Discovering the Rivers of Yamanashi: A Detailed Look

We found this rafting tour to be a well-rounded offering for anyone eager to combine adventure with culture. Starting at the Honryudo base, the experience kicks off with a safety briefing and a chance to pick out your rafting clothes. The guide, whose calm and clear instructions set the tone, makes sure everyone feels confident before heading to the river.
The Rivers themselves are the stars of the show. The Hayakawa River (Hayakawa) is a charming river flowing through Hakone and Odawara — a gentle yet lively introduction to Japan’s rushing waterways. The Fujikawa (Fuji River) is one of Japan’s swiftest, stretching 128 kilometers through Yamanashi and Shizuoka. Its reputation as one of the top three rapid rivers indicates a good level of excitement, especially for those with some rafting experience or a desire to test their skills.
The two-hour rafting segment provides just enough time to get your adrenaline pumping and your senses alert. We loved the way the guide kept us engaged, pointing out surrounding flora and geological features, making it more than just a splashy ride. The experience is physically invigorating but not overly strenuous, making it accessible for most participants with moderate fitness levels.
What makes this tour special is how it combines the thrill of white-water rafting with educational moments. You’ll learn about the history and unique features of these rivers, which adds depth to an already memorable outing. And the scenery? Expect lush greenery, rugged riverbanks, and the occasional sighting of local wildlife, making each rapid and stretch of calm water visually rewarding.
After the ride, you’ll return to the base, where the tour includes a free onsen bath at the Shimobe Hotel. This simple yet authentic Japanese experience allows you to unwind, soothe your muscles, and reflect on your adventure. The hotel’s sento (public bath) is an excellent way to relax after your physical exertion, and it’s a popular finishing touch appreciated by many travelers.
What to Expect: Day-by-Day Breakdown
Meeting at Honryudo Base is straightforward; arrive 10 minutes early for check-in and gear allocation. If you don’t have a car, a pickup service from Shimobe Onsen Station can be arranged, which is a thoughtful touch for travelers staying locally.
Once everyone is suited up, your guide will lead a brief safety orientation. This is crucial, especially if you’re unfamiliar with river rafting, but the instructions are clear and designed to keep everyone safe and confident. The clothes and gear are available in multiple sizes, ensuring comfort.
The start point is a short drive or walk away, where your group begins the two-hour rafting adventure. The actual ride involves navigating rapids and calmer stretches, giving you a taste of Japan’s powerful waterways. The guide’s commentary brings the experience alive, pointing out natural features and explaining the rivers’ histories.
Throughout the trip, you’ll be encouraged to participate actively—paddle, listen, and enjoy the scenery. The group size keeps it intimate, fostering camaraderie and personalized attention.
At 12:30, you’ll head back to the base for a quick change, then make your way to the Shimobe Hotel for your included bath. Present your reservation screen at the front desk — easy and stress-free.
The Practical Side: Costs, Group Size, and Booking

Pricing at $65.34 per person offers notably good value, considering the guide, equipment, insurance, and the included onsen bath. The small group format ensures you won’t feel lost in a crowd, and the booking window of about 90 days helps you plan ahead.

Authenticity and the Experience Value

What we appreciated most is how the tour balances thrill and tranquility. The scenic rivers are a highlight, offering a glimpse into Japan’s natural landscape that you might not encounter on more traditional sightseeing tours. The on-the-water experience is thrilling but safe, thanks to the professional guidance and safety equipment.
The on-site safety instructions and equipment rental are thoughtfully organized, ensuring beginners don’t feel out of place. The small size of the tour group fosters a friendly atmosphere, allowing for more personalized interaction and a better overall experience.
On top of that, finishing with a public onsen bath adds an authentic Japanese touch — after all, what better way to soothe sore muscles and enjoy Japanese culture than a traditional hot bath? It’s a simple, yet effective way to round out the day.
