Pre-Roll Video is bought on CPM only, averaging $20.25. TikTok Ads is bought on CPM only, averaging $12.15. Analysis for Japan in 2026.
Japan is Asia's largest mature digital ad market and one of the most expensive globally — CPMs run roughly 35% above US baselines. It is also structurally different from Western markets in ways that catch newcomers out repeatedly. Yahoo! Japan retains meaningful search share alongside Google. LINE is the dominant messaging platform and a serious ad channel, not a niche play. Display ad creative norms favor higher information density and louder visual treatments than Western markets. Japanese-language creative is non-negotiable — direct English translations consistently fail. Mobile-first behavior is universal, and the Japanese commerce funnel typically involves longer consideration phases and more comparison-shopping touchpoints than US equivalents. APPI (Act on Protection of Personal Information) governs privacy and was amended significantly in 2022.
Video ads that play before online content
Short-form video advertising on TikTok
The auction, the creative, the budget floor — the three things you actually need to know before picking a platform.
Pre-roll (the video ad before online video content, non-YouTube) is CPM-priced at $12–20, sold through DSPs against a video inventory pool separate from social. Skippable and non-skippable formats coexist; non-skippable commands a 20–30% CPM premium.
15s (most common), 6s bumper, or 30s. 1920×1080 16:9, 24 or 30fps, H.264. Captions and audio-off usability increasingly required as autoplay-muted becomes default.
$3K–5K/month for standalone pre-roll; often bundled with programmatic display or OTT in a single video-inclusive DSP buy.
TikTok Ads runs on CPM ($8–12 typical, higher for premium placements like TopView). CPC is available but the platform's optimization heavily favors CPM-bid campaigns. Auction density is lower than Meta but growing quickly; creative quality dominates.
9:16 vertical video (1080×1920), 9-60s (best performance 15-30s), native-feeling — polished ads underperform UGC-style creative here by 2-3x. Sound-on is standard. Captions optional but boost completion.
$500/day ($15K/month) is the practical floor for the Traffic and Conversion objectives to exit learning phase in a reasonable window. Smaller budgets work for Awareness and Video View goals.
