The fort was designed using French military architecture principles to minimize blind spots for artillery defense.
It was the first Western-style fortress built in Japan.
The Magistrate's Office was dismantled in 1871 and only reconstructed in 2010 based on historical blueprints.
The shape of the fort is only clearly discernible from an elevated vantage point, such as the adjacent Goryokaku Tower.
During winter, the moat is illuminated in a display known as 'Hoshino Yume' to highlight the star shape.
Goryokaku Park is a massive star-shaped Western-style fortress constructed by the Tokugawa Shogunate in 1864. The park occupies the interior of the defensive moat and earthen ramparts that define the unique star geometry. It served as the final battleground of the Boshin War during the 1869 Battle of Hakodate. The site is planted with over 1,500 cherry trees, making it a prominent destination for hanami. At the center of the fort stands the reconstructed Hakodate Magistrate's Office, restored using original architectural techniques. The moat remains filled with water, encircling the inner grounds. The park functions as a public space with walking paths that follow the perimeter of the inner citadel.

Visit the Goryokaku Tower observatory first to view the geometric star shape before exploring the park grounds on foot.
Wear comfortable walking shoes, as the paths circling the inner moat involve uneven terrain and significant walking distance.
Check the local cherry blossom forecast, as peak bloom typically occurs in late spring and significantly impacts crowd levels.
Do not expect to see the 'star' shape from inside the park; it is only visible from the air or the adjacent tower.
The inner Magistrate's Office has specific entry protocols; the park grounds themselves are generally accessible year-round.
Stay on marked walking paths; refrain from climbing on the earthen ramparts or stone walls to protect the historical structure.
