Experimental phenomenology is a fundamental procedure of scientific research, not using any special tool or machine but by simple, direct and precise observation. Shiro Morinaga was a great experimental phenomenologist on visual perception in Japan and famous by his many extraordinal articles. For instance, on the illusion of concentric circles (Delboeuf areal illusion), he noticed that the largest illusionary effect has been produced when the ratio of the diameter of two circles was at the 3:2 ratio and pointed out that "assimilation-contrast effect" is arranged if two circles are perceived as one pattern or two dissociate parts. The author who has believed the manner of investigation of Morinaga, from the standpoint "visual space is essentially tridimensional and changing constantly," demonstrated that the perception of a cube is firstly materialized by 6 planes, next by 8 points and 12 straight lines, by observation of the rotating 6 random-dotted planes. Tridimensional object is not completely perceived from a fixed viewpoint, but by total movement of an object.
