The star-shaped fort, 'Goryokaku Fort Ruins,' is designated as a Special National Historic Site. It was the stage for the Battle of Hakodate, the final battle of the Boshin War. Goryokaku became the final stronghold for the former shogunate forces led by Enomoto Takeaki and Hijikata Toshizo. It is generally known and beloved by the name Goryokaku Park. The reconstructed Hakodate Magistrate's Office is also a highlight.

In spring, it is a famous spot for cherry blossoms, and in winter, illuminations adorn the area around the moat. Currently, about 1,500 trees blossom here. When the petals fall, you can also see 'hanaikada' (flower rafts), where the moat's surface is completely covered in petals, offering a different kind of charm from when the flowers are in full bloom. Around the long holiday period, it is bustling and crowded with citizens gathering for cherry blossom viewing. In addition to cherry blossoms, flowers such as wisteria, azaleas, and water lilies are also magnificent.

The outer perimeter of the moat is a promenade of about 1,800 meters, and many citizens can be seen enjoying jogging and walking. In winter, snow accumulates on the frozen moat, creating a world of subtle and profound beauty. Goryokaku Park offers beautiful scenery in every season. When you visit Hakodate, please take your time to stroll through the park.
