FORMATION OF UNDERGROUND PUBLIC SPACE IN LARGE CITIES, BY THE EXAMPLE OF SAPPORO, JAPAN

Rapid economic growth and the high urbanization of large cities in Japan
increase the need for more new public spaces. In these conditions, a special solution is the
further development of underground spaces, which is actively supported by the Japanese
government [1]. Moreover, a more systematic approach to the design of these spaces, to
improve their quality to obtain a more comfortable and rich urban environment. This article
presents a study of an underground street in Sapporo, Japan, the impact of events held here (art
exhibitions, various festivals and political performances) on the activity and interaction of a
person with an underground urban environment. The results show that the activity of
pedestrians of the underground street, compared with the days ―free‖ from any events, increases
by 84%, visitors begin to communicate more with each other, the number of parents with
children increased by 73% and people by 83% disabled. This confirms the importance of using
underground territories for conducting ―event‖ events, including them in the design of urban
underground spaces, especially in ―winter‖ cities, to increase attendance and residents’ activity
