Bond yields in Japan and other major economies recently reached levels not seen in decades, which has put borrowing costs in the spotlight and sharpened interest in power sources that do not rely on imported fuel. Japanese nuclear energy stocks sit at the crossroads of energy security and cleaner electricity. This article walks through three nuclear focused companies from our screener that investors may want on their radar now.

The three nuclear focused stocks highlighted below are only a small sample, and the wider screen surfaced 34 more companies with similarly detailed stories that are not covered here.

If you want to quickly identify which nuclear plays best fit your own thesis, head straight into the Nuclear Energy Stocks screener to filter, analyze, and focus on your highest conviction opportunities.

Marubeni (TSE:8002)

Overview: Marubeni is a diversified Japanese trading and infrastructure group that links global supply chains and operates power, nuclear and industrial projects.

Operations: Marubeni generates most of its revenue from Food & Agri Business at ¥3,848.8b, followed by Energy & Chemicals at ¥1,522.0b and Metals & Mineral Resources at ¥1,020.3b.

Market Cap: ¥7,997.2b

For nuclear focused investors, Marubeni offers exposure through development, trading and engineering, procurement and construction services for nuclear facilities within a broad power and infrastructure portfolio. Earnings growth forecasts and a P/E close to the wider Japanese market frame that specialist exposure as a more measured entry point, depending on how one unseen pressure plays out.

That unseen pressure could be crucial, so review the 4 key rewards and 2 important warning signs to see how Marubeni’s nuclear exposure and valuation could be pulling in opposite directions.

ITOCHU (TSE:8001)

Overview: ITOCHU is a broad trading group that runs nuclear-fuel trading and power generation infrastructure alongside consumer, industrial and resource businesses.

Operations: ITOCHU earns most revenue from Food at ¥5.1t and Energy & Chemicals at ¥3.2t, with sizeable Machinery and Metals & Minerals contributions.

Market Cap: ¥15.3t

ITOCHU provides exposure to nuclear power not through a single reactor build, but through the flow of fuel and infrastructure that keeps plants running.

Continued investment in sustainability, such as decarbonization and circular economy initiatives, is likely to generate new revenue streams as global demand for green energy and sustainable products increases.

The key question is how this shift in where profits come from ultimately affects earnings stability and pricing power.

That profit mix is already shifting, so read the full narrative for ITOCHU to see how ITOCHU’s nuclear role, fuel flows and sustainability push could be decoupling future earnings drivers.

Mitsubishi Heavy Industries (TSE:7011)

Overview: Mitsubishi Heavy Industries develops and services nuclear power systems alongside a broad mix of energy, infrastructure, industrial and defense equipment.

Operations: Mitsubishi Heavy Industries generates most revenue from Energy Systems at ¥2.2t, Aircraft, Defense & Space at ¥1.4t, and Plants & Infrastructure Systems at ¥0.9t.

Market Cap: ¥13.1t

For investors focused on nuclear energy, Mitsubishi Heavy Industries brings direct exposure to reactor design and fuel-cycle services inside a much wider engineering group. This matters if you want nuclear exposure without tying everything to one single technology line.

"MHI's early-mover advantage and leadership in next-generation decarbonization technologies, especially in hydrogen, ammonia, and carbon capture, position the company to capitalize disproportionately on global climate policy acceleration, unlocking new high-margin revenue streams and outpacing peer growth as governments and industry scale investments."

What really moves the needle for Mitsubishi Heavy Industries is how one tightly watched shift in project mix filters through long term margins.

That pivot in project mix is where expectations start to accelerate. Read the full narrative for Mitsubishi Heavy Industries to see how Mitsubishi Heavy Industries turns that shift into potential upside.
