Sasamekura Mountain is the closest hiking trail to Earth Hostel Nikko Riverhouse — the trailhead is 600 metres upstream, a ten-minute walk from the front door. For guests who want a morning hike before the afternoon swim, or a gentle warm-up before tackling something bigger, Sasamekura is the one. The trail winds up into the southern mountains of Nikko through increasingly wild forest, passing a meditation hut and a washed-out stone trail section, before arriving at the gateway to an abandoned gold mine at approximately 75% of the way to the peak. Inside the mine: bats. At the base of the trail: one of the finest small cafes in the Nikko area, Seiryuin Yamagoya Cafe.

Why Sasamekura?
Most Nikko hiking trails require a bus ride of 40 minutes or more. Sasamekura does not. It is the only trail in the area that begins within walking distance of the hostel, making it the natural choice for mornings with a short window, for guests who want to test their legs before a bigger hike, or for anyone who simply wants to disappear into the forest without the overhead of planning.
There is also a genuine destination partway up: the abandoned gold mine. The mine was once active in Nikko’s southern mountains and the gated entrance appears at approximately 75% of the way to the true peak. Inside, in the dark, bats. The mine adds an unexpected layer of character to what could otherwise be a straightforward forest walk.
And at the base, Seiryuin Yamagoya Cafe sits 100 metres up the steep driveway near the trailhead — one of the finest small restaurants in the area, run by Hide-san, a chef and talented woodworker who made all the furniture himself. The combination of forest trail, gold mine, bats, and a wood-carved cafe makes Sasamekura a genuinely distinctive half-day experience.
Getting to the Sasamekura Trailhead
From Earth Hostel: Walk upstream along the river for 600 metres. The entrance sign on Route 149 marks the trailhead, with Seiryuin Yamagoya Cafe visible on the hillside above. The approach takes about ten minutes at a normal walking pace. This is the only trail in the Nikko area that requires no bus or shuttle from the hostel.
By car or taxi: The trailhead is on Route 149 in the southern Nikko mountains. GPS the Seiryuin Yamagoya Cafe and park near the road sign at the entrance.
The Trail
Trailhead to meditation hut: The trail begins straightforwardly — a clear path into the forest with a simple, pleasant character. Within the first section, a small meditation hut appears on the trail. This is an old wooden structure used historically for mountain meditation practices; it marks you’re properly on the route.
Forest section and washed-out trail: As the trail gains elevation, the path character changes. Sections of the trail are washed out — stone underfoot, evidence of seasonal water flow that has eroded the original path. This is the section that elevates Sasamekura from a casual stroll to a proper Class 2 hike. Footwork matters here; take it steadily.
Views and grass sections: Higher on the trail, the forest opens and views of the surrounding southern Nikko mountains appear. There are grassy path sections with a completely different atmosphere from the lower forest — open, quieter, the feeling of genuine remoteness close to the hostel.
Gold mine (~75% to peak): A gate marks the entrance to the abandoned mine. The cave inside is accessible and cool — a genuine historical feature of Nikko’s mining past in these southern mountains. Go in carefully, give your eyes a moment to adjust, and watch for bats roosting in the dark. We left empty-handed (no gold), but the bats were excellent.
To the full peak: Beyond the mine, the trail continues to the summit of Sasamekura. The full peak requires additional time beyond the gold mine stop. Most casual hikers turn around at the mine; those wanting the full summit should allow 30–45 minutes more each way.

Seiryuin Yamagoya Cafe
One hundred metres up the steep driveway near the trailhead is Seiryuin Yamagoya Cafe — a small, beautiful cafe run by Hide-san, who is both a skilled chef and a highly talented woodworker and wood carver. He made all the natural wood furniture in the cafe himself, including the long table outside, and sells hand-crafted sets of forks, spoons, and knives. For lunch and dinner, he makes 2 main dishes. Closed Wednesdays and the 2nd and 4th Tuesdays of each month.
The combination of a hike up Sasamekura and lunch at Seiryuin Yamagoya Cafe is one of the best half-day experiences in the immediate area of the hostel. No buses, no planning, no crowds.

Is the gold mine safe to enter?
The mine entrance is accessible and the first section is safe to explore. Bring a torch (headlamp). Do not go deep into unmapped sections. The bats are harmless and the cave is genuinely interesting.
