A Samurai Stronghold in the Heart of Kofu
Standing on a small hill in central Kofu City, the Kofu Castle Ruins (舞鶴城跡, Maizuru-jō ato) are a reminder of the city’s important role during Japan’s feudal era. Once a strategic stronghold for the Tokugawa shogunate, the castle served as the political and military center of the region.
While the original wooden structures have long disappeared, the impressive stone walls, gates, and reconstructed turrets give visitors a clear sense of its former scale and power. Today, the site has been transformed into Maizuru Castle Park, a peaceful public space with panoramic views and seasonal charm.
History of Kofu Castle
Kofu Castle was built in the late 16th century under the orders of Tokugawa Ieyasu, following the defeat of the powerful Takeda clan. The location was chosen for its strategic advantage, a hilltop position with wide visibility over the Kofu Basin and surrounding mountains.
The castle became the seat of the Kofu Domain and played an important role in controlling the central region of Japan. Although many structures were dismantled in the Meiji period, the remaining stone walls are among the most impressive in Yamanashi.
Exploring Maizuru Castle Park

A visit to the castle ruins is as much about the scenery as it is about the history. Walking through the park, you’ll pass through large stone gates, climb sturdy staircases, and see panoramic views from the reconstructed Yamanote Gate and Inari Yagura turret.
From the top of the central keep’s foundation, visitors can enjoy 360-degree views of Kofu City, the Southern Japanese Alps, and even Mount Fuji on a clear day.
Seasonal Highlights

- Spring: The park becomes one of Kofu’s best cherry blossom viewing spots. Pink petals contrast beautifully against the grey stone walls.
- Summer: Lush greenery surrounds the castle, offering a cool retreat in the city.
- Autumn: Maple trees around the ruins turn vivid shades of red and orange.
- Winter: Clear skies provide excellent mountain views, especially of snow-capped peaks.
Cultural Events and Illumination
