Japan's Tokachi Volcano Alert Raised to Level 2 as Volcanic Activity Intensifies

The Sapporo Regional Meteorological Bureau raised the volcanic alert level for Tokachi volcano in Hokkaido from Level 1 to Level 2 on June 18, 2026, at 11:00 a.m. local time. The elevation in alert status indicates that volcanic activity has heightened, with a possibility of eruptions affecting areas approximately 1.5 kilometers from the 62-2 crater. The meteorological authority cited several factors contributing to the increased volcanic risk: intensified thermal activity near the 62-2 crater and Fushikozawa fumarole group, crustal deformation indicating deep magma movement since March, increased sulfur dioxide emissions, and elevated seismic activity in and around the 62-2 crater area.

Under Level 2 alert status (crater peripheral restriction), entry into the surrounding area is regulated as a precautionary measure. The three affected municipalities—Biei, Kamifurano, and Shintoku towns in Hokkaido—have been advised to enforce entry restrictions and monitor the volcano closely. The meteorological bureau issued specific warnings regarding the dangers posed by ballistic projectiles and volcanic rocks within 1.5 kilometers of the crater, as well as potential ashfall and smaller tephra that could be carried considerable distances by wind.

Local authorities have instructed residents and visitors to avoid hazardous areas and follow official guidance regarding safety procedures. The Sapporo Regional Meteorological Bureau conducted a press conference on the afternoon of June 18 to provide further details and explain the volcanic monitoring situation. Tokachi volcano remains under continuous surveillance, with authorities prepared to issue additional warnings should volcanic activity escalate further.
