Sekisui House began in August 1960 as Sekisui House Sangyo, a $277,778 (¥100m) company spun out of the housing division of Sekisui Chemical, with Sekisui Chemical’s own president, Ueno Jiroo, serving concurrently as its first president. The plan was to industrialise the Japanese house. The problem was that the prefabricated house of the early 1960s cost more than conventional carpentry and looked poorer for the money: sales reached only ¥260m in the year to July 1961 and ¥1.24bn by 1963, while trade commentary of the day named Daiwa House and Eidai Sangyo — not Sekisui — as the fast-growing prefab firms. Three years in, the company carried a cumulative deficit of $250,000 (¥90m), closer to ¥200m once bad assets were counted, and its staff had lost heart.
In June 1963 Tanabe Ken moved across from the executive board of Sekisui Chemical to take the presidency. “This company is a ship about to sink,” he told them. “But I am its captain, and I am prepared to go down with it.” He then made every seconded employee choose — return to Sekisui Chemical, or take the severance and transfer for good — and rebuilt the payroll out of those who stayed.
That October he renamed the company Sekisui House and scrapped the dealer network. Dealers sold houses as a sideline, pushed them without conviction, and rarely understood the building system; from then on Sekisui House employees would do both the selling and the building — direct sales and responsible construction. Rivals avoided the model because it raised selling costs. Alongside it he pushed the product upmarket, launching the two-storey 2D, the economy E and the deluxe F, and it was the F that broke the standing assumption that a prefab house was cheap goods. The company turned an annual profit in 1964, cleared its accumulated deficit and paid its first dividend in 1965, and listed on the second sections of the Tokyo and Osaka exchanges in August 1970, moving up to the first section the following June.

1976Sekiwa Real Estate founded to convert trade-up demand into new orders
1977Grand Maison Nagahori — entry into urban development
197865 branches become independent-P&L “companies within the company”
1979A fifteenth straight year of rising sales and profit
1984Is series — the high-end line that redefined the prefab house
The oil shock of November 1973 cut prefab housing starts from a peak above 200,000 units to about 150,000 by 1975, and the big late entrants — Kanebo, Obayashi Housing — pulled out or retrenched. Sekisui House went the other way and took orders off them. When monetary tightening choked mortgages, it added the industry’s first in-house housing loan to its bank tie-ups, widened its funding from regional and mutual banks down to credit unions, and raised equity at market prices. When material costs exploded, it held its own price increase to 15% against an industry average of 30%, Tanabe overruling the directors who wanted more: “Material prices will settle down soon — we make quite enough at today’s prices.” Cheap, and financeable, the houses sold.
The next constraint was land, so the company manufactured its way around that too. It bought developed sites in bulk from the major developers, sold the land on cheaply, and took the house order on top — the uridate or “sell-then-build” model, against the conventional practice of selling land and house together as a finished package. At the January 1979 year-end it held ¥99.5bn of land, having bought ¥99bn and sold ¥72.5bn in twelve months at a gross margin of 10.1% — a slight loss once the interest on the purchase money was counted, which Tanabe accepted: “If the housing business sells, the company as a whole makes plenty.” Sekiwa Real Estate, set up in Osaka in March 1976 to broker second-hand homes, closed the last gap by feeding trade-up buyers — roughly half of urban demand — back into new orders. In the year to January 1979 sales reached $1.3B (¥304bn) and ordinary profit $90M (¥21bn), a fifteenth consecutive year of rising sales and profit; the profit line passed Taisei and closed on Kajima, and Tanabe declared that “we have got out of being a prefab company and joined the big contractors.”
Underneath sat an organisation built to the same logic. Salesmen were fixed to a territory for years because local carpenters, not prefab makers, held 65% of the market and had to be displaced house by house; branch offices ran logistics, construction and used-home purchasing as regional businesses, growing from 57 to 67 in a single year to the end of 1977, and in 1978 all of them were turned into independent-P&L “companies within the company.” Production was concentrated in three plants of 300 units a month, and purchasing was centralised down to the nails. The range, meanwhile, widened from steel frame into wood, concrete and platform-frame construction and on into ordinary custom houses — the trade called it “a department store of homes” — with the prefabrication ratio per house deliberately cut to buy back freedom of design. That line, from the K type of 1971 through to the Is series of 1984, is what finally changed what a prefab house meant in Japan. Condominiums followed in 1977, urban development after that, and the first ventures abroad — a Dutch acquisition in 1971 that ended in retreat from building into brokerage, and a timber-processing arm in Washington State in 1987.
In the year to January 1991 Sekisui House became the first Japanese housebuilder to pass $7.4B (¥1tn) in sales, and in November 1993 the first to hand over a millionth house; that same year it consolidated its head office into the new Umeda Sky Building in Osaka. Scale brought its own disorder — three design departments competing for products had left 28 separate product names for detached houses alone — and the brands were regrouped by buyer segment rather than price. Then the ground moved: housing starts peaked at 1.63 million in fiscal 1996 and fell without stopping, dropping below a million after fiscal 2008 and reaching only 980,000 even in fiscal 2013, when buyers rushed ahead of a consumption-tax rise.
The reckoning came in the year to January 2010. Sales fell 11% to ¥1,353.1bn and the company posted an operating loss of ¥38.7bn and a net loss of ¥29.2bn, ending the forty-five-year unbroken run of profits that had started in 1964. Gross margin collapsed from 19.2% to 11.6% as write-downs on condominiums and development assets landed on top of the volume decline, and the fixed costs built up through a decade of expansion abroad and into urban development had nothing left to absorb them. The loss lasted exactly one year — sales of ¥1,488.3bn and operating profit of ¥56.3bn followed in the year to January 2011 — but what pulled the company back was not the detached house. It was rental-housing management and remodelling.
So the business was rebuilt around them. The medium-term plan of 2012 named three pillars — built-to-order, stock-type and development-type — and Abe Toshinori was blunt about the alternative: “If we were still a detached-house specialist, as we were a few years ago, we would be shrinking now, and in serious trouble.” Between fiscal 2012 and fiscal 2016 the real-estate fee business grew from ¥393.9bn to ¥469.1bn in sales and ¥17.0bn to ¥31.2bn in segment profit, rental housing profit more than doubled to ¥60.8bn, and international sales tripled to ¥182.1bn on the back of an Australian entry in 2008 and North America Sekisui House in 2010. Consolidated operating profit hit a record ¥184.1bn. A company that had made its money by building a house once and walking away now collected fees for as long as the customer kept it.

In March 2017 Sekisui House bought Woodside Homes, a Utah homebuilder, for about $475.2M (¥53bn). The arithmetic was plain: Japanese starts were stuck in the 900,000s while the United States, with a growing population and a housing shortage, ran above 1.3 million a year — and American detached housing was barely industrialised, which left room to carry across the construction quality control, durable components and design systems Japan had spent fifty years perfecting. Abe Toshinori’s reading of the domestic side pointed the same way: Japan’s carpenters were falling 4–5% a year, from 400,000 then to a projected 140,000–150,000 by 2030, so meeting the same demand would require building 1.5 times as fast. Oregon’s Holt Homes followed in 2021 and Texas’s Chesmar Homes in 2022, widening the footprint from the West into the South.
By fiscal 2023 international sales of ¥511.0bn were 16% of the ¥3,107.2bn group total — six years to move a sixth of the company offshore. Then, in April 2024, Sekisui House paid roughly $4.8B (¥720bn) ($4.94bn) for M.D.C. Holdings of Colorado, acquiring the capacity to hand over some 15,000 homes a year across sixteen states. International sales jumped about 2.5-fold to ¥1,278.5bn in the year to January 2025 — roughly twenty-three times the fiscal 2012 figure — and group sales passed ¥4tn; in 2025 the four American builders were folded into a single Sekisui House U.S.
The same period exposed what the domestic company could not see about itself. In 2017 an organised gang of jimenshi — professional land-title fraudsters — impersonated the owner of a former inn site in Tokyo’s Gotanda district and took ¥6.3bn; the ¥5.5bn loss was under 3% of that year’s operating profit, but the aftermath was not trivial. The investigation report, prepared by four outside auditors and directors, went to the board on 24 January 2018 and never went further than a two-and-a-half-page press release; at that same board meeting chairman Wada Isamu moved to dismiss president Abe, lost the vote, and resigned, whereupon Abe was promoted to chairman. Meanwhile the domestic base kept broadening: the mid-sized general contractor Konoike Gumi, an equity-method affiliate from 2016, was consolidated in October 2019 and contributed ¥269.4bn of sales on a construction cycle unlike housing’s; the Sekiwa property companies were unified as Sekisui House Real Estate in 2020. By fiscal 2023 the stock-related businesses earned ¥128.1bn, close to half of the ¥270.9bn consolidated operating profit.
The core of this decision is that it refused to blame the product or the market for poor sales, and changed both the way of selling and the positioning of the product at the same time. Replacing dealer-led distribution with direct selling and responsible construction by the company’s own employees was a choice to take back, at a known cost, both the point of contact with the customer and the responsibility for quality. Tanabe Ken deliberately took the road that rivals had avoided as unsuited to volume production and volume selling.
The other choice was to go upmarket. At a time when “prefab means cheap” had settled into common opinion, putting the deluxe type at the centre of the range was a declaration that the company meant to keep its distance from price competition and be chosen for quality instead. Tanabe Ken turned a three-year-old company carrying an accumulated deficit into a profitable one within a year, and led it through fifteen consecutive years of rising sales and profit to a stock-market listing; he would later be called the man who remade Sekisui House. Wind up a business that will not sell, or rebuild the way it is sold — this decision is worth revisiting as the judgement of a manager who chose the latter.
The core of this decision is that it declined to treat swings in external demand as a given, and dug demand out for itself on several fronts at once — finance, land, brokerage and range. As the oil shock thinned housing demand and the large late entrants withdrew, Sekisui House lowered the money barrier with its own housing loan, cleared the land barrier with the uridate model, removed the trade-up barrier with Sekiwa Real Estate, and answered the diversification of taste by turning itself into “a department store of homes.” Every one of them ran on the same idea: not waiting for orders, but excavating them.
The profit judgement that held a price rise to half the industry’s, and the reading that a loss on the interest of land purchases would be recovered by the core business, both rested on Tanabe Ken’s feel for the market. Aggressive management temporarily worsened the equity ratio and the interest burden, and sat next to real risk. Even so, the stance that demand is created rather than awaited delivered fifteen straight years of rising sales and profit in the teeth of the oil shock, and a level of profit that closed on the major general contractors. There are moves available before you conclude that low growth means you cannot grow — Sekisui House in this period puts that question to industries far beyond its own.
How long can management by giving authority away last?
The core of this decision is that, in the middle of rapid growth, it deliberately handed authority down to the sales front line. Given that Tanabe Ken had already by 1975 built a chain of command that decided on the spot and left the paperwork until later, the “company within the company” scheme of 1978 was not an idea that occurred to someone one morning; it was the point at which one president’s personal way of deciding was extended into a design principle for the whole organisation. Treating 65 branch offices as independent-P&L “managers,” and judging them on a measure as simple as value added per head, appears to have worked as a device against the bureaucratisation that tends to overtake a growing organisation.
That said, this structure also depended heavily on a scale at which Tanabe himself could grasp every branch directly, and on a self-contained business model of direct sales and responsible construction. Keeping head office deliberately small and holding to “instruct but do not manage” rests on the premise that the top can see all the way to the edge, and how that decentralising philosophy would change once the company grew further was not yet visible at the time. Even so, establishing early a mechanism that demanded the awareness of a merchant from the field, against the managerial problem of the day — the rigidity of large organisations — makes this instructive for anyone thinking about how Sekisui House was run afterwards.
The core of this decision is that it re-sorted, in a market that had entered maturity, the proliferation of product names that expansion had produced. A structure in which three design departments generated products in competition with one another created development energy, but behind it swelled the product line to 28 names for detached houses alone, which if anything blurred the outline of each individual brand. Rebundling the brands by buyer segment rather than by price band can be seen as an attempt to recover appeal without throwing away the fruits of that diversification.
Even so, the reorganisation at this point went no further than putting the product names into families; it did not reach into cutting the number of products themselves or the parts count. As the qualified “in the future” in managing director Urushitani’s words suggests, whether the brand tidy-up could be carried through into a rethink of the cost structure remained a question for later. Played into a headwind of weakness in the Tokyo metropolitan market and deteriorating financial income and expenses, whether this move ended as a mere renaming or extended into the rationalisation of development and production looks like the fork in the road on which the management of Sekisui House would afterwards be judged.
What this affair raises is less the fraud itself than the shape of the governance the fraud exposed afterwards. The chairman, with no trace of involvement in the transaction, stepped down; the president, who had been first to put his seal on the approval document, was promoted to chairman and leads the present structure — an inversion in which the one bearing the heavier responsibility remained and the lighter one left, played out inside the board itself. The investigation report, commissioned precisely to bring outside eyes to bear, was sealed because of that third-party character and placed beyond the reach of shareholders. That an institution can be well designed and still not function is written plainly here.
The shareholders’ meeting did, however, re-elect the incumbent management. One may read that as strong results outweighing doubts about governance. But most of the loss remains unrecovered, and the attribution of responsibility that the report framed as “heavier the higher one sits” was left without ever taking a definite form. How far a company can describe its own failure in its own words once the crisis has passed — the land-fraud affair seems to have left Sekisui House with that question, weightier than the size of the loss.
