The city promotes urban development with the slogan: Ashibetsu, the village where the stars fall (a motto that also appears in the city’s emblem - 星の降る里 あしべつ). This is the reason for the series of caps with constellations on them.
The current lid symbolizes the constellation Gemini, a group named after the twins from Greek mythology Castor and Pollux, one mortal and one son of Zeus. The two stars that appear on the lid are Castor and Pollux
Additional constellations found on the site: Orion
Sagittarius
Translation of the text on the cover: 星の降る里、あしべつと - Ashibetsu, the village where the stars fall
