The mining shed that grew up to run the grid

In 1910, in a small shed in Ibaraki Prefecture, a young electrical engineer named Namihei Odaira built a 5-horsepower induction motor - the first of its kind made in Japan - to run the machinery of a copper mine. It was a repair operation with big ideas. More than a century later, the descendant of that shed employs roughly 288,000 people, books around 9.78 trillion yen (about $69 billion) a year, and keeps the electricity flowing and the trains running across some 50 countries. Most people have never bought a single thing from it.

That is the peculiar shape of Hitachi. It is one of the largest technology companies on earth, and one of the least understood outside boardrooms and control rooms. The consumer knows it, vaguely, from an air conditioner or a power drill. The utility engineer knows it as the company that supplies the transformers and high-voltage links holding a national grid together. The transit authority knows it as the firm signaling its trains. Increasingly, the CIO knows it as the company writing their software. Hitachi calls the thread connecting all of this its "Social Innovation Business." The plainer version: it sells the machines that make a country work, and then it sells the software that makes the machines smarter.

01 / WHAT IT DOESAn infrastructure company wearing a software company's clothes

Hitachi today runs on three big pillars. Digital Systems & Services covers IT, consulting, data infrastructure, and the digital-engineering work done by GlobalLogic. Green Energy & Mobility houses Hitachi Energy - the grid-technology business built from the former ABB Power Grids - and Hitachi Rail. Connective Industries spans industrial machinery, building systems, healthcare equipment, and water. Sitting across all of them is Lumada, the digital platform Hitachi launched in 2016 to turn sensor data from physical operations into predictions, dashboards, and decisions.

The reason this structure matters is margin. Selling a transformer is a good business, but it is a one-time, capital-heavy sale. Selling the software and services that monitor that transformer for the next 20 years - predicting failures, scheduling maintenance, optimizing load - is a recurring business with far better economics. Hitachi's entire modern strategy is to sit on top of hard, physical assets that competitors cannot easily copy, and charge for the intelligence that runs them.

Hitachi doesn't sell you the grid. It sells the software and services that keep the grid from failing - and that layer is much harder to rip out. The Lumada thesis, in one line

02 / THE PLATFORMLumada, the ¥4 trillion idea that started as a slogan

When Lumada launched, critics called it "all concept, no substance" - a marketing wrapper around a grab-bag of projects. Nine years later it is reportedly a business worth on the order of ¥4 trillion, and the wrapper turned out to be the point. Lumada gave a sprawling conglomerate a common language for analytics, IoT, digital twins, and AI, and a way to package a factory-floor deployment in one division as a repeatable product for another.

The current chapter is "Lumada 3.0," and its keyword is Physical AI. The industry, Hitachi argues, is moving from generative AI (which drafts the email) to agentic AI (which runs the office workflow on its own) to Physical AI (which reaches out into the frontline - the train, the transformer, the robot arm - and acts). In September 2025 the company stood up a Lumada 3.0 Strategy Promotion Office. In January 2026 it announced a full reorganization to match, including a new Digital Engineering & AI Solutions unit built around GlobalLogic and a new AI & Software Services unit. When a 288,000-person company rewires its org chart around an idea, the idea has stopped being a slogan.

03 / CUSTOMERSThe people who call Hitachi when the lights flicker

Hitachi is almost entirely a business-to-business and business-to-government company. Its customers are utilities and grid operators wiring in wind and solar; national railways and city metros; manufacturers automating plants; hospitals running imaging systems; banks, telecoms, and public agencies modernizing their IT. These are not impulse buys. A high-voltage direct-current link or a rail-signaling contract is a multi-year commitment, which is why Hitachi Energy's order backlog has swelled to roughly $63.6 billion - a queue of work the energy transition simply cannot proceed without.

Hitachi Energy's backlog is about $63.6 billion. That is not a valuation. It is the length of the line for the equipment the world's clean-energy plans depend on. On the grid crunch

04 / THE PROBLEM IT SOLVESOld machines, new demands

The world is asking its physical infrastructure to do things it was never designed for. Grids built for steady, one-directional power from a few big plants now have to juggle millions of intermittent solar panels and wind farms - and, soon, the enormous demand of AI data centers. Railways are asked to run more trains, more safely, on the same tracks. Factories want to predict a breakdown before it happens rather than react after. Each of these is a problem of squeezing more reliability and intelligence out of hardware that already exists.

That is the gap Hitachi aims for: it makes the physical equipment and the software layer that optimizes it. HVDC links and grid automation to move renewable power over long distances. Digital signaling to pack more trains onto a line without adding track. Predictive-maintenance models that read a machine's vibrations and flag the failing part. The pitch is not "buy our gadget." It is "we will keep your critical system running, and make it smarter every year."

05 / HOW IT'S DIFFERENTOwning both the steel and the software

Hitachi's rivals tend to sit on one side of a line. Pure IT-services firms like Accenture write excellent software but do not manufacture transformers. Pure equipment makers know their hardware cold but often lack a deep software-engineering bench. Hitachi's bet - the reason it paid roughly $9.6 billion for GlobalLogic in 2021 and folded in Hitachi Energy from ABB in 2020 - is that owning both the operational technology (the steel) and the information technology (the software) is a durable advantage. When the same company builds the grid asset and the model that predicts its failure, the two are designed to fit.

Its closest peers in this "both sides" game are Siemens and GE, each pursuing a similar fusion of industrial hardware and digital services. Schneider Electric, ABB, Mitsubishi Electric, and Toshiba compete across energy and industrial automation; Alstom competes in rail. But few match Hitachi's particular spread - from data-storage hardware through grid equipment to bullet trains, all pulled under one platform.

06 / PRODUCTS & SERVICESA portfolio you can walk through a city with

Take a walk through a modern city and you can trace Hitachi's catalog. The power feeding the buildings may cross a Hitachi Energy HVDC link and pass through its transformers and grid-automation software. The metro you ride may run on Hitachi Rail trains and its digital signaling - a business massively expanded by the roughly €1.66 billion acquisition of Thales' Ground Transportation Systems in 2024. The enterprise apps on your phone may have been engineered by GlobalLogic. Behind the scenes, Hitachi Vantara stores and manages the data; Hitachi Astemo supplies braking and powertrain systems to carmakers; and Lumada, plus the newer HMAX AI services, ties the intelligence together.

07 / BUSINESS MODELHardware up front, intelligence forever

The revenue engine has several cylinders: equipment sales, long-cycle infrastructure projects with multi-year backlogs, IT and consulting services, maintenance and managed services, and software subscriptions through Lumada. The strategic tilt is unmistakable - away from selling a box once and toward a relationship that recurs. A rail contract increasingly means signaling and systems, not just rolling stock. A grid order increasingly comes with software and service attached. In fiscal 2024 that mix pushed adjusted EBITA to a record of roughly ¥1,141.8 billion, with net income near ¥615.7 billion.

08 / EXPERTISE & PARTNERS115 years of engineering, plus a few new friends

Hitachi's deepest asset is time. It has been designing motors, grids, and control systems since before most of its competitors existed, and that operational-technology knowledge is genuinely hard to buy. To bolt modern AI onto it, the company has leaned on partners: it is building a distributed AI cloud with NVIDIA to run "Physical AI" for factories, rail, and energy; it delivers generative-AI copilots on Microsoft Azure OpenAI; and it works with AWS and Google Cloud. In 2025 it also agreed to acquire the German data-and-AI firm synvert to feed its HMAX business. Steering the brand in its fastest-growing region is CMO Arya Barirani, who helped build GlobalLogic's "digital engineering" category before joining Hitachi.

The evolution from generative AI to agentic AI to Physical AI is reshaping the frontline. That shift is where Hitachi is placing its next bet. On Lumada 3.0

10 / WHERE IT FITSThe load-bearing wall of the modern economy

There is a version of tech success built on being famous - a logo everyone recognizes, a product everyone touches. Hitachi took the other route: becoming load-bearing. It is the kind of company that, if it stopped working tomorrow, would be felt in dimmed grids and delayed trains long before anyone thought to blame it by name. As the world simultaneously electrifies, digitizes, and races to deploy AI in the physical world, the company that makes both the equipment and the intelligence to run it has found itself standing in a useful spot. The mining shed of 1910 has, in its quiet way, become part of the wiring.
