Japan raised volcano alert level after increase in volcanic activity for Mount Tokachidake in Hokkaido, to a Level 3. Japan has raised the volcanic alert level for Mount Tokachidake in Hokkaido to Level 3 after an escalation in volcanic activity, resulting in closures of hiking trails, road and temporary tourism changes around one of northern Japan’s most popular mountain destinations.

The Japan Meteorological Agency (JMA) upgraded Mount Tokachidake’s volcanic alert level from Level 2 to Level 3 on September 12 at 9:30 a.m., meaning visitors are being restricted from approaching areas near the active crater due to the increased risk of volcanic hazards.

The warning comes during one of the most important travel periods for Hokkaido mountain tourism, as visitors normally arrive during autumn for hiking, scenic drives, volcanic landscapes and hot spring experiences. The latest restrictions mainly affect areas close to the volcano, while major tourism hubs such as Furano and Biei remain open.

Mount Tokachidake Activity Increases as Japan Moves Alert Level to 3

The Mount Tokachidake volcano alert increase was triggered by a rise in larger volcanic earthquakes, indicating stronger underground activity around the mountain.

According to monitoring information, larger-amplitude volcanic earthquakes have increased since August 17, with the strongest earthquake in the recent sequence recorded at around 8:20 a.m. on September 12. The shaking was considered strong enough to potentially be felt around the foothills of the volcano.

Mount Tokachidake has remained under close observation because of ongoing volcanic signs, including elevated thermal activity. Earlier in 2026, volcanic activity around the 62-2 crater had already increased, with a small eruption reported from the crater area while the alert level remained lower at that time.

The latest upgrade means authorities consider the possibility of an eruption affecting areas close to the crater to be higher, requiring stronger visitor controls.

Level 3 Alert Creates Three-Kilometre Restricted Zone Around Volcano

Under the new Level 3 volcanic alert, visitors are being warned to stay away from restricted areas surrounding the active crater.

The main danger zone extends approximately three kilometres from the 62-2 crater, where volcanic rocks could potentially be thrown during an eruption.

People located downwind of the volcano have also been warned about possible ash emissions and smaller volcanic materials that could travel beyond the immediate crater area.

The restrictions are designed to protect travellers, hikers and local communities from sudden volcanic changes.

Hokkaido Hiking Routes Closed During Peak Autumn Travel Season

The new volcanic restrictions have directly affected Hokkaido adventure tourism, particularly hiking activities around the Daisetsuzan mountain region.

Mount Tokachidake is one of the most recognised mountain destinations in Hokkaido and attracts visitors for its alpine scenery, volcanic landscapes and seasonal autumn colours.

However, hiking towards the Daisetsuzan mountain range has now been prohibited from two important access points:

The timing of the restrictions is significant because September and October are among the busiest periods for mountain tourism in Hokkaido, with travellers visiting to experience autumn foliage and outdoor activities.

Visitors planning hiking trips around Tokachidake are being advised to avoid restricted routes and check local updates before travelling.

Hot Spring Tourism Around Tokachidake Faces Temporary Closures

The volcanic alert has also affected nearby hot spring tourism facilities, which are an important part of the Hokkaido travel experience.

Several facilities around the mountain have introduced closures or restrictions following the Level 3 alert.

The closures highlight the impact of volcanic activity on local tourism businesses that depend on visitors seeking mountain retreats and traditional Japanese hot spring experiences.

However, the wider accommodation sector around Tokachidake Onsen has not been completely shut down.

Road Access Changes Affect Scenic Drives Around Hokkaido Volcano Area

The volcanic alert has also resulted in changes to road access near Mount Tokachidake.

The Tokachidake Skyline route has been affected, with vehicle access restricted between Biei Shirogane Onsen and Tokachidake Onsen.

A gate near the Fukiage junction has been closed, preventing travellers from driving through the affected section.

Public transport continues to operate, but some stops have been removed from routes.

Travellers planning scenic drives through the mountain area should review updated road information before departure.

Furano and Biei Remain Open for Visitors

Despite the Level 3 volcano alert, visitors do not need to leave the wider tourism areas of Furano and Biei.

The warning does not represent a general evacuation order for surrounding towns. Instead, restrictions are focused on areas immediately surrounding Mount Tokachidake.

Both destinations remain important travel locations in Hokkaido, known for:

• Colourful autumn landscapes
• Rural tourism experiences
• Local food attractions
• Scenic countryside routes

Travellers visiting these areas should understand that the alert mainly affects mountain activities rather than general tourism throughout the region.

What Should Travellers Do During the Mount Tokachidake Alert?

Visitors planning a trip to the Hokkaido region should take several precautions while the volcanic alert remains active.

Travellers should rely on official updates from the Japan Meteorological Agency and local authorities rather than unofficial information.

Mount Tokachidake Remains a Major Hokkaido Tourism Landmark

Located in central Hokkaido, Mount Tokachidake is an active volcano within the Daisetsuzan mountain region and remains one of Japan’s recognised natural attractions.

The mountain is popular among hikers because of its dramatic volcanic terrain, highland scenery and access to nearby hot spring areas.

Although the current alert has disrupted some tourism activities, the wider Hokkaido travel network continues operating. The restrictions are focused on reducing risks near the volcano while allowing visitors to continue exploring safer areas.

The situation will continue to be monitored by authorities, and access rules may change depending on future volcanic activity.

Japan raised the level of the Mount Tokachidake Volcano Alert to 3 due to enhanced volcanic earthquakes following which there were safety restrictions resulting in the closure of some hiking trails, altering access around the crater and affecting several tourism-related businesses in the region of Hokkaido.

The main point for the traveler is that Hokkaido is safe, but that the area around Mount Tokachidake is temporarily off-limits and that these restrictions will stay in place until the situation with the volcano improves.
