Hitachi, Ricoh, and the modular turn in battery manufacturing
On 2 June 2026, Nikkei Asia reported that Hitachi and Ricoh are joining forces to market low-cost, modular manufacturing systems for EV battery producers. Both firms have long histories as equipment makers rather than cell manufacturers themselves, and the arrangement positions them to supply a broad roster of clients — from established cell giants to newer entrants. Read narrowly, the deal is a service-line partnership. Read more carefully, it is the next chapter in a Japanese industrial design tradition being applied to the most contested manufacturing segment in the global auto industry.
The partnership, as it can be read from the wire summary, is less about headline capacity than about architecture. By offering a modular, cost-engineered plant template, Hitachi and Ricoh are betting that battery-making — long treated as a fortress industry dominated by a handful of cell giants — can be unbundled, demystified, and re-bundled into something closer to a turnkey kit. For the arts and material culture reader, the interest is less in the gigawatt hours than in what the partnership reveals about how Japanese industrial craft absorbs a new material problem.
A service-line partnership, deliberately narrow
The framing matters. Hitachi and Ricoh are not entering the cell business; they are selling the tools to enter it. That distinction has been a feature of Japanese industrial strategy for decades — the country has historically preferred to control the production equipment, the precision components, and the upstream inputs, then license or supply those to the eventual brand owners. The Nikkei summary describes a "cost-effective manufacturing model" aimed at battery makers who themselves face intense cost pressure as electric vehicles move from premium segments to mass-market price points.
A modular plant is, in plain terms, a battery factory in pieces. It can be shipped in standard containers, erected on a smaller footprint, scaled up by adding modules, and reconfigured as cell chemistry changes. The pitch to a battery maker is the same pitch that any contract manufacturer might make: lower upfront capex, faster time to first production, less risk that a single bet on a process technology locks the operator into a stranded asset. The pitch to a Hitachi or Ricoh executive is different — it is a recurring revenue stream tied to a structural shift, not a one-off sale.
Lineage: from switchgear to shutter to cell
Hitachi was founded in 1910 by electrical engineer Namihei Odaira in the mining town of Hitachi, in what is now Ibaraki Prefecture. Its first products were induction motors designed to drive the copper mines of the region; the company grew into a diversified industrial conglomerate whose reach extends from power-generation turbines to high-speed rail to information systems. Ricoh, by contrast, was founded in 1936 as Riken Kankōshi, a maker of sensitized photographic paper, before pivoting into optical-mechanical components — most notably the leaf shutter — and later into copiers, printers, and document-management software. The two companies, on the surface, occupy adjacent but distinct categories of Japanese manufacturing.
What they share, in the language of design history, is a pedigree in precision. Hitachi's equipment business was built on the assumption that the difference between a working power plant and a failed one was a question of tolerances measured in thousandths of a millimetre. Ricoh's camera-shutter work, similarly, treated mechanical reliability as a craft problem before it was a manufacturing one. The idea that a battery cell is, in part, a piece of precision hardware — and that the line that builds it can be designed with the same discipline — is the assumption that joins the two firms' cultures. Neither is a stranger to the cell ecosystem. Hitachi has shipped production equipment for advanced battery lines; Ricoh's industrial business includes process-control and surface-treatment systems used in electronics manufacturing.
The modular turn, in context
Modularity is not a new word in the battery industry. Chinese cell makers, led by CATL, have spent the last decade pushing the unit economics of lithium-iron-phosphate cells down to price points that would have seemed implausible a generation ago. South Korean competitors — LG Energy Solution, Samsung SDI, SK On — have matched them on energy density with nickel-rich chemistries. The Western response, in North America and Europe, has been a mix of subsidy-driven gigafactory construction and, more recently, slower deliberation about whether the gigafactory model itself is fit for purpose. Tesla, Panasonic, and a handful of joint ventures are the most visible large-scale cell producers outside Asia.
The Hitachi–Ricoh proposition sits in a different register. It is not a cell. It is the factory that makes the cell, sold as a kit. That posture is well-suited to a market in which cell chemistry is still in motion — sodium-ion, solid-state, lithium-iron-manganese-phosphate, and various hybrids are all under serious industrial development — and in which the country-by-country political question of where to build a multi-billion-dollar gigafactory is becoming harder, not easier, to answer. A modular offering accepts that the answer will be arrived at incrementally, plant by plant, and that the equipment vendor is the one party that can serve all of those answers without having to pick one.
The Chinese counter-position deserves to be heard on its own terms. China's lead in battery production is the result of a coordinated industrial policy, patient capital, and an unmatched supplier base. No modular kit, however cleverly engineered, can match the unit cost of a Chinese cell today; nor is the equipment market, on its own, large enough to close that gap. What it can do is offer a path for jurisdictions and joint ventures that do not want to import a complete Chinese supply chain, and that do want to keep the option of switching chemistries open.
Stakes and what to watch
Three things are worth tracking in the months ahead. First, the size and terms of the formal agreement: Nikkei's early framing is deliberately broad, and the price of a modular plant line, the financing arrangements, and the customer pipeline will determine whether this is a niche service or a category-defining product. Second, the customer list. If a major cell maker — a CATL, an LG Energy Solution, a Panasonic — signs on, the modular pitch has been validated at scale. If the early customers are second-tier or specialty players, the proposition will be read as a niche tool. Third, the chemistry question. Modular is easier to sell when the customer is still deciding what to make; it is harder to justify once the industry has consolidated around two or three dominant cell formats.
For the arts reader, the deeper question is whether the Japanese industrial-craft tradition — with its long memory of tolerances, of process control, of equipment that is engineered to be operated rather than merely sold — can find a renewed commercial register in a global industry that has, for the past decade, defined itself around scale. The answer, on the evidence so far, is that Hitachi and Ricoh are not trying to out-scale the cell giants. They are trying to be indispensable to whichever scale the buyer eventually chooses.
This piece reads the Nikkei Asia announcement as an industrial-design story rather than a capacity story; the wire framed it as a commercial partnership, and that framing is correct, but the more durable read sits in the lineage of the two firms.
