Saruda-jinja, Shinto shrine in Japan

Saruda-jinja is a Shinto shrine in Saruda-machi, Chōshi, Chiba Prefecture. Its main sanctuary, rebuilt in 1680, is a Chiba Prefectural Tangible Cultural Property, and the shrine grove is a Prefectural Natural Monument. The approach crosses the JR Sōbu Line on the Shinsengawa bridge, built by the railway company in 1897.

According to shrine tradition, Saruda-jinja was founded on the 25th day of the 11th month of the 25th year of Emperor Suinin's reign, and in 807 a shrine building was erected. Minamoto no Yoriyoshi donated shrine lands in the Kōhei era (1058–1065), and Ashikaga Haruuji presented a gold seal that survives. The hall burned in 1566 and 1573, was rebuilt in 1574, and the present honden dates from 1680.

The shrine's name comes from Saruda, the district of Chōshi where it stands, and its main deities are Sarutahiko Ōkami, Ame-no-Uzume-no-Mikoto and Kukurihime-no-Mikoto. It has long been worshipped for yahō-yoke, protection against misfortune from all directions. A trace of shinbutsu-shūgō remains: the shrine office closes on butsumetsu days of the six-day calendar.

Saruda-jinja is a five-minute walk from JR Saruda Station on the Sobu Main Line, or reachable by car via National Routes 126 or 356 and Chiba Prefectural Route 71. The approach crosses the JR Sobu line on a bridge built by the railway company in 1897. The shrine office closes on butsumetsu days, a remnant of Shinto-Buddhist syncretism.

The approach path crosses the JR Sobu Line on a bridge called Senjin-bashi, built by the railway company when the line reached Chōshi in 1897 and cut the path in two. A surviving trace of Buddhist-Shinto fusion: the shrine office closes on Butsumetsu days of the six-day calendar.
