Is October Right for You?
Weigh the advantages and considerations before booking
- + The larch forests ignite into gold and amber, giving you the most photogenic hiking backdrop you'll see all year
- + Hot springs sit empty - no queues at Niseko's famous onsen, and the 43°C (109°F) water feels even better against the 10°C (50°F) mountain air
- + Room rates drop 40-60% from winter peaks, so you can afford the valley's best hotels without the powder tourist markup
- + October is mushroom season - locals head to the slopes with baskets for matsutake hunting, and restaurants serve them fresh, not frozen
- − Most gondolas and ski infrastructure are closed for maintenance, so you'll need to hike for views instead of riding lifts
- − Days are short - sunset hits by 5:30 PM, which cuts hiking time shorter than most visitors expect
- − Some restaurants and bars shutter completely, those that survive on winter ski crowds

Best Activities in October
Top things to do during your visit
October is the only month when the larch forests turn electric yellow, and Mount Yotei's summit trail is empty. The 6-hour round trip starts at 7 AM when temperatures hover around 6°C (43°F) but the climbing keeps you warm. By 10 AM, you're above tree line with views across the entire Shiribeshi range, and the descent through golden larches feels like walking through a Japanese painting. Weather is stable 80% of October days, unlike the summer thunderstorms that plague July.
Perfect October weather - 15°C (59°F) afternoons with zero humidity - makes cycling between Niseko's three sake breweries a pleasure, not a slog. The 15 km (9.3 mile) loop takes you past rice fields ready for harvest, and brewery staff have time to explain the process since summer tourists are gone. Each brewery offers different seasonal sake pressed from the new rice harvest.
October's cool mornings and warm afternoons create perfect onsen timing - the 42°C (108°F) water feels therapeutic against 8°C (46°F) air, but you won't overheat like in summer. Start with Yukichichibu at dawn (locals' favorite, opens 6 AM), then drive 20 minutes to Goshiki for the mountain views, finish at Kiranoyu where the outdoor pools overlook the remaining autumn colors. Weekday mornings have zero crowds.
October 1-20 is matsutake season, and licensed foraging tours take you to secret patches locals have used for generations. The mushrooms grow under larch trees at 800-1,200 m (2,625-3,937 ft) elevation, requiring a 2-hour hike through forests that smell like earth and pine. Each person finds 3-5 mushrooms typically, enough for a chef-prepared dinner featuring your personal harvest.
October's clear nights and new moon periods create perfect conditions for astrophotography - Lake Toya's reflections double the star count, and temperatures at 8°C (46°F) mean your camera batteries last twice as long as summer. The Milky Way is visible from 8 PM until 2 AM, with Mount Yotei silhouetted against star fields.
October Events & Festivals
What's happening during your visit
The valley's restaurants collaborate on a month-long festival where each creates special menus using October's harvest - wild mushrooms, mountain vegetables, and game. Pop-up stalls appear at Hirafu Village on weekends, and local chefs host cooking classes showing how to prepare seasonal ingredients. It's the only time you'll see these particular dishes.
