What Is Ōzu Castle? Highlights of Its Wooden Reconstructed Keep
Ōzu Castle (Ōzu-jō) is a historic castle located in Ōzu City, Ehime Prefecture, and a symbol of the "Little Kyoto of Iyo" rising on the banks of the Hijikawa River.
It is said to have been originally built in 1331 (Genkō 1, late Kamakura period) by Utsunomiya Toyofusa, the shugo (military governor) of Iyo Province, and was later developed into an early modern castle through renovations by Tōdō Takatora and Wakisaka Yasuharu.
The keep was dismantled in 1888 due to deterioration, but in 2004 it was restored through the passion and donations of local residents as Japan's first postwar four-tier, four-story wooden reconstructed keep.
Reaching 19.15 m above the stone walls, this keep was faithfully reconstructed based on old photographs from the Meiji era and an Edo-period wooden framework model known as the "tenshu hinagata," preserving castle-building techniques for the present day.

Highlights of Ōzu Castle
1. Japan's First Postwar Four-tier, Four-story Wooden Reconstructed Keep
The keep of Ōzu Castle was faithfully rebuilt using traditional construction methods based on historical documents.
This reconstruction, realized under an exemption from the Building Standards Act, attracted nationwide attention as a major citizen-participation project.
Inside the keep, visitors can closely observe traditional wooden joinery techniques without nails and the open atrium structure, experiencing the atmosphere of Edo-period castle architecture in a realistic way.
The Daidokoro Yagura and Kōran Yagura turrets connected to the keep are Important Cultural Properties that have survived since the Edo period, and the contrast with the reconstructed keep is another highlight.
2. Harmony with the Scenery of the Hijikawa River
Ōzu Castle stands on a small hill along the Hijikawa River, where visitors can enjoy scenery that harmonizes beautifully with nature.
The view of the keep looking up from Hijikawa Bridge and the embankment area is especially spectacular, making it a popular viewpoint for photography enthusiasts.
3. Seasonal Scenery Throughout the Year
- Spring (late March to early April): Cherry blossoms bloom in full, creating beautiful scenes of the castle and sakura together.
- Summer: The castle area is lush and green, and the traditional cormorant fishing on the Hijikawa River is also held from June to September.
- Autumn (mid-November to early December): Fall colors decorate the castle grounds, making walks even more enjoyable.
- Winter: The castle standing in quiet stillness has a deep charm, and the "Hijikawa Arashi" river fog rising from the Hijikawa is also magical.
