Senganmon
静岡県賀茂郡松崎町雲見The wide southern area of the Izu Peninsula (including Nishiizu and Minamiizu) was created by underwater volcanoes which erupted as well as volcanic islands, because Izu collided with Honshu (mainland Japan). Senganmon which is at the end of a trail as well as Mt. Eboshi that is visible to the right of Senganmon are parts of the volcano’s core, originally pathways of lava underneath an underwater volcano that rose to the surface.
Senganmon has a tunnel (sea cave) that has been made by waves eroding the central part of the rock. Since it looks like a gigantic gate it was likened to the Kumomisengen Shrine gate at the Mt. Eboshi summit and was called “Sengenmon” (“mon” is Japanese for gate). However, it started to be called Senganmon which stems from the term “seeing it is worth a 1000 ganmon” (1000 is pronounced as “sen” in Japanese, and “ganmon” refers to an old Japanese monetary unit.)
