Mubadala weighs ¥1 trillion bet on 500MW Akita data center

Abu Dhabi's Mubadala Investment Company is in talks to put up to ¥1 trillion, or $6.3 billion, into a 500-megawatt data center campus in Akita, Japan. The developers would be Bitgrit, a US Web3 and AI blockchain firm, and S2, an Akita server-management company. UAE ambassador to Japan, Shihab Alfaheem, described the possible investment in a Nikkei interview, according to Data Center Dynamics. If built, the campus would be a ¥2 trillion project and would not open until 2033.

Mubadala's ceiling is half the stated project cost. The reporting describes talks, not a signed deal. What exists on paper is the memorandum of understanding Bitgrit and S2 signed with the city of Akita in October, along with the formation of a special purpose company.

The two developers are an unusual pair. Bitgrit is a US Web3 and AI blockchain firm that trains models on private data for client organizations. S2 is an Akita server-management company that in 2021 launched Japan's first professional esports team made up of elderly players, the Matagi Snipers.

Their first step is far smaller: a 1.5MW facility in Akita expected at the end of 2027. That pilot is the project's first real test. The jump from 1.5MW to 500MW is a different category of infrastructure. The coverage does not say how the pilot will be financed or who would buy the campus's power once it exists.

Those unknowns will decide whether Akita becomes a revenue asset or an expensive vacant site. Few private funds would sit still for a seven-year construction horizon without a contracted customer and a construction lender in place. Sovereign balance sheets are built to tolerate that wait. Mubadala's reported interest suggests a state investor is willing to hold those open questions for the better part of a decade.

The Akita talks arrive the same week AWS raised its Louisiana data center commitment to $18 billion. The company added a $6 billion Shreveport campus and took on its own water and grid costs, as Private Infrastructure Daily has reported. Mubadala would play a different part: equity into a developer-led campus, with risk spread across seven years.

For now Akita has a memorandum of understanding and a small pilot on the schedule. The trillion-yen commitment will have to wait for what that pilot proves.
