Hikone Castle is one of only twelve Japanese castles to retain its original wooden keep, designated as a National Treasure. Built over twenty years, the construction was completed in 1622 using materials salvaged from the dismantling of Nagahama, Sawayama, and Otsu castles. Its architecture incorporates diverse defensive designs, including 'musya-gaeshi' curved stone walls and 'ishi-otoshi' chutes for dropping projectiles on attackers. The structure stands atop Mount Konki, overlooking Lake Biwa. The site preserves original gates, turrets, and the Genkyu-en Garden, a daimyo garden designed with views of the castle keep. The museum on-site, the Hikone Castle Museum, replicates the former residence of the Ii daimyo family. The castle is famously associated with the Ii clan, who served as high-ranking officials in the Tokugawa Shogunate.
