History

The area of Sanmu was part of ancient Kazusa Province. The city of Sanmu was established on March 27, 2006, from the merger of the towns of Sanbu, Matsuo and Narutō, and the village of Hasunuma (all from Sanbu District). The kanji for the city name are the same as for the former town of Sanbu, but is pronounced differently. Sanmu was damaged by a tsunami as a result of the 2011 Tōhoku earthquake and tsunami, with 43 buildings destroyed and 438 buildings partially destroyed, but with only one fatality.
