What this is
Spread across two days at an outdoor park in Saku City, Nagano, this is one of Japan's larger regional anime song festivals, featuring two dedicated stages — the main 'Tempest Stage' and the more intimate 'Phantom Stage' where fans can watch performers up close. The lineup across both days reads like a who's-who of anime music: GRANRODEO, angela, Eir Aoi, FLOW, i☆Ris, Lia, ZAQ, and many more, plus franchise-linked acts from Umamusume: Pretty Derby and Aikatsu Stars!. An open-call talent project called 'ANIERA New Face 2026' runs alongside the main event, giving it a community dimension beyond the headline performances.
Who should go
Anime music fans who follow voice actors and anisong artists will find the two-day lineup genuinely strong. The outdoor park setting and multi-stage format suits groups and dedicated solo attendees equally — this is not a casual drop-in event.
Good to know
Tickets are handled via advance application — check the official site for the ticketing platform (likely eplus.jp or pia.jp), both of which accept foreign credit cards; convenience store pickup at Lawson is the most reliable collection method for visitors without a Japanese delivery address. Komaba Park is an outdoor venue, so there is no fixed seating capacity in the traditional sense — bring a portable seat or blanket if floor seating is permitted in designated areas. Cash is advisable for food stalls and merchandise booths at outdoor festivals in Japan, as card acceptance at vendor stands is inconsistent. Arrive well before doors open on each day to secure a good position, especially for the Phantom Stage where capacity will be more limited. Foreign visitors should note that most MC interactions and announcements will be in Japanese only.
