Quick answer: Daisetsuzan National Park in central Hokkaido is widely described as the first place in Japan to see autumn colors. The upper slopes typically begin to change in early September, and the colors move down toward the valleys by about mid-October.

The Mountains That Start Japan's Autumn

Every year, the Japanese leaf-watching season opens high in the mountains of central Hokkaido. While much of the country is still enjoying late-summer warmth, the slopes of Daisetsuzan begin to glow with crimson, orange and gold. Japan's autumn color forecasts and travel columns often look to this park first, and that is exactly why it is such a popular topic as the season approaches. This guide explains what makes Daisetsuzan special, how the colors travel down the mountainsides, and how visitors can plan an easy, comfortable day among the first autumn leaves of the year.

The appeal is simple. Here the foliage is not framed by temple roofs or castle walls but by wide alpine plateaus, steaming volcanic vents and ridgelines that stretch to the horizon. Visitors get a different kind of autumn, one that feels open, crisp and wonderfully spacious. Let's look at the park, the timing and the practical details so you can enjoy it with confidence.

A Giant Park in the Heart of Hokkaido

Daisetsuzan National Park was established in December 1934 and covers about 2,268 square kilometers, an area roughly comparable to the whole of Kanagawa Prefecture. It was long Japan's largest national park, and it remains one of the most expansive wild areas in the country. The park holds sixteen peaks above 2,000 meters, and Asahidake, at about 2,290 meters, is the highest mountain on Hokkaido. The name Daisetsuzan is often translated as "great snowy mountains," which hints at how early winter arrives up here.

The landscape is a mix of volcanic cones, broad plateaus and deep forested valleys. The lower slopes are covered mainly in Jezo spruce and Sakhalin fir, while higher elevations are home to alpine meadows. Roughly half of the alpine plant species found on Hokkaido grow within the park, which gives the high country its patchwork of colors in every season. Hot spring towns such as Asahidake Onsen and Sounkyo Onsen sit at the edges of the mountains, so a day of hiking can end with a warm soak.

Why the Colors Arrive So Early

The explanation is mostly about altitude and latitude. Hokkaido lies far to the north, and Daisetsuzan's high ground sits well above the surrounding lowlands, so nights cool down quickly once summer fades. Cold nights and bright days are the classic recipe for strong red and yellow foliage. As a result, the upper slopes typically begin to change in early to mid September, which is earlier than anywhere else in the country's usual leaf-viewing calendar.

Once the show begins on the heights, it moves downhill day by day. On Mount Kurodake, the colors usually appear from early September near the summit, are often at their best on the upper levels in the second half of September, and then reach the valley floor around mid-October. That slow descent gives visitors a long window, and it also means a trip can be matched to the elevation you prefer. Japanese rowan, known as nanakamado, is one of the trees that adds warm reds to the high country, and the mix of colors against evergreen conifers is a favorite for photographers.

Two Classic Ways In: Asahidake and Kurodake

For most visitors, the easiest entrances are two ropeways on opposite sides of the park. The Asahidake Ropeway starts at Asahidake Onsen, at roughly 1,100 meters, and carries passengers up to a station at about 1,600 meters. From there, walking paths lead across the upper slopes, with views of steaming fumaroles and the volcanic summit above. Hikers who want more can continue on longer routes toward the Susoaidaira Plateau, which takes roughly 60 to 100 minutes one way from the ropeway. Asahidake is an active volcano, so steam rising from the ground is a normal part of the scenery.

The other gateway is Sounkyo Onsen, where the Kurodake Ropeway rises to the fifth station and a chair lift continues to the seventh. Mount Kurodake stands at 1,984 meters, and the climb from the top of the chair lift to the summit takes about 60 to 90 minutes. Many visitors simply ride the ropeway and walk the short forest paths near the upper station, which already offers wide views of colored slopes. Strong hikers sometimes link the two sides over one or two days, but that is a serious mountain route and is best planned with current trail information.

Practical Tips for a Mountain Day

Dress for cold. Even in sunny weather, the temperature at the upper stations can feel like late autumn or early winter, and wind makes it feel colder still. Layers, a warm hat, gloves and a windproof jacket are sensible choices, along with sturdy shoes for gravel and rock. If you plan to hike beyond the paved or gravel paths near the stations, carry water, snacks and a map, and check the weather before you start. Mountain conditions change quickly, and local visitor centers are happy to share trail updates.

Ropeway hours are limited, so plan your return time early, and arrive in the morning if possible, since clear air often gives the sharpest colors before clouds build in. Hokkaido is home to brown bears, so follow posted notices, keep to marked trails and stay alert in forested areas. Both hot spring towns can be reached by local bus or by car from the Asahikawa area, though services are limited and schedules change by season. As of autumn 2026, it is wise to confirm ropeway operation, fees and bus timetables on the official sites before you travel.

The same slopes also reward patient photographers. Early light brings out the contrast between red shrubs and dark conifers, and late afternoon sun warms the whole plateau. After the hike, a hot spring soak at Asahidake Onsen or Sounkyo Onsen is a fine way to relax tired legs.

Quick Takeaways

Daisetsuzan is widely described as the first place in Japan to see autumn colors, thanks to its altitude and northern location. The color usually starts at the highest levels in early September and slides down the mountains toward the valleys by mid-October. Asahidake and Kurodake each offer a ropeway that makes the scenery reachable without a long climb, while longer trails reward experienced hikers with plateaus, volcanic vents and sweeping views. Pack warm layers, start early, and keep a flexible schedule in case the weather turns.

Most of all, treat the trip as a chance to see autumn in a very different form from Kyoto's temples or Tokyo's gardens. Here, the leaves share the stage with open sky and alpine air, and the whole experience feels fresh, quiet and bright. Whether you spend an hour near the ropeway station or a full day on the trail, Daisetsuzan is a beautiful place to begin the Japanese autumn.
