LINE Yahoo Corporation (hereinafter, LINE Yahoo) has integrated "LINE Ads" and "Yahoo! Ads Display Ads," which were previously offered separately, and has begun providing a new advertising platform, "LINE Yahoo Ads Display Ads." This integration is part of the foundational integration efforts promoted under LINE Yahoo's new product concept, "Connect One." By leveraging Japan's largest media and data across LINE and Yahoo! JAPAN, it aims to achieve more precise ad delivery. "Yahoo! Ads Search Ads" will also be renamed to "LINE Yahoo Ads Search Ads."

Background of the Integration - Evolution of a "Matured" Ad Platform, Combining Improved Targeting Accuracy through Data Integration with Japan's Largest Reach

Since the management integration in 2023, LINE Yahoo has been promoting phased foundational integration under the "Connect One" concept, and this display ad platform integration is part of that effort. By integrating the ad delivery technologies and data that were previously optimized for LINE Ads and Yahoo! Ads respectively, the company aims to realize an advertising platform that combines improved targeting accuracy (optimization model enhancement) for delivering ads tailored to individual interests with Japan's largest reach.

New "LINE Yahoo Ads Display Ads"

This platform will achieve even greater performance and stable ad operations through the following strengths:

1. Integration of two giant advertising platforms, unified ad delivery with Japan's largest reach

・ It will be possible to centrally deliver ads to users of LINE, which has surpassed 100 million monthly active users in Japan (*1), and Yahoo! JAPAN, with 54 million monthly logged-in user IDs (*2), which were previously handled separately.

*1 As of the end of December 2025

2. Cross-platform data utilization and overwhelming evolution of optimization models

・ Data from both LINE and Yahoo! JAPAN services can be utilized across platforms.

Delivery of "LINE Ads" is scheduled to stop (read-only) around late October 2026, and full service termination is planned for around the end of March 2027.
