Shiomi-dake
Mountain Prominent Shizuoka mountain within Southern Alps
A mountain in central Honshu’s Akaishi (Southern Alps), frequented by multi‑day hikers using mountain huts to traverse ridgelines and reach alpine viewpoints.
Tips for Visiting Shiomi-dake #
- Plan your visit for mid-summer to early autumn (typically July-September) when alpine routes are generally free of persistent snow and weather windows are more reliable for high-elevation hiking.
- Use the established Minami Alps trailheads and reserve any mountain huts well in advance-Shiomi-dake is in a remote alpine area with limited accommodation, so bookings and a clear itinerary are essential.
- Start very early for summit approaches and consider an overnight at a hut to catch sunrise views of the surrounding peaks (including clear views toward Mount Fuji on good days), which many day-trippers miss.
Best Time to Visit Shiomi-dake #
