What Is Kitsuki Castle? The Gateway to Exploring the Castle Town
Kitsuki Castle (Kitsuki-jō, also written Kizuki-jō) stands on a hill at 16-1 Ōaza Kitsuki, Kitsuki City, Ōita Prefecture, in a scenic spot overlooking Moriegawa Bay.
Originally built in 1394 (Ōei 1), the castle has a long history, and the current structure is a reconstructed mock tenshu (castle keep) built in 1970 (Shōwa 45).
Inside, historical materials are on display, including the armor used by the feudal lords and a Bungo plum jar.
Kitsuki Castle is both a place to enjoy the view and an easy entry point into the history of Kitsuki.
If you are walking through Kitsuki for the first time, rather than diving straight into the slopes, starting at Kitsuki Castle to grasp the town's background will make your subsequent castle town stroll easier to understand.
By first taking in the castle's location overlooking the sea and the spread of the castle town below, you'll find it easier to picture how the town is laid out.
Highlights to Look For at Kitsuki Castle
- Views of Moriegawa Bay and the Kitsuki city area from the keep
- Historical exhibits including armor and a Bungo plum jar inside the castle
- A location that connects naturally to the castle town walk after your visit
- The scenery of Shiroyama Park in spring, with about 250 cherry trees in bloom

Top Things to See at Kitsuki Castle: Quiet Views and Historical Exhibits
The charm of Kitsuki Castle lies less in flashy attractions and more in the chance to quietly take in scenery and history.
From the keep, looking out over Moriegawa Bay helps you naturally appreciate why the castle was placed in such a naturally fortified setting, surrounded by the sea and cliffs.
Inside the castle, you'll find materials connected to the lords of the domain, such as armor and a Bungo plum jar, which give you a feel for the atmosphere of the Kitsuki Domain.
The exhibits themselves are compact, with a recommended visit time of about 20 to 30 minutes.
You can tour the castle quickly, but stepping outside again after viewing the exhibits will help you see the relationship between the castle and the town in a more three-dimensional way.
Making the Most of the View Beyond Photo Spots
When taking photos, it's a good idea to look intentionally toward the sea, the town, and the slopes.
Heading to Suya no Saka (Suya Slope) afterward, you'll feel how the elevation differences seen from the keep connect to the actual experience of walking through the town.

Suya no Saka: Where the Shape of Kitsuki Castle Town Becomes Clear
Suya no Saka is a sloping street that connects the samurai residences of Kitadai (the northern hill) with the merchant town in Tanimachi.
Across Tanimachi, on the opposite side, lies Shioya no Saka (Shioya Slope), and Suya no Saka and Shioya no Saka facing each other create a unique landscape known as a "sandwich-style castle town," linking the samurai districts of Kitadai and Minamidai (the southern hill) through the merchant town in between.
The slope's name is said to come from a vinegar merchant (suya) who once ran a shop at the bottom of the hill.
When walking Suya no Saka, paying attention to the layered combination of stone pavement, earthen walls, and stone walls makes the experience much more memorable.
Rather than passing through it as a mere walking route, sensing how the samurai district and the merchant district were connected makes the unique charm of Kitsuki's landscape clearer.
Why You Should Visit Suya no Saka After Kitsuki Castle
By heading to Suya no Saka after seeing Kitsuki Castle, the structure of the castle town — the elevated castle, the slopes, the samurai residences, and the merchant district — becomes much easier to grasp.
The Kitsuki Castle Town Museum (Kitsuki Jōkamachi Shiryōkan) features 3D models showing the unique terrain and structure of Kitsuki's castle town. If you have time, visiting the museum together with the castle will deepen your understanding.

Easy First-Time Itinerary: Connecting the Castle to the Slopes

After enjoying the view from the keep, heading down to the slopes lets you actually feel the elevation differences and the layout of the town as you walk.

Things to Keep in Mind While Walking
- Watch your step on stone pavements and slopes
- Be quiet when passing near homes and earthen walls
- Choose photo spots that don't block other walkers
- In summer, bring a hat and drinks to stay comfortable in the strong sunlight
Seasonal Highlights
In spring, the cherry blossoms at Shiroyama Park reach their peak from late March to early April, allowing you to enjoy the view of the keep alongside the cherry blossoms.
In autumn, from mid to late November, the calm atmosphere of the castle town becomes especially enjoyable.
The charm of Kitsuki is that it can't be summed up by visiting only the castle.
By experiencing the castle, the slopes, and the streetscapes in succession, you can appreciate the historical landscape around Kitsuki Castle far more naturally.
Summary

And by walking onward to Suya no Saka, you can see and understand the unique terrain on which the castle town was built.
Don't end your visit at the castle alone — keep walking to the slopes and streetscapes.
That is the easiest way, even for first-time visitors, to fully enjoy Kitsuki Castle.
