January 23: ABEMA Opens Yahoo Ads Instream, CTV Reach Expands
ABEMA will start serving Yahoo Ads instream placements across PC, mobile, and Connected TV advertising in Japan as early as January 28. This move, under the LINE Yahoo partnership, gives marketers scale in premium video with viewable impressions counted at playback start. From February, access will expand beyond managed accounts. For investors, this signals growing CTV demand, new budget flows into streaming, and stronger yield potential for high-quality inventory. We explain what changes, why it matters, and how to plan buys.
What the rollout means for advertisers
Yahoo Ads instream video will run on ABEMA across devices, with delivery planned to begin as early as January 28. Managed accounts can start first, followed by broader access from February, according to the announcement reported by Web担当者Forum on Yahoo News Japan source. Advertisers can reach users consuming long-form and live content, improving video completion potential versus open web placements.
The format counts a viewable impression at the start of playback, which aligns with how many premium video partners measure. This helps simplify reporting and benchmarking across platforms. Buyers should still compare completion rate, audible rate, and attention metrics to ensure quality. Transparency on placement and frequency will matter as buys scale across screens.
Why CTV demand in Japan is rising
CTV extends digital targeting into the living room, while PC and mobile add frequency and incremental reach. For brands, the ability to appear in a lean-back environment during news, sports, and entertainment can lift recall. Pairing Yahoo Ads instream with existing video plans can improve budget efficiency and reduce overlap across channels.
Streaming services offer controlled content libraries and predictable ad experiences. ABEMA’s premium context helps brands reduce risks associated with user-generated content. Combined with platform-level controls and third-party verification tools, advertisers can manage adjacency, apply exclusion lists, and maintain consistency in creative specs across TV screens and personal devices.
How to plan buys and measure impact
Start with managed service if you need guidance, then shift to self-serve as access broadens in February. Test ABEMA inventory via Yahoo Ads instream alongside existing video lines to find incremental reach. Align dayparting with viewing peaks on connected TV. Use creative cutdowns optimized for silent start and clear branding in the first seconds.
Track cost per completed view, view-through rate, and unique reach across devices. Since viewable impressions start at playback, compare attention signals and completion against other premium publishers. Include brand lift or search lift studies for awareness goals. ABEMA can also support test-and-learn on frequency caps to reduce waste across TV and mobile.
Investor lens: revenue mix and competition
More premium video supply can improve fill rates and broaden advertiser categories. For ABEMA, diversified demand through Yahoo Ads instream may support steadier CPMs versus relying on direct deals alone. As campaigns ramp, watch for improvements in sell-through during prime events, plus use of first-party signals to improve targeting efficiency.
Under the LINE Yahoo partnership, combining scaled demand with premium streaming inventory strengthens the local ad stack. Competition remains active across TVer, global platforms, and retail media video. The key edge will be quality supply, transparent reporting, and flexible buying methods that meet brand and performance needs in Japan.
Final Thoughts
This integration adds real reach and control for Japanese advertisers. ABEMA gains broader demand pipes, and buyers get premium video at scale across PC, mobile, and connected TV. Start with small tests in late January, then expand budgets as February self-serve access opens. Compare cost per completed view, completion rate, and brand lift against other premium channels. Keep frequency caps tight across screens, and refresh creatives for silent autoplay. For investors, the shift points to growing CTV ad budgets in Japan and stronger monetization for high-quality streaming environments supported by major ad platforms.
FAQs
When will Yahoo Ads instream start delivering on ABEMA?
Delivery could begin as early as January 28, with managed accounts first. From February, access is expected to broaden beyond managed service, allowing more advertisers to activate campaigns. Plan tests in late January, validate reporting, then scale budgets as inventory and targeting options expand.
How are viewable impressions counted for this format?
A viewable impression is counted at the start of playback. Advertisers should still track completion rate, audible rate, and attention metrics to verify quality.

What are the advantages of Connected TV advertising here?
CTV places brand video in a lean-back setting on the biggest screen in the home. It can deliver higher recall and stronger completion versus some mobile placements. Cross-screen buying adds incremental reach, while premium streaming environments reduce risk and support more predictable ad experiences.
How should marketers test and scale budgets?
Begin with a controlled test across PC, mobile, and CTV, using consistent creative and clear KPIs. Monitor cost per completed view and unique reach. If performance holds, scale budgets and add brand lift studies. Refresh creatives regularly and tighten frequency caps to reduce duplication across screens.
