The area of Saga was settled in the
Jōmon and
Yayoi periods and was part of ancient
Hizen Province. The ruins of the
Hizen Provincial Capital have been located in the former
Yamato neighborhood of the city. In the
Sengoku period, the area was controlled by the
Ryūzōji clan, but in 1608 the clan was replaced by their senior retainer,
Nabeshima Naoshige, who became
daimyō of
Saga Domain under the
Tokugawa shogunate. Saga, formerly a small town centered on water transportation and agriculture, developed into the
castle town of the domain after the construction of
Saga Castle, and commerce and industry flourished. The domain due to its proximity to
Nagasaki, it actively introduced Western science and technology, and in the
Bakumatsu period was one of the main centers involved in the
Meiji restoration.
