“…To summarize, the Japanese government nowadays prioritizes a reduced number of locations through an assumed transit‐oriented development policy while trying, at the same time, to manage a gradual de‐intensification of land use by letting vacant lots accumulate outside of designated areas (Yamagata and Maruyame 2016). Yet, those processes started to appear before the policies, with for example Kim, Onishi, and Suga (2007) noticing that in the last decades of the 20th century, disurbanization and reurbanization were increasing and co‐occurring. The hypothesis is that hard shell — soft yolk neighborhoods, now mostly located in‐between the central places and the far outlying areas, are slowly mutating.…”

As cities adapt to new needs and challenges, their forms change in close relation to population dynamics. This article focuses on the link between population dynamics and the evolution of building hull types. The case study is the Osaka‐Kobe city‐region in Japan, a country globally witnessing an intense population decline. Morphometric indicators are coupled with a tree‐like classificatory model in order to label buildings into consistent classes between two different periods (2003–2004 and 2013–2014). The building class distributions and their evolutions are studied in conjunction with population censuses. Urban adaptation processes are particularly accounted for through the study of the replacement of building types. Results show that, among other things, townhouses in traditional neighborhoods are gradually being replaced by small‐size collective complexes. In far outlying areas, people are still eager to move and live in detached single‐family homes despite a global context of population decline. Finally, central places are increasingly filled by narrow almost‐adjoining towers. Relations between building types and population dynamics, detailed through maps and statistics, show that peoples are increasingly concentrating in central locations associated with specific building types, while some other peripheral locations are concerned by both a disappearance of specific building types and a population decline.
