About us


Specialized in international companies and government agencies as their communications partners for over two decades, this New York-originated public relations firm has been blessed with the great clientele from Europe (Austria, France, Germany, Italy, Swiss and the UK), Asia Pacific (Australia, China, Hong Kong, Indonesia, the Philippines, Taiwan and Turkey), Latin America (Brazil, Chile and Mexico) and North America. This agency has been engaged in insightful consultation, strategic planning and professional implementation on their behalf, while serving as a steady, credible and critical communications conduit between them and their targeted audiences in Japan.

GCI SunPub was founded in 1992 as the Tokyo office of the GCI Group, a global communications firm, the public relations arm of Grey Advertising in New York. In 2008, when Grey was acquired by the world’s largest communications conglomerate, we parted from them to stay independent so that we have been carrying the same corporate name that had already been well recognized by the mass media and our international and domestic clients.
