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.

Tsuyama Castle
津山城 · Tsuyama-jo

Stone walls without a tower — Tsuyama's vast terraced ishigaki are a lesson in how much castle architecture is really about the ground, not the building on top of it.
Hagi Castle
萩城 · Hagi-jo

The only castle in Japan with a bullet train running through it — look down from the platform and you are looking at 16th-century stone walls.
Gassan-Toda Castle
月山富田城 · Gassan-Toda-jo
📍 Shimane — Chugoku
Japan's most impregnable mountain fortress — the Amago clan's stronghold that Mori Motonari besieged twice (failing the first time entirely), and the birthplace of Yamanaka Shikanosuke's legendary loyalty.
Bitchu-Takamatsu Castle
備中高松城 · Bitchu-Takamatsu-jo

Yoshida-Koriyama Castle
吉田郡山城 · Yoshida-Koriyama-jo
