Historic Sites of Saga Prefecture
In ancient times, the area composed by Nagasaki Prefecture and Saga Prefecture was called Hizen Province. The current name dates from the Meiji Restoration. Rice farming culture has prospered here since ancient times, and vestiges can be seen at the ruins of Nabatake in Karatsu and the Yoshinogari site in Yoshinogari.
From the Kamakura period to the Muromachi period, it is thought that over 100 feudal clans existed. Also exerting great influence during this time was a samurai clan operating along the Genkai Sea called the Matsuratō. Upon entering the Sengoku period, the Ryūzōji clan expanded their control to include all of Hizen and Chikugo Provinces, and part of Higo and Chikuzen Provinces. After the death of daimyō Ryūzōji Takanobu, Nabeshima Naoshige took control of the political situation, and by 1607 all of the Ryūzōji clan's domain was under the control of the Nabeshima clan.
In the Edo period this area was called the Saga Domain (佐賀藩 Saga-han), and it included three sub-domains: the Hasunoike, Ogi and Kashima Domains. Also within the current borders of Saga Prefecture during this time were the Karatsu Domain (唐津藩 Karatsu-han) and two territories of the Tsushima-Fuchū Domain (対馬府中藩 Tsushimafuchū-han). Saga Domain and its sub-domains continued to be ruled by the Nabeshima clan, its various illegitimate family lineages and members of the former Ryūzōji clan, and politically the area was relatively stable.
