郡上八幡城
Gujo Hachiman Castle is a historic castle in Chūbu dating from the Founded in 1559 (Eiroku 2) by Endo Morikazu, whose lord was Endo Yoshitaka / Aoyama Clan / Inoue Clan / Kanamori Clan / Aoyama Clan (restored).
Overview
Gujo Hachiman Castle is a mountain castle located along the Nagara River in Gujo City, Gifu Prefecture, and is renowned as a castle of breathtaking beauty, dubbed 'Castle in the Sky' and 'Premier Castle of Tokai.' Founded in 1559 (Eiroku 2) by Endo Morikazu on Hachiman Mountain (elevation 354 meters), the castle has weathered numerous historical upheavals including the Battle of Sekigahara, the One Castle per Domain Edict, and successive changes of daimyo, yet its wooden tenshu, reconstructed in 1933 (Showa 8), continues to stand majestically atop the mountain.
What distinguishes Gujo Hachiman Castle is that its present tenshu was established early on as a 'Showa-era wooden reconstructed tenshu.' The 1933 reconstruction was a wooden structure built with reference to historical blueprints and architectural drawings, and is now recognized as an 'extant wooden tenshu' of significant cultural value. From the tenshu, visitors enjoy sweeping views of the Gujo Basin, the Nagara River, and surrounding mountains; the early morning landscape shrouded in mist is particularly beloved by photographers as 'Gujo Hachiman Castle in the Clouds.'
During the reign of daimyo Kanamori Yorikane, Gujo became the stage for a peasant uprising known as the 'Gujo Ikki' (also called the Horeki Disturbance, 1754–1758). Farmers resisted the increased tax levies imposed by Aoyama Yukimichi, escalating to a direct petition to the shogunate's senior councillor Tanuma Okitsugu. The uprising was resolved by the shogunate's decision to transfer the domain's daimyo—a rare instance in Japanese history where the shogunate acknowledged peasant grievances.
Gujo Hachiman is also known as the 'City of Water,' and the pristine Yoshida River flowing through the castle town is famous for its summer diving. The 'Gujo Odori' is one of Japan's three great Obon dances, and its all-night dancing held every summer is a point of regional pride. This rich culture of water and dance is inseparable from the spirit of the castle town that Hachiman Castle has long protected.
Connection to Swords
The relationship between Gujo Hachiman Castle and swords is rooted in its geographical location adjacent to Mino and Hida, major centers of sword production, and in the samurai culture of the castle lords—the Endo clan and their successors. Mino Province, where Gujo Hachiman Castle stands, was a major center of sword production known as 'Mino-mono' (Mino blades), and the swordsmiths of Seki City, represented by the Seki smithing tradition, hold a unique place in Japanese sword history. Gujo is adjacent to Seki City, and the samurai of Gujo enjoyed ready access to swords forged by Mino smiths. The Endo clan was a samurai house that rose under the influence of Saito Dosan and the Saito daimyo who ruled Mino, and they were deeply immersed in Mino's sword culture. Seki swordsmiths supplied swords to numerous warlords during the Sengoku period, and it is believed that the lords of Gujo Castle also valued practical, combat-ready Seki blades. The characteristics of Mino blades lie in their hamon patterns—gunome-midare, togari-ba, and sanbon-sugi formations—and they are highly regarded as swords combining practical utility with aesthetic refinement. In the Edo period, the daimyo of Gujo Domain—the Aoyama and Inoue clans—maintained close ties to the Tokugawa house and collected swords from smiths favored by the shogunate. During the Gujo Ikki, weapon management became a contentious issue within the domain, and proper sword stewardship became a critical concern in domain administration. In modern times, Gujo City retains sword-related craft shops and traditions of blade production, reflecting continuity with the castle town's artisan heritage. Armor and swords displayed in the tenshu of Gujo Hachiman Castle convey aspects of the daimyo's samurai culture to the present day, and serve as invaluable material evidence for understanding the relationship between Mino sword culture and the samurai culture of Gujo.
