Kiyosu Castle
After Nobunaga's death, Toyotomi Hideyoshi assembled his retainers at Kiyosu Castle and proclaimed his regency over Nobunaga’s infant grandson, Oda Hidenobu. Kiyosu Castle itself came under the control of Nobunaga’s second son, Oda Nobukatsu, who began large scale renovations in 1586, which included a double ring of moats, as well as a large and a small donjon It was remodeled by expanding the castle grounds to roughly 1.6 km east to west and 2.8 km north to south. However, Nobukatsu fell afoul of Toyotomi Hideyoshi when he refused orders to change his domains, and was replaced at Kiyosu by Fukushima Masanori in 1595. After the Battle of Sekigahara in 1600, Fukushima Masanori was relocated to Hiroshima Castle, and Kiyosu was reassigned to Tokugawa Ieyasu’s 4th son, Matsudaira Tadayoshi. However, he was in poor health from wounds suffered at Sekigahara, and died in 1607. The castle then passed to Tokugawa Yoshinao. In 1609, by order of Tokugawa Ieyasu, Yoshinao was ordered to relocate the seat of his government to Nagoya Castle. The move occurred from 1609-1613, during which time most of the buildings of Kiyosu Castle were dismantled and relocated to Nagoya. Parts of Nagoya Castle were reconstructed with the use of building materials taken from Kiyosu Castle. The northwest turret of Nagoya Castle's Ofukemaru fortress was called the "Kiyosu Yagura," as it was constructed using parts taken from the Kiyosu Castle donjon. The original "kinshachi" (金鯱) from Kiyosu Castle are now preserved in the Buddhist temple of Sōfuku-ji in Gifu City in neighboring Gifu Prefecture, and a former gate of the castle is preserved at the temple of Ryōfuku-ji in Owari-Asahi and some of the decorated sliding doors from the castle are at the temple of Soken-ji in Naka-ku, Nagoya.
