It's worth a thousand kanmon to see
The broad area of the southern Izu Peninsula, including Nishiizu and Minamiizu, was made up of undersea volcanoes and volcanic islands that erupted before Izu collided with Honshu. Senganmon, located at the end of the promenade, and Mt. Eboshi, visible to the right of Senganmon, are part of the "root of the volcano" (volcanic neck) that was once a "magma passage" underground in an undersea volcano and has now emerged above ground.
At Senganmon, there is a tunnel (sea cave) carved into the center of the rock by waves, and its appearance resembling a giant gate was likened to the gate of Kumomi Sengenjinja Shrine at the top of Mt. Eboshi and so it was called "Sengenmon." However, it came to be called "Senganmon" because it is "worth seeing, worth a thousand kanmon."
