Non-residential building floor area in Tokyo 2022, by ward and construction year
As of January 2022, most of the floor area of non-residential buildings in Tokyo's 23 wards was located in Minato ward at more than 22.4 million square meters, followed by Chiyoda at over 21 million square meters. While the vast majority of remaining building floor space that was constructed before the 1990s can be found in Chiyoda, Minato was the ward with the largest floor area of non-residential buildings built from 2000 onwards. Together with Chuo, Minato and Chiyoda are the only three wards in all of Tokyo in which the commercially used floor area of buildings surpasses the residentially used area.
