As of 2005, the city has an estimated population of 67,428 and a density of 2,277.20 persons per km². The total area is 29.61 km².
The city was officially founded on April 1, 1982, although it has been important historically for around a thousand years.
Dazaifu was sometimes attacked by rebels. At other times the head of Dazaifu himself raised a rebellion.
With the invasions of the Mongols and the decline of imperial authority, Dazaifu became less politically significant. In the Muromachi period the political center of Kyūshū was moved to Hakata.
In medieval times, Dazaifu was the base of the Shoni clan, which was later expelled by the Ōuchi clan.
In the Edo period, Dazaifu was a part of Kuroda han till its abolishment in 1873.
The Kyushu National Museum opened on October 16, 2005. A striking wood and glass building in a hilly landscape, it hosts collections of Japanese artifacts, related to the history of Kyūshū. Komyozenji is a Zen temple famous for its beautiful stone garden. Komyozenji was built during the Kamakura period just next to Dazaifu Tenman-gu. All three are within walking distance of the Nishitetsu station.
Dazaifu's elementary, junior high and high school are administered by Dazaifu Board of Education.
