Japan OOH Measurement Data Launched to Visualize OOH Ad Exposure with Unified Metrics

The General Incorporated Association Japan OOH Measurement Association (Abbreviation: JOAA) has commenced measurement for "Japan OOH Measurement Data," which enables the evaluation of advertising exposure in OOH advertising based on common standards, following a unified methodology.

This initiative is proceeding with the agreement of media companies, advertising agencies, and advertisers. Currently, data collection, verification, and quality assurance are underway. Data provision is scheduled to begin sequentially for media whose verification is completed.

■ Background

In Japan's OOH advertising market, each company has historically operated its data based on its own standards, leading to variations in evaluation criteria among advertisers and media operators. This has posed challenges in making advertising placement decisions and optimizing transactions on a common basis.

Meanwhile, major overseas markets have seen accelerated visualization of OOH advertising value and market growth through the introduction of common measurement metrics. In Japan, there is a growing demand for the development of a data infrastructure with high transparency and comparability.

Furthermore, as people's mobility recovers post-pandemic, OOH advertising is regaining attention for its value in "repetitive ad exposure along daily routes," "high visibility and impact," and "flexible targeting according to area and time slot."

■ About Japan OOH Measurement Data

The data will be calculated based on the following three metrics, with a data acquisition frequency of 24 hours a day, 365 days a year, broken down by gender and age group (in 10-year increments for males and females):

・Impressions (VAC): Volume of ad exposure considering visibility. Calculated by multiplying the audience volume around the media by the visibility adjustment factor (VA) provided by ROUTE, a UK-based company.

・Reach: Estimated number of unique individuals who were exposed to the advertisement within a specific period.

・Frequency: Estimated average number of times the same individual was exposed to the advertisement within a specific period.

This data is generated through proprietary estimation logic by integrating 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 syllabary order):

MC Decaux Co., Ltd., JR East Planning Co., Ltd., Tokyu Agency Inc., Pass Communications Inc., Metro Ad Agency Co., Ltd., LIVE BOARD Inc.

The target media will gradually expand, focusing primarily on outdoor and transit advertising, along with target areas. Measurement has commenced for the Kanto region (1 metropolis and 6 prefectures), Kansai region (2 prefectures and 4 prefectures), and Tokai region (3 prefectures). Furthermore, the addition of vehicle media and an expansion of media companies are planned from July 2026 onwards.

We anticipate that the future expansion of data and its utilization will contribute to the development of the entire advertising industry.

The establishment of common metrics in advertising is an extremely important initiative for promoting the visualization of media value and the advancement of advertising transactions. This activity, where transit and outdoor media companies, as well as various advertising agencies, collaborate with the aim of developing the entire OOH (Out of Home) industry, has culminated in the establishment of the General Incorporated Association Japan OOH Measurement Association (JOAA) after approximately five years of careful and specialized deliberation.

The Japan Advertising Agencies Association (JAAA) has decided to present its "Hideo Yoshida Memorial Award" Group Award to honor the significant efforts of all participants in this initiative. We hope that this award will serve as an opportunity for further data expansion and an increase in participating companies, leading to the continued growth of the entire advertising industry.
