Old Nakasendo trekking from Karuizawa-Beyond Sugahi Pass to Sakamoto Hotel-

Exploring the Old Nakasendo from Karuizawa to Yokogawa: A Trek Through History and Nature

If you’re looking for a day that combines history, stunning scenery, and culture, this Old Nakasendo trekking tour from Karuizawa is an appealing choice. For around $91 per person, you’ll spend approximately 5 to 6 hours walking through historic routes, stopping at scenic viewpoints, power spots, and ending with a relaxing soak in a hot spring. What makes this experience stand out is the chance to stroll along the ancient Nakasendo route, once a vital corridor connecting Edo (Tokyo) with Kyoto, and to enjoy views that stretch across the Kanto plains.

Two things we particularly liked about this tour are the panoramic views from Usui Pass—where Mt. Asama and the Yatsugatake mountains often seem close enough to touch—and the visit to the Kumanokotai Shrine, which is not only a power spot but also a rare site crossing prefectural borders. The hot spring “Kotonoyu” at the end is a perfect way to unwind after a day of walking.

One possible consideration is the moderate physical fitness requirement; the tour involves a significant walk, including some steep descent at Usui Pass. If you’re not used to hiking or have mobility issues, it’s worth considering. This experience is ideal for those who enjoy outdoor walks, scenic views, and cultural history, particularly travelers eager to walk a stretch of Japan’s historic trail at a comfortable pace.

A Full Breakdown of the Nakasendo Trekking Experience

Starting Point: Karuizawa Tourist Hall

Our journey begins at the Karuizawa Tourist Hall, conveniently located in the KyKaruizawa area. From here, you’ll meet your guide and set off on a route that promises both physical activity and cultural discovery. The initial walk is a gentle introduction, passing through the charming streets of Karuizawa, a popular resort town known for its cool climate and lush scenery.

Stop 1: Former Usuitouge Viewpoint

Within about ten minutes, you’ll arrive at the Former Usuitouge Viewpoint. If the weather is clear, this spot offers a spectacular panorama: on a good day, you can see Mt. Asama, the Mt. Myogi mountain range, and even stretch your gaze to the Southern Alps and Yatsugatake. Travelers have noted that on sunny days, the sea of clouds below creates a surreal landscape, making it a perfect photo opportunity. Best of all, entry is free, which adds to the value of this scenic stop.

Stop 2: Kumanokotai Shrine

Next, in about ten minutes, you’ll visit the Kumanokotai Shrine—a power spot revered for its spiritual significance. Unique in that it straddles the border between Nagano and Gunma prefectures, this shrine offers a peaceful environment where you can soak in the spiritual atmosphere. Visitors often mention its rare location crossing borders and its serene environment made even more special by the natural surroundings.

Stop 3: The Historic Usui Pass

The core of the day is the long descent at Usui Pass, which takes roughly three hours. This part of the trek is where you truly walk the path that once connected Edo to Kyoto—the challenging section of Nakasendo. The route is lined with historic markers and sites that tell stories of Japan’s past travelers. The descent is steep but manageable, and the views on the way down are spectacular and full of history.

Stop 4: Sakamoto Shuku and Inn

As you arrive at Sakamoto inn, you’ll see it was once a bustling lodging place that outgrew its neighbor, Nakayama-do. Its restored irrigation moats evoke the atmosphere of old Japan, and the inn itself offers a glimpse into the past. Travelers describe the area as quiet but evocative, providing a tangible sense of what it was like to travel those rugged routes.

End of Trek: Sakamoto Hotel and Hot Springs

The tour wraps up with a visit to the peaceful Kotonoyu hot spring. Here, you can bathe leisurely, allowing your tired muscles to relax while enjoying the tranquil setting. It’s a perfect finish before heading back—whether you’re returning to Karuizawa or heading to Yokogawa Station—via the provided bus service.

The Journey’s Practicalities and Value

The cost of $91 covers not only the guided trek but also the convenience of private group experiences and mobile tickets, making it easier to manage. The duration of about 5-6 hours strikes a good balance—enough time to enjoy the scenery and stops without feeling rushed. The moderate physical activity involved means it’s suitable for most travelers with decent fitness levels, but those with mobility issues may want to prepare accordingly.

We appreciated that the tour is private, catering solely to your group, which means the pace and focus can adapt to your interests. The near public transportation access at the start and end ensures that getting to and from the tour is straightforward.

The weather-dependent nature of the experience is worth noting—clear days promise the best views, especially at the viewpoint—and a full refund is available if conditions are poor or if you cancel at least 24 hours ahead.
