by As anime continues to grow globally, how and when viewers watch new episodes has become an important topic. One major issue in Japan is the delay in terrestrial TV anime broadcasts across different regions.
A recent analysis by ABEMA, a leading streaming platform, sheds light on this issue using viewership data from the popular anime Oshi no Ko.
ABEMA Data: Which Regions Watch the Most?
ABEMA analyzed viewing data for Oshi no Ko across all seasons from January 1 to March 10, 2026, focusing on average viewership per person by prefecture.
Top 5 Prefectures by Viewership:
- Nagano Prefecture
- Toyama Prefecture
- Aomori Prefecture
- Niigata Prefecture
- Iwate Prefecture
Interestingly, no major Tokyo metropolitan areas appeared in the top rankings.
Why Are Regional Areas Watching More?
The key reason lies in broadcast timing differences.
How Broadcast Delays Work
In Japan:
- Major stations like TOKYO MX and BS11 often air anime earlier
- Local or regional stations may broadcast the same episode hours later
In the top-ranked prefectures:
- There are fewer commercial TV stations
- Episodes are often delayed until around 1:00 AM or later
This delay pushes viewers toward streaming platforms like ABEMA, where episodes are available earlier or simultaneously.
Role of Streaming Platforms Like ABEMA
ABEMA has strategically positioned itself to solve this problem.
Key Features:
- Simultaneous streaming with terrestrial broadcasts
- Free access during the streaming window
- Availability nationwide, regardless of local TV schedules
For Oshi no Ko:
- New episodes stream every Wednesday at 11:00 PM (JST)
- All episodes—from Season 1 to the latest—are available for free (limited time)
This makes streaming the fastest and most convenient option, especially in regions with delayed TV broadcasts.
Is There a Direct Link Between Delay and Streaming Popularity?
Surprisingly, the answer is not entirely.
For example:
- Yamanashi Prefecture had one of the latest broadcast times (around 2:30 AM / 26:30)
- However, it did not rank in the top viewership list
Why?
Several factors influence viewing behavior:
- Access to BS channels (like BS11), which broadcast earlier
- Increased use of on-demand streaming platforms
- Individual viewer habits and preferences
This shows that while delays matter, they are not the only factor driving streaming popularity.
Broadcast Schedule Differences (Simplified Overview)
Anime broadcast times vary widely across Japan. Here’s a simplified breakdown:
Early Broadcast (Same-Day Priority)
- TOKYO MX: 23:00
- Sun TV / KBS Kyoto: Around 24:00
Standard Late-Night Broadcast
- Many regional stations: 24:00 – 25:30
Delayed Broadcast Regions
- Some areas: Up to 26:30 (2:30 AM)
Satellite Broadcast
- BS11: Around 25:00 (nationwide availability)
This variation creates a fragmented viewing experience, especially for fans trying to avoid spoilers.
