The transition of Hamamatsu Castle 2

Hamamatsu Castle repeatedly underwent expansions and alterations during the time when Ieyasu resided in it.

3. Shokuho style fortifications by Yoshiharu Horio (1590 – 1600)

In 1590 (the 19th year of Tenshu) after the third siege of Odawara, Ieyasu was forced to relocate to the Kanto region by Hideyoshi Toyotomi and Yoshiharu Horio, the Toyotomi clan’s chief vassal, was made lord of the castle.

Yoshiharu as a display of the Toyotomi clan’s power built a citadel with high stone walls and a grand castle using Shokuho style fortifications(※), the latest technology at the time.

The stone walls in current day Hamamatsu Castle are thought to have been built during Yoshiharu’s time as castle lord.

(※)Typical citadels of the era had “high stone walls, tile roofing and foundation cornerstones”.

They are characteristic fortifications use by Nobunaga Oda, Hideyoshi Toyotomi and others.

4.Pre-modern era Hamamatsu Castle governed by Fudai Daimyo (hereditary warlords from clans who supported the Tokugawa clan). (From the early 17th century onwards)

In the year 1600 (the 5th year of the Keichou era) Hamamatsu Castle became the castle governed by Fudai Daimyo (hereditary warlords who served the Tokugawa clan) when Ieyasu triumphed against the western army in the battle of Sekigahara.

The era of the warring states ended and Hamamatsu Castle became an administrative institution for the sake of appearances.

The grandeur of the castle was lost in the early 17th century but the expansion of the third bailey and the establishing of the Ote-mon (main gate) etc. was conducted together with the maintenance of the castle town.
