Japan lasers in on India's Assam state for chip and infrastructure corridor

Japan's push into Assam signals a strategic supply chain recalibration away from Taiwan Strait exposure. This move seeds India’s nascent semiconductor ecosystem—particularly in assembly, test, and power devices—but chronic shortages in skilled labor and unstable utilities could inflate Japanese operational costs by over 20%. Taiwanese and Korean foundries face near-term order leakage, likely accelerating TSMC’s capacity ramp in the U.S. and Europe. Within 18 months, if Japan and India secure exemptions on semiconductor equipment export controls, it would materially dilute the U.S.-led tech containment perimeter against China. More than an investment, this marks the inflection point where global chip geopolitics shifts from ‘Strait dependency’ to ‘multipolar redundancy.’
