Since 1889, a volunteer group set approx. 2000 light bulbs around the moat of the Goryokaku Park. The light is lit from December 1 through February 28 of this year. If you go up the observatory floor of the Goryokaku tower which stands by the park, you can see a large star emerged in the dark earth.
