Goryokaku is a bastion-style castle in the shape of a star. The star shape was invented in medieval Europe and is an advantageous shape for defense. There are only two Goryokakus in Japan: Goryokaku in Hakodate and Goryokaku in Tatsuoka Castle in Saku City, Nagano Prefecture.

Goryokaku was the site of the Hakodate War, the final battle of the Boshin War. In the Hakodate War, the new government forces and the former Shogunate forces fought fiercely, resulting in many casualties.

A popular tourist route is to view the magnificent star shape from the observation deck of Goryokaku Tower. In particular, in spring, about 1,600 Somei-yoshino cherry trees bloom in full bloom, and the view of the cherry blossoms colored in a star shape is overwhelming, attracting many cherry blossom viewers. In winter, the moat freezes over and snow piles up on top of it, making the star shape even more striking, allowing you to enjoy the beautiful snow scenery.
