A Rich Historical Legacy
The history of Usuki is deeply intertwined with the ancient Bungo Province. During the Edo period, the area was primarily governed by the Usuki Domain under the rule of the Inaba clan. A pivotal moment in international relations occurred in April 1600, when the ship "De Liefde" ran aground on the coast of Bungo. This event brought William Adams and other crew members to the region, sparking a long-standing Dutch-Japanese trading partnership.
The modern administrative structure of Usuki began to take shape in 1889. Over the following decades, the city expanded through several annexations of neighboring villages, eventually reaching its current form after the merger with the town of Notsu in 2005.
