Company history

In 1804 Shimizu Kisuke, a twenty-two-year-old temple carpenter from Etchu Toyama, settled into a back-alley room behind a print shop in Kanda Kajicho, Edo, and opened a carpentry business on capital of three momme of silver. In the early years he worked the merchant houses around Nihonbashi by day and made household furniture to sell by night. Kanda Kajicho was an artisans’ quarter of carpenters, smiths and sawyers — a district where a provincial master builder could pick up private work — and as his reputation grew he moved out to a shop on the main street of Kanda Shinishicho under the name Shimizuya.

The turn came with the opening of Yokohama in 1859. The second Shimizu Kisuke, who had taken over the business, opened a Yokohama branch and — through the good offices of a client, the shogunal regent Ii Naosuke — took charge of preparing the port, building both government facilities and the foreign trading houses of the settlement. Those buildings had nothing in common with traditional Japanese construction in scale, structure or materials; the master builders learned brickwork and truss framing on site, reading foreign engineers’ drawings. Crucially, the client was a foreign merchant, not a ministry: drawings and money had to be settled face to face. That was the schooling that set Shimizu apart from rivals who leaned on public works.

The second Kisuke went on to build the Tsukiji Hotel and then, in 1872, the First National Bank — designed in-house, by men who had never seen a bank, and remembered as one of the emblematic pseudo-Western buildings of early Meiji Tokyo. As structures grew more complex, a master builder’s experience alone could no longer guarantee quality, and in July 1886 Shimizu brought in an engineering graduate and created a chief engineer post, linking draughtsmen to the site ahead of the trade. Then in 1887, with the third head of the house dead suddenly and the firm strained by losses on a Yokohama sewer job, Shibusawa Eiichi became its adviser. He defined the sales policy as “private building work” — offices, factories, banks and trading houses — and promoted the 29-year-old Hara Rinnosuke to manager. Shibusawa stayed involved for more than thirty years, and the line he drew still runs through the company.

In October 1915 the Shimizu family incorporated the business as a limited partnership with capital of ¥1 million, ending 110 years of sole proprietorship: contracts had grown too large, and construction machinery too costly, for a form in which one man carried unlimited liability. In August 1937 it became a joint-stock company, Shimizu Gumi, and in November it absorbed the partnership while simultaneously opening branches in Nagoya, Osaka and Kyushu — converting a Kanto business into a national one in a single move. War work followed, with branches in Hokkaido (1939) and Hiroshima (1945) and engineers dispatched to military projects overseas. Three days after the surrender in August 1945, the firm reopened in a head office that had survived the bombing, with some 3,500 employees.

In February 1948, under a corporate reconstruction plan, the company took the name Shimizu Construction. Writing off lost overseas assets and cancelled war compensation forced a capital increase to ¥70 million — the first outside capital in the company’s history, and the point at which 140 years of family shop finally faded from the balance sheet. In the same period Shimizu built its technical base: a research laboratory opened in 1946 became the Institute of Technology, and by 1963 it employed around 90 researchers and held 32 patents and 17 utility models, the most in the industry, along with three licensed foreign methods — a fifth of all such licences held by Japanese contractors. Mechanisation investment reached ¥3.1 billion in fiscal 1961, roughly six times the 1956 figure. “A company that sells technology” was the stated motto, on the view that a client’s technical trust came before the order.

Building had always been the trade; the postwar infrastructure boom required civil engineering too. In 1954 Shimizu expanded its civil engineering division and absorbed a subsidiary, taking on roads, dams, tunnels and harbours until civil work supplied about a fifth of sales in the 1960s — ¥11.7 billion of completed civil works in fiscal 1961, seventh in the industry. In April 1961 the company went public on the Tokyo over-the-counter market with capital of ¥3 billion, listing on the TSE second section that October and moving to the first section in February 1962. The order policy was “planned ordering”: pushing hard through the 1959–61 boom, when orders grew 41% a year, then switching to selective bidding in the 1962 downturn — possible only because a year’s backlog stood behind it. Private work ran at 80–85% of orders, and 70–80% of that was negotiated rather than tendered.

When President Shimizu Yasuo died in September 1966, Yoshikawa Seiichi became the first head of the company from outside the founding family — the same man who as vice-president had preached “planned ordering” and “a company that sells technology,” and who argued that in a contracting industry exposed to the swings of demand, nothing but credit could secure a steady volume of work. He meant it literally: when defects appeared in six silos built for a Kobe flour miller, Shimizu redid more than ¥100 million of work at its own expense with the client’s consent. Professional managers have run the company ever since.

Growth outside the contract itself proved harder. A precast-concrete plant opened in 1966 to mass-produce housing grew to six plants and 10,000 units a year by 1972, then shrank away under the assault of the specialist housebuilders. When the 1973 oil shock froze domestic demand, Shimizu incorporated in Brazil and pushed overseas in earnest, eventually working in 34 countries. In July 1978 it committed to becoming an engineering constructor — taking on everything from planning to maintenance, since margins inside pure contracting had stopped growing — and in May 1985 published the “Shimizu Spring Plan,” which aimed to raise non-core businesses from 5% to 35% of the company within ten years. The culture resisted: Shimizu was said to be so cautious it would tap a stone bridge until it broke. President Nomura Tetsuya conceded in 1985 that “solidity alone is not enough” and told the company to think while running.

Then the ground moved. From late 1986, domestic-demand stimulus after the trade friction with the United States set off an unprecedented construction boom in the big cities — precisely the private building market Shimizu was built for. It issued its first unsecured convertible bonds, ¥50 billion, in 1987, more than its entire paid-in capital. In the year to March 1990 it led the industry in sales, orders and recurring profit at once. But the bubble burst that same year; the backlog fell from twice annual sales to about 1.4 times. In February 1991 the company issued SHIMZ-21, which set a ¥3 trillion sales target for 2000 while stating flatly that “the core business is, and remains, construction” — a retraction of the 35% diversification goal barely six years old.

Orders thinned, but investment in how buildings are made did not: roughly ¥50 billion went into labour-saving from 1989, cutting steel-welding labour by 40% and concrete placement by 15%, with the savings intended to fund wages high enough to keep young workers in an industry paying ¥1 million less than manufacturing. Cost-cutting became the main task — ¥30 billion in fiscal 1993, ¥25–30 billion planned for 1994 — and in September 1993 the chairman, then head of the industry federation, was arrested in the general-contractor bribery scandal. The reckoning came in 1998, when Shimizu announced a $1.1B (¥150bn) extraordinary loss to clear bad assets in one pass: real-estate inventory, affiliate restructuring, early-retirement payments. Two consecutive loss years totalled ¥185 billion and consumed nearly nine-tenths of the retained earnings accumulated since 1804. “We are absolutely not permitted to hand the negative legacy to the next generation,” a director said.

The 2000s pushed contractors back into private building as public works shrank, and competition there collapsed into price and schedule. In November 2007 substandard reinforcement was found in a 45-storey condominium tower a joint venture including Shimizu was building in Ichikawa, Chiba — all 407 units already sold. Multiple layers of inspection had been in place, but the affected floors had fallen outside the scope, so the defect passed every check. President Miyamoto Yoichi set up a company-wide “monozukuri strengthening committee” reporting directly to him in January 2008; it produced an illustrated primer, distributed to every employee, in the line of Shibusawa’s The Analects and the Abacus, which Shimizu treats as standing above its management philosophy. In the year to March 2010 the company posted its first consolidated net loss ever, ¥6.85 billion, as the financial crisis cut private capital spending.

Recovery was strong and then abruptly reversed. Consolidated operating profit reached ¥128.8 billion on sales of ¥1.57 trillion in the year to March 2017 — an 8.2% margin that President Inoue Kazuyuki described as, for a manufacturer, “the bare minimum; we have finally become a normal company” — and a record ¥133.9 billion in the year to March 2020. Then in the year to March 2024, on record sales of ¥2.01 trillion, Shimizu reported an operating loss of $175.8M (¥25bn), the first in its listed history: materials and labour inflation, plus the cost of accelerating squeezed schedules, hit contracts priced before the surge, and on private work with no escalation clause the company absorbed the difference itself. Profit recovered as the unprofitable backlog burned off — ¥71.0 billion in fiscal 2024, ¥118.7 billion in fiscal 2025. Meanwhile the search for a third pillar changed method: after in-house ventures from precast housing to the Spring Plan had all failed to stick, Shimizu began buying instead, taking road-paving contractor Nippon Road to a majority via tender offer in 2022 and acquiring marine civil engineering firm Aomi Construction for about ¥25 billion in January 2026 — steps toward the 35% of earnings from non-construction that SHIMZ VISION 2030 demands by fiscal 2030.
