Anime "[Oshi No Ko]" viewership ranking by prefecture announced! Nagano takes the top spot over Toyama and Aomori

ABEMA has announced the ranking of prefectures with the highest average viewership per person for the anime series "[Oshi No Ko]" between January and March 2026.

This ranking covers the period from January 1 to March 10, 2026, and was calculated by independently aggregating total views from real-time and on-demand streaming across the entire series.

The top five prefectures are as follows:

▼ "[Oshi No Ko]" Average viewership per person by prefecture (January – March 2026)

1st Place: Nagano Prefecture
2nd Place: Toyama Prefecture
3rd Place: Aomori Prefecture
4th Place: Niigata Prefecture
5th Place: Iwate Prefecture

Nagano Prefecture was the region where the series was viewed most per person. Among the top five prefectures, some regions are observed to have a discrepancy in the broadcast date and time of the latest episodes, often due to a limited number of commercial television stations.

"[Oshi No Ko]" is based on the manga serialized in "Weekly Young Jump" by Aka Akasaka (Original Story) and Mengo Yokoyari (Illustration), with the worldwide series circulation exceeding 25 million copies (including digital). The TV anime premiered its first season in April 2023, its second in July 2024, and the third season began streaming in January 2026.

The third season was streamed at the fastest rate, simultaneous with its terrestrial broadcast. During the streaming period, all episodes from the first season through the latest episode of the third season were available for viewing.
