Shiga Kogen Larch Autumn Colors Hike: Beyond Maruike Pond

TL;DR: Walk the Hasuike and Kidoike areas in late September to mid-October, then drop down to Yudanaka or Shibu Onsen for an evening soak.

The best Shiga Kogen larch autumn colors hike beyond Maruike Pond links the Hasuike and Kidoike areas with stretches along the Shiga-Kusatsu Highway, where larch and birch turn first at the highest elevations. Peak color moves downhill through October, so you can chase it just by picking your elevation. Then you finish in hot water in Yudanaka or Shibu Onsen.

I'll be honest: I used to think autumn in Shiga Kogen meant one thing, a quick look at Maruike and back to the bus. I was wrong. A guest at our Tokyo Airbnb once asked me for a snow-monkey-and-Shiga-Kogen plan, and it made me realise how much visitors want a real itinerary rather than a single photo stop. So here's the one I'd give a friend.

When is the best time to see autumn colors in Shiga Kogen?

Late September to early October is typical for the highest areas, with color working its way down to lower slopes and the valley towns by late October. Exact timing shifts with summer heat and the first cold snaps, so treat these windows as rough guides, not promises.

Shiga Kogen sits roughly between 1,300 and 2,300 meters, and that elevation gap is the whole trick. When the high ridges are already past their best, Yudanaka down in the valley is often just getting started. Check recent local reports a few days before you go.

Where should I hike beyond Maruike Pond?

Start with Hasuike and Kidoike, then add short walks off the Shiga-Kusatsu Highway where larch stands line the road. You get the same gold-and-water scenery with noticeably fewer people at midday, at least in my experience.

1. Hasuike area: Gentle paths near the water make this an easy first stop, good for families. Plan about an hour for a relaxed loop.
2. Kidoike area: Quieter and more forested. Go early if you want still water and clear reflections.
3. Maruike Pond: Still worth a look, especially in the quiet first hour. Just don't make it your only stop.
4. Shiga-Kusatsu Highway corridor: Pull-offs and short walks where larch and birch glow in low sun. Drive carefully; it's a mountain road.

Shiga Kogen is big, and its trails aren't all signposted the same way, so I'd download an offline map and check trail status at a visitor center first. Bears live in these mountains, so carry a bell and skip solo wandering at dawn.

How do I get to Shiga Kogen trailheads by bus or car?

There's no shinkansen to Shiga Kogen: take the Hokuriku Shinkansen to Nagano, then the Nagaden train to Yudanaka, then a local bus up. Nagano to Yudanaka takes roughly 45 minutes by train, and the bus to the Shiga Kogen base is a further stretch, so allow a full morning from Tokyo.

• By bus: Direct buses also run from Nagano Station. Confirm the autumn timetable, since services thin out after summer.
• By car: Route 292 is the usual road in. I learned the hard way in early November that 冬季閉鎖 (winter closure) is real: I reached a closed gate at 5pm. Shiga Kogen access isn't year-round access.
• Parking: Fill up early on peak color weekends.

What should I pack for cold autumn mornings in Shiga Kogen?

Pack layers: a warm mid-layer, a windproof shell, gloves and a hat, even when the valley feels mild. Mornings at altitude can drop close to freezing in early October, while afternoons warm up fast.

• Thermal base layer and fleece
• Light waterproof jacket
• Gloves and a beanie
• Sturdy walking shoes with grip, since leaves on wet boardwalks are slippery
• Bear bell, water, and snacks
• A small towel for the onsen later

How can I combine a foliage hike with an onsen stay in Yudanaka or Shibu Onsen?

Hike in the morning, ride the bus down, and soak in Shibu Onsen or Yudanaka by late afternoon. Staying in the valley also gives you cheaper, easier lodging than the resort area, and the heat feels like a real reward after a cold ridge walk.

My favorite moment is walking Shibu's stone lanes in a yukata. I did the nine outer baths in February once, and by the eighth stop my feet were warmer than my face. In autumn it's gentler, with cooler evenings and the smell of wood smoke. Many ryokan serve dinner courses, and staff are usually happy to explain which baths are open to guests. Book early for peak foliage weekends.

Yudanaka is more convenient by train, and Shibu is the one for atmosphere. If you have an extra morning, the Jigokudani Snow Monkey Park is nearby via Kanbayashi Onsen, though the monkeys are most famous in winter.

When does winter 2026-27 lift and bus information usually come out?

Winter lift pass prices and bus timetables for the season usually appear from autumn into early winter, so check official sites in October and November. I can't confirm 2026-27 dates yet, and they vary by operator, so don't book around guesses.

If you're planning a ski trip, bookmark the official Shiga Kogen resort page and your bus operator's page now. Dates and fares can change, so verify before paying for non-refundable lodging.
