Every year, from December 1st to the final day of February, Hakodate's historical fortress of Goryokaku is lit up in an event known as Hoshi no Yume.

Around 5000 lights are strung along the perimeter of the fortress, which was constructed during the waning years of the Edo Period (1600–1868) as a defensive measure against potential international incursions. The illuminations take place each evening and last from 5pm to 8pm. A path runs along the exterior of the star-shaped structure, making the site perfect for a post-dinner winter stroll, especially when the snow is falling.
