Hokkaido’s high latitude means that despite the Daisetsuzan mountain range’s relatively low altitude (around 2,000m), its weather and climate are comparable to the 3,000m mountains of Honshu.

２.Hiking Gear
From mountain opening till mid-August
now cover remains in places in the Daisetsuzan Range even in summer. Light crampons (instep or spikes) are necessary in some places earlier in the summer season.
Hypothermia is a real risk even in summer, if hikers are caught out in worsening weather.
Clothing made of synthetic fibers are recommended.
Use an easy-to-adjust clothing layering system that allows for good body-temperature control.
