Cape Sunosaki

The Genpei Jōsuiki, the expanded version of the Heike Monogatari written in the 13th century, mentions a failed invasion of Cape Suno, in what was then Awa Province.

Minamoto no Yoshitsune's gunki monogatari ("war-tale"), the Gikeiki, probably written in the Nanboku-chō period, mentions the landing of a boat party on Cape Sunosaki.

[1] Cape Sunosaki is a coastal terrace made of layers of mudstone dating to the Tertiary period.

Mount Mitarai, within the Sunosaki Shrine precinct, is home to a forest rich in castanopsis trees, a genus of evergreens belonging to the beech family, as well as the himeyuzuriha variety of Daphniphyllum.

It, along with the Cape Tsurugi Lighthouse on the Miura Peninsula are responsible for indicating the entrance to the Uraga Channel.
