Real estate advertising is not just a tool for generating inquiries. It is also part of the information consumers rely on to make decisions. In Japan, if you fail to comply with the Real Estate Brokerage Act (Takuchi Tatemono Torihiki Gyoho, 宅地建物取引業法), the Act against Unjustifiable Premiums and Misleading Representations (Keihin Hyōji Hō, 景品表示法), and the industry rules on real estate representations, you lose trust before you gain advertising results.
For global investors and English-speaking real estate professionals, this is a distinctly Japan-specific compliance area. In many overseas markets, platform rules and general consumer-protection law may shape advertising practice, but in Japan, operational standards such as station walking time, “newly built” labeling, and bait-ad restrictions are also governed in detail by industry rules and enforcement practice.
Key points in this article
- The Real Estate Brokerage Act regulates exaggerated advertising, the timing when advertising may begin, and disclosure of transaction status.
- The Premiums and Representations Act prevents misleading representations that may cause consumers to misunderstand quality or advantageous terms.
- The industry display rules set detailed standards for items such as walking time to a station, “newly built” labeling, and bait advertising.
- Online advertising also creates risk if listings are not removed promptly after conditions change, so operational controls matter.
Three Rules You Need to Check in Real Estate Advertising
In Japan, real estate advertising should be reviewed against three frameworks together: the Real Estate Brokerage Act, the Premiums and Representations Act, and the Fair Competition Code Concerning Real Estate Representations (Fudōsan no Hyōji ni Kansuru Kōsei Kyōsō Kiyaku, 不動産の表示に関する公正競争規約). Reading only the statutes is not enough to cover the practical detail behind issues such as station walking time or “newly built” labeling.
Not only advertising staff, but also sales teams, property management staff, and anyone involved in reporting to owners should share a minimum common understanding of prohibited expressions.
Advertising Rules to Watch Under the Real Estate Brokerage Act
| Issue | What it means | Practical point |
|---|---|---|
| Timing when advertising may begin | Restrictions on advertising before development permission or building confirmation is obtained | Requires particular care for uncompleted properties |
| Ban on exaggerated advertising | Prohibition on representations that differ materially from the facts | Be careful with definitive claims about views, yield, or future upside |
| Disclosure of transaction status | You must disclose whether you are the seller, agent, intermediary, etc. | Make sure this is not omitted on portals or social media |
The Premiums and Representations Act and the Industry Display Rules
The Premiums and Representations Act is intended to prevent unjustifiable representations that may mislead consumers in their choice. In real estate advertising, the issue arises when a property is made to appear materially better or more advantageous than it actually is.
The industry display rules contain detailed standards for matters such as the rule that 1 minute on foot equals 80 meters, the conditions for “newly built” labeling, area measurements, equipment and facilities, and nearby amenities. It is not enough to simply fill in the fields required by a portal site; you also need an operating process for retaining supporting materials.
In some English-speaking markets, marketing copy may allow more room for soft promotional language so long as it is not outright false. In Japan, however, detailed representation standards often require supportable, standardized descriptions rather than broad sales language.
Bait Advertising and the Risk of Failing to Remove Listings
Bait advertising (otori kōkoku, おとり広告) means using a property that cannot actually be transacted as a way to attract inquiries. This does not refer only to intentionally fictitious listings; it can also include listings left up after a property has already been contracted, or listings not updated after conditions change.
For property management companies and brokerage firms, the operating process for stopping listings is just as important as the process for starting them. Trust is better protected when responsibility is clearly assigned from listing status, application, screening, and contract signing through to deactivation of the advertisement.
This is another area where Japanese practice may feel stricter than what some foreign operators expect. In other markets, outdated inventory may be treated mainly as a quality-control problem, whereas in Japan it can raise a direct bait-advertising compliance issue.
What Property Owners Should Check in Advertisements
Owners should not completely delegate advertising copy without review. They should check rent, floor area, equipment and facilities, building age, transportation access, photos, initial costs, and campaign conditions. In particular, planned renovations, future redevelopment, and assumed yield at full occupancy are all areas where statements can easily become overly definitive.
Advertising is not only about short-term inquiries; it is also a long-term brand asset. Accurate advertising may slightly reduce the number of inquiries, but it also reduces wasted viewings and complaints, and protects the people working on the ground.
Advertising Checklist
Before running an advertisement, you need a process that does not rely only on the instincts of the sales representative. Small wording errors can lead to suspension from portal sites, administrative guidance, or customer complaints.
| Check item | What to confirm |
|---|---|
| Whether the property can actually be transacted | Confirm it is not already contracted or under application |
| Transportation display | Confirm there is a basis for the stated walking time |
| Area and building age | Confirm they match the registry and supporting documents |
| Photos | Confirm they do not create an impression that differs from the current condition |
| Campaigns | Confirm the conditions and deadline are clearly stated |
The Boundary Between Effective Sales Language and Violation Risk
In advertising, the boundary between communicating appeal and making claims that are too definitive is critical. If you write “good sunlight exposure,” you should consider time of day and the impact of surrounding buildings. If you write “high future potential,” you should confirm the certainty of any redevelopment plan and the source behind it.
Good advertising is not advertising that simply stacks strong words together. It is advertising that accurately communicates the conditions, basis, and limitations, and reduces misunderstanding before the inquiry is made. As a result, the quality of viewings improves, and sales and management personnel can focus on their actual work.
Building an Internal Ad Review Process
Advertising regulation will always produce gaps if you rely only on the care and attentiveness of the individual staff member. Before publication, you need an operating process that separates review items among the person entering the property information, the sales manager, and legal or management staff, while also keeping a record of revisions.
Particular care is needed with price changes, campaigns, photos taken before renovation work is completed, distance to the station, and ending listings for properties that have already been contracted. Before trying to increase inquiries, confirm that the advertisement is something you can properly explain after the inquiry arrives. Advertising is the entry point to lead generation, but it can also be the entry point to transactional disputes.
Frequently Asked Questions
Are real estate advertisements on social media also regulated?
A. They can be. Regardless of the medium, if property information is presented to consumers, the applicable rules should be checked.
How is walking time to the station calculated?
A. Under the real estate display rules, there is a standard that 80 meters of road distance equals 1 minute on foot. Care is also needed with rounding treatment.
Is it a problem to keep advertising a property after it is already contracted?
A. Continuing to advertise a property that can no longer be transacted may become a bait-advertising issue.
Can I mention future price appreciation in an advertisement?
A. Avoid definitive statements about future value or yield. Use cautious wording that clearly states the basis and conditions.
