Japan's national rate fell to 1.14 in 2025, its 10th straight annual decline.
Births totaled 671,236, the fewest since records began in 1899, and Tokyo's rate dropped below 1.0, according to Kyodo News.
Nagi's rate hit 2.95 in 2019, an Okayama prefectural survey found, earning it the nickname "miracle town." It has eased since but stayed well ahead of the national figure, at 2.21 in 2020, 2.68 in 2021 and an estimated 2.21 in 2022, according to town data.
The town logged 172 official study visits in 2023, the most of any local government in Japan, in a survey by Nikkei Business Publications.
Then-Prime Minister Fumio Kishida toured it that year to study its methods, NHK reported.
