Webinar on Digital Advertising Risks

On October 23, 2025, Momentum Inc. and Effectual Co., Ltd. will host a significant webinar focused on the recent guidance issued by the Japanese Ministry of Internal Affairs and Communications regarding digital advertising. This marks a pivotal moment as it addresses the growing complexities and risks associated with digital content and distribution in the AI era.

Overview of the Webinar

As artificial intelligence continues to reshape how advertisements are produced and disseminated, the efficiency, speed, and volume of online advertising have surged. However, this rapid evolution presents significant challenges. The mechanisms for auditing and reviewing advertisements have lagged, exposing brands to risks of inappropriate content, regulatory violations, and potential harm to their reputation due to improper placements or misleading practices.

In response to these challenges, the Ministry aims to enhance the transparency and accountability of advertisers. By 2025, they will roll out guidance to ensure responsible advertising practices among businesses. The upcoming webinar will feature expert insights from both Momentum and Effectual, analyzing the dual facets of advertising risk management: review processes and transparency. Attendees will learn about practical strategies to maximize their advertising investments while safeguarding brand integrity.
