• Hokkaido: 66.4 ppl/km2
• Tōhoku: 130 ppl/km2
• Kantō: 1300 ppl/km2

Population Projections :

Japan population will decrease to 100 million people by 2049 from where it is now at 127 million and will continue to decrease to just above 50 million by 2100.

Japan’s population decline has several social and economic repercussions, such as one-third of the population being elderly by 2036 and a lack of working-age people to help keep the economy growing.

Answer 1

Japan has a total area of 377,930km Sq and  is politically divided into 8 regions and 47 prefectures. Japan is with a population density of 334.66/km2.All primary and secondary regions of high population density lie on the coastal region and one-third of the population resides in and around Tokyo on the central plain (Kanto Plain).

Currently Japan has a total population of 127 million. It is expected that the population of Japan will decrease to 100 million by 2049 and by 2100 the population of Japan will just 50 million.

The declining trend of Japan's population has greater social and economic repercussions.One third or about 33% of Japan's population will be dependent elderly by 2036.This indicates that there will be a decrease in the working age population in Japan. So, the contribution to the GDP by the working age population decreases. This negatively affects the economic growth.
