The Early Morning Tour — own the valley before breakfast.
At seven in the morning the post town belongs to the residents, the river mist, and you. This is a slow two-hour guided loop through Nagiso's lanes and riverside roads in the softest light of the day — and you're back by nine, in time for breakfast and checkout. The easiest way to try a guided ride, and the prettiest two hours on this whole site.

The Kiso River Downhill — the most comfortable 50 km in the world.
48.9 km, Yabuhara-juku to Nagiso Station, almost all of it downhill. You set off high in the valley, near the headwaters of the Kiso River, and follow the water as it grows from a mountain stream into a full river — rolling past seven of the Kiso road's old post towns (from Yabuhara down to Midono) on one long and gentle descent. Breakfast in Yabuhara, lunch in Kiso-Fukushima, a coffee stop at Nojiri Station, and a finish line at Nagiso as the light goes long. Every metre has been ridden and re-ridden by a local guide to find the most beautiful, the most comfortable, and the safest line down the valley — and two guides ride with every group, one setting the line up front and one sweeping at the back.

Before you commit
Can I ride this one self-guided?
No — this course is guided only. In a few places, one wrong turn drops you onto roads with heavy traffic. To keep the day safe, two guides ride the whole route with you — one up front, one at the back.
I'm not sure I can ride 50+ km.
Nearly 50 km sounds like an expert distance, we know. But it's gentle downhill almost the entire way, and on the few uphill stretches the high-powered e-bike does the climbing for you. If you can ride a normal bike 10 km on flat ground, you'll reach the finish smiling. This is your chance to surprise yourself.
Can I bail out partway?
Yes. The route shadows the JR line the whole way, so if you're not feeling well you can step off and take a train from the nearest station. Just lock the bike at the station rack and we'll collect it afterwards.
What happens in bad weather?
Rain or snow means we cancel and refund by default. Our e-bikes handle rough conditions well, though — so if it's light enough not to affect safety or the experience, and everyone's happy to ride, we may still run it. If the weather turns mid-ride, we stop there, refund part of the fee, and take the train to the finish.
What about bears?
Like everywhere in these mountains, the Kiso has Asiatic black bears. We hand you a bear bell and bear spray to carry, your lead guide always rides up front, and we run through a what-to-do-if-you-meet-one briefing before we set off.
How do you handle summer heat and winter cold?
In summer we lend you a rashguard, keep you dousing with water, and break to dip in the valley's river pools. In winter we lend cold-weather gear and stop at footbaths and onsen along the way to warm back up.
Out here, your guide is the first responder — and Yakkun's trained for it.
Yakkun is certified in Wilderness First Aid by Wilderness Medical Associates International — the same training that expedition crews and mountain-rescue teams rely on. Deep in the valley an ambulance can be a long way off, so he's trained to be the help until it arrives.
- Adult CPR and AED use
- Clearing an obstructed airway
- Controlling severe bleeding (hemorrhage control)
