YouTube accounted for more than 65% of all digital video-on-demand hours watched in Japan in May, reaching 72 million viewers who collectively logged 2.8 billion hours on the platform, according to new behavioral data from ampd Analytics.
The figures come from the ampd YouTube dashboard, a streaming-intelligence tool launched by ampd Analytics, a Media Partners Asia company. Japanese viewers averaged 38.5 hours apiece on the platform during the month.
“Japan’s YouTube viewing looks far more like television than people assume – long-form content dominates, audiences are spread across every age group, and engagement peaks at nine in the evening. YouTube isn’t competing at the edges of the screen economy in Japan; it’s operating at its centre,” said Sam Yousif, managing director of ampd Analytics.
The data points to a mainstream, nationwide audience rather than a youth-skewed one. YouTube’s reach splits almost evenly by gender, with 36.1 million male viewers and 35.5 million female viewers, and spans every age bracket, from 18 million viewers aged 10-29 to 13 million aged 60 and over. Viewing skews toward the Kanto region, which accounts for 32 million viewers, and toward middle-income households, with the four-to-eight million yen income bands forming the largest single cohort.
News and baseball emerged as the dominant categories. The most-watched channels overall are news outlets, led by ANNnewsCH, TBS NEWS DIG and 日テレNEWS (Nippon TV News), ahead of entertainment brand oricon. In sports, PacificLeagueTV, PIVOT and SPOTVNOW lead among both paid and free audiences, with rights-holders DAZN Japan and JRA also ranking strongly among free viewers. In entertainment, established broadcaster channels such as oricon, テレビ朝日公式 (TV Asahi Official) and Netflix Japan sit alongside fast-growing independent creators including ほんの1分 (translating roughly to “Just a Minute”) and MrFuji.
The data also pushes back against the idea that short-form video has overtaken longer content. Long-form videos accounted for approximately 70% of all YouTube hours watched in Japan, against a combined 30% for Shorts and livestreams. Viewing peaks sharply between 9 p.m. and 10 p.m. on both weekdays, when reach hits 50 million, and on weekends, mirroring the prime-time patterns of traditional television.
Premium subscribers, while a minority of the platform’s user base, show outsized engagement. YouTube Premium accounts for just 15% of YouTube’s audience in Japan, or 11 million viewers, but those subscribers log an average of 60 monthly viewing hours and watch about half again as many videos as ad-supported users.
The ampd YouTube dashboard lets clients drill down from a national overview to a single channel, splitting any metric by age, gender, income and region, and switching the view between reach, hours watched and individual titles. A filter separating paid and ad-supported tiers isolates Premium viewing patterns, while cross-platform segments show overlap between YouTube audiences and services including Netflix, Disney+, Amazon Prime Video, TVer and U-Next. Channel-level views also surface a creator’s demographic profile, top-performing videos and monthly rank trends.
The new dashboard sits inside ampd Vision, an insights platform already used by VOD operators across the region, and draws on passive behavioral panels paired with AI-driven qualitative interviews spanning nine Asia Pacific markets. Coverage is set to expand to South Korea and Southeast Asia in the near future.
