宇土城
Uto Castle is a historic castle in Kyūshū dating from the Founded in the 14th century; developed by Konishi Yukinaga in the 1590s, whose lord was Nawa clan / Konishi Yukinaga.
Overview
Uto Castle is a hira-yamajirō (plains-mountain castle) located in Uto, Kumamoto Prefecture, and ranks among Kyushu's finest early-modern castles. It was built by Konishi Yukinaga on a strategic peninsula site after he was granted the southern half of Higo Province by Toyotomi Hideyoshi in Tenshō 16 (1588). Yukinaga served as one of the principal commanders in the Korean campaigns (Bunroku-Keichō campaigns), and Uto Castle became the headquarters for his military and cultural activities.
Konishi Yukinaga was a Christian with the baptismal name Don Agostino, and Christian culture took firm root in the Uto castle town. Yukinaga promoted the construction of churches and schools, and Uto became one of the principal centers of Christian (Kirishitan) culture in Kyushu. Furthermore, Yukinaga actively engaged in Nanban trade with Portugal and Spain, and a cosmopolitan commercial city flourished where exotic goods were gathered.
At the Battle of Sekigahara in Keichō 5 (1600), Yukinaga sided with the Western Army (Ishida Mitsunari faction), and was executed after the victory of the Eastern Army (Tokugawa Ieyasu faction). Uto Castle was granted to Katō Kiyomasa, who maintained Uto Castle while devoting his attention to the development of Kumamoto Castle. During the Edo period it functioned as a branch castle of the Hosokawa domain, but today it has been preserved as a historical site park by Uto City.
The castle ruins preserve large stone-foundation structures estimated to have supported a watchtower-style keep with three tiers and five stories. The unfinished stone platform known as the "phantom three-story tower" testifies to the magnitude of Yukinaga's grand vision.
Connection to Swords
Uto Castle's sword heritage centers on Konishi Yukinaga's dual role as a Christian general and one of Hideyoshi's finest commanders. His troops carried fine swords into the Korean campaigns and returned with Korean metalwork and craftsmanship influences. The Kyushu sword tradition — particularly the Hizen-mono (Saga-area blades) that flourished in the Edo period — owes much to Sengoku-era military demand in the region, with Uto Castle town among the centers of that patronage. Yukinaga's successor, Katō Kiyomasa (one of the Seven Spears of Shizugatake), was a celebrated sword collector; the weapons seized at Uto were absorbed into his collection, now partly displayed at Kumamoto Prefectural Art Museum and Katō Shrine. The Uto-to-Kumamoto corridor represents a rich vein of Kyushu sword culture.
