Japan accelerates semiconductor and data center investments amid AI boom
Japan is experiencing a significant surge in high-tech infrastructure investment, driven by the global artificial intelligence boom and the need for semiconductor sovereignty. The semiconductor fab construction market is expanding as the nation targets advanced 2nm manufacturing, with Rapidus leading efforts to begin mass production by 2027.
Parallel to semiconductor growth, the data center market in Japan is projected to exceed 5 trillion yen by 2028. Major real estate developers are scaling up operations to meet AI-driven demand; Daiwa House Industry Co. plans to build 14 data centers in Chiba Prefecture, while Mitsui Fudosan Co. aims to invest over 600 billion yen in related projects by fiscal 2035. This shift is also driving demand for specialized services, including liquid cooling technologies to manage the intense thermal loads of AI accelerators.
To support these advanced industries, Japan is also addressing critical supply chain vulnerabilities regarding rare earth elements. While the nation remains 100% dependent on China for heavy rare earth imports, strategic efforts are underway to diversify sources through partnerships in Australia and other regions to secure materials essential for electric vehicles, robotics, and semiconductor production.
