Mt. Oyama — Kanagawa's Most Powerful Spiritual Mountain

Rising dramatically from the Tanzawa mountain range in central Kanagawa Prefecture, Mt. Oyama (1,252 meters) has been one of the most important sacred mountains in eastern Japan for over 1,200 years, drawing pilgrims from Edo-period Tokyo in such numbers that the mountain road became known as the "Oyama Kaido" — a dedicated pilgrimage highway through the Kanto plains. The mountain's twin peaks are home to shrines dedicated to different aspects of the same deity, and the spiritual energy generated by the combination of dramatic mountain landscape, ancient ritual practice, and centuries of devotion makes this one of the most compelling power spots accessible as a day trip from the greater Tokyo area.

Highlights

The approach to Mt. Oyama begins at the Koma-sando, a stone-paved lane lined on both sides with shops and restaurants whose tofu specialties are famous throughout Kanagawa Prefecture. "Oyama Tofu," made with the mountain's pure spring water, is sold in multiple preparations — silken cold blocks with mountain vegetable accompaniments, deep-fried age-dofu, and elaborate multi-course tofu kaiseki meals that reflect the mountain's long association with Buddhist dietary traditions. Walking the Koma-sando while the smell of cooking drifts from open kitchen windows is itself a pleasure worth making the journey for.

The cable car (ropeway) ascends from the Koma-sando to the Afuri Shrine Middle Altar, from which a steep trail continues to the summit where the Upper Altar of Oyama Afuri Shrine presides over views extending from the Boso Peninsula in the east to the Izu Peninsula in the south, with Tokyo Bay gleaming in between. On exceptionally clear winter days, Mt. Fuji rises in perfect profile above the western ranges — a view that has inspired painters and pilgrims for centuries. The shrine's association with rain-calling (its deity is believed to control rainfall) made it particularly important to agricultural communities throughout the Kanto region.

The forest trails of Mt. Oyama are maintained for multiple levels of hiking ability, and the descent on the opposite side of the cable car route passes through old-growth forest of remarkable beauty. Wild mushrooms, mountain herbs, and seasonal wildflowers appear along the paths in their respective seasons, and the mountain streams that rush through the lower slopes are famous for their clarity.

Getting There & Tips

- From Shinjuku, take the Odakyu Line to Isehara Station, then a bus to Oyama Cable Car Base (approx. 90 minutes total) - The cable car operates throughout the year; check seasonal schedules as hours vary - The tofu restaurants along the Koma-sando are best enjoyed as part of the descent — reward yourself after the climb - Wear proper hiking shoes for the summit trail above the cable car terminus - The mountain is crowded on weekends throughout the year; Tuesday to Thursday offers the most peaceful experience

Best Time to Visit

Autumn foliage (mid-November to early December) is Mt. Oyama's most spectacular season, when the entire mountain blazes with color visible from the Kanto plains below. The "Oyama Fudoki no Oka" summer festival (late July to mid-August) sees the mountain illuminated at night, a spectacular sight from the lowlands. Winter offers clear summit views and an austere, deeply spiritual atmosphere along the snow-dusted shrine paths.
