Yanagihara-jinja, Shinto shrine in Japan

Yanagihara-jinja is a Shinto shrine in the Shimokōnuki district of Numazu, Shizuoka Prefecture. It is a shikinaisha (a shrine listed in the Engishiki) and was ranked as a sonsha under the modern shrine ranking system. The shrine stands about 500 meters northwest of its original site in Yanagihara and is dedicated to Ōyamatsumi-no-Mikoto, with Iwanagahime-no-Mikoto and Konohanasakuya-hime-no-Mikoto also enshrined.

The shrine's founding date is unknown; it stood at Yanagihara, about 500 m east-southeast of the present site, before being moved here. It first appears in the Nihon Sandai Jitsuroku in 859, when it received a court rank, and is listed in the Engishiki as the only Myōjin Taisha of Tagata District. In 1590 it was rebuilt and relocated after fires during the Hōjō and Takeda wars, and in 1875 it was ranked a gōsha.

This place is where local traditions remain active and visitors can observe traditional practices like bowing before entering or ringing a small bell. The simple offerings and personal items left by visitors show how the shrine is woven into the daily life of the community.

The shrine stands at Shimokanuki Miyawaki 335 in Numazu, about a 30-minute walk from Numazu Station on the JR Tokaido and Gotemba lines; buses and rental bicycles are also available. The shared New Year rite with Ōasa Shrine runs over three days: the mikoshi-washing ceremony at Wairi-dō beach on 15 January, Ōasa Shrine's festival on the 16th and Yanagihara's on the 17th.

The shrine's annual rite is held jointly with Ōasa Shrine, about 1.5 km southwest at the foot of Mount Ushibuse by the sea. Portable shrines from both are carried to the Gyōnyūdō shore, where bearers wade into the water for the "mikoshi-arai" purification on 15 January.
