Keya no Omon (Itoshima City, Fukuoka Prefecture)

Overview (history, characteristics, attractions)

Keya no Daimon is a sea cave (a large cavern or arch formed by sea erosion) located on the west coast of the Itoshima Peninsula. Characterized by a massive hole carved into the cliff face by years of wave erosion, it is large enough that sightseeing boats can take visitors close to the inside of the cave, making it one of Itoshima's most representative scenic spots. On sunny days and at sunset, the contrast with the color of the sea is beautiful, making it a popular base for photography, nature walks, and marine activities.

Highlights

• See sea caves up close from a sightseeing boat: Take a sightseeing boat departing from the harbor and get close to the inside of the caves. Experience the impressive scale of the caves and the wave formations up close (operations are subject to change depending on weather and wave conditions).
• Observation points: Take panoramic photos from the observation decks near the parking lot and along the walking paths. You can enjoy the magnificent scenery created by the sea and cliffs.
• Sunset and sunrise: The time when the low sun paints the surface of the sea is especially beautiful and popular with photography enthusiasts.
• Marine activities such as kayaking and SUP: You can also experience exploring the cave area from the sea on tours led by local guides (availability depends on the season and the operator).
• Exploring the surrounding coastline: A stroll along the rocky shore, past tide pools, and enjoying the sea breeze is very pleasant.
