Kaminogō Castle

Kaminogō Castle is a medieval fortress in Gamagori situated on a hilltop overlooking Mikawawan Bay in Aichi Prefecture. The ruins span a large area and display remains of defensive walls, water channels, and fortification structures from that period.

The castle was captured in 1562 by Tokugawa Ieyasu during the Sengoku period through a successful assault against the Imagawa clan. This victory marked a significant step in Ieyasu's rise to power amid Japan's competing warlords.

The site displays traditional Japanese castle design with defensive clay walls and strategically positioned water channels. Visitors can still observe the traces of these military structures while walking through the grounds.

The grounds today are partly surrounded by residential areas and mandarin orchards, with marked paths guiding visitors through the ruins. It is best visited on a clear day to enjoy the views across the bay and surrounding landscape.

The legendary ninja commander Hattori Hanzo carried out a critical operation during the 1562 siege to rescue Tokugawa Ieyasu's daughters. This event made the site a memorable chapter in the dramatic power struggles of the Sengoku period.
