Hokkaido · Early Autumn
Ginsendai is one of the first places in Japan to show real autumn colour: a trailhead at 1,517 m on the eastern flank of Daisetsuzan, where the slopes above turn crimson from mid-September. For 2026 the access rules are already announced — vehicle access is controlled September 12–23, with a reserved charter bus from Sounkyo and a limited number of advance-reservation car slots. Below: how the access system works, what the official route involves, and how to build a day around it.
Why Ginsendai, specifically
Daisetsuzan has three main autumn gateways — the Asahidake ropeway, the Kurodake ropeway from Sounkyo, and Ginsendai — and I compared all three in my Daisetsuzan September guide. Ginsendai’s claim is simple: it is the road-accessible point where autumn colour is at its most concentrated, with rowan-red slopes visible without committing to a summit day. Kamikawa Town’s own course map puts the first flower garden — the classic viewpoint — at 1.3 km and about an hour from the trailhead, and Mt. Akadake’s summit at 4.3 km and about three hours one way.
How the 2026 access actually works
| When | How you get up | Notes |
|---|---|---|
| Before Sep 12 | Own car or taxi on the Ginsendai forest road | No control yet; the road is mountain-grade gravel in sections |
| Sep 12–23 (control period) | Reserved charter bus from the Sounkyo information centre, or an advance-reserved private-car slot (alternating traffic) | ¥2,500 one way / ¥5,000 return; reservations open around mid-August via Kamikawa Town’s announced channels |
| After Sep 23 | Own cars scheduled to be allowed again from 16:30 on Sep 23 | Subject to weather — early winter closures happen at this elevation |
The control exists because the window is short and the mountain road is narrow — it replaces the congestion that used to be managed ad hoc. Note the gate closes from 19:00 on September 11, and buses carry about 40 seats each: booking early matters, and it is worth rechecking the town’s page just before travel.
On the trail
The Akadake trail leaves straight from the trailhead, and hikers sign the register at the Ginsendai patrol office before entering. You do not need to summit anything: there are views near the trailhead, and the first flower garden at 1.3 km / ~1 hour is where the celebrated colour opens up — but be clear that this is a graded alpine hiking trail (Kamikawa Town rates it Daisetsuzan grade 2–3), not a park path. Minimum kit per the park’s safety guidance: hiking footwear, full rainwear, warm layers, gloves and hat, headlamp, map, and a bear bell — bear spray is recommended. Weather turns fast at this elevation. If the forecast is poor, check Kurodake Ropeway operations back in Sounkyo as a lower-commitment alternative that colours up in the same weeks.
Building the day
Stay in Sounkyo Onsen the night before — the 2026 charter bus is scheduled to leave from in front of the Sounkyo Information Center, and an evening walk in the gorge pairs well with the stay. From Asahikawa, Sounkyo is about 110 minutes by Dohoku Bus; from Sapporo it is a long half-day of travel, which is why I would not attempt Ginsendai as a Sapporo day trip in the control period. For Sounkyo Onsen, compare availability on Booking.com or Agoda; if you need an Asahikawa transit night, Trip.com covers the station-area business hotels. Choose refundable rates until your access reservation is confirmed.
Peak colour varies with each year’s cold snaps. Check our live koyo tracker from early September — the Hokkaido row switches to forecast and report data as the season starts — and pick a weekday slot if you can; weekends fill first.

FAQ
Do I need to reserve to visit Ginsendai in 2026?
Between September 12 and 23, yes — either a seat on the reserved charter bus from Sounkyo (¥2,500 one way, ¥5,000 return) or one of the limited advance-reservation private-car slots. Outside those dates the forest road is open to private vehicles as usual. Reservations open around mid-August.
How hard is the walk from the Ginsendai trailhead?
It is a graded alpine hiking trail, not a stroll: the first flower garden viewpoint is about 1.3 km and one hour uphill from the 1,517 m trailhead, and Kamikawa Town rates the route Daisetsuzan grade 2–3. Hiking footwear, rainwear and warm layers are the minimum. Mt. Akadake’s summit is 4.3 km / about 3 hours one way — a proper half-day objective.
Is Ginsendai better than the Asahidake or Kurodake ropeways?
They serve different trips. The ropeways lift you to the alpine zone with no walking commitment and run in most weather; Ginsendai gives you the most concentrated roadside-access colour but asks for a real (if short) walk and a reservation in peak weeks. My Daisetsuzan guide compares all three gateways in detail.
What about bears?
Daisetsuzan is brown-bear country and Ginsendai is no exception. Carry a bell, make noise on quiet stretches, and check the latest bear notices and trailhead postings before entering — routes can change or close after sightings. Sign the hikers’ register at the Ginsendai patrol office; the nearby Kogen Onsen pond course goes further with a mandatory bear lecture.
Can I visit Ginsendai without a car?
During the September 12–23 control period, yes — that is exactly what the reserved charter bus from Sounkyo is for. Outside those dates there is no regular year-round public bus up the forest road (a separate summer weekend shuttle ran only through September 6 in 2026), so you would need a car or taxi from Sounkyo.
