Two years have passed since Japan's stealth marketing regulation (Premiums and Representations Act Article 5(3)) took effect on October 1, 2023. After an initial outreach period, the Consumer Affairs Agency began full-scale enforcement in 2024-2026. This article covers the latest enforcement cases, PR disclosure standards, and corporate compliance responses.

Stealth Marketing Regulation Overview

Legal Basis

Premiums and Representations Act Article 5(3) (effective October 1, 2023):

> Representations relating to the transaction of goods or services that are difficult for general consumers to identify as a business's representation.

This is a third category added to the existing misleading representation (1) and disadvantageous representation (2) types, with specific content defined by Consumer Affairs Agency notices and operational guidelines.

Scope of Regulation

  • Business (advertiser): Subject to regulation. Liable for measures orders
  • Influencers/affiliate marketers: Not directly regulated
  • Advertising agencies/PR firms: May be deemed business operators depending on circumstances

Elements of Violation

  1. The communication is a business's representation (with business's request/involvement)
  2. Difficult for general consumers to identify as a business's representation

In short, if a business provides cash, products, or benefits to induce a post, a post without clear PR disclosure constitutes a violation.

2024-2026 Enforcement Cases

Major Measures Orders

Case 1: Esthetic Salon Chain (March 2024) - Violation: Asked customer referral program participants to post reviews without PR disclosure - Action: Measures order, publication - Notable: "Discount-incentivized referrals" deemed "consideration"

Case 2: Cosmetics Brand (August 2024) - Violation: Provided products + draft text to influencers requesting posts without hashtags - Action: Measures order, publication - Notable: Non-use of SNS "tie-up" disclosure feature flagged

Case 3: Hotel Chain (January 2025) - Violation: Invited 10+ bloggers for stays requesting articles, with PR disclosure in small text at article ends - Action: Measures order, publication - Notable: Visibility of PR disclosure issue (small font, light gray)

Case 4: Health Food Manufacturer (June 2025) - Violation: Asked bloggers to review via affiliate program with only "cooperation" notation - Action: Measures order, publication - Notable: Vague terms like "cooperation" and "support" are non-compliant

Case 5: Apparel Brand (November 2025) - Violation: Provided products to multiple TikTok creators requesting video posts without PR disclosure - Action: Measures order, publication - Notable: Short-form video platforms (TikTok, etc.) also require clear PR disclosure

Case 6: E-commerce Mall Seller (February 2026) - Violation: Had own employees create multiple reviews to manipulate star ratings - Action: Measures order, publication - Notable: So-called "sakura reviews" (fake reviews) clearly violate

Cumulative Enforcement (as of May 2026)

  • Measures orders: ~20 cases
  • Warnings (below measures order): dozens
  • Caution/guidance: many

PR Disclosure Standards

Compliant Notations

✅ #PR ✅ #広告 (Advertisement) ✅ #プロモーション (Promotion) ✅ #タイアップ (Tie-up) ✅ 【Product Provided by ○○ Company】 ✅ "This post features a product provided by ○○ Company"

Non-Compliant Notations (Violation Risk)

❌ #PR placed inconspicuously in comments or article end ❌ Font color same/similar to background ❌ Vague terms like "cooperation," "support," "thanks to ○○" ❌ Only "sapo" (cooperation abbreviation) without advertiser name ❌ Buried in many hashtags ❌ Brief display in Stories

Consumer Affairs Agency Operational Standards

The agency's operational guidelines (formulated October 2023) consider the following factors:

  1. Placement: Position at the beginning or in a prominent location of the post
  2. Visibility: Size and color visible during normal viewing
  3. Clarity: Clear terms like "PR," "Advertisement," or "Tie-up"
  4. Persistence: For videos, continuously displayed throughout viewing

Corporate Compliance Response

1. Guideline Preparation

Codify in internal marketing guidelines: - Stealth marketing regulation overview and internal responsibility structure - Explicit notation in contracts with influencers, affiliate marketers, and PR agencies - Violation response flow (discovery, reporting, remediation)

2. Contractual Clauses

Incorporate the following into contracts with influencers and PR agencies: - PR disclosure obligation clause: Mandatory "#PR" etc. notation on all posts - Pre-approval obligation: Right to check disclosure content before posting - Liability allocation: Damages provisions for violations - Acceptance condition: No payment if appropriate PR disclosure is absent

3. Monitoring System

  • Post-submission verification: Confirm actual posts by commissioned influencers
  • Third-party audit: Consider external audit for large-scale campaigns
  • Rapid response to discovery: Request correction within 72 hours of identifying improper notation

4. Internal Training

  • All marketing department members: Stealth marketing regulation overview, appropriate PR disclosure
  • Managers: Violation discovery response flow
  • Legal department: Procedures for legal review of individual matters

Violation Risks and Response

Anticipated Risks

  1. Measures order (administrative penalty): Publication + recurrence prevention measures
  2. Brand damage from publication: Consumer Affairs Agency website + media coverage
  3. Criminal penalty for measures order violation: Up to 2 years imprisonment + ¥3M fine
  4. Shareholder/business partner litigation: Breach of duty of due care, compensation claims
  5. SNS firestorm: Boycotts, brand reputation decline

Response on Discovery of Violation Suspicion

  1. Immediate confirmation of facts (post content, contracts, consideration)
  2. Lawyer consultation (Consumer Affairs Agency response strategy)
  3. Corrective measures (post correction/deletion, PR disclosure addition)
  4. Consideration of voluntary disclosure before publication (mitigating factor)
  5. Recurrence prevention planning and implementation (contract revision, training enhancement)

Lawyer Involvement Necessary

Preventive Measures

  1. Guideline creation/revision: Reflecting industry-specific issues
  2. Contract template preparation: Influencer and PR agency contracts
  3. Advertising review system construction: Pre-posting legal review process
  4. Internal training: Department-specific curriculum provision

Post-Discovery Response

  1. Consumer Affairs Agency investigation response: Defense statement preparation, hearing attendance
  2. Measures order response: Examining cancellation suit possibility
  3. Damages response: Recourse against influencers/agencies
  4. Shareholder derivative suit response: Addressing breach of duty allegations

Conclusion

Two years into stealth marketing regulation, Consumer Affairs Agency enforcement has steadily progressed. Cumulative measures orders of ~20 cases and severe brand damage from publication mean that the "if no one notices" mindset no longer works.

Essential corporate response: - Thorough clear PR disclosure (#PR, #広告, #タイアップ, etc.) - Explicit notation in contracts with influencers and PR agencies - Monitoring system construction - Rapid remediation flow for violations

Three-way coordination among marketing, executive, and legal enables compliance and brand value protection.
