Condo turnover and a centenarian milestone sharpen Japan’s long-term picture
A national housing study shows concentrated short-term resale patterns, while Japan’s official centenarian tally passes 100,000 for the first time.
Developments
Two official releases look at Japan through very different time horizons. One tracks rapid turnover in parts of the condominium market; the other records the growing number of people who have lived for a century. Both are useful, but only within their carefully defined populations and dates.
1. MLIT finds short-term condominium resale concentrated in particular markets
MLIT analyzed about 570,000 new-condominium registrations and 1.5 million transfer registrations from 2018 through 2025 across the three major metropolitan regions and four regional cities. It defines short-term resale as a sale within one year of purchase and reports comparatively high or rising shares in parts of Tokyo, Kanagawa, Osaka and Hyogo. In Tokyo’s 23 wards in 2024, for units of at least 40 square meters, the share was 9.0% in buildings with at least 100 registrations and 2.9% elsewhere. These patterns do not describe every neighborhood or predict an individual buyer’s options, and an overseas address should not be interpreted as nationality. (Read the MLIT study)
2. Japan’s administrative count of centenarians passes 100,000
MHLW reports 107,677 centenarians, 7,914 more than a year earlier and the first total above 100,000. Women account for 94,298 of the tally and men for 13,379. The figures come from resident-registry reports as of September 1, with ages measured on September 15; the ministry separately says 54,294 people will reach 100 during fiscal 2026. The milestone is a demographic count, not a measure of health, independence or service availability, but it reinforces the scale of Japan’s long-term aging challenge. (Read the MHLW tally)
What residents should take away
National milestones and large transaction datasets can reveal structural pressures, but they do not replace local research. Housing decisions still depend on the specific building and market, while the practical effects of aging depend on household circumstances and municipal services.
