U.S. chipmaker Micron Technology is reportedly investing 1.5 trillion yen (about $9.6 billion) to build a new advanced memory-chip factory in Hiroshima, Japan. The facility will produce high-bandwidth memory (HBM) chips designed to meet surging demand from artificial-intelligence infrastructure and data-center growth. Construction is slated to begin in May 2026 at an existing site, and shipments are expected to start around 2028. The project will be supported by up to 500 billion yen in subsidies from Japan’s Ministry of Economy, Trade and Industry. Observers view the move as part of a broader effort by Tokyo to revitalize its semiconductor industry and reduce regional concentration of chip manufacturing in Taiwan.

Key Takeaways
– The planned investment of roughly $9.6 billion represents a major escalation for Micron — signaling a belief that demand for AI-related memory chips will remain strong well into the future.
– Japanese government backing, in the form of substantial subsidies, underlines Tokyo’s strategic push to rebuild its semiconductor manufacturing base and reduce dependence on foreign supply chains — notably in Taiwan.
– By producing HBM chips in Japan, Micron aims to diversify production geographically and strengthen its competitive position against rivals such as SK Hynix, while tapping growth in data-center and AI infrastructure markets.
In-Depth
The announcement that Micron Technology plans to invest 1.5 trillion yen (about $9.6 billion) to build a next-generation memory plant in Hiroshima lays bare the rapid transformation underway in the global semiconductor industry. The planned facility is to produce high-bandwidth memory (HBM) chips — a critical component in powering artificial-intelligence (AI) workloads and modern data centers. With construction targeted to begin in May 2026 at an existing Hiroshima site, and shipments projected around 2028, Micron is clearly placing a long-term bet on sustained demand for AI infrastructure.
The scale of the commitment speaks volumes. At this magnitude, Micron is signaling confidence not simply in the AI boom of the moment, but in the long-term structural shift toward compute-heavy workloads requiring advanced memory — from large language models to cloud-based processing. For investors, this suggests that memory chips are no longer a cyclical commodity anchored to consumer electronics, but instead a core backbone of enterprise AI ecosystems.
For Japan, the project dovetails neatly with Beijing/Beijing’s growing unease about supply-chain concentration and resilience. Tokyo — through its Ministry of Economy, Trade and Industry — is offering up to 500 billion yen in subsidies to support the plant, underscoring a national strategic push to rebuild domestic semiconductor capacity. This not only reduces Japan’s vulnerability to overseas supply disruptions, but also strengthens a regional manufacturing hub outside of Taiwan and South Korea.
That shift carries competitive implications. For Micron, manufacturing HBM in Hiroshima offers a hedge against geopolitical risk and supply-chain bottlenecks that have long plagued semiconductors. It also allows the company to better contest rivals such as South Korea’s SK Hynix in supplying memory for AI servers worldwide. Given the urgency many data-center operators now feel to secure long-term memory supply, Micron may gain pricing leverage, improved margins, and arbitrage relative to those relying on memory from now-overburdened foundries in Taiwan.
However, the plan is not without risk. Execution will take years — with actual shipments not until 2028 — and much can change in the AI hardware landscape in that time. Technological breakthroughs, alternative memory architectures, or shifting demand could undercut the economics. Additionally, despite government support, building and ramping such an advanced facility is capital-intensive and operationally complex.
Still, this move by Micron offers a clear signal: memory chips are rising in strategic importance. For governments, that may mean new subsidies and industrial policy. For data centers and AI firms, it underscores the value of locking in reliable supply. And for investors, it reinforces the case that companies enabling AI infrastructure — not just AI software firms — may deliver strong returns in the years ahead.
