Establishment of the Japan OOH Audience Measurement Association

On September 18, 2025, thirteen prominent companies in the advertising industry banded together to form the "Japan OOH Audience Measurement Association" (JOAA). This collaborative initiative aims to promote standardized metrics and effective measurement for Out-of-Home (OOH) advertising in Japan, which includes outdoor and transportation ads. The association is based in Chiyoda Ward, Tokyo, under the leadership of Chairman Akihiko Ishikawa.

Objectives of the Association

The primary mission of the JOAA is to improve the transparency and reliability of advertising measurement methods. By creating uniform industry standards, the association intends to help advertisers feel more secure when utilizing OOH advertising. This will be achieved by developing and providing common indicators that can be trusted across the advertising ecosystem, which includes advertisers, advertising companies, and media service providers.

The JOAA also plans to include representatives from both the Japan Advertisers Association and the Japan Advertising Agencies Association as founding members of the board of directors. This will ensure comprehensive representation across the advertising industry.

Background and Necessity

In Japan, the OOH advertising market has faced a challenge due to the reliance on varied standards across different companies for data management. This inconsistency has led to discrepancies in evaluation criteria between advertisers and media companies, making effective decision-making and transaction optimization difficult. Conversely, many international markets have adopted common measurement indicators that have not only clarified the value of OOH advertising but also accelerated market growth.

As mobility is recovering post-COVID-19, OOH advertising is regaining attention due to its effectiveness in reaching audiences in daily life scenarios, such as commuting. Its high visibility and impactful approach allow for flexible targeting based on area and time, highlighting the necessity for shared metrics and data infrastructures that stakeholders in the advertising industry can utilize.

Mission & Goals

The Japan OOH Audience Measurement Association is set to deliver audience data that all members can use while also facilitating the following areas:

• - Optimization of Advertising Planning: Enhance the effectiveness of advertisement placements by using shared metrics.
• - Transparency in Transactions: Ensure clarity and fairness in buying and selling advertising space.
• - Campaign Effectiveness Measurement: Provide tools to visualize and trace the effectiveness of advertising campaigns.

Additionally, the association will operate as a neutral third-party entity, striving to increase the trustworthiness of OOH advertising through sustainable practices and equitable governance.

Strategic Initiatives

The goals of the association include:
1. Continuous provision of OOH advertising measurement data.
2. Establishing an understanding of transparent OOH advertising transactions and developing internationally recognized industry standards.
3. Contributing to the healthy development and expansion of a socially responsible OOH advertising industry.

To realize these aims, the JOAA will engage in various activities such as:

• - Conducting research on OOH advertising metrics.
• - Collecting, analyzing, and utilizing relevant data regarding advertising evaluations.
• - Building and managing necessary databases.
• - Promoting knowledge and public insights into OOH advertising operations and policy recommendations.
• - Facilitating international cooperation and exchange relevant to OOH advertising.

Future Outlook

With a structured organization consisting of a board of directors, general assembly, and committees, the JOAA will start actively recruiting regular and supporting members. By March 2026, it is expected to commence providing measurement data tailored for member companies.

Final Note

The establishment of the Japan OOH Audience Measurement Association marks an important advancement in the outdoor advertising sector. The incorporation of standardized metrics and a collaborative framework promises to enhance the effectiveness, clarity, and reliability of OOH advertising across the nation.
