Chugoku Castles

中国

Chugoku, the westernmost region of Honshu, was a contested corridor between the powerful clans of central Japan and the domains of Kyushu, giving rise to some of Japan's most strategically sited fortresses. The Mori clan ruled much of this region at its peak, building and contesting castles that overlooked the Seto Inland Sea and its vital shipping lanes. Survivors like Matsue Castle — one of only twelve original keeps in Japan — stand as quiet reminders of centuries of maritime and mountain warfare.
