UAE’s Mubadala weighs $6.3 billion AI data center investment in Japan
Abu Dhabi's sovereign wealth fund is eyeing a 500-megawatt facility in Akita prefecture as part of a broader push to dominate global AI infrastructure
Mubadala Investment Co., one of Abu Dhabi’s largest sovereign wealth funds, is considering pouring up to Â¥1 trillion, roughly $6.3 billion, into building an AI data center in Japan’s Akita prefecture. The facility would pack 500 megawatts of capacity and is targeting an operational launch in the early 2030s.
What Mubadala is actually building
The project is being developed by US startup BitGrid in collaboration with Japanese IT firm S2. Mubadala’s involvement would come through MGX, the UAE’s dedicated AI investment vehicle that launched in March 2024 with ambitions to aggregate over $100 billion in assets spanning AI infrastructure, semiconductors, and core technologies.
MGX has been on something of a shopping spree. In July 2026, it completed the acquisition of Aligned Data Centers. It’s also reportedly in negotiations around a potential buyout of Singapore-based DayOne, which operates data center assets in Japan as well.
Japan has been actively courting foreign investment in data center infrastructure, leaning on two key advantages: abundant renewable energy resources and government policies that encourage decentralized computing facilities outside of major urban centers. Akita prefecture, located in northern Honshu, fits that profile.
The UAE’s bigger play
This investment fits neatly into the UAE’s multi-decade strategy to diversify its economy away from hydrocarbons. MGX’s ambition to manage over $100 billion in AI-related assets makes it one of the largest dedicated AI investment vehicles on the planet.
Japan has been actively repositioning itself as a global hub for AI infrastructure investment. Foreign direct investment into Japanese tech infrastructure has been climbing, and this potential Mubadala deal would represent one of the largest single commitments in the space.
What to watch from here
First, watch whether MGX formalizes this investment. A commitment of $6.3 billion would be one of the largest single data center investments by a sovereign fund.
Second, pay attention to the energy dynamics. A 500-megawatt facility is enormous, roughly equivalent to the power consumption of a mid-sized city.
