Large two-way flows behind the net gains
The Statistics Bureau's 2025 resident-register migration report records 451,843 arrivals in Tokyo from other prefectures and 386,624 departures: a net inflow of 65,219. Fukuoka had 102,453 arrivals and 97,317 departures, leaving a net inflow of 5,136. These domestic inter-prefecture counts include foreign residents.
Even where Fukuoka gained 5,136 people on balance, roughly 100,000 moved in and roughly 100,000 moved out. The net number alone conceals how much movement took place.
Fukuoka receives from Kyushu and Yamaguchi, and sends toward Greater Tokyo
Drawing on several years of data, Fukuoka Prefecture's population vision describes net inflows from Kyushu and Yamaguchi and net outflows toward Greater Tokyo. Here, Greater Tokyo means Tokyo, Kanagawa, Saitama and Chiba.
Fukuoka can receive people from nearby regions while also sending people toward the capital region. This geographic pattern comes from a different analysis than the 2025 prefectural totals above.
People in their early twenties arrive from across Japan
In Greater Tokyo in 2025, Japanese movers aged 20–24 had the largest net inflow of any age group, at 80,443. That is the total for four prefectures, not Tokyo alone. The age range overlaps study and early employment, but a change-of-address record cannot tell us why each person moved.
For this age group, the Statistics Bureau reports a net inflow to Greater Tokyo from every prefecture outside the region. Young adults were arriving from across Japan, not just from Fukuoka.
