Tower Facilities
The pentagonal two-story observation deck offers 360-degree views of the city of Hakodate, Mount Hakodate, the Tsugaru Straits, and Hakodate Bay.
The second observation deck features the Goryokaku Historical Corridor, a permanent exhibit featuring dioramas related to Goryokaku, including the arrival of Perry to Hakodate and the Battle of Hakodate.
There is also a "Goryokaku reconstruction model (1/250 scale)" that reconstructs Goryokaku as it was when it was built, and a bronze seated statue of Hijikata Toshizo, who was known as the "devil's second-in-command" of the Shinsengumi.
Goryokaku
Goryokaku is one of the few Western-style castles built by the Tokugawa Shogunate at the end of the Edo period for the purpose of defending the Ezo region (present-day Hokkaido).
It consists of a star-shaped structure surrounded by a water moat and one half-moon fort, inside of which buildings such as the magistrate's office were constructed.
