ABEMA Anime Festival 2026 just announced its Tensura (転スラ) lineup; fans are searching now and the festival is two months out — the prime pre-event engagement window for a companion app.
ABEMA Anime Fest 2026 is confirmed for Sept 19-20, 2026 at Shibuya MIYASHITA PARK with Tensura S4, Apothecary Diaries, and Akane-banashi in the first wave; 2025 edition used numbered lottery tickets for free on-site viewing, validating the use case.'Apothecary Diaries', 'TenSura' Join ABEMA Anime Fest 2026 ↗ABEMA Anime Fes 2026 Reveals September Dates, First Lineup ↗ABEMA Anime Festival 2025 supported by Comic Cmoa ↗
Episode trackers (LiveChart.me, OtakuSync, notify.moe, Anime Sync) exist but are show-focused, not festival companions; Guidebook/Anime Expo app are generic con platforms — no AI festival companion combining lottery reminders + cast times + translation + franchise tie-ins.Anime Schedule | LiveChart.me ↗OtakuSync — Never Miss an Episode Again ↗Anime Notifier ↗Mobile App Guide for Anime Convention Success | Guidebook ↗
Core feature — lottery for free on-site viewing — gives the user no natural payment moment; anime fans are notoriously price-sensitive on utility apps and existing trackers (OtakuSync, notify.moe) are free, suggesting limited WTP beyond ad/affiliate.OtakuSync — Never Miss an Episode Again ↗Anime Notifier ↗
ABEMA Anime Fest is now a recurring 3rd-edition annual event, but the app is bound to a narrow pre-event + event-week window and a single recurring show; without expanding to other events (AnimeJapan, Comiket, Anisama) it's seasonal at best.ABEMA Anime Fes 2026 Reveals September Dates, First Lineup ↗2026 ALL Anime Event in Japan in one Calendar ↗
Straightforward to build: scraped schedules + push notifications + LLM translation layer; the harder part is maintaining accurate cast-stage times and lottery data that ABEMA itself publishes, creating a content-dependency rather than a tech risk.ABEMA Anime Festival 2025 supported by Comic Cmoa ↗
