Tokai Shrine, Shinto shrine in Japan

Tokai Shrine is a Shinto shrine in Choshi, Chiba Prefecture, ranked as a gōsha (village shrine). Its deities are Watatsumi Ōkami and Sarutahiko Ōkami. The shrine was founded in the late Nara to early Heian period at Hirayama in the former Tokawa-ura, then moved to its present site after a tsunami. Its grounds hold a designated natural monument: an evergreen broadleaf coastal grove of tabunoki and sudajii trees, with yabunikkei, yatsude and kakuremino.

Tokai Shrine was founded between the late Nara period and the early Heian period at Hiroyama in the Utagawaura area, now part of Choshi's Utagawa district. A tsunami later forced the shrine to move to its present site. It holds the rank of gosha, a district shrine, and its grounds were designated a Chiba Prefecture Natural Monument on 24 April 1959.

The shrine's name, Tokai, means "crossing the sea", fitting a site linked to Watatsumi no Okami, the sea deity, and Sarutahiko no Okami, venerated by fishermen and travellers. The grounds hold a coastal forest of tabunoki and sudajii designated a Chiba Prefectural Natural Monument on 24 April 1959.

Visitors should allow time to observe simple rituals such as ringing the bell and hand washing before prayer. The location is easily accessible from nearby neighborhoods and sits in a quiet area lined with trees.
