Construction Begins on Nagoya Castle

Tokugawa Ieyasu ordered construction to begin on Nagoya Castle, a strategic fortress meant to guard the approach to Kyoto and secure the new Tokugawa shogunate.

Built using forced labor from rival feudal lords as a display of loyalty and submission, Nagoya Castle became one of Japan's largest and most important fortifications, its golden shachihoko roof ornaments becoming an enduring symbol of the city. The castle stood for over three centuries before being destroyed in Allied bombing during World War II and later reconstructed.

After winning decisive control of Japan at the Battle of Sekigahara, Tokugawa Ieyasu set about consolidating his new shogunate by fortifying key strategic points, and Nagoya, positioned along the route between Edo (Tokyo) and Kyoto, was among the most vital. Construction is traditionally dated to 1610, when Ieyasu compelled numerous feudal lords allied to or wary of him to contribute labor and resources — a shrewd move that drained rivals' coffers while displaying their submission.

The castle's most famous features became a pair of golden shachihoko, mythical dolphin-like creatures perched atop the main keep's roof, gleaming with real gold leaf and symbolizing the wealth and power of the Tokugawa clan. The castle town that grew around it developed into modern Nagoya, now one of Japan's largest cities.

The original structure survived until 1945, when American bombing raids reduced it to ashes along with much of the city. Postwar reconstruction, completed in 1959 using concrete rather than wood, restored its silhouette, and the golden shachihoko remain a beloved civic symbol, even surviving a wartime theft attempt when thieves tried to shave gold flakes off the roof ornaments during the chaos of the firebombing.
