Kiyosu Castle, Aichi Prefecture – Samurai World

Kiyosu Castle, Aichi Prefecture

Kiyosu Castle

Kiyosu Castle was first built around 1405 by Shiba Yoshishige, the Governor of Owari, as a major strategic defense, and later the seat of power for the Owari (now Aichi Prefecture) region. One of the two Oda clans, administrators of Owari, the southern Owari based Oda, took control of southern Owari and Kiyosu Castle from 1476. (The other branch of the Oda clan was based in Iwakura Castle and controlled the northern Owari regions)

Kiyosu Castle was the starting point for many of the historically significant samurai battles that took place in the violent Sengoku or Warring States Period (1450-1615). The major battles of Okehazama, (1560) Anegawa, (1570),  Nagashino(1575) and Sekigahara (1600) were initially launched from Kiyosu.

In 1555, after his father’s death, Oda Nobunaga enlisted the help of his uncle, Oda Nobumitsu, and together they attacked and killed Oda Nobutomo, the clan leader at Kiyosu Castle. Nobunaga then moved from Nagoya Castle to Kiyosu.

Two years later, Nobunaga’s younger brother Nobuyuki is believed to have conspired against him. Nobunaga discovered his brothers’ plot to oust him, and faked an illness to draw his brother close. When Nobuyuki came to pay his respects to his “ill” brother, Nobunaga is said to have assassinated him within Kiyosu Castle, eliminating any opposition and ensuring clan stability.

Kiyosu would remain his base for many years. During that time, Kiyosu grew to be one of the more vibrant cities, spurred on by Nobunaga’s economic reforms and heightened security. The castle once extended 1.6 kilometers east-west, and 2.8 kilometers north- south, having an outer, central and inner moat system.

Kiyosu Kaigi, The Kiyosu Conference

On July 16, 1582, just weeks after Oda Nobunaga was killed at the Honno-ji Temple in Kyoto, a very important meeting regarding the Oda clan’s succession was staged at Kiyosu Castle. This important meeting is known as the Kiyosu Kaigi, or the Kiyosu Conference.

The Oda’s top retainers, including Shibata Katsuie, Toyotomi Hideyoshi, Niwa Nagahide and Ikeda Tsuneoki gathered at Kiyosu Castle to decide on Nobunaga’s successor. The conference was to become Japan’s first group-made political decision. As Nobunaga’s designated heir, Nobutada, had died at Nijo Castle immediately following his fathers death, the succession situation was further complicated. The leadership would be contested by Toyotomi Hideyoshi who suggested Oda Samboshi, the two year-old infant grandson of Nobunaga, and son of Nobutada, and Shibata Katsuie who championed Nobunaga’s third son, Nobutaka. It would appear to many that in raising Nobunaga’s grandchild to the leadership position, his “supporter” Toyotomi Hideyoshi could usurp power for himself in the name of Samboshi.

The conference ended without resolution. The next few months saw rising tension between Hideyoshi and Shibata Katsuie, culminating in the battle of Shizugatake. Finally, pursued by the Toyotomi, a defeated Shibata Katsuie retreated his castle at Kitanosho in Fukui Prefecture, set it alight, and killed himself. Hideyoshi successfully usurped the Oda’s power, and went on to conquer and rule Japan in his own right.

Kiyosu Castle would then see a variety of masters until the Battle of Sekigahara in 1600.

The actual site of Kiyosu Castle is on the opposite banks of the river from the reconstructed keep

Parts of Kiyosu Castle’s keep were recycled to build Nagoya Castle’s Kiyosu Yagura watchtower.

Kiyosu Castle Today

Kiyosu Castle was reconstructed in concrete in 1989 across the small river from where the actual castle stood. The site of the actual keep now has the “Kiyosu Furusato no Yakata” a small rest area and souvenir stall on it.

Shockingly, the JR train lines and Bullet Train lines run directly through the old castle site! The southern half of Kiyosu Castle is now a park featuring a rather handsome statue of Oda Nobunaga in full armor, with another of his wife, Princess No-Hime, looking on.

The current reconstructed Kiyosu Castle is now a symbol of Kiyosu City and a well-planned museum featuring some fascinating displays and artifacts regarding the castles’ history, and its part in the many battles of the Period of Warring States.
