What Are the Kofu Castle Ruins (Maizuru Castle Park)? Kofu’s Symbol Just Steps from the Station
Kofu Castle Ruins (Kōfu-jō Ato) is a historic castle site in Kofu City, Yamanashi Prefecture, now maintained as Maizuru Castle Park (Maizuru-jō Kōen).
After the fall of the Takeda clan, construction progressed in the late 16th century by order of Toyotomi Hideyoshi, and the castle later became a key base for governing Kai Province under Tokugawa rule.
Today, well-preserved remains centered on impressive stone walls can be seen, and structures such as Inari Yagura, Kurogane-mon Gate, and Yamanote Gomon Gate have been reconstructed.
In 2019 (Heisei 31), it was designated as a National Historic Site and also selected as one of Japan’s Top 100 Castles (No. 25).
Along with preserving the castle ruins, Maizuru Castle Park is loved by locals and visitors as a green public park.
In spring, about 160 cherry trees bloom around the stone walls, making it a famous hanami spot.
From the tenshudai (main keep base), you can enjoy a 360-degree view over the Kofu Basin, with vistas of Mt. Fuji and the Southern Alps recognized as one of the “Kanto Fuji-view 100 Scenic Views.”
Another major advantage is its excellent location—only about a 3-minute walk from JR Kofu Station.

Top Things to See at Kofu Castle Ruins (Maizuru Castle Park)
1. The Beauty of the Grand Stone Walls
Kofu Castle’s stone walls are valuable remains that convey the high level of castle-building techniques of the time.
A key feature is that you can see multiple masonry methods, including nozura-zumi (rough stacking using natural stones) and kirikomi-hagi (tight-fitting cut-stone masonry).
The stone walls of the tenshudai are especially impressive in both height and scale, and the “Kyōdai-ishi (Twin Stones),” where a single stone was split and stacked to the left and right, is another highlight.
2. Reconstructed Inari Yagura and Kurogane-mon Gate
Inari Yagura is a wooden structure reconstructed in 2004 (Heisei 16) and is open to the public inside as an exhibition room.
You can view roof tiles and ceramics excavated in archaeological surveys, as well as a miniature model of Kofu Castle.
The reconstructed Kurogane-mon Gate has an imposing presence and is a popular photo spot that evokes the castle’s former grandeur.
Both can be visited free of charge.
3. A 360-Degree Panorama from the Tenshudai
From the tenshudai at the highest point of Maizuru Castle Park, you can overlook the entire Kofu Basin.
On clear days, Mt. Fuji appears to the south and the Southern Alps to the west, and in winter’s crisp air the view can be breathtakingly beautiful.
Don’t miss the Kofu Basin tinted orange at dusk, either.
4. Seasonal Scenery
- Spring (late Mar–early Apr): About 160 cherry trees color the entire park, and the pairing of stone walls and sakura draws crowds as a beautiful hanami spot.
- Summer (Jun–Aug): Lush trees envelop the park, making it ideal for a stroll.
- Autumn (Oct–Nov): Fall foliage vividly colors the stone walls and park scenery.
- Winter (Dec–Feb): With clear air, it’s the best season to enjoy Mt. Fuji views from the tenshudai.
5. Night Illuminations
Maizuru Castle Park is sometimes illuminated at night, with the stone walls and Kurogane-mon Gate lit in a magical glow.
Illuminations during cherry blossom season are especially unmissable, offering a dreamlike scene of night sakura and stone walls.
