The Total Population

First of all, what is the population of Japan?

The Total Population, as of 2023, is 123.3 million people, which ranks 12th in the world.

I thought it would be ranked higher. How does it within the Asian region?

Japan is 6th in Asia.

Here are the populations of the countries in the Asian region as of 2023.

1. China – 1.485 billion
2. India – 1.38 billion
3. Indonesia – 276 million
4. Pakistan – 225 million
5. Bangladesh – 168 million
6. Japan – 123 million
7. Philippines – 114 million
8. Vietnam – 107 million
9. Iran – 82 million
10. Turkey – 80 million

China and India are in a different league! Is Japan’s population increasing year by year?

The population of Japan is declining due to a decreasing birthrate and an aging population.

However, from the perspective of the healthcare market, Japan is expected to see increasing demand due to its aging population.

The current elderly population (65 years and older) is approximately 36 million people, while the elderly population is predicted to be 40 million people in 10 years.

The Population by Region

Is Japan divided into several regions?

Yes, it is. Japan has 8 regions and 47 Prefectures. Firstly, the regions are as follows:

(Note: This data is based on the announcement from the Statistics Bureau of the Ministry of Internal Affairs and Communications.)

Kanto region is quite a big population.

Because Kanto region includes Tokyo. And Tokyo’s neighboring prefectures also have very large populations.

The location of each prefecture is shown below.

There’s a big difference in population between prefectures.

In the market view, is the number of hospitals proportional to the population?

Yes, it is. I will tell you more about the number of hospitals in my next article.
