The Bid Was Supposed to Be Competitive
Inside Japan’s 42-Company Condominium Repair Case

A condominium repair project can look mundane from the street: scaffolding, mesh, workers moving floor by floor, fresh sealant around windows and a repainted exterior. Financially, however, it is often the largest procurement decision a residents' association will make for years. The money comes from reserve funds accumulated month after month by owners who may never have commissioned a construction project in their lives.

That is why Japan's latest bid-rigging case reaches beyond competition law. On September 28, the Japan Fair Trade Commission found unlawful coordination involving 42 companies around major repair work commissioned by condominium associations in Tokyo and six surrounding prefectures. Jiji Press reported that the case covered 171 projects. Thirty-seven companies were ordered to pay roughly ¥1.6 billion in surcharges, and 38 received cease-and-desist orders.

A competitive process in which the winner was already being chosen

The JFTC described two related groups of conduct. One involved projects for which Renosys Corporation had been hired as the design consultant; the other involved projects handled by Sho-Sekkei. In the first group, the commission identified 36 contractors plus Renosys. In the second, it identified 19 contractors plus Sho-Sekkei. Because some companies overlapped, the total number of infringing companies across the case was 42 rather than the sum of the two lists.

According to the commission, companies established what it called a juchu kyoryoku kankei—a relationship of cooperation over winning orders. For each project, a prospective winner was selected. Other contractors then helped that company win, including by submitting prices communicated to them or declining to participate in the comparison process.

The consultant role is what makes the case unusually consequential. The JFTC defines design-consulting work here broadly: building-condition surveys and diagnosis, preparation of design documents and specifications, assistance in selecting the contractor, and construction supervision. In other words, the consultant is hired in part to reduce the knowledge gap between homeowners and specialist contractors.

The planned budget belonged to the buyer

The commission uses a specific term, sekkei yosan, or "design budget," meaning the amount the condominium association plans to spend on the major repair project. That is commercially sensitive information. It tells a seller roughly how much room the buyer has.

The JFTC found that the consultants supplied prospective winners and related contractors with budget information obtained through their consulting work and, in some instances, carried out consulting work while taking the intended winner's preferences into account.

The residents were not only buying waterproofing, paint and scaffolding. They were paying for a procurement process that was supposed to compare those things honestly.

The separate issue of consultant fees

The JFTC also said its investigation confirmed payments from contractors to Renosys or Sho-Sekkei when a contractor that had received project information won the work. The commission described the payments as a certain percentage of the construction contract price and warned that, depending on the information being supplied, such payments can distort free competition among contractors.

The official release does not state a percentage. Jiji Press reported that the payments were about 5% of the contract value and described them as "information fees" and similar payments. Japan.co.jp treats that 5% figure as a reported figure, not as a number independently stated in the JFTC's main release.

The distinction matters. The commission did not say that every payment between a construction company and consultant is automatically unlawful. It focused on the relationship between the payment, the information supplied and the competitive process. It also sent guidance to three industry associations and asked them to circulate the material to members.

Why condominium repair procurement is structurally vulnerable

A condominium board is a peculiar buyer. It can control a large reserve fund but have little institutional memory. Directors rotate. Most are not full-time construction buyers. Specifications are technical, bids can run into hundreds of millions of yen, and poor quality may not become obvious until years after the scaffolding has been removed.

That information gap is one reason Japan widely uses a design-and-supervision model in which a consultant helps define the work and then a separate contractor performs it. Government material citing the fiscal 2021 major-repair survey shows that roughly 80% of surveyed projects used the design-and-supervision approach.

Separation can create a useful check: the party designing and supervising the work is not the party earning the construction margin. But the safeguard depends on independence. If the adviser is financially or operationally aligned with a contractor, the structure can produce the appearance of oversight without its substance.

The warning dates back to 2017

Japan's housing ministry had already identified the risk almost a decade ago. In January 2017, the Ministry of Land, Infrastructure, Transport and Tourism warned condominium-related organizations that some design consultants were said to be acting in conflict with the interests of the associations that hired them.

In 2018 the ministry followed with its first large empirical survey of major condominium repair projects, covering 944 cases. Its public explanation went unusually far: it described a conflict-of-interest example in which a consultant takes a low consulting fee, then works to steer the construction contract toward a company that pays it a back margin, potentially inducing an inflated project price or excessive specifications.

That history changes how the 2026 case should be read. It is not evidence that authorities discovered an entirely new vulnerability. It is evidence that a vulnerability publicly identified in 2017 could still mature into an enforcement case nine years later.

Japan's aging condominium stock makes the stakes larger every year

The case arrives as Japan's postwar condominium stock moves into old age. MLIT maintains current statistics for the total condominium stock and for buildings more than 40 years old. In the immediately preceding 2024 year-end data, about 1.48 million units were already in buildings over 40 years old. The ministry projected about 2.93 million such units by 2034 and about 4.83 million by 2044.

Age changes the economics of repair. A first major project may focus heavily on exterior walls, waterproofing and sealants. Later cycles can bring doors, windows, water systems, mechanical parking equipment and other expensive components into the program. Material and labor inflation add another layer.

If a reserve fund is insufficient, owners face unpleasant choices: increase monthly contributions, levy a one-time assessment, borrow, reduce scope or defer work. In that environment, genuine price competition is not an abstract antitrust value. It is one of the mechanisms that protects the building's finite repair capital.

A low consulting fee can be expensive

MLIT's 2018 work did not tell associations simply to hunt for the lowest consultant quote. It encouraged them to compare the consultant's actual workload and to ask whether construction-supervision time was implausibly low. The concern is intuitive: an adviser cannot be judged solely by the fee paid directly by the association if other revenue may be tied to which contractor wins.

That turns procurement design into a governance issue. Who pays the consultant? What business relationships exist with candidate contractors? Who compiles the bidder list? Are all bidders pricing the same scope? Who can see the budget ceiling and competing bids? How are late withdrawals or unusually similar estimates investigated?

Companies are beginning to respond

Sumitomo Mitsui Construction said its subsidiary SMCR received both a cease-and-desist order and a surcharge payment order. The parent company said SMCR had cooperated fully since an April 23, 2025 on-site inspection and that the group would strengthen supervision and recurrence-prevention measures.

Haseko Reform also posted notice on September 28 that it had received the JFTC's orders. How each company ultimately responds—accepting the orders, contesting aspects of them, changing compliance systems or addressing individual condominium associations—requires continued company-by-company reporting.

The housing ministry moved the next day

On the day of the JFTC action, MLIT circulated information to condominium associations and unit owners on consultation channels and procurement safeguards. One day later, September 29, it announced a new "Study Group on Proper Procurement for Major Condominium Repair Work." The first meeting is scheduled for October 19.

The group is expected to examine what associations should watch for and how the market can secure appropriate contractors and advisers. The timing suggests the enforcement case may become a policy event as well as an antitrust case.

For years, government guidance largely relied on information, warnings, cost benchmarks and voluntary care by associations. A case in which the competition authority has now mapped out a concrete coordination mechanism raises a harder question: whether conflict disclosure, consultant independence and tender controls need more formal safeguards.

This was residents' money

Public bid-rigging is easy to frame: taxpayers pay the bill. Condominium repair is different but no less tangible. The buyer is a private association made up of households. Its capital is the reserve fund those households have built over years.

That makes this case a story about aging Japan as much as corporate conduct. More old buildings mean more large repair contracts. More expensive repairs mean greater pressure on reserve funds. Older owners can have less ability to absorb sudden assessments. Every percentage point lost to a distorted procurement process is therefore money unavailable for the building's next repair cycle.

When the scaffolding comes down, residents can see a clean facade. They cannot see whether the competition that selected the contractor was genuine. The lesson of the 42-company case is that the invisible part of a repair project—the rules by which the money is awarded—may be as important as the work itself.
