Schedule:

Around spring 2026
*This date is subject to change.

Summary

We will integrate Yahoo! JAPAN Ads Display Ads and LINE Ads, which have been provided as separate products, and launch them as "LY Ads Display Ads."
We will also unify both ad platforms as we start offering the products.
You will be able to manage ads more efficiently.
After the integration, we will focus our development resources on updates to further enhance ad effectiveness and reduce operational workload.

With the launch of "LY Ads Display Ads," Yahoo! JAPAN Ads (including Search Ads) will be renamed LY Ads.

Comments

• Customers using Yahoo! JAPAN Ads do not need to take any action for this migration.
• Customers using LINE Ads will need to migrate to LY Ads Display Ads in the future. We will provide details on the migration process around two months before the launch.
  Until the launch of "LY Ads Display Ads," ad delivery will continue as before.
