What do Tokyo's most aging neighborhoods have in common
Tokyo’s 23 wards have as many as 15 city blocks that would be classed as ‘marginal villages’ due to their aging demographics. A marginal village is one where over 50% of the residents are over the age of 65.
The Asahi Shimbun newspaper used census data from 2020 to create a list of the oldest neighborhoods in Tokyo. Of the approximately 3,000 city blocks in the 23 wards, 15 are marginal villages.
