Japan's population has been steadily declining since its peak in 2008, with the World Bank estimating it at 126 million people in 2020. This decrease can be attributed to a combination of factors such as a declining birth rate, an aging population, and an increased death rate due to the country’s aging population. Solutions to increase population growth include implementing policies encouraging couples towards parenthood such as tax breaks or subsidies, improving access and availability of affordable childcare options, and potentially immigration. However, any attempt to increase immigration would also need to be supported by appropriate infrastructure and services in order for immigrants to settle comfortably into society without facing prejudice or other barriers.
