This tour visits Yasui Valley, where blue streams, waterfalls, and pools shine in the sunlight. Stroll riverside paths, breathe the fresh air, and enjoy the sound of flowing water.
Come and see why this “miracle clear stream” is one of Kochi’s most iconic destinations.

Nagoya Low-water Bridge
Nagoya Low-water Bridge
The Nagoya Low-water Bridge, or Nagoya Chinka-bashi, is a traditional low-water bridge crossing the Niyodo River.
Unlike modern bridges, the Nagoya Low-water Bridge offers a close, almost intimate connection with the river, allowing visitors to truly feel the harmony between human life and nature in Kochi.
Yasui Valley
Yasui Valley is one of the most stunning spots along the Niyodo River in central Kochi. Famous for its deep emerald-blue waters, it is considered one of the best places to experience the beauty of “Niyodo Blue.”
Crystal Basin (Suishō-buchi)&Sabō Dam (Check Dam)
Crystal Basin (Suishō-buchi)
The Crystal Basin, or Suishō-buchi, is one of the most iconic spots in Yasui Valley. Its name comes from the astonishing clarity of the water—so pure that the riverbed looks like polished crystal. The pool reflects sunlight in brilliant shades of blue and emerald, offering some of the clearest views of “Niyodo Blue.” Visitors often describe it as looking like liquid glass.
Sabō Dam (Check Dam)
Further upstream stands a sabō dam (erosion-control dam). While it was originally built for flood and sediment control, the calm water held back by the structure creates a mirror-like surface that beautifully reflects the surrounding forest. The contrast of man-made engineering with the untouched natural beauty highlights both the power and harmony of the landscape.

About Tour Guide Hiroshi M.
I’m a local licensed guide based in Kochi Prefecture. I grew up by the Pacific Ocean in Kochi and spent four years each in Tokyo and the United States—giving me both deep local knowledge and a global perspective.
Although I’m new to GoWithGuide, I’ve been welcoming international guests for years through my private rental villa in Aki City and as a local guide in Kochi. Working in the travel industry, I know not only the famous landmarks but also the hidden gems of the region.
All the photos you see here were taken by me—I enjoy photography, and if you’d like, I’d be happy to capture some memorable shots for you during the tour.

“Hidden gem”
We had a wonderful day with Hiroshi san. Our group of 5 was diverse; 2 seniors, 2 middle aged and 1 young person; everyone had fun, learned a lot and felt welcomed by Hiroshi san. Highly recommend to anyone if you stopping in Kochi ;

Thank you so much for taking the time to leave such a kind review! I really enjoyed spending the day with your group. It was wonderful to have guests of different ages all enjoying Kochi together, and I am so glad everyone had a good time. Also, I hope she continues to enjoy learning Japanese! Kochi is truly a hidden gem, and I hope you all carry a little piece of it with you and welcome you back someday! Arigato Gozaimashita. Hiroshi

“Great Day in Kochi”
We had booked the Kochi Highlights Tour with Hiroshi during our Diamond Princess cruise stop in Kochi. We had a full day starting with Kochi Castle, lunch at Hirome Market, strolling through the Obiyamachi shopping arcade, visiting the Chikurinji Temple and finishing with the Makino Botanical Garden. We had a wonderful day exploring the highlights of Kochi and were well taken care of by a local expert. Hiroshi was knowledgeable, attentive and patient, he introduced us to local dishes and the Konatsu fruit and took care in ensuring that my partner was able to enjoy a vegan meal at Hirome Market. We also made short stops at a local grocery store to pick up Inaka-zushi - countryside sushi - and at a gift shop that sold locally produced products. On top of all this, Hiroshi took amazing photos of us and provided a photographic perspective that on our own we would not be able to capture. We had a great memorable day and look forward to booking another tour with Hiroshi that next time we are in Kochi!
Hiroshi M.
Thank you so much for taking the time to leave such a wonderful review! It was a great pleasure guiding you both during your cruise stop. I am very happy to hear that you enjoyed our day exploring Kochi. It was a lot of fun introducing you to some of my favorite local flavors, and I am especially glad we found good vegan options for your partner at Hirome Market. Thank you also for your kind words about the photography. I always love taking photos to help my guests remember the day. I look forward to welcoming you back for another adventure the next time you are in Kochi. Safe travels! Warm regards, Hiroshi

“Perfect Guide for Kochi”
I cannot recommend Hiroshi more highly. His local knowledge of Kochi allowed us to see and do things we would not have been able to do on our own. We had a wonderful day in Kochi.
Hiroshi M.
Thank you so much for the wonderful review and the kind words. It was a real pleasure to spend the day with your family in Kochi, and I am so glad you enjoyed the experience. Kochi is still off the beaten path for many travelers, so I always try to share the small local stories and hidden details that make a visit here special. I am very happy that I could help you discover sides of the city that would be hard to find on your own. Cruise days in Kochi can feel short, but with good planning there is so much to enjoy. With a private guide and car, we can move at your own pace and add small local spots that are hard to reach on a group tour. Wishing you safe travels, and I would be delighted to welcome you back to Kochi anytime. Hiroshi
