Explore Volcanoes in Japan: 8 Best to Visit (Including Hell Valley)

If you're planning to visit volcanoes during your trip to Japan, you're making a great choice! This country has numerous volcanoes because it sits at the boundary of tectonic plates. Today, many volcanoes are popular attractions due to their spectacular views and natural hot springs.

Beyond the volcanoes, you could also explore Hell Valleys (Jigokudani) in Japan. Formed by volcanic activity, they are still constantly emitting steam from the vents to this day.

With plenty of volcanoes in Japan, choosing which ones to visit can be a challenge. In this article, I've handpicked 8 best volcanoes and hell valleys based on my firsthand exploration in Japan. Each attraction is iconic, offers unique features, and is easily accessible.

1. Sakurajima: Watch An Active Volcano in Action

Sakurajima in Kyushu is one of Japan's most active volcanoes. With minor eruptions happening almost daily, you might witness ash shooting up several kilometers into the sky.

There are two ways to visit Sakurajima: you can either view it from a distance at an observation deck in Kagoshima city, or take a ferry to the island for a closer look.

For a quick visit within a limited time, head to the Shiroyama Observatory in downtown Kagoshima. You'll enjoy a panoramic view of the volcano, the city, and the ocean all at once.

Got a bit more time? I suggest you combine both viewing options. Exploring the island lets you see the volcano up close and learn how locals coexist with it. Yunohira Observatory is highly recommended, as it's the closest viewpoint to the volcano.

Though Sakurajima is an active volcano, visiting it is a secure adventure. The area is constantly monitored and studied, with emergency plans well-prepared. For your health, it's a good idea to bring a mask just in case of ashfall during eruptions.

2. Mount Aso: Witness White Steam from the Crater

Just a 1.5-hour drive from Kumamoto lies Mount Aso, one of the world's largest active volcanic craters. You could see the steaming white smoke and the serene blue volcanic lake. Though it erupts only a few times yearly, this giant never sleeps. The close monitoring ensures your safety here.

You could walk halfway around the crater to get a close-up view. There's a hiking trail circling the entire crater, but it might be closed depending on the daily weather conditions.

Want to try something exciting? We could arrange for you to take a helicopter tour to admire the entire crater from above.

However, Mount Aso may close suddenly due to bad weather or high toxic gas levels. We could help you plan your visit flexibly, and check the real-time opening information on the Mount Aso official website. If the volcano is open, our guide will promptly take you there.

Moreover, I suggest wearing a mask when visiting. The steam contains sulfur gas, which smells like rotten eggs and may cause discomfort. If you have asthma, avoid visiting Mount Aso.

3.  Mount Omuro: Looks Like a Matcha Bowl

Unlike active volcanoes such as Sakurajima and Mount Aso, Mount Omuro in Izu is a dormant volcano that doesn't erupt. It is a bowl-shaped crater in Japan, and is now covered with vegetation for a more appealing look.

You'll explore Mount Omuro in a relaxing way. Hop on the cable car to the summit, then stroll around the circular trail to enjoy 360-degree views of the volcanic landscape. On very clear days, you might even catch a glimpse of Mount Fuji far away!

I highly recommend visiting Mount Omuro between May and September. The mountain looks its best during these months, with lush greenery that makes it look like a giant matcha bowl! Don't forget to apply sunscreen, as the strong sun exposure would make you tan (I learned from my lesson).

Looking for a cultural experience at a volcano that offers more than just a view? Mount Omuro is the right place for you! We could arrange for you to take part in the special mountain-burning ceremony in February, one of the traditional Japanese prayers for blessings.

4. Mount Fuji: You Shouldn't Miss It

Mount Fuji is Japan's most famous and highest volcano. With its snow-covered peak for half the year and its cultural significance in Japan, Mount Fuji attracts countless travelers each year. Although it hasn't erupted in over 300 years, it remains an active volcano.

The best way to admire the full view of Mount Fuji is by exploring the Fuji Five Lakes. Lake Kawaguchi is our top pick overall. It offers the best perspectives and is easy to reach.

You could also opt to climb Mount Fuji from July to early September. However, this is more of an outdoor experience than enjoying the scenery. Plus, the snowy peak has melted by then, leaving only rocks.

Want to admire Mount Fuji from the closest spot? Visit the Fifth Station of Mount Fuji. But you'll only see half of the mountain's view here, not the full panorama.

5. Owakudani: Take a Ropeway to Enjoy It from Above

Created by ancient eruptions, Owakudani is a volcanic valley and a must-see attraction in Hakone. You could see sulfur gases constantly rising from steaming vents, turning the stones in the canyon yellow, and hear the rumbling sounds from the vents.

If you prefer seeing volcanic landscapes but can only visit one place close to the top cities in Japan, Owakudani near Tokyo is the perfect choice.

The most chosen way to enjoy Owakudani is by taking a 10-minute ropeway. You'll enjoy the crater from above and pass through white smoke.

I still remember the moment I saw this crater from the ropeway and couldn't help but say "Wow!" Despite the sulfur gas smelling like rotten eggs, I'm willing to take the risk to visit again.

For a special visiting experience, we could arrange a nature walk along a trail with a professional guide. This safe and informative activity lets you get a closer look at the valley and learn more about it. However, the trail may be closed in bad weather.

Furthermore, sulfur gases may lead to discomfort. If you have asthma, a respiratory disease, heart disease, or a weak constitution, skip Owakudani.

6. Noboribetsu Jigokudani Valley: See the Volcanic Valley Up Close

Noboribetsu Jigokudani (Hell Valley) is located in Hokkaido, only a 1.5-hour drive from Sapporo. This geothermal area was formed after a volcanic eruption and is famous for its continuous release of steam and sulfur gases.

The name "Hell Valley" comes from ancient Japanese beliefs. People thought the rumbling sound of the steam and boiling water came from the land that resembled the Buddhist hell. Well, you can only admit the ancient Japanese had quite an imagination.

Visiting Noboribetsu Jigokudani offers an immersive experience. You'll walk along a sightseeing path to see hot springs and steam bursting out of the vents up close. Additionally, the area boasts more onsen ryokans and a richer onsen culture, making it Japan's most famous hell valley landscape.

Want to experience what ancient Japanese people truly meant by "hell"? Try to explore the valley at night. Once it's dark, the trail lights up, creating a mysterious and slightly scary vibe.

When visiting in winter, it's best to wear non-slip shoes. The snowy conditions can make the path icy and slippery.

7. Hells of Beppu: Unique Colorful Hot Springs

Hells of Beppu consists of seven hot springs, each with unique colors. This geothermal landscape is exclusive because it blends geothermal activity with abundant groundwater.

These seven hot springs are for viewing only since they are extremely hot, with temperatures exceeding 80℃ (176℉)!

Although each hot spring provides distinct colors and scenery, I suggest visiting only 3-4 of them. From my experience, exploring more might cause visual fatigue, and some onsens are quite boring. Here are my top 4 recommendations:

• Umi Jigoku (Sea Hell): Iconic for its blue color.
• Chinoike Jigoku: A must-see with its blood-red water.
• Oniishi Bozu Jigoku: A muddy onsen, different from the water-based ones.
• Kamado Jigoku: A yellow onsen offering more engaging onsen experiences.

8. Unzen Jigoku: Similar to Noboribetsu Jigokudani Valley

Unzen Jigoku in Nagasaki is similar to Noboribetsu Jigokudani Valley. Both places allow you to admire steaming vents and bubbling hot springs up close along the path. However, Unzen Jigoku boasts more historical stories and offers a quieter atmosphere with fewer travelers.

If you prefer peaceful, less crowded spots, and your trip includes Kyushu, Unzen Jigoku is an excellent choice. Since public transportation from Ngasaki to Unzen Jigoku is inconvenient and limited, having a private transfer is more recommended.

On the other hand, if you're looking for a hell valley that's easier to reach, with more hot spring hotels and activities nearby, choose Noboribetsu Jigoku Valley.
