Japan is offering to pay families to move out of its overcrowded capital, in an effort to revitalize countryside towns and boost the falling birth rate.Starting in April, families in the Tokyo metropolitan area, including those headed by single parents, will be eligible to receive 1 million yen ($7,700) per child if they move to less-populated areas across the country, according to a spokesperson from the central government.Super-aged nationThis problem, the migration of young people from the countryside to crowded cities, is a key factor in Japan’s larger demographic crisis, according to experts.Experts point to several factors: the high cost of living, limited space and lack of childcare support in cities make it difficult to raise children, meaning fewer couples are having kids.“Tokyo has a very high concentration of people, and the government wants to increase the flow of people to the regional areas to revitalize areas with declining populations,” he added."
