The Japan OOH Measurement Association (JOAA) has started measurement based on a unified methodology for the "Japan OOH Measurement Data," which enables the evaluation of advertising exposures in OOH advertising based on common standards.
This initiative is being advanced with the three-way agreement of media companies, advertising agencies, and advertisers, and currently, data collection, confirmation, and quality verification are underway. We plan to gradually begin providing data from media that have completed verification.
■ Background
In the Japanese OOH advertising market, companies have historically operated data based on their own unique standards, resulting in inconsistent evaluation standards among advertisers and media operators. This left challenges in making ad placement decisions and optimizing transactions using identical standards.
Meanwhile, in major overseas markets, the introduction of common measurement metrics has accelerated the visualization of OOH advertising value and market growth. Thus, the development of a data infrastructure with high transparency and comparability is also required in Japan.
Furthermore, with the movement of people recovering post-COVID, OOH advertising is once again gaining attention for its values such as "repetitive ad exposure on daily movement routes," "high visibility and impact," and "flexible targeting according to area and time."
■ About the Japan OOH Measurement Data
The data will calculate the following three metrics based on gender and age (in 10-year increments for men and women) at an acquisition frequency of hourly intervals, 24/7/365.
- Impressions (VAC): Ad exposure volume considering visibility. Calculated by multiplying the audience volume around the media by the visibility adjustment (VA) factor provided by ROUTE in the UK.
- Reach: The unique number of people exposed to the ad within a certain period (estimated).
- Frequency: The average number of times the same person is exposed within a certain period (estimated).
This data is generated by integrating various data sources held by participating data vendors—NTT Docomo, Inc., unerry, Inc., Blogwatcher Inc., and Allunite A/S—using a proprietary estimation logic.
Additionally, the media currently targeted for measurement belong to the following media companies (in alphabetical order by Japanese).
MCDecaux, Inc., JR East Marketing & Communications, Inc., Tokyu Agency Inc., Pas Communications Inc., Metro Ad Agency Co., Ltd., LIVE BOARD, INC.
The target media, mainly outdoor and transit ads, are planned to be expanded gradually along with target areas, starting measurements in Kanto (1 metropolis, 6 prefectures), Kansai (2 urban prefectures, 4 prefectures), and Tokai (3 prefectures). Furthermore, from July 2026 onwards, the addition of vehicle media and the expansion of media companies are planned.

Mr. Tanino, Acting Executive Director, Japan Advertising Agencies Association (JAAA)
The development of common metrics in OOH advertising is an important initiative for visualizing media value and advancing advertising transactions. As shown by receiving the Yoshida Hideo Memorial Award, this effort has great significance as it is proceeding based on cross-industry consensus. We expect it will lead to the development of the entire advertising industry through future data expansion and wider utilization.
Developing common metrics in advertising is extremely important to promote the visualization of media value and the sophistication of advertising transactions. This activity came to fruition with the establishment of JOAA after roughly five years of careful and professional discussions, aiming for the development of the entire Out-of-Home (OOH) industry through cooperation among transit and outdoor media companies, and various advertising agencies.
The Japan Advertising Agencies Association (JAAA) pays its respects to the great efforts of everyone involved in this initiative and has decided to award the "Yoshida Hideo Memorial Award" group prize of our association. We hope this award will serve as an opportunity for further expansion of data and participating companies, contributing to the continued growth of the entire advertising industry.
