YouTube accounted for more than 65% of digital video on demand hours watched in Japan in May, with 72 million viewers and 2.8 billion total hours logged on YouTube, according to new behavioral data from ampd Analytics.
The numbers come from the ampd YouTube Dashboard, a streaming intelligence tool launched by ampd Analytics, a Media Partners Asia company. Japanese viewers spent an average of 38.5 hours on the platform during the month.
“YouTube viewing in Japan is much more like TV than people realize. Long-form content dominates, audiences span all age groups, and engagement peaks at 9 p.m. YouTube isn’t competing at the edges of Japan’s screen economy, it’s operating at the heart of it,” said Sam Yousif, managing director at ampd Analytics.
The data shows a mainstream national audience, rather than a youth-skewed audience. YouTube’s reach is split almost evenly by gender, with 36.1 million male viewers and 35.5 million female viewers, and spans all age groups, from 18 million viewers ages 10-29 to 13 million viewers 60 and older. The number of viewers is biased toward the Kanto region, which accounts for 32 million people, and middle-income households, with the income range of 4 million to 8 million yen forming the largest single cohort.
News and baseball emerged as major categories. The most-watched channels overall are news outlets, led by ANNnewsCH, TBS NEWS DIG, and Nippon Television News, ahead of entertainment brand Oricon. In sports, PacificLeagueTV, PIVOT and SPOTVNOW lead in both paid and free viewers, with rights holders DAZN Japan and JRA also ranking highly in free viewers. In the entertainment field, established broadcaster channels such as Oricon, TV Asahi Official, and Netflix Japan rub shoulders with fast-growing independent creators such as Minna Minute (loosely translated, “Only 1 Minute”) and MrFuji.
This data also pushes back against the idea that short-form video has overtaken long-form content. Long-form videos accounted for approximately 70% of total watch time on YouTube in Japan, while short videos and live streams combined accounted for 30%. Viewership peaks sharply between 9pm and 10pm on both weekdays and weekends, when reach reaches 50 million, mirroring traditional prime-time television patterns.
Premium subscribers are a minority of the platform’s user base, but they show exceptional engagement. Although YouTube Premium accounts for only 15% of YouTube viewers in Japan, or 11 million viewers, these subscribers log an average of 60 hours of viewing time per month and watch about half as many videos as ad-supported users.
The ampd YouTube dashboard allows clients to drill down from a national overview to a single channel, split metrics by age, gender, income, and region, and switch views between reach, watch time, and individual titles. Filters that separate paid and ad-supported tiers separate premium viewing patterns, while cross-platform segments show overlap between YouTube viewers and services such as Netflix, Disney+, Amazon Prime Video, TVer, and U-Next. Channel-level views also reveal creator demographic profiles, top-performing videos, and monthly ranking trends.
The new dashboard resides within ampd Vision, an insights platform already used by VOD operators across the region, and leverages passive behavioral panels combined with AI-driven qualitative interviews across nine markets in Asia Pacific. In the near future, coverage will be expanded to South Korea and Southeast Asia.
