Founded on January 23, 1962, and headquartered at Glass City Bldg, 30-13 Motoyoyogicho, Shibuya-ku, Tokyo 151-0062, Japan, the firm maintains neutrality as its stock remains primarily held by the founding family of Osamu Suga, enabling unbiased consulting independent of associations, contractors, or manufacturers.
