Marugame Castle Travel Guide: Towering Stone Walls and an Original Keep
Marugame Castle in Marugame City, Kagawa Prefecture, is a hilltop castle built on Mt. Kameyama, where you can enjoy both the curves of its towering stone walls and the figure of its surviving wooden keep.
Walking the castle grounds reveals not only the structures built to defend the castle but also the skill of the craftsmen who stacked the stones and the connection to the castle town.
Construction began in 1597 (Keichō 2) under Chikamasa Ikoma and his son Kazumasa, and the keep was later completed under the Kyōgoku clan, conveying more than 400 years of history to this day.
Marugame Castle's Highlights Begin with Its Towering Stone Walls
Marugame Castle is so strongly defined by its stone walls that it is sometimes described as a "castle of stone."
On the north side of the Sannomaru (third bailey), walls more than 20 meters tall continue, and their height and curves leave a strong impression of the castle.
As you proceed from the Ōtemon (main gate) side up the hill, the height and curve of the stone walls change, and even within the same castle the character of the views shifts little by little.
See One of the Twelve Surviving Keeps Up Close
The keep is one of only twelve original keeps remaining nationwide, conveying its trim three-tiered, three-story form to this day.
At about 15 meters high, it is the smallest among the surviving keeps, but the white walls and overlapping roofs, along with the placement of the karahafu (curved gable) on the first tier and the chidorihafu (triangular gable) on the second, leave a lasting impression.
The compact sense of mass perched atop the stone walls is also a highlight unique to Marugame Castle.
Easy to Combine with a Stroll Through the Castle Town
Marugame Castle is close to the city center, about a 10-minute walk from JR Marugame Station, making it easy to move on to a town walk after seeing the castle.
Without leaning too heavily on history alone, it is an easy spot to use as a base for a trip that engages with local culture, such as Sanuki udon, honetsuki-dori (bone-in grilled chicken), and Marugame uchiwa (round fans).
To Appreciate Marugame Castle's Stone Walls, Focus on the Slope and Stacking Method
You'll understand Marugame Castle's stone walls more deeply by not only looking up from below but also stepping closer to see the shapes of the stones and how they are assembled.
Even what looks like the same stone wall uses different techniques and serves different roles depending on the spot, so knowing a few names adds to the joy of walking.
Look Up at the "Fan-Shaped Slope" from Below on the North Side of the Sannomaru
On the stone walls on the north side of the Sannomaru, you can take in the curving beauty called the "ogi no kobai" (fan-shaped slope), which grows steeper the higher it rises.
This graceful curve is said to have been created in the time of Yamazaki Ieharu, who rebuilt Marugame Castle in the early Edo period.
Up close, the mass of the stones is striking, while stepping back a little makes the beauty of the curve easier to appreciate.
See the Large Stones and Tooling Marks Around the Ōtemon
The area around the Ōtemon is the castle's main front entrance, where you can observe large stones and stones bearing chisel marks.
The size and finish of the stones are a highlight of the entrance, showing the castle's prestige even as a place of defense.
Turning your attention to the size and arrangement of the stones changes the impression of the masugata (boxed enclosure) space.
Spot the Difference Between Natural and Dressed Stone Faces
Depending on the location, you can see faces that suggest natural stone as well as faces where split, dressed stones are neatly stacked.
Comparing the dressed faces with the natural ones lets you sense the differing approaches to wall-building by era and place.
Look at the Reinforcement and Drainage Ingenuity Too
You can also note the reinforcements that protect the stone walls and the techniques of restacking stones to preserve them.
The stone walls also have drainage systems that channel away rainwater, letting you read not only their beauty but also the ingenuity that keeps the castle standing for the long term.
Knowing the stone-wall terms gives you a perspective for telling them apart as you walk.
| Term | What to Look For | Main Location |
|---|---|---|
| Stones with tooling marks | Stone finish | Around the Ōtemon |
| Large stones | Impact at the entrance | Around the Ōtemon |
| Natural-looking faces | Natural character | Parts of the walls |
| Dressed stones | Neat courses | Parts of the walls |
| Sangi-zumi | Strength of corners | North side of the Sannomaru |
| Reinforcing walls | Protective ingenuity | Around the stone walls |
Quietly Viewing One of the Twelve Original Keeps and the Important Cultural Property Ōtemon
At Marugame Castle, rather than making the keep your only destination, viewing it within the flow from the gate up the hill makes the castle's structure easier to grasp.
The number of surviving buildings is not large, but because the positional relationship between the stone walls, the gate, and the keep is clear, it is a castle where even first-time castle travelers can easily organize the highlights.
The Keep Looks Small and Trim Atop the Stone Walls
Marugame Castle's keep gains a commanding presence even from afar by sitting atop the hilltop stone walls.
The closer you get, the more the tension created by its combination with the stone walls comes through, rather than the size of the building itself.
View the Ōtemon as an Important Cultural Property Castle Entrance
The Ōtemon consists of the Ōte-ichi-no-mon, a yagura-mon (turret gate), and the Ōte-ni-no-mon, a kōrai-mon gate; both were built in 1670 (Kanbun 10) and are designated National Important Cultural Properties.
The Ōte-ichi-no-mon is also called the "Taiko-mon" (Drum Gate), and a time drum is still sounded there at noon.
When passing through the gate, being aware of the masugata space enclosed by stone walls and the zigzagging path designed to repel attackers makes the castle's defensiveness easier to understand.
The Genkansaki Gomon Is a Clue to Imagining the Lord's Life
The Genkansaki Gomon, a Kagawa Prefecture designated cultural property, lets you imagine that the castle was not only a military facility but also connected to the lord's daily life and governance.
It's easy to be drawn to the large keep and the tall stone walls, but pausing in front of the gate reveals the differences in roles within the castle.
The Scenery Changes with the Order in Which You Walk the Castle
Because Marugame Castle is a castle where you savor the scenery while climbing the slopes, making time to look back leaves a stronger impression than rushing ahead.
Watching your footing as you proceed from the gate to the slope, the baileys, and the keep naturally links the castle's defense and its views.
Enjoy Mikaeri-zaka by Looking Back
The slope leading up from the Ōtemon is called Mikaeri-zaka (the "looking-back slope"), where scenery unfolds that makes you want to glance back along the way.
Accepting the effort of climbing the slope as part of the castle experience deepens the sense of achievement when you reach the Honmaru (main bailey) at the top.
Change Your Perspective at Each Bailey
The baileys (kuruwa)—the Sannomaru, Ninomaru, and Honmaru—are arranged in stages, making use of Mt. Kameyama's terrain.
Each time you enter a bailey, the appearance of the stone walls, the openness of the surroundings, and the distance to the keep change, so the spots where you take photos naturally change too.
Organizing your perspective for each part of the walk turns it into a visit that is more than just climbing.
| Spot | What to Look For | Feeling |
|---|---|---|
| Around the Ōtemon | Castle entrance | Stepping into history |
| Mikaeri-zaka | Scenery looking back | The sense of climbing |
| Sannomaru | Curve of the walls | Reading the structure |
| Ninomaru | Spread of the grounds | Catching your breath |
| Honmaru | Keep and the view | Sense of arrival |
How Marugame Castle Looks Changes with the Season and Light
Because Marugame Castle combines stone walls, trees, and the white walls of the keep, its impression changes with the season and the direction of the light.
Even without timing your visit to a particular event, simply shifting the time you walk makes the shadows on the stone and the view of the town look different.
In Spring, Enjoy the Contrast of Soft Cherry Blossoms and Stone Walls
In spring, the atmosphere of the cherry blossoms and trees within the castle softens, and from late March to early April most years there is a contrast with the weight of the stone walls.
During crowded periods, choosing where to stop without blocking the paths lets you enjoy it calmly.
In Summer, Be Mindful of Shade and Rest
Since the slopes can be tiring in summer, proceeding while resting in the shade or in open spaces lets you tour without overexertion.
During the hours when strong light strikes the faces of the stone walls, the unevenness of the stones and the stacking method become easier to see.
In Autumn and Winter, the Lines of the Stone Walls Stand Out
From mid-November into December, some days have clear air, and the view of the keep and the castle town can feel crisp and clear.
The colors of the trees and the scenery glimpsed through the branches also make the lines of the stone walls and the outline of the gate easier to see, which is part of the appeal.
Knowing how it looks by season is also useful when thinking about photo composition.
| Season | How It Looks | How to Walk |
|---|---|---|
| Spring | Cherry blossoms and stone walls | Stop to take it in |
| Summer | Shade and slopes | Don't overdo it |
| Autumn | Light and shadow | Observe the curves |
| Winter | Clear views | Walk quietly |

Viewing Etiquette for Visitors to Japan
Marugame Castle is a tourist spot and at the same time a place that includes historic sites and cultural properties.
Whether taking photos or approaching the stone walls and buildings, keeping in mind not to damage what has been preserved for so long lets you spend your time with peace of mind.
Don't Climb the Stone Walls; Observe from a Distance
The stone walls are a highlight of the castle, but climbing on the stones or inserting objects into the gaps can cause damage.
When you want to see the details, view them from a distance and a spot that doesn't block the path.
Be Considerate of Others and Cultural Properties When Taking Photos
In places where photography is allowed, being mindful not to block the paths and not to prominently capture other visitors makes for a more comfortable time.
Before touching buildings, pillars, or exhibits, check the on-site signage.
Sorting the etiquette that's easy to second-guess into what you can do and what to avoid makes decisions easier.

|---|---|---|
| Photography | Leave the path clear | Occupying it too long |
| Viewing stone walls | View from a distance | Climbing the stones |
| Walking the slopes | Watch your footing | Running down |
| Before cultural properties | Read the signage | Touching without permission |
| Eating and drinking | Choose the place | Leaving trash |
Summary: Marugame Castle Is a Castle Trip Read Through Its Towering Stone Walls
Marugame Castle is a castle site you can enjoy not only through the silhouette of one of the twelve original keeps but also through the slope and stacking of the walls rising more than 20 meters on the north side of the Sannomaru, and the path from the gate to the Honmaru.
Proceeding from the Ōtemon up Mikaeri-zaka and heading to the Honmaru while comparing the stone walls at the Sannomaru and Ninomaru naturally conveys both the structures built to defend the castle and the changes in the scenery.
Rather than hurrying to see only the keep, first-time visitors can savor what makes Marugame Castle special more deeply by walking with a little awareness of the names of the stone walls and the roles of the baileys.
