A Complete Guide to Hokkaido in September: Indulging in Early Autumn Scenery and Flavors

September in Hokkaido is a gentle season, where the hustle of summer has quieted down, allowing you to feel the deepening arrival of autumn. Tourist crowds begin to thin out, the air becomes crisp and clear, and the climate is wonderfully comfortable—warm during the day but cooling significantly at night. This period, when the greenery of summer starts turning golden and the flavors of early autumn emerge, makes it one of the most balanced and perfect seasons for a trip to Hokkaido.

Climate and Packing Tips for Hokkaido in September

The average temperature in central Hokkaido during September ranges from about 15°C to 22°C, while temperatures in eastern and northern areas are cooler, generally between 10°C and 18°C. While the daytime is comfortable enough for thin long sleeves, it is not uncommon for the early mornings and evenings to drop below 10°C. Especially towards late September, some mountainous regions may even experience their first light frost.

Layering clothing is key. It’s advisable to bring a T-shirt along with a lightweight cardigan, a thin down jacket, and an outer layer that blocks the wind for peace of mind. Rain gear is essential; prepare a foldable umbrella or raincoat to handle sudden showers or changes in mountain weather. For shoes, choose something comfortable and non-slip. If you plan on hiking or trekking, proper trekking shoes are recommended.

Recommended Spots by Area

Sapporo & Otaru Area

As September arrives, the street trees in Sapporo begin to change color, making strolls through Maruyama Park and Odori Park particularly pleasant. In Jozankei Onsen, the autumn foliage gradually begins, allowing you to enjoy both hot springs and nature simultaneously. The Otaru Canal is beautiful during times when mist hangs over it, offering a relaxed trip where you can visit glass workshops or Kitaichi Glass Museum.

For dining, in addition to Jingisukan and Sapporo ramen, this is a stable time for delicious seafood, such as grilled salted autumn salmon and butter-grilled scallops.

Furano & Biei Area

Having passed the lavender season of summer, Furano transitions into an autumnal landscape where sunflowers fields and pampas grass sway in the wind. The hills of Biei change from green to a beautiful gradient of yellow, and the Blue Pond increases its transparency, reflecting the autumn sky. Cycling along the Biei River is comfortable due to the crisp air.

Asahikawa & Sounkyo Area

The flower beds in Asahikawa city are vibrant with fall colors, and the Asahiyama Zoo is lively during this season. In Sounkyo, autumn foliage begins towards late September, allowing you to enjoy both the remaining alpine flora and the start of the color change via the Kurodake Ropeway. Local specialties like Asahikawa ramen, Hitsubetsu tomatoes, and blue forest mushrooms are in season.

Tohoku & Kushiro & Shiretoko Area

Kushiro Marshland shows its autumn colors in September; the combination of early morning fog and the marsh’s stillness is truly magical. The hiking trails at Lake Akan (Shiretoko Five Lakes) are stable, and since it is also a time when brown bears are active, guided tours are recommended for safety. At Abashiri Lake and Natori Lake, you can enjoy vast scenery and crisp air before the drift ice arrives.

Natural Experiences Exclusive to September

Autumn Flower Field Strolls: Pampas grass, cosmos flowers, and various wild autumn grasses bloom in abundance throughout Furano, Biei, and central Hokkaido.
Valley Foliage Hiking: Enjoy the first colors of autumn around Sounkyo, near Lake Biei’s Blue Pond, and at Mount Asahi in Toya Lake.
Lakeside Cycling: Areas around Lake Shikotsu, Lake Toya, and Lake Kussharo offer pleasant breezes and views of the beginning fall colors.
Wildlife Observation: Shiretoko and Kushiro Marshland are excellent times to observe Ezo deer, raccoon dogs, and migratory birds.

Gourmet Guide: Enjoying Autumn Flavors

September in Hokkaido is a rich season where the bounty of the sea meets the harvest of the mountains. Freshly cooked rice from new grains has natural sweetness, making it the perfect time for salted autumn salmon or kelp-wrapped delicacies (kombujime). Hair crab fishing intensifies from late September, and snow crab also reaches peak deliciousness.

Scallops are firm and sweet, while sea urchin roe is rich from late summer into autumn. Pacific saury are particularly fatty and flavorful; pairing local Hokkaido beef steak or Jingisukan with seasonal vegetables is exceptional. As for fruits, after the Yubari melon season ends, apples, pears, and grapes become in season. Particularly, the pears of Furano and the apples of Kamikawa are intensely sweet and perfect for desserts.

Peak Foliage Viewing Times and Recommended Scenic Spots

The timing of autumn foliage varies greatly by region; it begins in the high mountain areas of Hokkaido’s northern and eastern parts in September. Sounkyo and the Daisetsuzan range reach their peak viewing time from mid-to-late September. Mount Asahi and Kurodake begin changing colors as early as early September.

Central Hokkaido peaks in late September to early October, while southern Hokkaido peaks around mid-October. If you want to enjoy the foliage early, choose areas like Kamikawa Town, Biei, or Furano. For a more leisurely enjoyment of autumn colors at the foot of the mountains, the areas near Sapporo such as Jozankei and Lake Shikotsu are suitable.

Key Planning Points for Your Trip

Since September marks the end of summer vacation, tourist crowds decrease, which means accommodation costs tend to stabilize, and popular spots are less congested—a definite advantage. However, be aware that late September can sometimes be affected by typhoons, so check the weather forecast frequently and plan a mix of indoor and outdoor activities for peace of mind.

Renting a car offers the highest degree of freedom, especially when touring Biei’s rolling hills or the eastern regions. Within Sapporo city or Otaru, public transportation is sufficient. Since temperatures drop at night, it is recommended to check if your hotel has adequate heating facilities for comfort.

Tips for Maximizing Your Hokkaido September Experience

Departing early in the morning allows you to observe beautiful phenomena like morning mist over marshlands and lakes, as well as observing active wildlife. Since daylight hours begin shortening in the evening, allow plenty of time for travel between locations. The air is exceptionally clear for photography, making distant views crisp, and the autumn light beautifully illuminates subjects with a soft glow.

Visiting local direct sales markets or morning markets allows you to purchase fresh vegetables, fruits, and processed goods at affordable prices. Enjoying an onsen (hot spring) paired with the autumn night sky doubles the sense of relaxation. Since the mineral quality differs by area—such as Sounkyo, Noboribetsu, Toya Lake, and Kussharo Lake—visiting multiple areas is highly recommended.

Summary

September in Hokkaido is a special time, transitioning from the vibrancy of summer to the tranquility of autumn. The climate is stable, nature begins to change color, and the food reaches its peak abundance. A journey that allows you to slowly savor the beginning of foliage colors, the crisp air, and the flavors of early autumn will create unforgettable memories.

By planning your trip strategically across different areas, preparing for layering clothes and rain gear, and scheduling time to simply enjoy nature and food, you can make the most of Hokkaido in September. We highly recommend visiting this season to experience a unique side of Hokkaido.
