Net migration Japan in 2023, by prefecture

Tokyo Prefecture continued to be a magnet for domestic migration in Japan, attracting nearly 58,500 new residents from other prefectures in 2023. By contrast, Hiroshima Prefecture showed the highest population loss due to outbound migration within the country, with a net loss of approximately 7,400 migrants.

Attractiveness of Tokyo

The population density in the prefecture has grown over the past two decades, surpassing 6,400 inhabitants per square kilometer in 2020. The appealing nature of Tokyo is also reflected in the age demographics of the metropolis, with most residents falling within the working-age group of 15 to 64 years. Numerous prestigious universities and large corporations make the area a popular destination for young people with aspirations.

Depopulation of rural areas

The migration patterns across Japan's prefectures indicate significant regional disparities. While Tokyo leads in population size with 14 million inhabitants in 2023, prefectures like Tottori struggle to retain residents, counting only about 540,000 people. This imbalance has prompted concerns about the sustainability of rural communities and has led to various initiatives aimed at revitalizing less populous areas. The Japanese government faces the complex task of addressing these demographic shifts while also navigating challenges resulting from a nationwide aging population due to prolonged life expectancy and fertility decline.
