Renamed from Yahoo! JAPAN Display Ads in September 2026, following LY Corporation’s rebrand of Yahoo! JAPAN Ads to LY Ads. Only the display name and icon changed — existing connections, data sources, and widgets are unaffected.
LY Ads Display Ads (formerly Yahoo! JAPAN Display Ads) is the display product of LY Ads, the advertising platform operated by LY Corporation, serving image, video, and responsive display creative across Yahoo! JAPAN properties and partner sites. Connecting it brings ad accounts, campaigns, ad groups, and ads into Adriel dashboards alongside daily performance, video and viewability metrics, and the image and video creatives themselves.

​
Before you connect

The following are required:
  • A Yahoo! Japan Business account with access to LY Ads.
  • An LY Ads Display Ads account with API access enabled.
  • Manager account access, where the ad account is mediated through an agency.
This connector covers the Japanese market only and is distinct from Yahoo (US/global) display advertising, which is a separate platform with a separate API. LY Ads Display Ads and LY Ads Search Ads share a single Biz-OAuth authorization but are configured as separate data sources.

​
Connect LY Ads Display Ads

1

Select the data source

On the Data Sources page, search for LY Ads Display Ads and select it.
2

Authorize through Yahoo Biz-OAuth

Click Connect to be redirected to Yahoo! Japan’s Biz-OAuth screen. Sign in with Yahoo! Japan Business credentials and approve the requested yahooads scope.
3

Select the ad account

Choose the ad account to ingest from the list of accounts visible to the authorized user. Select the parent manager account first if access is mediated through an agency.
4

Save the connection

Click Save to begin the connection. The initial sync of historical performance and creative assets runs in the background.

​
What gets imported

The connector imports the full campaign hierarchy (ad account → campaign → ad group → ad) and daily performance metrics. Display-specific coverage includes video performance, viewability, and conversion-category metrics, plus image and video creatives downloaded during the sync so creatives appear alongside their metrics. Available breakdowns include device, age, gender, region, location, and site (campaign and ad-set level only). For the complete list of metrics, breakdowns, and limits, see the LY Ads Display Ads data reference.

​
Troubleshooting

The LY Ads Display Ads API does not expose country-level geographic reports for display campaigns. Use the region or location breakdown for sub-Japan geographic insight instead.
Site (publisher) breakdown is supported at campaign and ad-set level only. Requesting it at ad level is rejected by the LY Ads API with INVALID_DIMENSIONS_METRICS_COMBINATION. Move the breakdown up to ad-set or campaign level.
Impression share, search rank lost, and budget lost are search-specific fields and are not available on display. For search performance, connect the LY Ads Search Ads data source separately.
