Japan's Azuchi-Momoyama period saw a revolution in castle architecture. Towering tenshu, stone foundations, and intricate defense systems transformed castles into symbols of power and administrative centers, reflecting the era's political shifts.
These castles weren't just fortresses. They incorporated residential spaces, showcased wealth through elaborate decor, and sparked urban growth. The fusion of military and aristocratic elements in their design left a lasting impact on Japanese architecture and urban planning.
