The development of infrastructures and a set of social facilities has been demanded recently to create wealthy and safe cities in Japan. Under this circumstance, a feasible and active use of underground space as a new frontier in the future is motivated, as it would be thought the best way to solve problems such as improvement of urban areas, concentration of metropolitan functions, tremendous uprising of land price, and the renewal of public utilities. Thinking back to the history of underground space use in Japan, it originates in the life in caves and the burial to tumuli in ancient times. Though some mining activities were seen in the 7th centuries, the underground had not been positively used for centuries. In the 17th and the 18th centuries, the underground facilities such as the water supply facility (Tokyo), the water tunnel (Hakone), and some other tunnels began to be constructed. In the 19th and the 20th century, the demand of the underground facilities has increased and a great number of tunnels have been constructed with advanced construction technology from foreign countries. Thus far, a variety of underground facilities are constructed such as tunnels, underground parkings, underground shopping malls, underground rivers, underground power plants, oil storage caverns and so on. However, many efforts were made to solve social and technical restrictions of the underground development in harmonizing with environment and land ownership. Various technical attentions have been drawn to stabilize the underground space and to control the underground water while excavating the underground space. Japan is mountainous country and most of the cities are located on the land of the alluvial formation. It has some seasons with a lot of rain, which keeps the groundwater table relatively high. Occurrence of earthquakes is also observed all around the country. Japan had to stand with these difficulties. The Japanese technology of excavating in the soft ground has been at the top level in the world, which allows proper underground construction in the densely inhabited city. For the further use of underground, we have to study the following subjects ; the concept of underground use in the urban development and advanced underground use, the systemization of underground space use, the regulation for underground development, safety and environmental conservation, and the psychological and mental effect of underground environment to the human being. In addition, the construction technology with the inventive and automated construction should also be developed to promote the underground use. キーワード（英）： - 記事区分： - 区分 　　　委員会論文集
