9. Why Japan Hasn’t Produced Global IT Giants: Hegemony Structures & Organizational Culture

Economist Emin Yilmaz explains why Japan has failed to nurture massive IT platforms, analyzing the issue through the lenses of “hegemonic structures” and “domestic digital demand.” He notes that China is the only country outside the U.S. to ride the digital revolution wave, attributing this to its unique combination of massive market scale and deliberate exclusion of American services. Yilmaz argues that Japan and Europe’s reliance on existing U.S. platforms stems not from a lack of technical capability, but from geopolitical and economic hegemony. He also highlights issues like organizational homogeneity and internal friction, advocating for structural reforms as essential to fostering true innovation.
