In Tokyo, super-high-rise housings have been rapidly increasing since 2000. We studied 99 housings which were built 1989-2011 with over 100m high. In early time, in relatively larger sites 1 to 3 residential buildings were built with mid-rises ones and other facilities. In recent years, in small sites 1 or 2 ones are often built without mid-rises and other regional facilities. In these cases one residential building is built parallel to the frontal street so that its floor area ratio becomes maximum. Its building coverage ratio of high-rise part is about 20~45%.
