The Japan OOH Audience Measurement Association (JOAA) has begun measuring "Japan OOH Measurement Data," which allows for the evaluation of OOH (Out-of-Home) advertising exposure based on common standards.
This initiative is being advanced with the tripartite agreement of media companies, advertising agencies, and advertisers. Currently, the association is collecting and verifying data and validating its quality. Data will be provided sequentially for media outlets as their verification is completed.
■ Background
In the Japanese OOH advertising market, data has historically been managed using proprietary standards by each company. This has led to discrepancies in evaluation criteria among advertisers and media operators, leaving challenges in making ad placement decisions and optimizing transactions based on a unified standard.
Meanwhile, in major overseas markets, the introduction of common measurement metrics has accelerated the visualization of OOH advertising value and market growth. There is a growing demand in Japan for the development of data infrastructure with high transparency and comparability.
Furthermore, as people's mobility recovers following the COVID-19 pandemic, OOH advertising is being re-evaluated for its unique value, such as "repetitive ad exposure on daily routes," "high visibility and impact," and "flexible targeting based on area and time."
■ About Japan OOH Measurement Data
Data is calculated on an hourly basis, 24 hours a day, 365 days a year, across the following three metrics, broken down by gender and age (in 10-year increments):
・Impressions (VAC): The volume of ad exposure considering visibility. Calculated by multiplying the audience volume around the media by the Visibility Adjustment (VA) factor provided by ROUTE (UK).
・Reach: The estimated number of unique individuals exposed to the advertisement within a certain period.
・Frequency: The estimated average number of times the same person was exposed to the advertisement within a certain period.
This data is generated using a proprietary estimation logic that integrates diverse data sources held by participating data vendors: NTT DOCOMO, INC., unerry Inc., BlogWatcher Inc., and Allunite A/S.
The media currently subject to measurement are those owned by the following media companies (in Japanese alphabetical order):
JCDecaux Japan Corporation, JR East Marketing & Communications, Inc., Tokyu Agency Inc., Path Communications Inc., Metro Ad Agency Co., Ltd., and LIVE BOARD, INC.
The scope of target media, focusing on outdoor and transit advertising, is planned to expand sequentially along with the target areas. Measurement has begun in the Kanto (1 metropolis, 6 prefectures), Kansai (2 prefectures, 4 prefectures), and Tokai (3 prefectures) regions. The addition of vehicle-based media and the expansion of participating media companies are scheduled for July 2026 and beyond.

Acting Executive Director Tanino, Japan Advertising Agencies Association (JAAA):
The development of common metrics for OOH advertising is a crucial initiative for promoting the visualization of media value and the sophistication of advertising transactions. As evidenced by the receipt of the Hideo Yoshida Memorial Award, this initiative is highly significant because it is being advanced through cross-industry consensus. I look forward to the future expansion of data and its application, which will lead to the development of the entire advertising industry.
The development of common metrics in advertising is an extremely important initiative for promoting the visualization of media value and the sophistication of advertising transactions. This activity is the result of collaboration between transit and outdoor media companies and advertising agencies aiming for the development of the entire OOH industry, culminating in the establishment of the Japan OOH Audience Measurement Association (JOAA) after approximately five years of careful and professional deliberation.
The Japan Advertising Agencies Association (JAAA) expresses its respect for the great efforts of everyone involved in this initiative and has decided to present our "Hideo Yoshida Memorial Award" Group Award. We hope that this award will serve as an opportunity for further data expansion and the widening circle of participating companies, leading to the continued development of the entire advertising industry.
■ Future Schedule (Planned)
March 2026: Start of initial data verification. Covers Kanto (1 metropolis, 6 prefectures), Kansai (2 prefectures, 4 prefectures), and Tokai (3 prefectures).
