You’ve probably heard people call Hokkaido the "Wild West" of Japan. It’s a bit of a cliché, honestly. But if you actually make the trek into the center of the island, specifically into Daisetsuzan National Park Japan, you realize the cliché is actually a massive understatement. This place is huge. It’s the largest national park in the country, covering about 2,267 square kilometers. That’s bigger than some small countries.
Most tourists stick to the pretty flower fields of Furano or the canal in Otaru. They’re missing the point.
Daisetsuzan literally translates to "Great Snowy Mountains." The indigenous Ainu people had a much better name for it: Nutap-ka-ush-pe, or more famously, Kamui Mintara. The Playground of the Gods. When you’re standing on the edge of the Ohachidaira caldera, looking at steam vents hissing sulfur into a crisp 10-degree afternoon in August, you get why they thought gods lived here. It’s raw. It’s sort of intimidating. And if you don't plan your trip right, it’s remarkably easy to get stuck in a situation you aren't prepared for.
The Peak Where Winter Never Really Leaves
Let’s talk about Asahidake. It’s the highest point in Hokkaido at 2,291 meters. You can take a ropeway up most of the way, which makes it feel accessible. Don’t let that fool you.
I’ve seen people step off that ropeway in flip-flops in late September, only to realize there’s already a dusting of snow on the ground and the wind is whipping at 40 kilometers per hour. The weather here doesn't care about your itinerary. It changes in minutes. One second you're looking at the Sugatami Pond reflecting a perfect blue sky, and the next, you’re enveloped in a "gas" (the local term for thick mountain mist) so dense you can’t see your own boots.
The hike from the ropeway station to the summit is a steep, rocky slog. It’s basically volcanic scree. Every two steps forward feels like one slide back. But the payoff is the steam vents. These fumaroles are loud—like a jet engine idling underground. They’ve been screaming like that for ages.
Why the "First Color" Matters
Japan is obsessed with autumn leaves (koyo). Usually, this happens in November in Tokyo or Kyoto. In Daisetsuzan National Park Japan, it starts in mid-September. It is officially the first place in Japan to see fall colors every year.
It’s not just trees turning red. It’s the nanakamado (Japanese rowan) bushes turning a deep, bloody crimson against the yellow of the birch trees. If you’re a photographer, this is your Super Bowl. But here’s the thing: because it’s the "first," everyone and their grandmother tries to get to the Ginsendai trailhead at the same time. The local government actually has to restrict private cars and run shuttle buses because the mountain roads simply cannot handle the volume.

The Brown Bear Reality Check
We need to talk about the Higuma.
The Ussuri brown bear is not a "cute" forest creature. It’s a 600-pound apex predator. Daisetsuzan is one of the densest habitats for these bears in the world.
If you hike the popular loops, like the one around the Daisetsugen plateau, you will see signs of them. Scat. Claw marks on trees. Maybe even a fresh footprint in the mud. Most hikers wear "bear bells"—those little tinkling brass bells attached to their packs. Does it work? Some experts say it warns the bear so you don't surprise it, which is the goal. Others think it just sounds like a dinner bell.
The real danger isn't a random encounter on a wide trail; it’s the dense "creeping pine" (haimatsu) thickets. These pines grow low to the ground and are incredibly thick. A bear can be five feet away from you inside that brush and you’d never know until you stepped on it. Always make noise. Talk loudly. Sing. If you see a bear, don't run. Back away slowly. If you run, you’re just a giant squeaky toy to them.
The Secret Cross-Park Traverse
Most people do day hikes. They go up Asahidake, take a selfie, and go back to a hotel in Asahikawa.
The real way to see the park is the multi-day "Grand Traverse." This takes you from Asahidake all the way south to Tokachidake. We're talking 5 to 7 days of intense trekking through the roof of Hokkaido.
There are mountain huts (yamagoya), but they aren't the fancy European-style hotels with wine and three-course meals. Most are unmanned. Some are just emergency shelters. You carry your own food, your own stove, and you pack out every single piece of trash—including your own waste in some areas using portable toilet bags (keitai toire). It sounds rugged because it is.

But waking up at a campsite near Hakuun-dake and watching the sunrise over a sea of clouds? That stays with you forever. You’ll likely see the Pika (rock rabbit) or the Ezo Shima-risu (chipmunk) darting between volcanic boulders. These animals are ice-age relics. They’ve been here since the mountains were formed.
Sounkyo Gorge: The Easy Entry
If you aren't into shivering in a tent, Sounkyo is the main "hub." It’s a resort town built into a narrow gorge with towering columnar basalt cliffs. It looks like something out of a fantasy novel.
Two main waterfalls, Ginga (the Milky Way) and Ryusei (the Shooting Star), drop hundreds of feet down the cliff face. In winter, these freeze solid into massive pillars of blue ice, and ice climbers come from all over the world to scale them.
The town itself is... well, it’s a bit dated. A lot of concrete 1970s-era hotels. But the onsen (hot springs) are legit. The water is heavy with minerals and smells like sulfur. After hiking 15 kilometers, sinking into an outdoor bath (rotenburo) while looking up at the cliffs is basically the peak of human existence.
Logistics: How to Not Get Stranded
Getting to Daisetsuzan National Park Japan requires a car. Period.
Yes, there are buses from Asahikawa and Kamikawa, but they are infrequent. If you miss the last bus at 4:30 PM, you’re looking at a very expensive taxi ride or a cold night at the trailhead. Rent a car at New Chitose Airport or Asahikawa Airport. Make sure it has an English GPS or just use your phone.
Driving in Hokkaido is easy compared to Tokyo, but watch out for deer. Ezo-shika deer are everywhere, and they have zero survival instincts when it comes to cars. They will jump in front of you.

- Best Time for Hiking: July to early September.
- Best Time for Snow: December to March (Asahidake has some of the best powder skiing on the planet).
- Essential Gear: Rain shell (even in summer), bear bell, sturdy boots, and a paper map. Digital maps fail when your battery dies in the cold.
Misconceptions About the "Easy" Trails
People see the word "Park" and think of paved paths and handrails. Daisetsuzan is a wilderness area.
Take the Kogen Onsen "Marsh Pond" loop. It’s famous for autumn colors and bear sightings. To even start the hike, you have to attend a mandatory bear safety briefing at the local center. If a bear was spotted on the trail an hour ago, they close the trail. Just like that. No refunds, no arguments.
The trail itself is often underwater or deep mud. You need rubber boots (which you can rent there). It’s not a stroll. It’s a muddy, buggy, sweaty slog that happens to have world-class views.
The Kurodake side is another example. You take a ropeway and then a chairlift. From the top of the chairlift, it’s a steep climb to the summit of Kurodake. Many people stop there. But the real magic is "over the rim" into the caldera. The landscape changes from green peaks to a desolate, lunar wasteland of black sand and steaming vents. It feels like the end of the world.
Why This Place Still Matters
In a country as crowded as Japan, Daisetsuzan offers something rare: silence.
Real silence. Not the "quiet" of a temple, but the deep, heavy silence of a landscape that hasn't changed since the last glacial period. It’s a place that humbles you. It reminds you that the earth is alive—literally, under your feet, the ground is warm in places because of the volcanic activity.
If you go, respect the rules. Stay on the trails to protect the fragile alpine flora. Some of these tiny flowers take years to grow just a few centimeters; one misplaced boot-print can kill them.
Next Steps for Your Trip:
- Book your accommodation in Asahikawa or Sounkyo early. If you're aiming for the September autumn leaf window, book at least six months in advance.
- Download the Yamap app. It’s the gold standard for Japanese hiking maps and works offline with GPS.
- Check the Hokkaido official bear sightings map. It sounds paranoid, but it gives you a real-time look at where the Higuma are active so you can choose your trailheads wisely.
- Buy a bear bell at any local convenience store (Seicomart). It’s a cheap souvenir that might actually keep a 300kg animal away from your lunch.
The "Playground of the Gods" isn't a marketing slogan. It’s a warning. Treat the mountains with respect, and they’ll show you a side of Japan that most people don't believe exists.
