Yamakoshi region of Nagaoka-city is a famous for breeding Nishikigoi and has beautiful landscapes of pond terraces. This study investigated the comparison of rice terraces and pond terraces. Objective (1.) process of changing rice production to breeding NIshikigoi (2.) differences of structures (3.) changing the landscape. (1.) A process of changing: Change by turning small pond into large ones, because of being constructed by hand at the beginning. Breeding Nishikigoi is a high-risk business. Large size rice terraces were kept efficient by the use of machines during rice farming. (2) Differences of structures: Ponds are deeper than rice terraces and have gradual inside walls. Ponds have wide field side passes, and shapes on the insides are rounded for Nishikigoi to swim easily. (3) Changing of Landscape: Many ponds are characteristic of the landscape. Pond terraces make water landscapes without vegetation in the summertime. Deep shaped ponds' edges makes for an expressive snow landscape. Conclusion: Most of the landscapes in this area are harmonious with each other, by changing to pond terraces from rice terraces did not resist the natural landform and symbiosis with the environment. In this case showing the way to landscaping in mountainous farming villages in part of Japan's future.
