Oda Nobunaga (Japanese military architecture)

Oda Nobunaga was a powerful Japanese daimyo (feudal lord) known for revolutionizing military architecture during the late 16th century. He implemented innovative castle designs that prioritized defensibility, mobility, and flexibility, often integrating advanced fortification techniques such as concentric walls, strategic water moats, and strategic placement to deter enemies. His approach emphasized both strong fortifications and easier troop movement, enabling rapid response and offense. Nobunaga's architectural innovations contributed significantly to the unification efforts of Japan, setting new standards for castle construction and military strategy in the Sengoku period, and influencing subsequent castle design.
