Money-Saving Tip: Odakyu’s “Oyama/Enoshima Freepass”
Odakyu sells a combined pass covering the round-trip train from your station to Isehara and unlimited bus rides between Isehara and the cable car stop. The cable car is not included, but if you plan to ride the bus multiple times (e.g., for a side trip), it can save money. Check the Odakyu website for current pricing from your departure station.
Trail Options
Option A: Cable Car + Summit Trail (Recommended for Beginners)
| |
Total time (lower hall to summit and back): ~3–3.5 hours
Notes: The cable car handles the first 696m for you. The remaining climb is steep but well-maintained. This is the standard route for most visitors.
Option B: Walk from the Approach Road (Intermediate)
Skip the cable car and walk directly from the approach road to the lower hall via either:
- Otokozaka (Male Slope, 男坂): ~30 min, steep stone steps, tiring
- Onnazaka (Female Slope, 女坂): ~45 min, more gradual, easier for families
Good for those who want a full walking experience from the base.
Option C: Yabitsu Pass Ridge Traverse (Advanced)
Take a bus from Hadano Station to Yabitsu Pass, then hike the ridge to the summit and descend via the lower hall and cable car. A longer route with varied scenery, requiring more preparation and time.
Time Required
| Segment | Time |
|---|---|
| Shinjuku → Isehara (train) | ~55 min |
| Isehara → Oyama Cable Bus Stop (bus) | ~30 min |
| Approach road walk to cable car | ~15 min |
| Cable car to lower hall | ~6 min |
| Lower hall → Summit | ~90–100 min |
| Rest at summit | 20–30 min |
| Summit → Lower hall (descent) | ~70–80 min |
| Tofu lunch at the approach road | ~60 min |
| Return bus + train | ~90 min |
| Total (estimated) | ~7–8 hours |
Leaving Isehara Station at 9:00 AM, you can realistically return home by 17:00–18:00.

Highlights at the Lower Hall and Summit
Afuri Shrine Lower Hall (696m)
- Panoramic view of Sagami Bay, Miura Peninsula, and Enoshima on clear days
- Sacred spring water (大山名水) available inside the hall — you can drink it
- Light food and drinks sold at a small shop nearby
Afuri Shrine Main Hall / Summit (1,252m)
- On clear days: Mt. Fuji, the Tanzawa Mountains, and even Tokyo Skytree are visible
- Toilet available (¥100 environmental fee requested)
- No vending machines or shops — bring all food and water
Oyama Shishi (大山獅子)
Near the lower hall: a large natural rock topped with two stone lions and surrounded by twelve zodiac animal figurines. The inscription reads “One of Japan’s Three Great Lion Mountains.” A quiet but distinctive piece of the shrine’s history.
After the Hike: Oyama Tofu
Oyama is known throughout Kanagawa for its tofu. The spring water from the mountain is used to make soft, clean-tasting tofu that you’ll find at several restaurants along the approach road.
- Tofu set meal (cold tofu, miso soup, pickles, okara): ¥1,500–2,500
- Konnyaku刺し (seasoned konnyaku — a local specialty): ~¥500
- Soy milk soft serve: ¥400–500
Restaurants start closing around 15:00–16:00. Aim to be back at the approach road by 14:30 if you want to eat.
FAQ
Q. Can I hike without using the cable car?
A. Yes — the Male and Female Slopes go from the approach road directly to the lower hall. Add 30–45 minutes and expect steeper effort.
Q. Is it suitable for children?
A. The cable car + lower hall area is family-friendly. The trail to the summit is steep and demands real physical effort — consider turning back at the lower hall with young children.
Q. Can I hike in the rain?
A. Light rain is manageable, but stone steps and rocky sections become slippery. Check the forecast carefully; avoid hiking in strong rain or thunderstorms.
Q. Are there toilets?
A. Yes — at the cable car station, the lower hall, and the summit.
Summary: Who Should Go to Mt. Oyama
- You want a day hike accessible from Tokyo without a full mountain commitment
- You’re a first-time hiker who wants a real “I climbed a mountain” feeling
- You’re interested in visiting a proper historic Shinto shrine in a mountain setting
- You want to pair a walk with a memorable local meal (tofu)
Mt. Oyama sits at the right balance — challenging enough to feel like an achievement, accessible enough to do solo or with beginners. The history goes back over 2,000 years. The views on a clear day are genuinely spectacular. And the tofu at the bottom is very good.
