The roof also has an observation tower with spectacular views over the city.
The Japanese have achieved the dual goal of erecting a stadium to withstand harsh winter conditions and ensuring the grass continues to grow for the big football occasions.
Grass is kept outside in natural light until match day, when a stadium wall opens up, seats normally arranged for basketball slide back, and the pitch hovers into the stadium on jets of compressed air.
The Dome looks small for a game of the magnitude of England against Argentina, and the true test of whether it provides the right atmosphere for such a showpiece will only be revealed on Friday.
Perfect for spectators
The movement of the pitch into the arena takes about two hours, and is supported by 34 wheels as well as the pressure of the compressed air.
Views inside the stadium are perfect from every angle, with its array of black seats adding to the dramatic effect.
And climatic conditions are perfect for spectators as well as players, with the stadium being fitted with a giant air conditioner.
Heaters are employed in the freezing conditions that hit this part of northern Japan in the winter.
England will play to a packed house when they meet Argentina in Sapporo - hoping they can use the stadium of the future to shape a long-term stay at the World Cup.
