Volcano with a double caldera structure

The most popular feature on Aogashima island is its volcano with a double caldera structure. There are only a few kinds of volcanoes like this in the world and here is your chance to see one. The Outer ring mountain is called Ootonbu(大凸部) and The inner ring mountain is called Mt. Maruyama(丸山).

Ootonbu Park

This is the highest vantage point on Aogashima island and one of the best places from where to look down onto the volcano. You can get there by car, or on foot even, within minutes from the rural community and there you will find a Torii gate from the Toudaisho Shrine. When climbing the stairs beside the Torii gate, you can get a good view of the trees and moss growing alongside it until you arrive at the top of Ootonbu Park. If you want to have your picture taken with the volcano as a backdrop, this would be the best place for it.

Oyama observatory park

Another place where you can have a good look at the volcano to see is the Oyama observatory park. It takes only 7-10 mins from the promenade entrance to go up to the observatory park. You can not only see the volcano but also Hachijojima beyond the sea. Also, check out the sculpture of the pan‐Pacific zone.

Ikenosawa

Ikenosawa

Ikenosawa

Ikenosawa is an area on the inside of the volcano with a double caldera structure. This place is also very good for stargazing. There are several places where volcanic fumes rise up from the western slopes of Maruyama, and the geothermal heat(Hingya) and warmth of the area make for a pleasant place to lie down and look at the stars. The combination of seeing both the volcano and countless stars is super rare. There is a lush forest that stretches over a lava plateau.

Joman

Joman

Joman

Joman is the northernmost point of Aogashima. Grassy knowls all over and you might even see some whales from here in winter. You also don’t want to miss the small cattle farm in Joman. Again, a good place for stargazing with a clear sky and little artificial light.
