Mapping Japan's Declining Population

Japan’s population is aging and declining. Japanese people are living longer and having fewer children and later in life. By 2060 the Japanese government are predicting that over half the population will be over 65.

This Japanese Population Map visualizes the 2040 population predictions for every Japanese prefecture. Using the map you can explore the population predictions for the number of young females and a breakdown of the overall population by age group.

Prefectures that are predicted to grow in population are shown in green and prefectures that are expected to decline are shown in red. If you zoom out on the map you can see that the population is expected to decline across nearly the whole country.

You can use the city links at the bottom of the map to quickly zoom in on Japan's biggest cities. You can then click on individual prefectures on the map to view the predicted population of females aged 20-39 in 2040. You can also view a breakdown of the predicted population in the selected prefecture by age group.
