Mubadala Investment Co., Abu Dhabi's sovereign wealth fund, is weighing a ¥1 trillion commitment to build a massive AI data center in Japan's Akita prefecture. The 500-megawatt facility would come online in the early 2030s, marking one of the largest single infrastructure plays by a Middle Eastern fund in the region's tech boom.
The project is being developed with US startup BitGrid and Japanese IT firm S2. Mubadala would fund it through MGX, the UAE's dedicated AI investment vehicle that launched in March 2024 with a target to manage over $100 billion across AI infrastructure, semiconductors, and related tech. MGX has already been aggressive on dealmaking. It closed the acquisition of Aligned Data Centers in July 2026 and is reportedly negotiating to buy Singapore-based DayOne, which operates data center assets across Japan.
Why Japan, and why now
Japan is actively hunting foreign capital for data center infrastructure. The country sits on abundant renewable energy and has government backing for decentralized computing facilities outside Tokyo and Osaka. Akita, in northern Honshu, ticks both boxes. A 500-megawatt facility would consume power equivalent to a mid-sized city, so location and energy supply matter enormously.
The broader context here is Japan's repositioning itself as a global AI infrastructure hub. Foreign direct investment into Japanese tech infrastructure has been climbing steadily, and a $6.3 billion Mubadala bet would rank among the largest commitments the country has landed. For the UAE, this fits a decades-long push to diversify away from oil. MGX's ambition to control over $100 billion in AI assets makes it one of the largest dedicated AI funds globally.
Two things to monitor. First, whether MGX actually formalizes this investment, which would be a landmark sovereign fund move. Second, the energy dynamics. A facility of this scale requires stable, massive power supply, and Japan's renewable capacity will be central to whether the project pencils out long-term.
