Apollo Backs a $15 Billion Artificial-Intelligence Build in Japan as Credit Becomes the Sector's Constraint

The Chiba prefecture project will draw up to 400 megawatts from a Jera power station, while SoftBank's shareholders and the market for Nidec's shares test how much borrowed money the buildout can carry.

Apollo Global Management will act as strategic investment and financing partner for a project of more than $15 billion to build artificial-intelligence capacity in Japan, The Japan Times reported. The developer is the United Kingdom firm RHAELM Holdings, working with Jera, Japan's largest power generator, and Dell Technologies, on a site in Chiba prefecture. Capital will go into land, electricity infrastructure, construction and computing hardware. Bloomberg reported that operations are scheduled to begin around 2028 and that the complex will draw as much as 400 megawatts, supplied with help from a nearby Jera thermal plant.

The financing structure is the point. Apollo is a private credit manager, and it already arranges financing for artificial-intelligence projects involving Nvidia, Broadcom and Anthropic. Power, land and buildings are being funded with borrowed money against revenue that will not arrive until the end of the decade, at a moment when the 30-year United States Treasury yield is near 5.7%.

Japanese investors are weighing the same question through SoftBank Group. The Japan Times reported that equity holders are setting aside the credit risk in Masayoshi Son's structures because his exposure spans robotics, data centres and energy, and that this breadth reassures some of them about eventual returns. Elsewhere in the supply chain, Nidec, the motor manufacturer, set out a recovery plan under new leadership that includes selling business units and investing in artificial-intelligence-related products, as it tries to avoid delisting or a hostile takeover.

The sequence across the three stories is coherent. Capital is abundant for anyone building computing capacity, scarce for incumbent manufacturers that have to fund a turnaround from cash flow, and increasingly dependent on credit markets rather than retained earnings.

What this means

The mechanism is the cost of long-dated credit against revenue that begins in 2028. Private credit managers such as Apollo earn fees for originating these loans and distribute the exposure to insurers and pension funds, so the holders of the risk are the buyers of that debt, alongside the utilities and contractors whose order books assume the projects are built. Japan is the preferred venue because it has spare thermal generation capacity and a large manufacturing base, which also ties Jera's revenue to artificial-intelligence demand holding up. The likelier outcome over the next few quarters is more announcements of this type, financed privately rather than through public bond markets, with the first signs of strain appearing in the pricing of data-centre debt rather than in cancelled projects. A sharp widening in spreads on data-centre and power-project credit, or a developer failing to reach financial close, would show the constraint has moved from ambition to funding.

What to watch

Pricing and investor demand on the next large private-credit financing for a data centre, the clearest signal of whether lenders still accept 2028 revenue assumptions.
Jera's disclosures on power contracted to data centres, since committing thermal capacity to computing competes with industrial and household electricity supply.
Whether Nidec's asset sales attract buyers at the prices it needs, a test of whether capital is reaching the industrial supply chain or only the computing layer.
