In this talk, a gravitational instanton means a hyperK\"ahler 4-manifold with the finite integral of curvature squared. The Torelli-type theorems were known for K3 surfaces, ALE, ALF, ALH gravitational instantons. In this talk, we will discuss the recent progress as well as potential ways of future research about the Torelli-type theorems for ALG, ALG^*, and ALH^* gravitational instantons.
