Company history

In April 1959 Omura Susumu, who had been working at Tokyo Tungsten, set up Sintered Metal Industry (焼結金属工業) in Tokyo to make sintered filter elements for pneumatic lines. Pneumatics is a field with a low technical barrier compared with hydraulics or electrical control, and no single product in it separates one maker from another for long. What separated SMC was decided early and elsewhere: its customers — machine-tool and automobile makers — wanted specifications that no assembly of bought-in parts could satisfy, so the company set out to cover the entire pneumatic process itself.

The build-out took a decade, taken one segment at a time. Finished auxiliary equipment came in September 1961, then compressed-air purification gear, then cylinders in June 1970 and solenoid valves in January 1971. By 1971 SMC could make every element of the pneumatic circuit — air preparation, drying, pressure regulation, directional control — with the sole exception of the compressor. Twelve years after starting as a supplier of filter parts, it had become a maker of finished equipment that took on the customer’s process rather than feeding it components.

The coverage, not any one technology, was the moat. Breadth of range made SMC convenient to buy from and awkward to leave, and by the early 1970s the industry no longer read it as a parts maker but as a house that could design a whole pneumatic system. Omura himself put it plainly: the company’s connection with air had simply grown. Yet integration alone did not pay — sales in the year to March 1971 were only $9.8M (¥4bn). What it had built was the precondition for the delivery model that followed.

Alongside the integration, SMC designed its channel against the grain of the trade. With around 240,000 catalogue items, letting each distributor stock what it liked would have produced surplus and shortage at the same time, so SMC forbade its roughly 97 distributors to hold inventory at all, centralized stock at head office, and made head office directly answerable for price, delivery and quality — an unusual arrangement for industrial-equipment distribution. Around that it built its own network of five sales offices and thirty-eight sub-offices, each carrying profit-and-loss responsibility, selling direct wherever it could. By the year to March 1976 sales passed $36.3M (¥11bn), with Toyota, Denso, Hitachi, Fuji Electric and Chiyoda Corporation among its customers.

The mechanism that made this work was to stock not finished goods but roughly 5,000 basic forms, machined into hundreds of thousands of final variants only once an order arrived by fax from a sales office. Demand planning was handed to staff hired specifically as mathematics graduates, who set stock levels by statistical inference — a peculiar practice for an industrial-equipment maker of the day. An online order system went live in 1983, and average time from order to delivery came down to within 48 hours. In a category where technology does not separate suppliers, delivery and range become the basis on which customers choose; SMC accepted the inventory risk onto its own books and took high margins in return.

In April 1986 the company dropped its founding name for SMC Corporation — the initials of Sintered Metal Company, used as a product trademark since the start and as the name of its overseas subsidiaries since an Australian affiliate in 1967. Overseas customers already knew it as SMC, and the gap with the Japanese legal name had become an obstacle. Sales and service networks covered some thirty countries by the time SMC listed on the Second Section of the Tokyo Stock Exchange in December 1987. By then pneumatics accounted for more than 90% of sales, domestic share had reached 42% against 21% for the runner-up, world share was about 10%, engineers made up a quarter of the workforce, and ordinary profit margins ran at 11–13%.

In 1989 Takada Yoshiyuki, who had been involved since the founding years as senior managing director, became president and ran the company top-down for the next fifteen years. The listing he inherited had never been about money: the month after it, Omura told analysts that the $195.1M (¥25bn) of domestic capital expenditure planned through the year to March 1992 could be covered out of profit and depreciation alone. What the capital market gave SMC was not the sum raised but the room never to have to stop investing — which is what a model that ties up cash in plant and stock actually needs.

Takada’s organizing idea was holon management: break the company into small self-directed units. Partly this was conviction that authority belongs on the floor, partly arithmetic — with 300,000 items, even paperwork could no longer be centralized. Four sales offices were split into fifteen with sub-offices beneath them, and the plants were divided into roughly 160 groups competing on their own methods. The root ran deeper: for thirty years units had calculated their own gains and losses without going through accounting, a practice the company called 油算 — profit responsibility pushed below the level of the division.

The same instinct governed capacity. Takada held that if demand looked likely, the plant should already be there, and put investment in ahead of visible orders, turning capacity itself into a lead over rivals. The forecasts underwriting those decisions were not intuition: a dedicated team of four or five mathematics graduates worked them with statistics, and Takada credited that — “taking the direction of doing forecasting scientifically” — with giving him the confidence to commit. In 1996 he set a 10% overseas-production target against the strong yen, and in 2000 SMC began manufacturing in Beijing on a site of some 60,000 tsubo — the first attempt to reproduce abroad not just output but the inventory-backed delivery design itself.

Through the 2000s and 2010s SMC copied its domestic design onto every region it entered rather than simply adding capacity: base-form stock plus final machining, sited next to the industrial clusters it served, with head office managing global demand on one statistical model. Beijing was followed by Shanghai in 2003 and plants across China; Germany, the Czech Republic and Poland in Europe; and in 2009 a plant at Noblesville, Indiana for North America. Capital expenditure reached $230.5M (¥23bn) in fiscal 2013, of which $154.7M (¥15bn) went overseas. Sustaining roughly ¥20 billion a year of investment was a decision only a very long-horizon owner could keep making, and few competitors matched it — which is where the gap in world share came from.

The model also proved its worth in the downturns. Through the collapse after 2008 SMC declined to cut inventory to the bone, and when demand returned it could ship while others quoted lead times. Overseas sales rose from about 10% of the total in 2000 to around 70% in the 2010s, and operating margins settled near 30%. In 2016 an offshore research house alleged accounting irregularities and the shares fell 35%; SMC denied it, and the margins that followed answered the charge — though the episode showed how hard the model is to read from outside.

In July 2004 Takada stepped up to chairman and handed the presidency to Maruyama Katsunori, a career employee who had joined SMC in 1970; Maruyama ran the company for the next sixteen years. In April 2021 the presidency returned to the founding family when Takada’s eldest son, Takada Yoshiki, succeeded him. The point is not dynasty for its own sake but what the business rests on: committing capital years before demand appears, and holding stock others refuse to hold, requires standing that survives quarters of weak numbers. The founding-era Takada had that standing; his successor inherits a company where the family’s asset-management vehicle holds under 10% of the shares and where the June 2022 vote to elect him drew 89.7% support. Whether a model built on personal authority can now run on the consent of minority shareholders is the question left open.
