A Detailed Look at the Experience

Meeting Point and Departure

The tour begins at the Karuizawa Tourist Hall, conveniently located in the KyKaruizawa area, close to public transportation. From here, your guide will give a brief introduction before you head out on foot, setting the tone for a day of discovery. Starting at a well-known tourist information center ensures easy access and clear directions.

The Journey Begins: Former Nakayama Road to Sugahi Pass

The first part of your trek takes you past the Karuizawa inn, tracing the path of the historic Nakayama Road. The route is lined with remnants of old inns, giving a sense of stepping back in time. The walk is approximately 3 hours from the Usui Pass toward Sakamoto Hotel, covering significant historical ground as you descend from the mountain pass.

Along the way, you’ll encounter notable sites like the Yamanaka teahouse ruins, which hint at the area’s traditional hospitality roots. Travelers note that the route is both scenic and historically rich, with some reviewers mentioning that the views of the mountains are stunning, especially on clear days.

Stop 1: Former Usuitouge Viewpoint

One of the highlights is the viewpoint at Usui Pass, which offers a panoramic vista of the Kanto plains, and on clear days, the sight of Mt. Asama, Mt. Myogi, the Southern Alps, and Yatsugatake. Some lucky visitors have described the experience as breathtaking, with the possibility of seeing a sea of clouds spreading below.

This viewpoint is a perfect spot for photos and catching your breath before continuing the descent. The short, 10-minute stop is free and accessible, making it an easy addition to your itinerary.

Stop 2: Kumanokotai Shrine

Next, you visit the Kumanokotai Shrine, known as the best power spot in Karuizawa. It’s unique because it is a Shinto shrine located across a prefectural border, adding to its mystique. The shrine’s tranquil atmosphere offers a moment of reflection and cultural insight, and the short 10-minute visit is free of charge.

The Historic Descent: Usui Pass

The core of the tour is the descent from Usui Pass, historically regarded as one of the most challenging parts of the Nakasendo route. Walking along the historic sites and old pathways, you will gain a tangible sense of Japan’s ancient travel routes.

The walk takes about 3 hours, during which your guide will point out notable features and share stories about the pass’s reputation. This segment is physically demanding but rewarding, especially for those interested in Japan’s old transportation routes. Reviewers have quoted that the walk through this section is “both scenic and steep, with a sense of stepping into history.”

Stop 3: Sakamoto Shuku

Arriving at Sakamoto Inn, you’ll see the long, narrow irrigation moats that have been carefully restored, evoking the look and feel of the past. Historically, Sakamoto Inn was a prosperous lodging place that outpaced Nakayama-do’s more famous inn, thanks to its strategic location and size.

Your brief visit here offers a glimpse into Japan’s past hospitality and infrastructure. Some reviewers appreciated the restored irrigation moats as a charming detail, adding authenticity to the experience.

Ending at Yokokawa Station and the Hot Spring

After finishing the trek, the tour offers a relaxing visit to the Kotonoyu hot springs, where you can bathe slowly and unwind after your exertion. Travelers often highlight this as a perfect way to conclude the day, especially given the stunning mountain views from the hot spring baths.

If you’re returning to Karuizawa, a bus service is available, making the logistics straightforward. The convenience of the return transportation is a thoughtful touch, especially after a full day of walking.

The Value of the Tour

At $91 per person, this experience offers a rich combination of history, scenery, and relaxation. The price includes expert guidance, access to cultural sites, and the hot springs, which altogether make it a solid value for an immersive half-day journey.

Compared to the cost of hiring a private guide or exploring independently, this guided tour ensures you won’t miss any hidden stories or viewpoints. The small-group setting (not explicitly specified but implied by the private tour note) also enhances the overall experience, allowing for personalized interactions and questions.
