A breathtaking dam infrastructure tour that takes you to areas not open to the public, guided by an expert.
[Highlights] This is an experiential infrastructure tour of the Nukui Dam, one of the largest arch dams in Western Japan, where you'll explore areas not normally open to the public with a guide.
You'll climb the catwalk and experience the roaring water cascading down from directly beneath the gates up close. You'll also get access to the right bank, a viewing area exclusively open to this tour, to watch the water release. If weather conditions are right, there's a high probability of seeing a rainbow over the water release – another highlight.
The right bank is easily accessible by car, allowing for a more comfortable and less crowded viewing experience. Through the guide's explanations, you'll enjoy both the awe-inspiring spectacle and a sense of learning.
