Micron Memory Japan opens new office in Higashihiroshima to accelerate semiconductor innovation
Wednesday, March 11, 2026 at 09:28 AM
Micron Memory Japan, the Japanese subsidiary of U.S. semiconductor giant Micron Technology, has opened a new office in the center of Higashihiroshima City. This facility is intended to accelerate innovation and strengthen the company's local operations near its existing DRAM manufacturing presence in the Hiroshima area.
Context
U.S. memory leader Micron Technology is deepening its presence in Japan with the opening of a new office in central Higashihiroshima. This move serves as a precursor to a massive $9.6 billion (1.5 trillion yen) investment to build a next-generation high-bandwidth memory (HBM) production facility. Construction of the new fab is slated to begin in May 2026, with mass production expected by 2028 to meet the surging global demand for generative AI and data center hardware.
The expansion is heavily supported by the Japanese government, which has committed up to 500 billion yen in subsidies to bolster domestic semiconductor sovereignty. By integrating advanced EUV lithography at the Hiroshima site, Micron aims to bridge the market share gap with South Korean rival SK Hynix. This strategic pivot also diversifies Micron’s HBM supply chain away from Taiwan, mitigating regional geopolitical risks while securing a critical role in the global AI chip ecosystem.
