Micron Technology Inc. has confirmed a major capital investment of $9.6 billion to build a new advanced semiconductor plant in western Japan. The facility will be fully dedicated to manufacturing high-bandwidth memory (HBM) chips, which have become essential to powering next-generation artificial intelligence systems.

Japan’s government has launched a broad strategic initiative to revive its semiconductor industry, allocating approximately $36 billion since 2021 to strengthen its industrial capabilities and reclaim its global position in the chip sector amid growing geopolitical risks and intensifying international competition.

Micron will receive $3.2 billion in direct financial support from Japan’s Ministry of Economy, Trade and Industry, part of a national plan to attract strategic investments and bolster technological security. This aligns with Japan’s support for major global projects involving companies such as TSMC and Rapidus, aiming to build a fully integrated local semiconductor ecosystem.

Demand for HBM chips continues to surge as AI adoption accelerates worldwide. Industry leaders including Nvidia, OpenAI, and Meta rely on these advanced memory solutions to boost the training and performance of high-capacity AI models. Competition remains fierce, with SK Hynix and Samsung Electronics fighting to expand their share in this rapidly growing market.

Construction of the new facility in Hiroshima is expected to begin in May, with commercial production scheduled for 2028. This long-term investment strengthens Micron’s manufacturing footprint in Asia and supports rising global demand for AI-driven semiconductor technologies.
