The 10 Best Hikes in Japan You’ll Actually Want to Do

Japan is one of the most underrated hiking destinations on the planet.

Roughly three-quarters of the country is mountains, the trail network is enormous, and you can go from a sunrise hike above Tokyo to a multi-day alpine traverse in Hokkaido without ever renting a car.

A few practical things to sort before you go.

A JR Pass if you’re moving between regions, hut reservations for the alpine routes (they book out months ahead in summer), and reliable connectivity.

Cell coverage drops fast once you leave the cities, and most trail signs are Japanese-only, so having data for maps and weather isn’t optional.

The simplest fix is picking up Mobal’s Japanese pocket wifi at the airport. It connects to all four major Japanese networks at once — Docomo, SoftBank, au, and Rakuten. Supports up to 8 devices if you’re hiking in a group, and saves you the SIM-swap hassle on arrival.

With that out of the way, here are 10 hikes worth building a trip around.

1. Mt. Fuji

It’s the highest peak in Japan at 3,776m, it’s a near-perfect cone visible from Tokyo on clear days, and climbing it once is more or less a national rite of passage.

The official season runs from early July to early September, when the mountain huts are open and the trails above the 5th stations are maintained.

Four routes go to the summit: Yoshida (the most popular, with the most huts), Subashiri, Gotemba (longest and least crowded), and Fujinomiya (shortest and steepest).

Most people climb overnight to catch sunrise from the top, which means freezing temperatures, conga-line crowds at the bottleneck above the 8th station, and a long sleep-deprived descent.

2. Kumano Kodo

The Kumano Kodo is a network of pilgrimage routes through the Kii Peninsula in Wakayama, walked for over a thousand years to reach three sacred shrines deep in the forest.

It’s a UNESCO World Heritage site and the only pilgrimage in the world that shares dual-pilgrim status with the Camino de Santiago.

The Nakahechi route is the most popular for foreign hikers — roughly 40km from Takijiri-oji to Kumano Hongu Taisha, walking over 3-4 days through cedar forests, river valleys, and a handful of small mountain villages.

You sleep in minshuku (family-run guesthouses) each night, which include dinner and breakfast and book out months in advance.

Difficulty is moderate — there are climbs, but nothing technical, and the route is well-signed in English.

This is the trip to choose if you want a real multi-day Japan hike without committing to alpine terrain.

3. Yakushima (Jomon Sugi Trail)

Yakushima is a subtropical island off the southern tip of Kyushu, covered in cedar forests so dense and ancient they reportedly inspired Studio Ghibli’s Princess Mononoke.

The headline hike is Jomon Sugi — a 10-hour round trip from Arakawa trailhead to the island’s oldest tree, estimated at somewhere between 2,000 and 7,000 years old depending on who’s measuring.

The first few hours follow an old logging railway, which makes the approach surprisingly gentle for such a long day on your feet.

Locals say it rains 35 days a month on Yakushima, which is funny until you’re standing in it.

Bring real rain gear (not a poncho), start the trailhead bus at 4-5am, and budget the whole day — most people are back at the trailhead just before dark.

4. Kamikochi and the Northern Alps

Kamikochi is the alpine valley that shows up on every Japan tourism poster — a flat ribbon of crystal-clear river running between 3,000m peaks, accessible only by bus from mid-April to mid-November.

You can do it as a half-day visit, walking the boardwalks between Taisho Pond and Myojin Pond with the Hotaka Range as a backdrop.

Or you can use it as the gateway to the Northern Alps — Mt. Yari (Yarigatake), the Daikiretto traverse, and a network of mountain huts that lets you string together 3-7 day high routes.

This is serious alpine terrain above the tree line, not a place to wing it.

Book your huts in advance, watch the weather (afternoon thunderstorms are routine in summer), and start early.

5. Nakasendo: Magome to Tsumago

The Nakasendo was the inland post road that connected Edo (Tokyo) and Kyoto during the Tokugawa shogunate.

A short stretch through the Kiso Valley — between the post towns of Magome and Tsumago — has been preserved well enough that walking it actually feels like walking the original road.

It’s 8km, takes 2-3 hours, and is the easiest hike on this list by a wide margin.

Both towns ban cars from their main streets, so you walk in and out of stone-paved villages with wooden inns, water mills, and the occasional sake brewery.

There’s a same-day baggage forwarding service between the two towns (around ¥1,000–1,500 per bag) so you don’t have to carry your luggage between them.

This is the one to pick if you’re traveling with someone who doesn’t hike, or if you want a low-effort introduction to rural Japan.

6. Daisetsuzan Traverse

Daisetsuzan is one of Japan’s largest national parks, sprawled across central Hokkaido, and the closest thing the country has to true wilderness.

The full traverse from Asahidake to Tokachidake takes 5-7 days, crossing alpine plateaus, volcanic ridges, and tundra-style terrain that looks more like Alaska than mainland Japan.

Autumn colors here are the earliest and most dramatic in the country — peak is usually mid-September.

You’ll be hiking in brown bear territory, so carry a bell, make noise, and store food properly at the unmanned huts (some have bear-proof storage, not all do).

Cell coverage is mostly absent across the route, which is part of the appeal but also why serious hikers carry a satellite messenger here in addition to the usual setup.

This is not a beginner hike — it requires real backcountry experience and a flexible schedule for weather.

7. Tateyama (Mt. Tate)

Tateyama is a sacred mountain range in Toyama Prefecture — one of Japan’s three holy mountains alongside Fuji and Hakusan — topping out at Ōnanjiyama (3,015m) at the eastern end of the Tateyama Kurobe Alpine Route.

The route itself is a series of cable cars, buses, and tunnels that crosses the Northern Alps from Toyama to Nagano — engineering-as-tourism that’s worth doing even without the hiking.

From mid-April to late June, the buses pass through the Yuki no Otani Snow Wall — corridors of plowed snow that typically reach 14-16m on either side of the road (the historic record is 20m).

Once you reach Murodo (2,450m), you can do a half-day hike to Mt. Oyama for sweeping views of the surrounding peaks, or continue across the range on a multi-day route.

Weather changes fast at altitude here, even in midsummer.

Pack layers and check a mountain-specific forecast — Tenki.jp’s mountain weather section or Yamaten — not just the standard weather app.

8. Mt. Aso

Mt. Aso in Kumamoto is one of the world’s largest active calderas — a 25km-wide ring of mountains with smaller volcanic peaks rising from the center.

Nakadake is the most famous of those inner peaks, with an emerald-green crater lake and ongoing volcanic activity that closes the summit area periodically.

When it’s closed (and it has been for stretches in recent years), you can still hike the surrounding peaks — Takadake, Nekodake, and the Kuju range across the caldera all make for excellent day hikes.

Check the official Mt. Aso volcano alert level before you go. Level 2 and above close the inner crater, and Level 3 closes most of the surrounding area.

Pair this with a stop at the nearby onsen towns (Kurokawa is the best-known) and you have one of the best two-day outdoor trips in Kyushu.

9. Oze National Park

Oze is a high-altitude wetland sitting at around 1,400m where four prefectures meet (Gunma, Niigata, Fukushima, Tochigi).

It looks nothing like anywhere else on this list — boardwalks across miles of marsh, with mountains on the horizon and almost no elevation gain along the main route.

Two seasonal events drive most of the visitor traffic: skunk cabbage (mizubasho) blooms from mid-May through early June, and yellow day lilies (nikko kisuge) carpet the marsh in late July.

You can do it as a long day from a trailhead like Hatomachi Pass, or stay overnight in one of the mountain lodges and walk a longer loop.

It’s the most accessible hike on this list for older travelers or anyone with bad knees.

Stick to the boardwalks — the wetland ecosystem is genuinely fragile, and there are fines for stepping off.

10. Mt. Takao

Mt. Takao is a 599m peak about an hour from central Tokyo by train, and it gets more annual visitors than any other mountain in the world.

That sounds like a reason to skip it, but it’s actually the best jet-lag hike in Japan.

There are six numbered trails to the summit: Trail 1 is paved and easy (90 minutes up), Trail 6 follows a stream through the forest, and Trail 4 includes a suspension bridge.

A cable car and a chairlift cover the lower half of the mountain if you want to start higher.

The summit has a small observation deck and a few restaurants serving soba noodles and grilled rice balls.

On a clear winter day you can see Mt. Fuji from the top, which is the closest most visitors will get to the real thing without committing to climbing it.

Before you go: practical notes for hiking in Japan

A few things that aren’t obvious until you’re already there.

When to go

The broadest hiking window is May through October, but most alpine routes are only safely accessible from late June to mid-September because of snow.

Mt. Fuji’s official season is short: early July to early September.

Autumn colors peak first in Hokkaido (mid-September) and roll south through November — Daisetsuzan first, then the Tohoku and Northern Alps, then Kyoto and Kyushu.

Cherry blossoms get the press, but autumn in the Japanese mountains is the more impressive show.

Mountain huts and permits

Most major alpine routes use a mountain hut system rather than tent camping.

The huts include dinner and breakfast, run around ¥10,000–17,000 per person per night (Northern Alps huts are at the top of that range), and book out months ahead during the summer season.

You don’t need a permit to hike in Japan, but most prefectures ask you to file a tozan-todoke (a climbing plan) before serious mountain trips.

The Compass app handles online submission and is widely used across Japan.
