String geometry theory is one of the candidates of nonperturbative formulation of string theory. In this paper, we have shown that dimensionally reduced string geometry theories have what we call T-symmetry. In the case of the dimensional reduction in space-like directions, the T-symmetry transformation gives the T-dual transformation between the Type IIA and IIB perturbative vacua. In the case of the dimensional reduction in the direction of string geometry time τ¯, the T-symmetry transformation is independent of the T-dual transformation and gives a symmetry that cannot be seen in the perturbative string theories.
