The open-air museum celebrates the friendship between Japan and the state of Minas Gerais and what this relationship was able to construct concrete and immaterial. The design is a bridge over a lake. The bridge metaphorically connects territories, times, ideas and ideals. The lake is like the sea between the nations, and also the one of the challenges, of the conquests, of the lived times. Actions and works become visible through striking dates that emerge in the water, and the submerged spaces represent the regions of the unconscious of feeling and memory.
