Summary
As previously announced in the "Integrated Business ID," we are currently integrating Yahoo! JAPAN Business ID and LINE Business ID.
Refer to the following sections for details on the new implementations of Business ID integration.
Details
Yahoo! JAPAN Business ID is no longer required when applying for Yahoo! JAPAN Ads or inviting users to your account
Previously, to use Yahoo! JAPAN Ads, a Yahoo! JAPAN Business ID was required. You will no longer need that ID.
You can apply for Yahoo! JAPAN Ads or invite users to your account using the integrated ID without a Yahoo! JAPAN Business ID.
If you only have a LINE Business ID, we encourage you to integrate your Business ID.
No need to get a Yahoo! JAPAN ID in advance
You won't need to get a Yahoo! JAPAN ID in advance when applying for Yahoo! JAPAN Ads or Yahoo! JAPAN Ads API.
Note that you must have an integrated Business ID to apply for Yahoo! JAPAN Ads.
Applications for Yahoo! JAPAN Ads and Yahoo! JAPAN Ads API
■Yahoo! JAPAN Ads
We have revised and reduced the required entry items for the application. This will ensure a smooth process.
■Yahoo! JAPAN Ads API
You can apply from the Campaign Management Tool.
Identity verification when applying
We changed the confirmation items and documents required when applying for Yahoo! JAPAN Ads, due to the integration of Business ID and the end of health insurance card issuance.
Remove Business ID integration
You can remove or modify Business ID integration from the profile screen when certain conditions are met. For details, refer to the following help page and document.
How to undo your Business ID integration
Sign in to the Payment Center
Previously, billing information (such as credit card information, adding and changing your receiving bank account) was managed through Yahoo! JAPAN Business Manager, but we are now offering a new "Payment Center" with a new management feature.
Refer to the following announcement.
Renewal of payment management and launch of Payment Center
An integrated Business ID is required for sign-in and to use the Payment Center. If you haven't integrated your Business ID, complete the process to use.
Account creation limits
Customers other than agencies can create up to 400 MCC accounts, and no maximum limit on ad accounts.
Integrated Business ID for various application forms
We are responding sequentially to sign-ins to various application forms using the integrated Business ID.
Schedules
After this implementation, we plan to implement the following around March 2026.
End of sign-in using one-time passcode
We will end sign-in to Yahoo! JAPAN Ads using one-time passcodes. We recommend that customers using the one-time passcode for sign-in integrate your Business ID as soon as possible.
Yahoo! JAPAN Business ID's sign-in using one-time passcode will become unavailable after the Business ID integration.
End of the switching feature of Campaign Editor
We will end the feature to add and switch between multiple Business IDs in the Campaign Editor.
If you have added multiple Business IDs, change your settings so that you can manage the ad account with a single business ID.

Impacts on Yahoo! JAPAN Ads API
We changed the Yahoo! JAPAN Ads API management tool access as follows.
Previous: Only companies with the relevant Business ID can retain Tool administrator and user permission to the API management tools.
After the change: If the Business ID is invited to the API management tool by your company or another company (another agency), you can retain the tool administrator and user permission in the API management tool of the inviter company. You can retain permission for multiple companies.
