The mountain isn't very high, and because there are steps, it's suitable for beginners to climb. For some reason, the summit is mostly covered by clouds in August, even on clear days. Perhaps autumn is a better time for climbing.
When there's heavy fog, visibility is extremely low, and the humidity is very high, making it potentially dangerous to explore the crater's rim. The paths on the rim are very narrow, often requiring you to pass through vegetation as tall as a person, and the ground is quite slippery.
Sometimes, if it weren't for the signs, you wouldn't even realize there's a path, and some forks in the trail might lead you astray. Falling into the crater or slipping down the mountain is extremely dangerous.
If you only want to reach the summit, it's advisable to return the same way you came, as the remaining route is longer than the descent from the summit. It takes about 1 hour to reach the top from the trailhead, around 2 hours to complete the loop, and about 40 minutes to descend. Additionally, be sure to wear durable long pants, or you'll risk getting scratched by the vegetation.
If there are any clouds covering or about to cover the summit, I suggest you abandon the hike. Don't trust the weather forecast, as it is completely unreliable for predicting the weather...
Read moreOn a sunny day it's amazing! The crater is fascinating and the view over Hachijojima and the ocean is stunning. On a clear day you can see Miyakejima and Aogashima in the distance too.
Info I wish I'd known: From the car park closest to the top, it's a 2 or 3 hour roundtrip up to the crater, all the way around and back You have to climb 1280 steps to the crater. The view gets progressively better and the flora changes so it's not too boring. There is a slope alongside the big, uneven stone steps. Going down is surprisingly easy and quick. The path around the crater is narrow, unpaved, and sometimes there's a very steep slope on both sides. I am afraid of heights and it was a little scary but not impossible. Go slowly and use your hands if you need to. Because of this, I would avoid very windy and rainy days, it could be dangerous and you won't get a great view. There's a little path that goes inside the crater but it's easy to get lost. The shrine in the undergrowth is easy to find and...
Read moreI climbed Hachijo-Fuji from sea leave to the top. I started my hike from the ferry port to the summit. There’s actually a track that starts from behind the Hachijo Airport but is impossible to use because is extremely overgrown, so follow the main road up to the mountain circular road, bare right (opposite direction to the Furenai Ranch) and after few minutes walk along the road you’ll find the Hachijo-Fuji trail is on your left. The hike is easy but in constant ascend, I discouraged hiking during a hot summer day, since there’s not much shade and a lot of concrete. This hike is one of the most stunning that I’ve done, the view from the top is really something. Unfortunately, I couldn’t finish the rim walk due the strong wind, I could barely stand up, and for safety reasons after 15 minutes I dedicated to turn back. There is also a short hike that leads to a shrine inside the crater,...
