Komakiyama Castle
概要
Komakiyama Castle was built by Oda Nobunaga in 1563 and represents a revolutionary turning point in Japanese castle architecture. Nobunaga transformed the entire 86-meter hill into a planned fortress city, using stone walls — unprecedented for mountain castles of the era — and integrating a castle tower, samurai quarters, roads, and a castle town below. Though used for only four years before Nobunaga moved to Gifu Castle, its innovations laid the conceptual groundwork for Azuchi, Osaka, and Edo castles. In 1584 the castle served as Tokugawa Ieyasu's headquarters in the Battle of Komaki and Nagakute against Toyotomi Hideyoshi.
與刀劍的關聯
Oda Nobunaga was one of history's most passionate sword collectors, conducting his famous 'meibutsu-gari' (treasure hunts) to forcibly acquire legendary blades from daimyō, temples, and merchants. At the time Komakiyama Castle was in use, Nobunaga was amassing his collection, including the beloved tantō Yagen Tōshirō (attributed to Awataguchi Yoshimitsu), which legend says refused to cut him. Many of his treasured blades perished in the 1582 Honnōji fire, but survivors reached the Tokugawa family and other daimyō. Nobunaga pioneered 'sword diplomacy' — gifting famous blades as political currency — a practice inherited by Hideyoshi and Ieyasu. The nearby Tokugawa Art Museum in Nagoya holds Nobunaga-associated swords.
