28 Firms Raided Over Suspected Bid Rigging in Condominium Repairs — Japan Named the Method Nine Years Ago and Published the Going Rates From 944 Projects

1. March 2016The state wrote the rule

   The condominium management guideline is revised to state that ordering work "must be done properly, with attention to conflicts of interest"

2. January 2017The state named the method

   The ministry issues a notice naming the method: consultants "steer orders toward inflated costs and excessive scope so that the contractor paying them a kickback wins the work"

3. May 2018The state published the going rates

   It publishes the distribution of cost and workload across 944 renovation projects, giving management associations the going rates against which to compare a quote

4. July 2026The same structure was still there

   The Fair Trade Commission raids 28 consultancies and contractors in the Tokai region on suspicion of bid rigging

Publishing information and having someone able to use it are two different things. Japan had about 7.043 million condominium units at the end of 2023, of which roughly 1.37 million were more than 40 years old; in those older buildings, over half of the households are headed by someone aged 70 or above. Work that comes round once every dozen years or so is commissioned by amateurs serving a rotating term. Published rates are only useful to someone with the time and knowledge to compare them against their own quote.

On 28 July 2026, Japan's Fair Trade Commission carried out on-site inspections over large-scale condominium renovation work. The targets were design consultancies and contractors in the Tokai region, 28 firms in all, suspected of repeatedly rigging who won the work. This is the inspection stage; no violation has been established.

Read the headline alone and it looks like fresh wrongdoing has just come to light. In fact the method has a name, and the state is the one that named it.

On 27 January 2017, the Ministry of Land, Infrastructure, Transport and Tourism sent a notice to four industry bodies. Some consultants, it said, "carry out improper manoeuvres so that a contractor paying them a kickback can win the work, and steer the order toward inflated construction costs and excessive scope and specification; to do so they take the consultancy job at a bargain fee, and the result is financial loss to the management association."

That was written nine years ago. Structurally it is the same as what is now suspected.

The state did not sit still. It moved in stages.

The starting point was the March 2016 revision of the guideline on proper condominium management, which added a line stating that the ordering of work "must be done properly, with attention to conflicts of interest." That was the stage of writing down a principle.

The notice of January 2017 went a step further. It accepted that the design-and-supervision method is itself useful, letting a management association without technical knowledge select a contractor transparently, and then set out three concrete cases. In one, an association hired the consultant with the cheapest quote, only to find that the inspection and design were being done by an employee of a contractor; the consultancy, whose brochure claimed a large technical staff, in substance consisted of a non-technical president and one clerk. In another, a design firm told just one of five candidate contractors a smaller quantity of work, so that its quote would come in low. The third was the kickback case. These are not abstract warnings but descriptions of method.

Then, on 11 May 2018, the ministry published its first survey of large-scale renovation work. It covered 944 projects[2] from the preceding three years, setting out the distribution of construction cost and its breakdown, along with the breakdown and volume of consultancy work. It also gave three things worth checking against one's own quote in advance. Whether the breakdown contains excessive items or specifications. Whether the cost per unit or per floor area is high. And whether the consultant's workload has been pressed down unusually low, particularly the supervision component.

Write the principle, name the method, publish the rates to compare against. Broadly, what an administration can do had been done. And in 2026 the same structure became the subject of an antitrust investigation.

Why does the gap persist? Because publishing information and having someone able to use it are two different things.

Look at the conditions facing the buyer. Japan has about 7.043 million[3] condominium units, and multiplying by the 2.2 persons per household from the census gives an estimated 15 million residents, more than a tenth of the population. In most of those buildings, the body that commissions repairs is the management association, which is to say the residents in rotation. Large-scale renovation comes round only once in a dozen years or more. Hardly anyone goes through it twice.

The seller sells this every day. The buyer buys it once or twice in a lifetime. That difference in frequency becomes, directly, a difference in knowledge. The distribution table from 944 projects is the right material, but using it takes both the judgement to know which figures are comparable to your own and the time to compare them.

The buyer, moreover, has been getting weaker. Units over 40 years old numbered about 1.37 million[3] at the end of 2023 and are expected to reach about 2.74 million in ten years and about 4.64 million in twenty. In those older buildings, the share of households headed by someone aged 70 or above is over half[3]. This is what Japan calls the twin ageing, of the building and of the people in it. The same document notes that in such buildings general meetings become harder to run and resolutions harder to pass, and that management associations struggle to find officers.

So the party those rates were published for has grown weaker over these nine years. Correction through disclosure assumes a recipient with the capacity and the time to judge. Where that assumption has broken down, adding more information does not narrow the asymmetry.

From here the design splits two ways. One is to reinforce the recipient, by making outside review, such as the free quote-checking service the state points people to, a standard step rather than an exception. The other is to remove the need to judge at all, by separating the consultant's fee from the construction cost, or barring and disclosing any payment from contractors, so that the contract form leaves no room for the conflict to arise. The first depends on the effort of each management association; the second is carried by the system. What nine years suggest is that the first alone is not enough.

How to turn published data into your own judgement is continuous with the problem taken up in reading official statistics in practice（このサイトの記事）. Policy exclusion and non-take-up（このサイトの記事）, on programmes that exist but do not reach people, has the same shape. What has been made available and what has actually arrived need to be counted separately.
