It is estimated that the population of Tokyo will be aging rapidly in the near future. In aging society, the concentration of urban functions around stations is required, especially in Tokyo Metropolis where a network of railroads has been spread. On the other hand, Tokyo has witnessed population grown in the era of urban core revival. So it is inferred that population expand into the districts which are far from station. This paper aims to clarify the living environments of the population-increasing districts out of station catchment area in Tokyo Metropolis. The results are the following :<br> <b>1) The relation between population movement and distance from station in recent years.</b><br> In Tokyo Metropolis, the population is increasing continuously since 2000 due to under the era of urban core revival. Analyze by distance from station, there are many districts where population had increased for three successive periods since 2000 (Study districts), in spite of the fact that the station is more than 1 km away. This trend goes against the concentration of urban functions around stations.<br> <b>2) The change of residential structure caused by increase in population in districts out of station catchment area.</b><br> In general, a lot of middle-aged (34-50) parenting families live in study districts. The population structure wasn’t balanced in 2000, for example, mature-aged (50-64) families or young (20-34) single-person households was the main household type in some study districts. However, the alternation of generation and the mixture of family types are happening in many study districts because middle-aged families are flowing in. Households living in owned houses are increasing and it seems that people are coming to study districts to get places of residence for a long time in the era of urban core revival.<br> <b>3) The living environments classified according to change of residential structure in districts out of station catchment area.</b><br> Land prices and population densities are low in study districts because stations are far away from there. Although, there aren't much difference in indices such as land prices and population densities between study districts and other districts out of station catchment area in the same city, the lands like agricultural lands, industrial lands or unused lands which have room for development in these districts are larger than other districts. By developing these lands for housing, population is growing. Regarding regional amenities received by residents, many study districts are close to arterial roads and elementary schools, but the bus usability is not good, and the commercial environments of these districts are inferior to that of other districts out of station catchment area in the same city.
