Japanese Nuclear Energy Stocks Tied To AI Infrastructure Growth

Simply Wall St·08/14/2026 02:23:22
Listen to the news

Central banks are keeping interest rates restrictive as inflation sits above target in many regions. That keeps borrowing costs elevated and puts steady, large scale energy projects in the spotlight for investors seeking clearer visibility on demand. Nuclear energy stocks sit at the center of that story, tied to long term power contracts and infrastructure. This article highlights three nuclear energy stocks from our screener that may warrant a closer look.

The stocks covered below are just a sample, and the full screen surfaced 32 more nuclear energy companies with equally compelling stories that are not included here. If you want to identify your own highest conviction ideas, head straight into the Nuclear Energy Stocks screener to filter and analyze the full set of opportunities.

Hitachi (TSE:6501)

Overview: Hitachi is a broad based industrial and technology group that runs everything from nuclear and renewable energy systems to digital IT services, rail and mobility solutions, and factory automation, serving governments and large enterprises worldwide.

Operations: Hitachi generates most of its revenue from Connective Industries at about ¥3.35t, Digital Systems & Services at about ¥3.01t, and Energy at about ¥3.46t, with additional contribution from Mobility at about ¥1.38t and smaller segments.

Market Cap: ¥25.57t

Hitachi provides exposure to several powerful themes in one stock, from nuclear and grid infrastructure to AI driven digital services. The group reports earnings that have been growing faster than the wider Japanese market, and Lumada and HMAX software, data center power projects, and high value rail and semiconductor equipment are pushing the business mix toward more recurring and service based income. At the same time, investors need to weigh a rich P/E, heavy use of external borrowing, and execution risk on very large grid and data center projects. Recent AI partnerships with OpenAI, Google Cloud and Intel, and ongoing share buybacks, add further angles that are worth understanding in more detail.

Hitachi’s mix of nuclear, grid and AI driven services can look like a growth engine that the headline P/E only partly explains. Get the full story in the DCF valuation analysis for Hitachi to see what the market might be missing.

ITOCHU (TSE:8001)

Overview: ITOCHU is a global trading and investment group that links resource, industrial and consumer supply chains, from textiles and food to machinery, metals, energy, real estate and financial services.

Operations: ITOCHU generates most of its revenue from Food at about ¥5.1t and Energy & Chemicals at about ¥3.2t, followed by General Products & Realty at about ¥1.6t, Machinery at about ¥1.5t, ICT & Financial Business at about ¥1.2t, Metals & Minerals at about ¥1.3t, and Textile at about ¥0.7t.

Market Cap: ¥14.53t

ITOCHU gives you exposure to everything from everyday consumer spending to battery materials and waste to energy projects, which can help smooth out some of the usual commodity cycle swings. The company has been increasing its focus on higher margin consumer and sustainability focused businesses, supported by projects such as the Casablanca waste to energy plant and battery materials partnerships. It is also returning cash through a sizeable share buyback and a 2.12% dividend. At the same time, earnings still rely on resource segments, the company carries a high debt load and has experienced recent profit pressure. This raises questions about how durable future growth and dividends will be. That combination of strengths and areas of uncertainty is one reason many investors follow ITOCHU closely.

ITOCHU’s push into higher margin consumer and sustainability projects could be masking a very different earnings profile beneath its resource exposure. Review the full 2 key rewards and 1 important warning sign before the next phase of its story becomes clearer.

Mitsubishi Heavy Industries (TSE:7011)

Overview: Mitsubishi Heavy Industries is a diversified engineering group that builds and services everything from nuclear and thermal power plants to ships, aircraft engines, defense systems, air conditioning and carbon capture equipment for customers around the world.

Operations: Mitsubishi Heavy Industries generates most of its revenue from Energy Systems at about ¥2.18b, Aircraft, Defense & Space at about ¥1.42b, and Plants & Infrastructure Systems at about ¥0.87b, with smaller contributions from Others and internal segment adjustments.

Market Cap: ¥14.30t

Mitsubishi Heavy Industries gives investors exposure to clean energy build out, grid scale carbon capture and higher defense and aerospace spending, supported by a record order backlog and net profit margins at 8%. Earnings grew 62.7% over the past year. The current P/E sits well above the Machinery sector average, which makes careful valuation work important. The stock also carries execution risk from large, complex projects, exposure to currency swings and higher working capital needs as inventories rise. In addition, talks with Nvidia on AI data center cooling and energy systems and a push into lower cost carbon capture projects indicate that there are multiple strategic initiatives underway at Mitsubishi Heavy Industries.

Mitsubishi Heavy Industries has earnings growth, a record order backlog and a premium P/E that many investors may not have fully connected. Get the story behind those numbers in the analyst forecasts for Mitsubishi Heavy Industries before one key assumption breaks the thesis wide open.
