Display Ads (Auction): Launch of in-stream ads

Product

Yahoo! JAPAN Ads Display Ads (Auction)

Tool

Campaign Management Tool

Summary

We will launch Yahoo! JAPAN Ads Display Ads (Auction) in-stream ads (in-stream ads), which deliver ads within video programs.

Instream Ads allow you to deliver video ads in ad places within programs offered by video streaming services. In addition to PCs and smartphones, you can also deliver ads to connected TVs (TVs with internet access), expanding your reach. You can also select the video length to suit your product or service.

Schedule

• September 24, 2025: start account setup procedures.
  *After completing the procedures, you can add ads through the Campaign Management Tool.
• Early October 2025: start delivery
  *For details on how to use this service, contact our sales representative. The schedule is subject to change.

Notes

• In-stream ads will be available only to some advertisers. For details, contact our sales representative.
• Added ads are subject to review by both the video streaming service and Yahoo! JAPAN Ads.
• For in-stream ads, a viewable impression will be counted from the start of the video view. This differs from standard video ads in Display Ads (Auction).
