Map: GSI Japan Shizugatake was not a single clash on one summit. In 1583, forces aligned with Hashiba Hideyoshi and Shibata Katsuie constructed a chain of field fortifications for more than ten kilometres around Lake Yogo and the northern Ōmi corridor. Nagahama City's heritage study counts roughly twenty major positions and emphasizes their unusually coherent survival as a short-lived late-Sengoku fortress system. The fighting that broke the stalemate included the assault on Nakagawa Kiyohide at Ōiwayama, Hideyoshi's rapid return from the Gifu front, the collapse of forward Shibata positions, and Maeda Toshiie's withdrawal. Present evidence ranges from mountain earthworks and a nationally designated headquarters ruin to graves, later battle markers, a modern summit statue, and a landscape divided by roads, railways, forest, and agriculture.
