The center's name changed from Tomakomai Youth Center to Tomakomai Science Center in November 1985, when the city museum opened and the science section was expanded. Its Mir display hall opened in December 1999. Visitors can see a former Hokkaido Police Fuji Bell 204B-2 helicopter named Hamanasu and a Datsun Baby, alongside a planetarium and amateur radio station.
