Mubadala Investment, the Abu Dhabi-based sovereign wealth fund, is in negotiations to invest up to ¥1 trillion (roughly $6.5 to $7 billion) in a proposed AI data center in Akita Prefecture, Japan. The total investment across all participants could reach ¥2 trillion, according to Bloomberg.

If built, the facility would have a capacity of approximately 500 MW, making it Japan’s largest data center.

Why Japan, and why now

Japan has been on a quiet but aggressive campaign to become a global hub for AI compute infrastructure. In June 2026, the government released a strategic plan projecting ¥32.7 trillion in combined public and private investment by fiscal year 2035, all aimed at expanding cloud and data center capacity across the country.

The government is backing the push with tax incentives and active courtship of foreign capital. Mubadala’s potential involvement represents exactly the kind of deal Tokyo has been chasing.

A Japanese corporate consortium is expected to lead construction and operations, with Mubadala and other international and domestic investors providing the capital.

The discussions are still at an early stage, and Mubadala has declined to comment publicly.

The AI infrastructure arms race and its crypto implications

The intersection of AI and crypto has been one of the most active investment themes of the past two years. Tokens tied to decentralized compute, like those powering GPU rental marketplaces and distributed training networks, have seen their valuations swing wildly based on exactly these kinds of infrastructure announcements. A ¥2 trillion centralized data center project represents both competition and validation for decentralized alternatives.

Sovereign wealth funds moving aggressively into AI infrastructure also signals something about where traditional finance sees the next decade of returns. Mubadala manages hundreds of billions in assets with a mandate to diversify the UAE’s economy beyond oil.

What investors should actually watch

Japan’s broader ¥32.7 trillion infrastructure plan by fiscal year 2035 is the more important number here. The Akita project is a single data center. The national strategy represents a fundamental reorientation of Japan’s technology economy, and it’s happening at the same time the country has been liberalizing its approach to digital assets and Web3 businesses.

The risk, as always with early-stage megaprojects, is execution. A ¥2 trillion data center in a prefecture with limited existing tech infrastructure faces construction timelines, permitting challenges, and the basic physics of power generation. Mubadala hasn’t even confirmed its involvement publicly yet.
