Kofu Castle Ruins (Maizuru Castle Park) — What Is It?
The Kofu Castle ruins (Kofu-jō ato) are a historic castle site located in Kofu City, Yamanashi Prefecture, now maintained as Maizuru Castle Park.
After the fall of the Takeda clan, construction proceeded under orders from Toyotomi Hideyoshi, and later the castle became an important base for Tokugawa rule over Kai Province.
Today, well-preserved remains—especially the stone walls—remain, and buildings such as the Inari Yagura, Tetsu Gate, and Yamate Gate have been reconstructed.
It was designated a National Historic Site in 2019 and was also selected as one of Japan’s Top 100 Castles (No. 25).
Maizuru Castle Park is loved by residents and visitors alike as a nature-rich park that preserves the castle ruins.
In spring the cherry blossoms bloom in profusion, making it a popular spot for hanami (flower viewing).
From the park you can also overlook Kofu city and, on clear days, see Mount Fuji in the distance—making it a special place where history and nature blend.
