Karasugasen, Mountain at Tottori Prefecture, Japan.
Karasugasen is a mountain straddling the border between Tottori and Okayama prefectures at 1,448 meters elevation. Dense forests cover the slopes and multiple trails wind through them, connecting parking areas at the base to the summit.
The mountain has marked the boundary between Tottori and Okayama since 1871 when Japan reorganized its modern administrative divisions. This geographical line was established as official borders were redrawn across the country.
The mountain holds meaning for local communities as a gathering place where seasonal celebrations and traditional practices bring people together. Visitors can sense how this landscape is woven into the daily life and customs of those who live nearby.
Hiking trails here are reliably open and walkable between April and November when weather conditions are most favorable. Rest stations and parking areas are positioned at the main entrance points to help you start your walk.
Rare alpine butterfly species live in the upper slopes above 1,200 meters and exist nowhere else but here. These insects occupy a remarkably small range and attract the attention of naturalists and collectors.
