Oshi no Ko All-Japan Project Brings Anime to All 47 Prefectures

What Is the “Children of 47 Prefectures” Campaign?

Dubbed the "Children of 47 Prefectures," the campaign re-imagines Oshi no Ko characters through the lens of local identity. Each of Japan’s 47 prefectures will be represented by a unique illustration of a character, incorporating motifs and aesthetics tied to the area's culture, landscape, or heritage. As of now, the Kansai and Kyushu region visuals are live, giving fans an early taste of what's to come.

The initiative also spans multiple platforms. A dedicated website and a launch trailer have gone live, offering a preview of the full project roll-out. Over the coming weeks, 47 short videos—each featuring newly recorded voice lines from the anime cast—will drop on Oshi no Ko’s official YouTube channel.

What Fans Can Expect at Festival Booths and Installations

Far from being a digital-only affair, the All-Japan Project will manifest physically at major regional festivals. Confirmed appearances include:

The Chayamachi Oshi Festival in Osaka
The Aomori Nebuta Festival in Aomori City
Sendai’s Tanabata Festival in Sendai

Attendees at these events can expect themed installations, exclusive previews, and pop-up shops selling limited-edition goods.

But the real draw for collectors and fans? The merch. Each prefecture will reportedly have exclusive items, including original art prints and collaboration products with local confectioners (think themed sweets and snacks that tie directly into the character designs).
