It is now possible to create and connect a Business Manager and a LINE Official Account when creating or editing an advertising account in the Product.
As a result, the following features can be used more smoothly, and improved usability of services provided by LINE Yahoo is expected.

• Features of Display Ads
  
  • Features that require integration with a LINE Official Account (such as ads aimed at gaining friends and linking profile images of LINE Official Accounts)
  • Audience list integration feature
• Measurement tag features
• New cross-service features of LY Ads scheduled to be provided in the future

*As of the implementation date, there are no available features through connecting Search Ads accounts with a Business Manager or a LINE Official Account. Details regarding Search Ads (Shopping) will be announced once finalized.

The changes in the Campaign Management Tool related to this matter are as follows.

A connection feature with Business Manager and LINE Official Account has been added to the advertising account creation and editing screen in the Campaign Management Tool.
If you apply via online signup, you can also create a new Business Manager and LINE Official Account within the same screen.
If you apply through an agency, please create them from each service’s screen.

*The above image is an example of the screen for customers applying through online sign-up. The displayed content is subject to change.

For customers who applied via online signup, connecting to a Business Manager and a LINE Official Account is now required when creating additional advertising accounts on or after the implementation date.
However, connection to a Business Manager and a LINE Official Account will be optional in the following cases.

• When applying through an agency
• When the registered “Address” at the time of ad account creation is outside Japan
• When creating an ad account via the Yahoo! JAPAN Ads API
• For ad accounts already created by March 31, 2026

The "Business Manager" menu under the "Data Integration" tool previously provided in Yahoo! JAPAN Ads Display Ads has been discontinued.
To connect to a Business Manager or LINE Official Account from the Campaign Management Tool, please configure it from the account creation or editing screen.

For customers who applied via online signup and meet the following conditions, creating additional advertising accounts is no longer possible on or after the implementation date.

• If the Business ID has not been integrated
• If you do not have Business Manager permissions (Administrator, Operator, Operator (Data), or Viewer (view only))

*Agencies and customers whose ad account “Address” is registered outside Japan are not subject to the above restrictions and may continue to create accounts.
