Why You May Need a Lawyer

Advertising and marketing law can be complex and fact-specific. You may need a lawyer when you face any of the following situations:

- Designing claims for a new product where evidence and wording matter, such as health benefit claims, nutritional statements, or performance guarantees.

- Receiving a consumer complaint, an administrative inquiry, or an enforcement notice from a government agency or a consumer organization.

- Planning promotions or prize campaigns that might trigger limits under the Act against Unjustifiable Premiums and Misleading Representations.

- Engaging influencers, affiliates or third-party agencies and needing compliant disclosure and contract terms.

- Investigating or defending allegations of trademark infringement, unfair competition, or false advertising.

- Collecting, storing or using personal data for marketing - ensuring compliance with the Act on the Protection of Personal Information (APPI) and related obligations.

- Handling cross-border marketing where jurisdiction, applicable law and consumer protections raise additional issues.

- Negotiating or drafting contracts with advertisers, media owners, platform providers or marketing agencies.

- Responding to industry self-regulatory complaints such as those handled by advertising review bodies.

In these situations a lawyer can help assess legal risk, prepare compliant materials, negotiate with regulators or complainants and represent you in administrative or civil proceedings.

Local Laws Overview

The most relevant national laws and legal frameworks that apply in Nagasaki include the following categories. Local enforcement and support is available through Nagasaki Prefecture offices and local consumer centers, but the substantive rules are national.

- Act against Unjustifiable Premiums and Misleading Representations - governs false, exaggerated or misleading representations in advertising and restricts the value and frequency of premiums and prizes used to promote sales. It is central to consumer protection in advertising and is enforced by consumer authorities.

- Act on Specified Commercial Transactions - sets mandatory disclosure rules and cooling-off or cancellation rights for specified direct sales, telemarketing, mail-order and online sales to protect consumers from unfair practices.

- Consumer Contract Act and general civil law - protect consumers from unconscionable terms, unfair contract practices and defective products or services. These laws provide remedies in private disputes.

- Act on the Protection of Personal Information (APPI) - requires proper handling, notification and often consent for personal data used in marketing, including requirements for cross-border data transfers and data security measures.

- Unfair Competition Prevention Act and Trademark Act - protect against misleading use of trade names, trade dress and trademarks, and prohibit certain deceptive representation and misappropriation of business identifiers.

- Food Labeling and Pharmaceuticals/Cosmetics regulations - the Food Labeling Act and Ministry of Health, Labour and Welfare rules regulate claims about food, supplements, pharmaceuticals and cosmetics, especially health-related claims and advertising of prescription drugs.

- Industry self-regulation - many industries maintain advertising codes and review bodies, such as advertising review councils, the Japan Advertising Review Organization and trade association guidelines. These can lead to voluntary corrections or sanctions and are often consulted before regulatory enforcement.

- Local enforcement and consumer support - Nagasaki Prefectural consumer affairs offices and local consumer centers accept complaints, provide guidance and coordinate with national agencies for enforcement where appropriate. The Nagasaki Bar Association provides local legal resources and referrals for litigation or disputes.

Frequently Asked Questions

Do I need to substantiate every claim made in an advertisement?

Yes. Claims about product performance, health benefits, savings or comparisons with competitors should be verifiable and supported by appropriate evidence. The level of evidence needed depends on the nature of the claim - especially for health, medical or scientific claims, where rigorous data or approvals may be required. Unsubstantiated claims risk administrative actions, consumer lawsuits and damage to reputation.

What is the Act against Unjustifiable Premiums and Misleading Representations and why does it matter?

This law targets misleading advertisements and improper use of premiums and prizes. It prohibits advertisements that deceive consumers about a product or service and restricts the type, value and frequency of giveaways or prize campaigns. Noncompliance can lead to corrective orders or sanctions from consumer authorities and can require businesses to stop campaigns or compensate consumers.

Are there special rules for online advertising and e-commerce?

Yes. Online sellers must meet disclosure requirements under the Act on Specified Commercial Transactions, including providing seller identity, prices, delivery terms, refund and cancellation policies. In addition, online platforms must ensure that marketing does not mislead users, that influencer posts are properly disclosed, and that personal data collected for targeting complies with APPI.

How should influencer marketing be handled to stay compliant?

Influencers and advertisers should disclose material relationships and sponsorships clearly and prominently. Claims made by influencers must be accurate and substantiated. Contracts should set out responsibilities, and advertisers should supervise influencer content to reduce the risk of misleading statements.

Can I use competitor names or customer testimonials in ads?

Using competitor names in factual comparisons may be allowed but must be truthful, not misleading and should not unfairly disparage the competitor. Customer testimonials can be used if they are genuine, represent typical results, and do not mislead about outcomes. Fabricated testimonials, undisclosed incentives for positive reviews, or cherry-picked results can lead to enforcement action.

What protections exist for consumer data used in marketing?

Under the Act on the Protection of Personal Information, businesses must handle personal data lawfully, obtain appropriate consent when required, publish privacy policies, implement security measures and follow rules on cross-border transfers. Use of sensitive personal data or highly targeted profiling raises additional compliance requirements.

What happens if a consumer files a complaint in Nagasaki?

Local consumer centers in Nagasaki will receive complaints and may mediate disputes or forward serious cases to national agencies. Depending on the issue, authorities can issue guidance, request corrective action, impose administrative orders or refer criminal matters to prosecutors. Businesses should respond promptly to investigations and consider legal counsel when disputes escalate.

Are there industry codes I should follow even if not legally required?

Yes. Many industries maintain codes of conduct and self-regulatory review bodies. Following these codes can reduce legal risk, avoid complaints and help manage public trust. Self-regulatory decisions do not replace legal obligations, but failure to follow them can attract enforcement or reputational consequences.

What are the risks of running a cross-border ad campaign targeting Nagasaki residents?

Even if the advertiser is based outside Japan, Japanese laws can apply if the advertising targets consumers in Japan. That means compliance with Japanese disclosure rules, consumer protections and data laws may be required. Jurisdictional complexity can make enforcement and dispute resolution more complicated, so local legal advice is recommended for cross-border campaigns.

How do I find a lawyer in Nagasaki who understands advertising and marketing law?

Look for lawyers or law firms with experience in consumer protection, intellectual property, data privacy and commercial contracts. The Nagasaki Bar Association can provide referrals. Seek lawyers who have handled administrative proceedings before consumer authorities, who know industry self-regulation, and who can work with marketing teams to prevent problems before they arise.
