THE STORY
The story behind the walls
Ujiteru developed Hachioji in the late sixteenth century as a replacement for Takiyama. The precise construction and relocation dates remain debated, and parts may have been unfinished. Maeda and Uesugi forces captured it during Hideyoshi’s Hojo campaign in 1590. Conservation of the palace-area walls and old approach in 1990 made excavation results more accessible.
LAYOUT & ARCHITECTURE
Read the landscape and the buildings.
The complex divides broadly into a lower settlement, residential area and upper stronghold. Masonry and enclosed entrances protect the palace, while ridges and slopes defend the heights. Understanding these functional zones helps explain the extensive site.
A CLOSER LOOK
Details worth a closer look.
Palace compound
This area is interpreted as Ujiteru’s residential compound. Hall and garden remains show that the mountain castle also hosted government and formal reception.
Paving and defended entrance
Conservation incorporates excavated masonry and paving. Turns and steps at the entrance reveal a carefully controlled approach.
Upper stronghold
The upper enclosures use the mountain itself for defence. Their walking conditions differ from the lower palace area, so each can be considered separately.
