Minatoyama Park and Yonago Castle Ruins: What Is the Difference?
Minatoyama Park (Minatoyama Kōen) and Yonago Castle Ruins (Yonago-jō Ato) stand next to each other and are often presented as a single walking destination. However, the sights and walking conditions differ between the level waterfront park and the nationally designated historic site, where you climb Mount Minato (Minatoyama) to explore stone walls and the castle keep platforms.
Minatoyama Park: A Place to Relax beside Nakaumi
Minatoyama Park lies along Nakaumi near central Yonago. Walk its paths and green spaces while looking out over the water and sky, or enjoy everyday activities such as picnicking, strolling, and jogging.
Because Nakaumi was once called Kinkai, Minatoyama Park was also popularly known as Nishiki Park (Nishiki Kōen).
You can enjoy the park on its own even without climbing to the castle ruins. Looking up at Mount Minato's slopes and the stone walls above gives you a clear sense of how the park and ruins sit side by side.
Yonago Castle Ruins: A National Historic Site on the Hilltop
Yonago Castle Ruins are the remains of an early modern castle built on Mount Minato, approximately 90 m above sea level. Although no buildings survive, its stone walls and foundation stones clearly convey the castle's layout. The site was designated a National Historic Site in 2006.
The value of Yonago Castle Ruins lies in exploring how the stones were laid, the changes in elevation between enclosures, and the bends in the approach on foot, reading the entire hill as a castle, rather than in reconstructions that compensate for the absent keep.

Reading Yonago Castle's History through Its Stone Walls
Also known as Kume Castle (Kume-jō), Yonago Castle was built overlooking Yonago as it grew into a commercial center. It was not only a military stronghold but also a symbol of rule over a region where sea routes, rivers, and roads connected.
Construction Began around 1591
Hiroie Kikkawa began construction around 1591 (Tenshō 19), and Kazutada Nakamura, who later became the castle lord in Hōki Province, is said to have completed it around 1602 (Keichō 7). The castle's form reflects overlapping periods and the ideas of different rulers.
Rather than stopping after seeing the main enclosure on the summit, trace where people entered and which enclosures they passed through to reach higher ground. Walking this route helps you understand how an early modern castle combined defense with imposing presence.
The Buildings Are Gone, but the Layout Remains
The buildings were sold and dismantled in the early Meiji period, so the former keeps and turrets cannot be seen on site. However, the arrangement of stone walls, foundation stones, and level areas provides clues to where the buildings stood and how large they were.
When mentally reconstructing the missing keep, use the tops of stone walls and rows of foundation stones as reference points. This helps distinguish what the remains can establish from imagination, without relying too heavily on pictorial reconstructions.
Imagine the 2 Keeps Standing Side by Side
Yonago Castle had a 5-tier main keep and a 4-tier subsidiary keep (a 4-tier turret). The arrangement of several tall buildings on the hilltop is thought to have made a strong impression on people viewing the castle from afar.
Grouping the remains by their function makes it easier to know what to look for as you climb.
| Remains | What to Look At | Function to Imagine |
|---|---|---|
| Castle approach | Bends and slopes | Controlling movement |
| Stone walls | Corners and curves | Defending enclosures |
| Foundation stones | Rows and spacing | Building locations |
| Keep platform | Height and area | Symbol of the castle |

Discover Early Modern Castle Design on the Yonago Castle Approach
The walk from the foot of the hill to the keep platform takes approximately 15 minutes, but includes slopes and stone steps. Think of it as a walk with time to stop and study the remains, rather than a route to complete as quickly as possible.
Check Routes and Access Information at the Entrance
Before climbing, check your location, the keep platform, and descent routes on the on-site map. Look for current closures or maintenance notices so you can respond to temporary changes caused by construction, fallen trees, or similar issues.
Photographing the map lets you check it even where connectivity is unreliable. In the evening or during busy periods, you can also agree with your companions whether to retrace your route or descend to another exit.
Alternate between Watching Your Footing and the Stone Walls
Looking only upward as you climb can distract you from your footing. Look up at the walls from places where you can stop safely, then return your attention to uneven steps and wet fallen leaves when walking.
At the corners of the stone walls, notice how long stones alternate and how the surfaces curve. Rather than simply searching for large stones, imagine how they bear loads together to support the elevated enclosures.
Keep Your Distance and Do Not Touch the Cultural Properties
Do not climb the walls or move stones. Observe from outside protective barriers and marked restricted areas. This protects the remains and helps keep you and people walking below safe from falling rocks and falls.
Plants and insects also form part of the castle hill's environment. Stay on the paths rather than approaching them off-trail, do not collect them, and walk quietly through a place where history and nature are preserved together.

Read the 360-Degree View from Yonago Castle's Keep Platform by Direction
At the keep platform, the view opens out across Nakaumi, the Sea of Japan, central Yonago, and Mount Daisen as you turn around. Rather than fitting everything into 1 photograph, study the relationship between terrain and town in each direction for a deeper understanding.
Look East toward Mount Daisen and the City
To the east, Mount Daisen's ridgeline rises beyond the spread of Yonago. More intuitively than a map, this view shows how the castle lord could watch activity in the castle town and a mountain emblematic of the San'in region within the same panorama.
Even when clouds hide Daisen, following the directions of streets and buildings reveals the underlying layout of the plain that connects the old castle town with the modern city.
Trace Nakaumi and the Waterways to the West
To the west, Nakaumi's broad expanse of water stands out. Looking toward the opposite shore and Shimane Prefecture helps you see how Yonago's location supported its development through water transport and port connections as well as roads.
When reflections make the terrain hard to see, choose an angle that is safe to view with the naked eye. When using binoculars or a camera, take up a position well back from the edge underfoot.
Sense the Opening toward the Sea of Japan to the North
To the north, the view opens beyond the city toward the Yumigahama Peninsula and the Sea of Japan. It invites you to consider why the castle was placed on a hilltop overlooking both inland areas and the coast.
Organizing the views by direction before looking all the way around turns a beautiful panorama into evidence explaining the castle's location.
| Direction | Main View | Relationship to Read |
|---|---|---|
| East | City and Daisen | Castle town and mountain |
| West | Nakaumi | Water transport and the opposite shore |
| North | Toward Yumigahama | Opening toward the sea |
| Below your feet | Enclosures and stone walls | Castle layout |

Combine Your Walk with Minatoyama Park
Walking through Minatoyama Park before or after the climb lets you reconsider Nakaumi and the city from water level after viewing them from above. You can connect 2 experiences—the castle panorama and a park enjoyed by residents—in a single outing.
Change Your Perspective on the Nakaumi Waterfront Path
Along the waterfront path, the wind and sound of waves feel close at hand. You can see how Nakaumi, viewed from above at the keep platform, meets the city as part of everyday life and a place for walks.
The colors of the sky and water change around sunset, but avoid planning to descend the hill after dark. If you want to enjoy the evening view, the safer order is to descend first and watch from the park.
Plan for Crowds during Cherry Blossom Season
Minatoyama Park is a cherry blossom destination with approximately 500 Somei-yoshino cherry trees.
Many people visit Minatoyama Park in spring. Pay attention to the flow of pedestrians and cars as well as the flowers, and avoid blocking paths or the castle approach entrance while reserving a picnic spot or taking photos.
Event arrangements and lantern lighting may change from year to year. Do not rely on past schedules: check event information for your visit date and distinguish ordinary park areas from event zones.
Getting to Yonago Castle Ruins: Parking and What to Bring
Yonago Castle Ruins are approximately 20 minutes on foot or 5 minutes by car from JR Yonago Station. Whether walking, taking a bus, or driving, the site is close to the city center, but the final hill path must be climbed on foot.
Choose Your Starting Point Based on Where You Park
Yonago Castle Sannomaru Parking Lot accommodates 30 cars, while Minatoyama Park Parking Lot holds approximately 100.
The entrances and operating hours differ between Yonago Castle Sannomaru Parking Lot and Minatoyama Park Parking Lot. Do not rely solely on your navigation system's destination: check on-site signs for current access and the route to the castle approach.
Minatoyama Park Parking Lot has seasonal operating hours. Work backward to decide when to descend so you return before closing, and check which parking areas are available if you plan to visit early in the morning or for night views.
Bring Comfortable Shoes and Water
Even a short climb includes unpaved sections. Choose shoes with slip-resistant soles, expect wet stone steps and dirt slopes after rain, and bring rainwear that leaves your hands freer than an umbrella.
Visitor information states that there are no coin lockers on site. Leave large bags at the station or your accommodation, and carry only essentials such as water, a hat, and a small light on your back for a safer walk.
Plan to Descend While It Is Still Light
Although the evening view from the keep platform is appealing, hill paths grow dark earlier than city streets. Check sunset time and lighting for your footing; if you are unfamiliar with the route, prioritize returning to the park before dusk.
If sudden rain, strong winds, or access restrictions occur, do not insist on reaching the keep platform. Switching to a route that views the castle hill from Minatoyama Park or the city is a sensible way to keep enjoying historic-site walks over time.
Yonago Castle Ruins and Minatoyama Park: Walking Guide Summary
At Yonago Castle Ruins, following the stone walls, foundation stones, and enclosures reveals the structure of an early modern castle. Viewing Nakaumi, Daisen, the Sea of Japan, and the city by direction from the keep platform gives a fuller understanding of why the castle was placed on Mount Minato.
Check access information before visiting, wear comfortable walking shoes, and plan to descend in daylight. Adding a waterfront walk through Minatoyama Park before or after the climb lets you enjoy both a National Historic Site and a place where residents relax without overexerting yourself.
