The Population of Tokyo has increased for 21 years

As of January 1, 2017, 121,583,658 people live in Japan (announced on July 5, Ministry of Internal Affairs). This figure has recorded a decline for eight consecutive years, and it is believed that the population of Japan will not increase in the future.


Baby boom generation ages

After the end of the Second World War, the baby boom came to Japan as well as the countries around the world. The baby boomer generation has reached 70 years old, and Japan has entered a serious aging society with fewer children. Over 25% of the population of Japan is over 65 years old, and this ratio will continue to increase.

By 2020, around the time of the Tokyo Olympics being held, the aging rate is expected to reach 30%, Japan will become a country with only old people. Particularly, this trend is remarkable in local cities. Young people find employment in urban areas and there are many places where only old people remain in the area.

There are more than 100 municipalities of old people who are over 65 years old already over 40% of the population. These municipalities are expected to disappear in about another 20 years.

The population of Tokyo continues to increase

As the population of Japan as a whole and the population of local cities are decreasing, the population of Tokyo continues to increase. It is because the number of people living in Tokyo is increasing, leaving local cities that have become difficult to live in.


The population has decreased, the railroads have been abolished, the shops are closed, and the population is still draining out of the vibrant areas. The destinations are in Tokyo. The population of Tokyo has exceeded 13 million, reaching more than 10% of the population of Japan.

But population concentration in Tokyo creates many problems. The improvement of housing environment and educational environment has not kept pace. The rent in Tokyo is expensive, and it is very difficult to keep children in nursery school.

The bias of age and area makes the population problem more serious.
