Sota Adachi is a Research Fellow at the Japan Society for the Promotion of Science (JSPS) and a Ph.D. candidate. His specialty is architectural planning and design with a specific research interest in how towns, architecture, and communities support the needs of various groups with often contradicting needs in a shrinking society.

He is exploring diverse shrinking processes in former coal mining cites of Japan, one of most aged countries in the world. Coal mining cities have experienced sharp depopulation and aging following the decline of the industry and the end of coal mining as a result of the energy revolution of the 1960s.

Through his research, he seeks to establish strategies for managing needs of the super-aged and address the population decline in Japanese society by creating sustainable residential areas where people of all ages have adequate and appropriate access to housing.
