Shinpu Castle, Japanese castle in Nirasaki, Japan
Shinpu sits on Mount Nishimori at 524 meters (1719 feet) elevation and comprises earthen walls, dry moats, and several defended courtyards spread across 257,721 square meters (62 acres). The layout shows a calculated arrangement of different levels that use the natural slope of the mountain and connect through steep embankments.
Takeda Katsuyori built the site in 1581 as his new seat and left behind the old stronghold of his family. The siege by Oda and Tokugawa forces lasted only 68 days before it fell and Katsuyori withdrew.
The name means "New Capital" and reflects Katsuyori's ambition to refound his realm. The shrine within the grounds remains a place of worship today, where visitors light incense and offer prayers.
Access is through JR Shinpu Station on the Chuo Line, from which a 15-minute walk leads to the main courtyard. The paths are partly steep and uneven, so sturdy footwear and some stamina are helpful.
The northwest entrance shows a rare masugata gate, formed by two earthen walls in succession, creating a trap for attackers. This detail is unusual for a mountain castle and shows the architect's experience in warfare of that era.
