Activity
Entô is borderless.
The Earth, born 4.6 billion years ago, and the Oki Archipelago, formed 660 million years ago, are both deeply connected. Humans first arrived in the Japanese archipelago 30,000 years ago, and Oki became a place of exile 1,000 years ago. In 2013, Oki was designated as a UNESCO Global Geopark, and today it stands as a place where you can connect with the Earth through the Oki Islands.
Take a journey to Oki and experience the timeless essence of the Earth. We are all part of this planet, and at Entô, there are no boundaries—between inside and outside, between people and nature. Gaze out of your window to see the islands before you and the vast sea beyond. Step outside and immerse yourself in nature, stroll through the town, and rediscover yourself at the Geopark. This is a one-of-a-kind Entô experience that can't be found anywhere else.
Entô Activity
Explore the island's beauty by walking along a peaceful satoyama (a traditional rural landscape) footpath or taking a gentle trek up a low mountain. Get close to the sea with underwater observation boats, sea scooters, and pack rafts. Ride through the town and mountains on an E-bike to experience the island's way of life. Discover the fascinating story of the island's unique nature—something that can't be fully appreciated with just a quick glance.

Underwater Observation Boat “Amanbow” Night Cruise
Ama Town, with fewer street lights, the sea is pitch black as the observation boat Amanbow moves leisurely on the water. However, there is a sparkling, fantastical world under the sea, just like a planetarium. Bioluminescent plankton floats silently in the ocean, glowing in time with the ripples made by the boat. Surrounded by the calm sea, you can experience the feeling of floating on the sea while gazing at the light of the starry sky. Duration: 35 minutes [The activity is available from April to October. The operation schedule is decided about a month in advance. Prior booking is recommended as the number of seats is limited.]
