Oshi no Ko Season 4 Is the Final Season: New Teaser Visual, Trailer, and What Collectors Should Watch
Oshi no Ko is heading for its finale. Studio Doga Kobo's idol-industry thriller has confirmed that its upcoming fourth season is the final season, and a fresh teaser visual and trailer were unveiled at the Ichigo Production☆Fan Thanksgiving 2026 event on August 16, 2026. For a series that has topped seasonal fan polls since its debut, the announcement that the story is entering its last act is a big moment — and a signal to collectors that demand for its figures is about to climb.
What Was Announced
Season 4 was first revealed on March 25, 2026, right after Season 3's finale aired, and it was branded the final season from the start. The August event followed up with a teaser visual and a trailer that put the spotlight back on the Hoshino siblings as their story approaches its conclusion. Doga Kobo, which animated all three previous seasons, returns to finish what it started, with Daisuke Hiramaki again directing. No premiere date has been set; because past seasons landed roughly a year and a half apart, coverage widely expects the finale no earlier than 2027, though that remains speculation until the production confirms it.
Why This Finale Matters
Unlike many long-running adaptations, this one has a fixed destination. Aka Akasaka's manga, illustrated by Mengo Yokoyari, finished its four-year run in Weekly Young Jump in November 2024 at 166 chapters, so the anime team knows exactly where the story ends. That makes the final season a rare thing in anime: an adaptation with a complete, author-approved conclusion to work toward rather than an open-ended pause. The returning cast — Takeo Ōtsuka as Aquamarine, Yurie Igoma as Ruby, Megumi Han as Kana Arima, and Rie Takahashi as Ai Hoshino — anchors a show that swept its seasonal polls and, most recently, was voted a standout of the Winter 2026 lineup.
What It Means for Collectors
Final seasons tend to concentrate a franchise's collectible energy. Oshi no Ko already has a deep bench of characters that translate beautifully into figures — Ai Hoshino in her idol stage look, Ruby and Aqua, Kana Arima, MEM-cho and Akane — and prize lines and scale figures tend to see renewed interest whenever a series returns to screens or reaches a milestone. If you have been eyeing a particular character, the window before a final season airs is usually the calmest one: attention (and resale pressure) climbs as the premiere nears. Idol-drama fans also tend to overlap with other character-forward hits, so a display built around Oshi no Ko sits comfortably next to figures from other Doga Kobo and Shueisha favorites.
Building an Oshi no Ko Shelf at Akibato
Akibato doesn't have a dedicated Oshi no Ko collection yet, but the characters that suit this series best — idol-style scale figures and character prize figures — live in two places worth browsing. Start with Akibato's Figures collection for scale and prize figures across popular franchises, and check Akibato's Ichiban Kuji collection for lottery-prize figures, acrylic stands, and small display pieces that idol-series fans love. A handy note for international collectors: Akibato charges shipping by total parcel weight rather than per item, so a few small prize figures or acrylic stands can travel together for roughly the cost of sending one — an easy way to round out a display without paying extra postage each time.
