The feature of overhead transmission lines in Japan is that in many cases, there are severe construction conditions, such as narrow flat-ground and steep mountain ground. This is because the country is narrow and also interest in the environment is increasing. In these conditions, Japan has examined various foundations for overhead transmission lines. This paper describes the features of foundation type, design method and investigation results of power line tower foundations in Japan.
