Japan and US Narrow First Picks for $550 Billion Investment Plan, With SoftBank-Linked Data Center Project in the Mix

Meta description: Japan and the United States are moving closer to selecting the first projects under a planned $550 billion Japan-led investment initiative into the U.S., with a major candidate tied to SoftBank and large-scale data center infrastructure.

What’s happening now

Japan and the United States have reportedly shortlisted a small group of early candidate projects for a major Japan-led investment framework that could total $550 billion in the U.S. economy. According to people familiar with the talks, the two governments have stepped up consultations to decide which projects should go first—because the “first picks” will set the tone for everything that follows: which sectors get priority, how money flows, how risk is shared, and how political leaders in both countries will explain the plan to their voters and businesses.

One of the most high-profile candidates said to be on the shortlist is a large-scale data center infrastructure project linked to SoftBank Group. While details remain limited, the project’s inclusion signals that the early phase may focus on the “digital backbone” of the modern economy—compute capacity, data storage, cloud infrastructure, and the power and networks that make these facilities run.

Why this investment plan matters

Big headline numbers like “$550 billion” can sound abstract, but this plan matters because it is not just about money—it’s about trade leverage, industrial strategy, and supply chain security.

In simple terms, Japan is aiming to channel a massive pool of capital into U.S.-bound projects in ways that benefit both countries. For the U.S., the payoff could include new infrastructure, jobs, technology capacity, and stronger domestic supply chains. For Japan, the plan is linked to a broader effort to reduce tariff pressure on Japanese exports to the United States and to preserve stable access to the American market.

And here’s the real strategic angle: the first set of projects will likely serve as a “template” for how later deals are evaluated—what counts as strategic, what counts as eligible, how financing is packaged, and how quickly projects can move from political agreement to real-world construction.

SoftBank’s data center link: why it stands out

Among the rumored early candidates, the SoftBank-linked data center infrastructure project stands out for a few reasons.

1) Data centers are now “national infrastructure”

Data centers used to be seen as private tech facilities. Today, they function more like essential infrastructure—similar to ports, power grids, and highways. They support everything from online services and banking to logistics, healthcare systems, and AI development. Governments care because whoever leads in compute capacity can gain advantages in innovation and competitiveness.

2) They connect directly to energy policy

Data centers require enormous and stable electricity supplies. That means any big data center push quickly becomes a conversation about energy generation, grid upgrades, and long-term power contracts. It also turns into a “speed test” for permitting and infrastructure planning, because delays can be expensive.

3) They can anchor wider ecosystems

Large data center clusters often attract related investments: fiber networks, equipment supply chains, advanced cooling systems, cybersecurity services, and—depending on the design—manufacturing and assembly work tied to hardware. In other words, one major project can pull in many supporting projects.

Reuters sources described the SoftBank-linked project as a large-scale infrastructure effort involving data center construction and listed it among the shortlisted items being discussed between both governments.

How the financing is expected to work

A core feature of this initiative is that it is expected to use multiple financial tools rather than a single “one-size-fits-all” approach. The planned package may include:

Equity investments

Equity means taking ownership stakes in projects or companies. This can align incentives and offer longer-term upside, but it also carries risk if projects underperform.

Loans

Loans can provide large amounts of capital with structured repayment terms. This approach is often used for infrastructure where cash flows (like usage fees or long-term contracts) can support repayment.

Loan guarantees

Guarantees reduce lender risk by backing repayment if a borrower defaults. This can make it easier and cheaper for projects to raise money at scale.

Reuters reported that Japan’s package is expected to include equity, loans, and loan guarantees involving state-backed institutions including the Japan Bank for International Cooperation (JBIC) and Nippon Export and Investment Insurance (NEXI).

Who is involved in the decision-making

Large bilateral initiatives don’t move forward on political will alone—they need bureaucratic coordination, technical screening, and financing structures that both sides can defend publicly.

Consultation committee talks

Reuters sources said Japan and the U.S. have held multiple consultation committee meetings since December involving major U.S. departments (including Commerce and Energy) and Japanese ministries (Foreign Affairs, Finance, and Industry), plus JBIC and NEXI.

An investment committee and final selection

Based on those consultations, an investment committee led by the U.S. Secretary of Commerce is expected to make recommendations to President Donald Trump, who would make the final selection, according to Reuters.

This structure matters because it indicates the projects won’t be chosen only by one ministry or agency. Instead, the selection process appears designed to balance trade interests, industrial policy goals, national security considerations, and financial feasibility.

Why timing is a big deal

Even if both countries agree in principle, timing can make or break the political value of an investment plan. According to Reuters, the two governments want to formalize the first project before Japan’s Prime Minister Sanae Takaichi visits the U.S. in the spring.

That target creates pressure to choose projects that are “ready enough”—meaning they can be announced with confidence, can clear early procedural steps, and can show measurable progress within a timeframe that political leaders consider meaningful.

The tariff backdrop and legal uncertainty in the US

This investment effort sits alongside a complicated tariff environment. Reuters noted that a U.S. Supreme Court ruling related to the legality of Trump’s global tariffs is expected soon, but that Tokyo has said it intends to move forward with the investment initiative regardless, describing it as a plan to build key supply chains and create mutual benefits.

In practical terms, this means Japan appears to be treating the investment plan as a long-term strategic project rather than a short-term “tariff trade.” Even if the legal situation shifts, the underlying industrial logic—securing supply chains, building shared capacity, and strengthening economic ties—still remains valuable.

What types of projects could be on the shortlist besides data centers

Reuters did not publicly detail the full list of shortlisted projects in the January 19 report, but the broader logic of the initiative points toward categories that governments commonly prioritize in strategic investment programs:

Energy and grid infrastructure

Especially projects that support reliable power delivery, grid modernization, and the energy needs of advanced manufacturing and data centers.

Advanced manufacturing and industrial capacity

Projects that expand production of critical components, improve resilience, and reduce bottlenecks—particularly in industries considered strategic.

Supply chain “chokepoint” upgrades

Investments in ports, logistics, storage, and industrial hubs can reduce delays and improve the security of cross-border supply networks.

Technology infrastructure

Beyond data centers, this could include high-capacity networks, cybersecurity, and systems that support digital trade and industrial automation.

Important note: The categories above are context, not a confirmed Reuters list. The only specific shortlist item Reuters sources highlighted in the January 19 report was the SoftBank-linked data center infrastructure project.

Why Japanese megabanks matter in this plan

Government-linked institutions like JBIC and NEXI can catalyze investment, but a $550 billion framework is so large that commercial finance often becomes essential. Reuters reported that talks have already begun with Japanese megabanks, which could participate alongside JBIC in financing.

If major banks join in, it could increase the plan’s scale and speed, while also imposing stricter financial discipline on which projects are viable. Banks tend to ask tough questions: How will the project earn revenue? What’s the timeline? What are the regulatory risks? Who bears cost overruns? That kind of scrutiny can make projects stronger—or can remove weaker proposals before they become political problems.

What SoftBank could gain—and what it risks

SoftBank is widely known for ambitious technology investments, and data center infrastructure fits into the broader trend of rising demand for computing capacity. A SoftBank-linked project being considered as an early candidate could offer several potential advantages:

Potential advantages

• Visibility and momentum: Being part of a flagship bilateral initiative can help accelerate partnerships, permitting support, and financing confidence.
• Scale benefits: Large infrastructure projects can reduce unit costs over time, especially when built in clusters.
• Strategic alignment: When projects match government priorities, they may be better positioned to navigate policy shifts.

Potential risks

• Political spotlight: Flagship projects can become targets for criticism if timelines slip or costs rise.
• Energy and community constraints: Data centers can face local pushback over electricity use, water use, land use, and environmental impact.
• Market cycles: If demand projections change, oversupply could pressure profitability—especially if many players build aggressively at once.

Because Reuters reported SoftBank did not immediately respond to a request for comment, many details remain uncertain.

How this fits into the broader Japan–US investment story

This January 19 development did not appear out of nowhere. Previous reporting has indicated sustained interest from both Japanese and U.S. companies in participating in the broader investment framework linked to the tariff deal. For example, Reuters earlier reported that around 20 companies had expressed interest in potential projects connected to Japan’s $550 billion commitment.

That context suggests the shortlist is not simply symbolic; it is likely the result of multiple parties pitching ideas, with governments trying to identify which ones are big enough to matter, practical enough to execute, and strategic enough to justify public support.

What to watch next

If you’re tracking this story, here are the most meaningful “next steps” to watch for in the coming weeks and months:

1) Official confirmation of the first project

The biggest turning point will be when both governments publicly name one or more initial projects and explain the financing structure.

2) More detail on project scope

For the SoftBank-linked data center plan, investors and communities will want specifics: location strategy, size, energy sourcing, construction timeline, and network partners.

3) The role of megabanks and private co-financing

If Japanese megabanks formally commit, it could signal that the program is shifting from political concept to bankable pipeline.

4) The impact of U.S. tariff-related legal developments

Even if Tokyo says it will proceed regardless, changes in U.S. tariff authority could reshape the political narrative around why this program exists and how it is sold domestically.
