Mastering Advertising Regulations Compliance for the Japan Takken Exam

Last updated: April 2026

For candidates preparing for the Japanese Real Estate Brokerage Act examination, commonly known as the Takken exam, understanding advertising regulations is absolutely critical. The Building Lots and Buildings Transaction Business Act (宅地建物取引業法, Takuchi Tatemono Torihikigyo Ho) places stringent restrictions on how, when, and what real estate professionals can advertise. These rules are designed to protect consumers from misleading information, bait-and-switch tactics, and financial harm. Because this topic appears every single year on the exam, mastering it is a non-negotiable step in your preparation.

Core Legal Frameworks Governing Real Estate Advertising in Japan

Real estate advertising in Japan is not governed by a single law, but rather an overlapping framework of national legislation and industry codes. Takken candidates must understand the interplay between these three primary frameworks:

1. The Building Lots and Buildings Transaction Business Act (Takken Act)

This is the primary legislation tested on the exam. Articles 32, 33, and 34 of the Takken Act specifically dictate the timing of advertisements, the prohibition of exaggerated claims, and the requirement to clarify the transaction modality (whether the broker is acting as a seller, agent, or intermediary).

2. Act Against Unjustifiable Premiums and Misleading Representations (Keihin Hyoji Ho)

This consumer protection law applies to all industries in Japan but is heavily enforced in real estate. It strictly prohibits "bait advertising" (おとり広告, Otori Kokoku) and any representations that make a property appear significantly better than it actually is.

3. The Fair Competition Code (Kosei Kyoso Kiyaku)

Established by the Real Estate Fair Trade Council, this code provides the granular, day-to-day rules that real estate agents must follow. It dictates exactly how to calculate walking distances to train stations, how to advertise property ages, and what specific terminology is banned.

Key Advertising Regulations Tested on the Takken Exam

1. Prohibition of False and Exaggerated Advertising (誇大広告の禁止)

Article 32 of the Takken Act prohibits false or exaggerated advertising regarding a property's location, size, quality, environment, or financial terms. Notably, this prohibition applies even if no actual damage is caused to a consumer. Merely publishing the exaggerated advertisement is a violation of the Act. Furthermore, the use of absolute terms such as "Perfect," "Absolute," "Best," or "Unrivaled" (完璧, 絶対, 日本一) is strictly prohibited unless backed by objective, verifiable data.

2. Restrictions on Advertising Timing (広告開始時期の制限)

Article 33 dictates that a real estate broker cannot advertise a plot of land or a building until the necessary administrative permissions are secured. For unbuilt properties, advertising cannot begin until:

• Development Permission (開発許可, Kaihatsu Kyoka) is granted for land development.
• Building Confirmation (建築確認, Kenchiku Kakunin) is obtained for new building construction.

Exam Tip: A common trick question on the Takken exam asks if a broker can advertise a property "while the building confirmation application is pending, as long as they disclose it is pending." The answer is always No. You must wait until the permission is officially granted.

3. Clear Disclosure of Transaction Modality (取引態様の明示)

Article 34 requires brokers to clearly state their relationship to the property in all advertisements. The broker must specify whether they are acting as:

• The Seller (売主, Urinushi)
• An Agent (代理, Dairi)
• An Intermediary/Broker (媒介 / 仲介, Baikai / Chukai)

This must be disclosed not only when the advertisement is placed, but it must be explicitly reiterated when an actual order or inquiry is received from a client.

Specific Rules from the Fair Competition Code

Calculating Walking Distances (The "80 Meters per Minute" Rule)

One of the most famous and highly tested rules in Japanese real estate is the walking distance calculation. By law, walking distance to a station or facility must be calculated at 80 meters per minute. Fractions of a minute must always be rounded up.

Practical Formula/Scenario:
If a property is exactly 600 meters from the nearest train station ticket gate, the calculation is 600 ÷ 80 = 7.5 minutes. Because fractions must be rounded up to the nearest whole minute, the advertisement must state: "8 minutes on foot from the station." It cannot legally say 7.5 minutes or 7 minutes.

Bait Advertising (おとり広告)

Bait advertising refers to advertising properties to attract customers, even though the properties cannot or will not be sold to them. The Fair Competition Code classifies bait ads into three categories:

1. Non-existent properties: Advertising a fictional property.
2. Unavailable properties: Advertising a real property that has already been sold or rented.
3. Properties with no intent to sell: Advertising a real, available property, but refusing to show it to customers in order to push them toward a different, usually more expensive, property.

Common Advertising Violations in Japan
