Mt. Oyama (1,252m) has been a sacred pilgrimage mountain for 1,200 years. The main trail passes through cedar forest and the spectacular Oyama Afuri Shrine before reaching the panoramic summit with views of Mt. Fuji and Sagami Bay.
Mt. Oyama (大山, 1,252 metres) rises above the Isehara basin in the Tanzawa-Oyama Quasi-National Park in central Kanagawa and has been one of the most revered pilgrimage mountains in the Kanto region for over 1,200 years. Worshippers have climbed its steep cedar-forested flanks to reach Oyama Afuri Shrine since at least the 8th century; during the Edo period, mass pilgrimages from Edo (present-day Tokyo) numbered in the hundreds of thousands each summer, making the mountain one of Japan's earliest examples of organised mass travel. Today the mountain combines accessible hiking with ancient shrine architecture, old-growth cedar forest, and panoramic summit views encompassing Mt. Fuji, Sagami Bay, and the Yokohama skyline.
From Yokohama, the Odakyu Line to Isehara takes approximately 50 minutes (680 JPY). From Isehara station, the Kanagawa Chuo Kotsu bus runs to Oyama Cable Car (also known as Oyama Kablue) at the mountain's base in about 30 minutes (370 JPY). The cable car ascends in approximately six minutes to the Afuri Shrine Lower Station mid-point (1,000 JPY round trip), skipping the lower section of steep stone steps. Hikers who prefer to walk the full route from the bottom can ascend Koma-sando, a steep medieval pilgrimage lane flanked by tofu restaurants and ryokan, before joining the main summit trail above the cable car upper station.
The main summit trail (Omotesando) from the cable car upper station to the summit takes approximately 75–90 minutes and passes through magnificent old-growth cedar forest before reaching the Oyama Afuri Shrine upper sanctuary (Honsha) at 1,252 metres. The summit provides exceptional views: on clear days, Mt. Fuji is visible to the northwest, Sagami Bay to the south, and the Yokohama and Kanto Plain to the east. A descent on the alternate Shimono-sando trail provides scenic variety through the mountain's quieter western flank.
Oyama tofu has been the traditional post-hike meal for centuries; the restaurants lining Koma-sando and the base area serve tofu sets — yudofu (simmered tofu), agedashi tofu (deep-fried), and dengaku (miso-glazed) — that are inexpensive and restorative, with a full set lunch running around 1,500 JPY.

Tips for visiting
- Autumn foliage from late October to mid-November makes this one of Kanagawa's finest hiking day trips. Mt. Oyama tofu is a traditional post-hike meal.
When to visit
Late October to mid-November for peak autumn foliage along the cable car route and summit ridge; clear winter days (December–February) offer the sharpest Mt. Fuji views from the top. Arrive at the cable car base by 09:30 on weekends and in foliage season to avoid queues.
Frequently asked questions
How fit does a visitor need to be to reach the summit?
The ascent from the cable car upper station to the 1,252-metre summit takes 75–90 minutes on steep stone steps and forest trail with roughly 500 metres of elevation gain. A moderate level of cardiovascular fitness is required. The trail is not technical but the final section is persistently steep with uneven stone footing.
What should visitors bring for the Mt. Oyama hike?
Sturdy walking or hiking shoes with grip are essential — the stone steps can be slippery in wet weather. Bring water (vending machines at the cable car stations; none on the summit trail), a light waterproof layer, and sun protection. Trekking poles are useful for the descent.
Does the cable car operate year-round?
The Oyama Cable Car operates year-round with a brief maintenance closure that typically falls in late autumn. Operating hours vary by season; confirming the schedule on the Isehara City tourism website or Oyama Kablue official site before travelling is recommended.
What are the most celebrated seasonal events on Mt. Oyama?
Autumn foliage (late October to mid-November) draws large crowds for leaf-viewing along the cable car route and summit ridge. The Kito (purification fire ritual) at Afuri Shrine in July is a traditional summer highlight, and winter nights with snow on the upper trails attract experienced hikers seeking quieter conditions.
Is there an easier route for visitors who do not want to hike to the summit?
Yes — the cable car to the Afuri Shrine Lower Station and a short walk to the shrine is a worthwhile excursion in itself, with good views and forest atmosphere. The area around the lower shrine and the Koma-sando restaurants is fully accessible without reaching the summit.
