To understand “Japan as a country,” it is important to consider its historical background and the current state of its society and economy.

Japan’s land area is approximately 378,000 km², with about 70% being mountainous areas such as forests, resulting in a limited habitable area. The population is approximately 122.64 million (as of March 2026) and is declining, with a particularly pronounced concentration in the Tokyo metropolitan area. The aging population and declining birthrate are progressing, and a future decrease in the total population is predicted.

Overview of Japan’s Land Area and Population (as of 2026)
Land Area: Approximately 377,900 km² (consisting of Honshu, Hokkaido, Kyushu, Shikoku, Okinawa, and over 6,800 islands)
Total Population: Approximately 122,643,209 (Worldometer data as of March 15, 2026)
Population Distribution: Approximately 90% of the population lives in urban areas, with a concentration of population in the Tokyo metropolitan area (Tokyo, Kanagawa, Saitama, Chiba)
Land Characteristics: Approximately two-thirds of the land is covered in forests, and there is little flat land. Population Trends and Challenges
Population Decline and Aging Population:
The population has been declining since peaking in 2009, and the aging rate is extremely high.
It is predicted that the total population will decrease to 87 million by 2070.
Concentration in Tokyo:
More than 36% of the total population is concentrated in Tokyo, Kanagawa, Osaka, Aichi, and Saitama prefectures.
Aging Population:
The proportion of the total population aged 65 and over continues to rise.

Small Habitable Land Area
Mountains make up a large portion of the country, with mountains accounting for more than 70% of the land area. As a result, the proportion of flat land where people can actually live (habitable land area) is only about 27.3% of the total land area. Therefore, the population is densely concentrated in limited areas.
