an inscription brushed by Naohiko Masaki.
