To go broader and identify your own highest conviction ideas in the space, head straight to the Nuclear Energy Stocks screener.

Hitachi (TSE:6501)

Hitachi is a diversified technology and industrial group that spans digital systems, energy grids, mobility and factory automation, all of which tie neatly into long term electrification and nuclear infrastructure themes. It generates about ¥3.5t in Energy revenue, ¥3.4t from Connective Industries and ¥3.0t from Digital Systems & Services, with Mobility adding around ¥1.4t, which shows how much of the business is tied to power, infrastructure and data. With a market cap of roughly ¥25.9t, Hitachi sits at the scale where its AI partnerships with OpenAI, Google, Intel and Anthropic, recent storage and grid wins, and forecast mid teens earnings growth could matter. However, a high P/E, heavy capital spending and exposure to project cost inflation mean investors need to weigh both the potential upside and the execution risk.

Hitachi’s AI partnerships and nuclear exposure could be masking a bigger story in its earnings trajectory. Get the full context in the analyst forecasts for Hitachi to see what the current expectations might be missing.

ITOCHU (TSE:8001)

ITOCHU is a global trading and investment group that connects everything from textiles and food to metals, machinery, energy and digital services. It is heavily weighted to consumer and resources, with Food generating ¥5,140.1b in revenue, Energy & Chemicals ¥3,223.0b, Machinery ¥1,526.5b and General Products & Realty ¥1,567.4b, alongside meaningful contributions from ICT & Financial Business, Metals & Minerals, Textile and The 8th segments. With a market cap around ¥14,437.2b, ITOCHU sits among Japan’s largest trading houses.

ITOCHU is worth a closer look if you are interested in how a traditional trading house is trying to pivot toward more stable, higher margin areas linked to consumer demand, green energy and recycling. The Casablanca waste to energy project and broader decarbonization and circular economy push sit alongside capital allocation moves like the ¥300,000m buyback program, which together point to a tighter focus on long term earnings quality and shareholder returns. Set against this are real pressure points, including reliance on resource linked segments, use of one off gains and a high debt load that can amplify any downturn. The balance between these strengths and risks is where the opportunity, or the downside, may lie for patient investors.

ITOCHU’s push into decarbonization, recycling and consumer focused businesses could be reshaping its earnings quality, while that high debt load quietly raises the stakes. Get the full story in the 2 key rewards and 1 important warning sign

Mitsubishi Heavy Industries (TSE:7011)

Mitsubishi Heavy Industries is a global industrial group that supplies energy systems, infrastructure equipment, logistics and thermal systems, and aircraft, defense and space hardware. The business is anchored by Energy Systems, which generated about ¥2,175.8b, followed by Aircraft, Defense & Space at roughly ¥1,419.4b and Plants & Infrastructure Systems at around ¥873.0b, with smaller contributions from other segments and internal adjustments. With a market cap of about ¥14.3t, Mitsubishi Heavy Industries sits among Japan’s large industrial and energy transition players.

Investors looking at nuclear energy stocks may want to note how Mitsubishi Heavy Industries is linking its next generation energy portfolio, including nuclear and carbon capture, with a record order backlog in clean power, infrastructure and defense. Earnings have been growing and margins are improving, helped by higher value projects and cost control, yet the stock already trades on a rich P/E and relies on external borrowing, which raises financial risk. When you add in expansion in the U.S., partnerships on AI data center power and cooling, and rising defense exposure, you get a mix of growth, funding and governance questions that may warrant a closer look before deciding how it fits in a nuclear focused portfolio.

Accelerating orders and cleaner energy projects at Mitsubishi Heavy Industries may be masking the real story. Use the analyst forecasts for Mitsubishi Heavy Industries to see how earnings expectations line up with that rich P/E and what could change next.
