Yamanashi Prefecture opened two new concrete emergency shelters for climbers on Mount Fuji's descent routes on June 22, 2026 [1].

These structures are designed to protect hikers from sudden volcanic eruptions or rockfalls, providing critical safety infrastructure on the mountain's most exposed paths.

The new shelters are located near the seventh and eighth stations [1]. Each concrete unit measures two meters in height, 2.5 meters in width, and 5.4 meters in depth [1]. Despite their compact size, each shelter can accommodate up to 135 people [2].

This expansion is part of a broader safety initiative to increase the number of available refuges. Prior to the addition of these two units, there were only four shelters available on the descent route [1].

Yamanashi Prefecture officials said the goal is to significantly scale up the mountain's protective capacity. The prefecture plans to have a total of 13 shelters in place by fiscal year 2031 [1].

The timing of the unveiling coincides with the period leading up to the official mountain opening, ensuring the structures are ready for the peak climbing season. The shelters provide a reinforced environment for climbers who may be unable to reach a full base camp during a geological event [1].

“Each shelter can accommodate up to 135 people”

The systematic increase of emergency shelters reflects a growing administrative focus on disaster risk reduction for Mount Fuji's high volume of tourists. By transitioning from four to a planned 13 shelters, the prefecture is acknowledging the unpredictable nature of volcanic activity and the vulnerability of climbers on steep descent routes.
