Ozu Castle

historyOff the trail — and worth it

A castle in western Ehime where the tall keep is a modern timber rebuild and the small turrets beside it are the Edo-period survivors. Below the hill, the old castle-town lanes are free and open at any hour.

The sweet spot

This is a well-known castle in Ehime, not a forgotten ruin. What visitors tend to miss is the order of the day. The lanes below the hill cost nothing and have no opening time, so the calm part of a visit here happens to be the free part.

How to actually get there

Matsuyama Station → Iyo-Ozu Station (JR Yosan Line, limited express Uwakai).
Iyo-Ozu Station → Ozu-jo-mae stop (Gururin Ozu town loop bus), or by taxi.
Ozu-jo-mae → the main bailey and the wooden keep, on foot up the hill.
Keep → Ohanahan-dori → Garyu Sanso, walking east through the old castle town.

JR limited express from Matsuyama, then the town loop bus: Matsuyama Station →(JR Yosan Line, limited express Uwakai)→ Iyo-Ozu Station. The rail leg runs well under an hour and limited expresses work through the day. At Iyo-Ozu, pick up the Gururin Ozu town loop bus for the Ozu-jo-mae stop, or take a taxi from the forecourt. Have cash ready for the bus.
Back toward Matsuyama from Iyo-Ozu: Return to Iyo-Ozu Station on the loop bus or on foot, then take the limited express back up the line. Read the loop bus times at the stop before you set out, not after; if the service has finished for the day, the station is still within walking distance of the castle town.

About the place

Ozu Castle stands on a low hill on the inside of a bend in the Hijikawa river, in western Ehime. The keep at the top is a wooden reconstruction, raised with traditional joinery rather than poured concrete. Ringing it are four turrets that came through from the Edo period, all designated Important Cultural Properties. The split is worth noticing: the protected buildings are the modest ones at the edges, while the tall one at the centre holds no such status. That is also why it can be used in ways a protected building cannot, including nights spent inside it under an official castle-stay programme.

How to enjoy it

The keep opens at 9:00 and closes at 17:00, so build the day around that window. Get there earlier and the free half of Ozu is already waiting — walk Ohanahan-dori and the riverbank first, then climb when the gate opens. Saving the keep for last also means finishing at the highest point, with the river bending below.

Background & history

A fortress first went up on this hill around 1331, under Utsunomiya Toyofusa, when the site was called Jizogatake. The Kato family took over in 1617 and governed Ozu for the rest of the Edo period. Meiji-era dismantling removed the keep and left only the turrets on the hilltop. A residents' fundraising drive eventually paid for a timber reconstruction, and the new keep was completed in 2004.

Before you go

Cash: The keep and Garyu Sanso are both ticketed, and a combined ticket covering the two is sold. Rates change, so check at the window rather than planning around a figure. Ohanahan-dori and the riverbank cost nothing and have no closing time. Carry cash for the town loop bus.
Good to know: The keep keeps daytime hours only, and inside it is bare timber with steep flights between floors. The castle-town lanes have no gate and stay walkable after dark, though some stretches are poorly lit. The climb to the main bailey is short but pitched.
Another way: From the south, JR Yosan Line trains also reach Iyo-Ozu from the Uwajima direction, so the castle drops neatly into a run between Matsuyama and the far southwest of Ehime rather than needing a trip of its own.
After you get off: From Iyo-Ozu Station the castle hill lies southwest, across the flat of the town. The simplest approach is the Gururin Ozu town loop bus to the Ozu-jo-mae stop, which leaves a five-minute climb to the main bailey.
