History
The name Mikuni, meaning three provinces, is said to come from the mountain's location at the boundary of the former provinces of Inaba, Hoki and Mimasaka. It stands as the principal peak of the Mikuniyama range, which divides Tottori Prefecture, made up of old Inaba and Hoki, into east and west. Both geographically and culturally it marks an important dividing line, and its inclusion among the 100 Famous Mountains of Chugoku has made it well known to climbers. For trail routes and historical detail, official sources are the surest reference.
Access
The mountain area spans Tottori City and the town of Misasa, as well as the town of Kagamino on the Okayama side, with the summit at roughly 35.35 degrees north and 134.01 degrees east. Reaching the trailheads is usually done by car, passing through the towns at the foot of the range. Because the massif covers several municipalities, your route and travel time depend on which trailhead you choose. Check the latest trail and parking information from official sources before planning.
Best season
Early summer, when fresh greenery spreads across the slopes, and autumn, when the mountainsides turn colour, are especially good for hiking. As the peak rises above 1,200 metres, temperatures are lower than on the plains and the weather can change quickly. Snow and ice are likely in winter, calling for proper gear and experience. Dress and equip yourself to match the season of your visit.
