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.

“Our Excellent Adventure in Kochi With Hiroshi ”
We were impressed with our tour guided by Hiroshi. He was very knowledgeable and patient with our group. His grasp of English was very good. The tour provided our group with a great introduction to Kochi and well worth our time. It was a pleasure to be sooo comfortable in the van that was used for the tour!

Thank you very much for your kind review! I really enjoyed the tour with your group. You already knew a lot about Japanese history, and you were also very interested in the history of Kochi, so I was happy to share many stories with you. I am also glad you felt comfortable in the van as we moved between each place. I hope you have wonderful memories of Kochi, and I would love to welcome you back in different seasons!

“Very Flexible Guide”
Our group was hoping for a different itinerary, after having several days of visiting wonderful shrines and temples in several other ports. Hiroshi arranged for the group to experience the making of Washi paper, a very traditional Japanese tradition. While the paper was drying at the shop, the group did some local touring and eating, which everyone enjoyed. Hiroshi speaks excellent English and made our day fun and memorable.
Hiroshi M.
Thank you very much for taking the time to write this wonderful review. One of the best things about having a private local guide is that the plan can change to match what guests want on the day. As someone born and raised in Kochi, I was happy to use my local knowledge and experience to make your day special. It is truly an honor to hear that everyone enjoyed it. I hope you will come back to Kochi again someday.

“A Fantastic Day in Kochi with Hiroshi—Local Flavors and Thoughtful Extras!”
We had a wonderful day exploring Kochi with Hiroshi! We hired him with a car service, which made traveling between sights comfortable and easy and allowed us to experience so much in one day. He was knowledgeable, easy to understand, and shared interesting information about Kochi, its history, and local culture throughout our tour. We explored Ryugado Cave, a beautiful limestone cave and a welcome cool break from the heat. At Tosa Tsubohachiya, we saw knives hand-forged by local craftsmen. We also visited Kochi Castle, one of Japan’s few original castles, where we climbed the steep stairs all the way to the top! A particular highlight was Hirome Market. Hiroshi’s authentic food recommendations made lunch an experience we will always remember. We enjoyed crispy Yasubei gyoza, Tosa wagyu, seared bonito with salt and with sauce, bonito sashimi, aosa nori tempura, and fresh fruit. We also sampled local Keigetsu sake. It was an incredible introduction to Kochi’s local flavors, and we appreciated having his guidance on what to try. An especially thoughtful touch was that Hiroshi brought a professional camera and photographed our group throughout the day. He shared a Google photo album with us that same day! It was incredibly generous and so nice to have beautiful memories with all of us in the pictures. Hiroshi made our day enjoyable, informative, and memorable. The combination of fascinating sights, delicious local food, comfortable transportation, and his thoughtful approach made this a wonderful tour. We’re so glad we hired him and would highly recommend him to anyone visiting Kochi!

Thank you so much for this wonderful review! It was a real pleasure to spend the day with your group of five. September in Kochi can still be very hot, so I am glad Ryugado Cave was a nice cool start to the day. It was also great to see you all climb the steep stairs to the top of Kochi Castle. The view from there is always worth it! Hirome Market is one of my favorite places to share with guests. Katsuo no tataki with salt and with sauce, Yasubei gyoza, Tosa wagyu, and local sake are all things I really want visitors to try. I am happy the food became such a special memory for you. Taking photos during the tour is my small gift to every guest. I want you to enjoy the moment without worrying about the camera, and I am glad you liked having everyone in the pictures together. Thank you again for choosing to explore Kochi with me. I hope you enjoyed the rest of your cruise around Japan, and I would love to welcome you back to Kochi someday!
