田辺城（舞鶴城）
Tanabe Castle (Maizuru Castle) is a historic castle in kinki dating from the Built in 1580 (Tensho 8), whose lord was Hosokawa Fujitaka (Yusai).
Overview
Tanabe Castle (also called Maizuru Castle) in Tango Province was built by Hosokawa Fujitaka (Yusai) in 1580. Yusai was an extraordinary figure who served three successive hegemons — Nobunaga, Hideyoshi, and Ieyasu — and was equally renowned as a master of waka poetry, court protocol, and swordsmanship. In 1600, the castle became the site of a legendary siege: Yusai, holding out against a Western Army force of thousands with only 500 men, was the sole living transmitter of the Kokin denju (the secret oral tradition of the Kokinshu anthology). Emperor Go-Yozei sent an imperial envoy to halt the siege and preserve this literary treasure — one of history's most remarkable intersections of martial conflict and high culture.
Connection to Swords
Hosokawa Yusai (Fujitaka) was renowned as a man of culture, versed in waka poetry and the Kodai Dentoju transmission, yet his accomplishments as a military commander were equally distinguished. Yusai possessed deep knowledge of martial strategy (heihō) and exceptional mastery of swordsmanship, having received instruction in sword arts from the Ashikaga shogun's swordsmanship masters. The Hosokawa family was known throughout generations as a celebrated sword-collecting house; in particular, Yusai's son Tadaoki (Sansai) stands as one of Japan's most celebrated sword collectors in history. Tadaoki laid the foundation for the Hosokawa family collection, exemplified by the Eisei Bunko, and his sword collection spanned a wide range—from Bizen and Soshu works to blades forged with southern-barbarian iron (nanban-tetsu). The swords Yusai himself possessed formed a valued part of "Hosokawa-mono" (Hosokawa-school pieces); the blade he carried during the Tanabe Castle siege was transmitted to posterity as the "siege sword." Both Oda Nobunaga and Toyotomi Hideyoshi, whom Yusai served, were celebrated sword collectors, and from both Yusai received named blades as gifts, thereby enriching his own collection. During the siege of Tanabe Castle—a pivotal historical event—the sword that Yusai and 500 samurai warriors grasped together became a symbolic embodiment uniting his role as protector of the Kodai Dentoju heritage and his identity as a martial warrior. The ideal of "the unity of civil and martial arts" (bun-bu no itchi) was the very essence of Hosokawa Yusai's life, and this ideal deeply resonates with the sword's own pursuit of "unity between sharpness and beauty of form." The Hosokawa family collection, inherited by Tadaoki's grandson Mitsuhisa as daimyo of Kumamoto domain, survives today as the Eisei Bunko in Tokyo, containing numerous swords designated as National Treasures and Important Cultural Properties. The Tanabe Castle Museum displays materials relating to Hosokawa Yusai and Tanabe Castle, transmitting the image of an ideal military commander who embodied both martial and cultural excellence.
