As the island only has a few inhabitants there are not that many attractions. Nature however is beautiful and lush and definitely worth seeing.

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）.
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.
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 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 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.
After passing the sculpture of Oyama observatory park keep going straight and you will find the red color shrine in the woods. The small torii gates have collapsed and the atmosphere is rather mysterious. There are very steep stone steps leading from the entrance to Ootonbu, the highest point of the island. Those used to be the approach to the shrine. Before the trail along the ridge was built, people used the steep stone steps to pray.
When you walk around Aogashima, you might find some plants which you have never seen before. Let’s check them out! Just for your information, even though they are special, please DON’T collect them as we wouldn’t want them to become endangered species.
Otani watari is seen across warm regions from southern Japan to Taiwan. It is a plant designated as being endangered. You can find it in the Ikenosawa area. Large ferns grow from collecting fallen leaves and rainwater in the center of its leaves to create humus.
Ashitaba is a kind of leaf from the family Seriacea which grows on the Izu Islands. Ashitaba tempura, Ashitaba fried rice, Ashitaba dressed sesame seeds sauce, Ashitaba miso soup or boiled Ashitaba etc…. There are many ways to eat Ashitaba.
Oshima zakura is one kind of cherry blossom and Japanese endemic species. It blooms from the end of March to April and its flowers bloom at the same time as the leaves develop. Its mother species is Somei Yoshino cherry tree which is the most famous cherry blossom.
Sakuyuri is one kind of lily and the Izu Islands’ endemic species. Its flowering season is in July.
Gaku Ajisai belongs to the hydrangea family and is one of Japanese endemic species. Its flowering season is from May to July.
Hiking
Stargazing on Aogashima island
Cooking Lunch by Geothermal kettle
Natural sauna- Fureai Sauna
Mount Maruyama is part of the volcano which looks a bit like bavarian cream. You can walk all around this small mountain ridge within 60 minutes. As you can gather, there are not that many people who walk this mountain, so the nature here is lush and beautiful.
As you may know, Aogashima Island is one of the best places for stargazing in Japan. The night sky of the island is clear, beautiful and there are very few artificial lights. The place where the stars are visible especially well on the island is Oyama Observatory park. You might see Canopus (which is also known as the star of longevity) from here. Even when there are no stars, you might see the big and romantic moon in the night sky
If you come to Aogashima, we strongly recommend to order your 3 daily meals at your accommodation as there are no restaurants on the island.

Aochu- Shochu of Aogashima (Tasting sessions)
Shima zushi an authentic local dish from Hachijojima. This is local Sushi with the local low fish is marinated by special sauce including soy sauce and put mustard on it.
This is a hand-made and 100% natural sea salt which is made at the facility inside the volcano, Ikenosawa on Aogashima. It takes about a month to distill the product from seawater. The geothermal energy and steam from the volcanoes heat the seawater and slowly and surely produce salt. Only 160~180kg of salt can be made out of 3,000L of seawater. It is a very rare salt indeed.
Aochu is the original brand of sweet potato Shochu in Aogashima. There are several main brewers because originally, it used to be liquor made at home that the wife prepared for her husband. The tastes vary depending on the brewer or the year of manufacture. Please find your favorite one by trying all of them! Tasting sessions are arranged from 6:00pm at the Aochu brewery.
