By conducting the questionnaire surveys among the inhabitants around high-rise buildings, we had already obtained the fact that the incidence ratios of wind environmental problems are highest at the zones nearest to the buildings. In this paper we report the results of the wind tunnel experiment which was made concerning the air flow around the scaled model of one of the surveyed areas to confirm our new hypothesis, "Ratios of wind environmental problems at the zone near to high-rise building become high because the wind speed at that zone is affected strongly by the construction of the building, and then the high wind speed increasing ratios are apt to appear". The conclusions are as follows; (1) Wind speed increasing areas where wind speed increase more than 10% by construction of buiding are apt to appear within the distance from the 2 times height of the building and seldom appear at the region farther than that distance; (2) Wind environmental problems are apt to take place at the wind speed increasing areas; (3) Distribution curves of the wind speed increasing ratios are almost similar to that of the wind problem incidence ratios.
