Karatsu, Saga
Due to its proximity to mainland Asia, Karatsu has long been known as a stopover to Korea and China.Under ritsuryō, the current city area was part of the Hizen Province. In 1591, on the coast of the northern part of the city (formerly the town of Chinzei), Nagoya Castle was constructed. The following year, it became the location from which the Imjin War was launched by Toyotomi Hideyoshi. In the middle of 1593, Terasawa Hirotaka created the Karatsu domain and began governing it. In 1602, replacing Nagoya Castle, Karatsu Castle was constructed in what is now the heart of Karatsu. The tower of Karatsu Castle was built in 1966 .
Nagoya Castle
After the deployment of a garrison of the Imperial Army in 1872, the whole Sannomaru enceinte of the castle was placed under their control in 1874. The warehouse was probably constructed in 1880 (Meiji 13) as an army ammunition depot. It was named after General Nogi Maresuke, who was posted to Nagoya during the early Meiji era (1868–1912). It is the only warehouse that has survived in the Ofukemaru.
