A 64m high, elevator-type fishway was constructed at the Komaki Dam on the Sho River in Toyama Prefecture which was completed in 1929. Although highly effective in the early years after construction, the influence of the Soyama Dam which was built upstream and the development of the fish breeding industry led to the decline of dependence on the fishway and in 1943 it was converted into harbor equipment. This paper studies the evaluation of the Komaki Dam fishway and the social and technical background against which it was judged to be inflective and was removed.
