The Dome switches between two entirely different surfaces: Baseball games are played on an underlying artificial turf field, while football games are held on a grass pitch that slides into and out of the stadium as needed.

Conversion from baseball to football begins with the storage of the baseball field's artificial turf.
 Once finished, a set of lower bowl bleachers rotate from an angled position for baseball to a parallel position.
 A set of main bowl seats on one end of the dome then retracts, and the football pitch is slid into the stadium.
 The lower bowl is then rotated 90 degrees.
 Conversion from football to baseball occurs in reverse.
Due to the retraction of seats, the Stadium has a capacity of 40,476 for baseball games.

Other stadiums that feature sliding pitches include the GelreDome in the Netherlands, Veltins-Arena in Germany, the split pitch of London's Tottenham Hotspur Stadium, and State Farm Stadium in Glendale, Arizona, United States; however, unlike these four facilities, the Sapporo Dome has a fixed roof.
