Shikoku Castles
四国Shikoku, the smallest of Japan's four main islands, punches well above its size in castle heritage, preserving three of Japan's twelve original wooden tower keeps in a single compact region. The island's rugged interior mountains and narrow coastal plains shaped a style of castle architecture that emphasized natural terrain over artificial fortifications. Visiting Shikoku's castles today feels like stepping into a quieter, less-touristed Japan where history is worn lightly.
Prefectures
Tokushima, Kagawa, Ehime, Kochi
Matsuyama Castle
松山城 · Matsuyama-jo
📍 Ehime — Shikoku
Shikoku's best castle experience — a genuine original tower on a commanding hilltop, reached by ropeway, with great facilities and the literary ghosts of Shiki and Soseki.
Kochi Castle
高知城 · Kochi-jo
📍 Kochi — Shikoku
Japan's most complete castle experience — the only place where both an original tower and original lord's palace survive side by side.
Marugame Castle
丸亀城 · Marugame-jo
📍 Kagawa — Shikoku
Tiny tower, titanic walls — Marugame Castle's stacked stone masonry is some of Japan's finest, at a price that's almost embarrassingly cheap.
Takamatsu Castle
高松城 · Takamatsu-jo
📍 Kagawa — Shikoku
Japan's castle that floated on the sea — three original turrets, seawater moats, and a missing main tower that may yet return.
Imabari Castle
今治城 · Imabari-jo
📍 Ehime — Shikoku
The master castle builder's seawater masterpiece — Imabari's tidal moats are a brilliant piece of military engineering that doubles as the start of Japan's best cycling route.
Ozu Castle
大洲城 · Ozu-jo
📍 Ehime — Shikoku
The castle that was rebuilt without a single nail — Ozu's 2004 wooden reconstruction is the closest thing in modern Japan to actually entering a 17th-century castle tower.
Uwajima Castle
宇和島城 · Uwajima-jo
📍 Ehime — Shikoku
Remote, unhurried, and genuinely old — Uwajima's original tower is a quiet pilgrimage for those who seek authentic history off the tourist trail.
Tokushima Castle
徳島城 · Tokushima-jo
📍 Tokushima — Shikoku
Awa Odori's ancestral castle — green schist walls and a Toyotomi-era garden in a city that dances better than it fortifies.
Yuzuki Castle
湯築城 · Yuzuki-jo
📍 Ehime — Shikoku
The castle that sits invisible beside Japan's most famous hot spring — Yuzuki's 250-year history is walked past by thousands of Dogo Onsen visitors who never know it exists.
Oko Castle
岡豊城 · Oko-jo
📍 Kochi — Shikoku
Where Chosokabe Motochika began his conquest of all Shikoku — one of the Sengoku period's greatest stories starts at this modest mountain castle above Kochi.
Hiketa Castle
引田城 · Hiketa-jo
📍 Kagawa — Shikoku
Coastal promontory castle above the Seto Inland Sea — natural rock integrated into stone walls at Shikoku's eastern maritime gateway.
Kawanoe Castle
河後森城 · Kawanoe-jo
📍 Ehime — Shikoku
Shikoku's finest earthwork mountain castle — twelve compounds and extensive horikiri networks in exceptional preservation in western Ehime's mountains.
