Land leveling and site preparation have begun on a plot adjacent to the Micron Memory Japan Hiroshima plant, suggesting potential facility expansion to support mass production of advanced memory chips.
Context
Micron has initiated site preparation for a massive expansion at its Hiroshima facility, signaling progress on a planned 1.5 trillion yen ($9.6 billion) investment. Land leveling is currently underway on a 9.5-hectare plot adjacent to the existing plant to support new manufacturing buildings dedicated to next-generation DRAM and High Bandwidth Memory (HBM). This expansion is a cornerstone of the company’s strategy to meet surging AI demand and diversify its high-end memory production footprint.
The project is heavily backed by the Japanese government, which has committed up to 536 billion yen in subsidies to bolster domestic semiconductor sovereignty. Formal construction is slated to begin in May 2026, with the facility expected to reach operational status for volume shipments by 2028. This site will play a critical role in Micron’s competition with South Korean rivals, focusing on the specialized memory architectures required for the next wave of generative AI data centers.
