Mubadala, the UAE sovereign wealth fund, committed up to $6.3 billion to build AI data centers in Japan.

The United Arab Emirates' sovereign wealth fund Mubadala Investment Company is considering investing up to ¥1 trillion ($6.3 billion) in an AI-focused data center project in northern Japan. The proposed facility, located in Akita Prefecture, would have a capacity of 500 megawatts and potentially become Japan's largest data center upon completion.

Mubadala is expected to lead the financing, though the project's scale may require additional domestic and international investors. Total investment could reach ¥2 trillion ($12.6 billion), reflecting the ambition of the development.

The investment reflects Japan's broader acceleration in AI and digital infrastructure spending. Earlier this year, NTT Data announced plans to invest at least ¥1.5 trillion ($9.6 billion) through 2033 to expand its domestic data center footprint, with capacity increases of approximately 750 megawatts, bringing total capacity to 1 gigawatt.

For Mubadala, the Akita development would mark its first direct investment in a Japanese data center. The Abu Dhabi fund has constructed a global digital infrastructure portfolio through investments in operators including Cologix, Princeton Digital Group, GlobalConnect, Aligned Data Centers, and Yondr Group.
