Vanguard at Sekigahara — Ikeda Terumasa's Military Achievements at the Decisive Battle
Ikeda Terumasa, son-in-law of Tokugawa Ieyasu, participated in the Eastern forces at Sekigahara (1600) and played a key role, fighting fiercely against Ukita Hideie's forces. His military achievements earned him Harima-Himeji at 520,000 koku after the battle—a domain so vast he was called 'the Shogun of the West.' Terumasa undertook a major reconstruction of Himeji Castle (1601-09), creating the basic structure of the White Heron Castle as it stands today. Himeji Castle is a UNESCO World Heritage Site, and Terumasa's architectural achievement continues to captivate visitors 400 years later.
