In this case, the upper part of the audience seat is covered with a roof to prevent rain.

  On the other hand, there is a stadium where natural grass is planted in the field. In order to cultivate this natural turf, long hours of sunshine are required. However, if there is a roof, the amount of solar radiation on the field surface is reduced. For this reason, rooftop stadiums with natural turf fields often employ open and close roofs.

  Then, the stadium which takes a field out of a stadium for natural turf curing and ensures sunshine is examined (for example, refer patent document 1). In the technique described in this document, a competition field in a covered stadium is transported outdoors when no competition is performed in the stadium, and natural grass is grown outdoors. In this case, a large site for nurturing natural grass is required near the stadium.

  Therefore, a technique for raising natural turf outdoors by raising the field of the stadium to the height of the fixed roof for natural turf curing has been studied (for example, see Patent Document 2). In the technique described in this document, the field is raised to the height of the fixed roof to grow natural grass planted in the field, and when the field is used, the field is lowered from the fixed roof to the ground.
