The northern coast area of
Hizen Province (modern-day Saga and
Nagasaki Prefecture was held by
Matsura clan, who engaged in trade and
piracy around
East China Sea and
Tsushima Strait from the end of the
Heian period. The clan was active in the defense of Japan during the
Mongol invasions of Japan of 1274 and 1281. However, by the
Muromachi period, the clan had become subordinate to their more powerful neighbors, such as the Hata clan. After
Toyotomi Hideyoshi's
Kyūshū campaign of 1586-1587, his general
Terazawa Hirotaka was awarded the area. After Hideyoshi consolidated his control over Japan with the defeat of the
Odawara Hōjō in 1590, he turned his attention to invasion of the
Korean Peninsula as a stepping stone to conquest of
Ming China. Needing a field headquarters in northern Kyushu as a command center, Hideyoshi found the place name "Nagoya", the same as his hometown of
Nagoya (albeit with different
kanji), to be a pleasing coincidence, and was also pleased by the auspicious name of the mountain on which the castle stood, Mount Katsuō, and decided to build a castle there. The planning of the castle was made by
Kuroda Yoshitaka, and actual construction were performed by local lords of Kyushu under the command of
Kato Kiyomasa and
Fukushima Masanori. The construction was started from the autumn of 1591, and competed in the spring of 1592. Feudal lords from all over the country were ordered to amass at the site and to contribute to a portion of its construction. Its scale was second only to
Osaka Castle among castles of the time. Hizen Nagoya castle spread along a 50 meter hillside, which spread to southeast and southwest from the center point. The
central enclosure was a square shaped area of 100 meter length at the highest point of the hill. At the north edge of the central area, where is the crossing point of two ridges, there was a seven-story
tenshu. The
tenshu was surrounded by concentric
enclosures with
masugata-style compound gates, and the complex included a palace for Hideyoshi and his concubine
Yodo-dono. The Total size of Hizen Nagoya Castle was over 1000 meters long and 500 meters wide, and whole part of the castle were protected by stone walls. However, as the castle was not actually designed for use in combat, so its stone walls were relatively low and the number of
yagura turrets was few in relation to the castle's size. In June 1592, Dominican friar
Juan Cobo arrived in Japan and met with Hideyoshi at Nagoya Castle, which was still under construction. It is said that during the brief time that Hideyoshi stayed at Nagoya Castle, he memorized the
shite (lead role) parts for ten
Noh plays and performed them, forcing various
daimyō to accompany him onstage as the
waki (accompanying role), and even performed before the
Emperor. Hideyoshi gathered all of his lords to this area, irrespective to actual participation to military action, many of whom constructed permanent bases guarded by stone walls surrounding the main castle complex. Within a three-kilometer radius were the camps of about 118 vassals. A town grew up around the military establishments, with a population of over 100,000 people at its height. According to the
Matsuura Kojiki, over 205,570 soldiers, mostly from western Japan, crossed over to Korea in the first months of the
Imjin War in 1592, and a further 102,415 soldiers, mostly from eastern Japan, were stationed around Hizen-Nagoya. Water sources were insufficient to support such a large force, and fighting caused by water shortages was constant. Hideyoshi commanded operations from this castle, but on his death in 1598,
Tokugawa Ieyasu ordered the withdrawal of all Japanese forces from Korea. With the establishment of the
Tokugawa Shogunate, the castle was ordered to be demolished. It was too large to demolish, but foundations of
tenshu was thoroughly destroyed as a symbol of the castle. Many stones and some structures were relocated for the construction of
Karatsu Castle, ten kilometers to the south.
Date Masamune is said to have dismantled the castle main gate (Otemon) and moved it to his stronghold of
Aoba Castle in
Sendai. Further, after the
Shimabara Rebellion in 1637, the shogunate ordered more of the castle's remaining walls to be destroyed, to prevent the possibility of any use in any future rebellion. Plans were floated in 1956 for building a reconstruction of Nagoya Castle as a tourist attraction; however, the plan was rejected by the national government in 1962, citing a lack of solid historical evidence of the castle's appearance, as well as negative political issues regarding the site as having been a base from which Japan invaded Korea. ==See also==
