Aniera Festa is Nagano Prefecture’s largest outdoor anime song festival, and the event has become a must-visit for fans of anisong and Japanese pop culture. Held annually at Komaba Park in Saku City, the festival blends live music, colorful visuals, and a community-focused atmosphere in the heart of Japan’s countryside.
The event is known for its vibrant key visuals, often illustrated by acclaimed Nagano-born artist Mai Yoneyama. Her artwork celebrates the spirit of anime culture while reflecting the natural beauty of the region. These large-scale visuals are a standout feature at the venue and a draw for art and design fans as much as music lovers.

Each edition of Aniera Festa brings a wide-ranging lineup of popular anisong performers, voice actors, and emerging artists. Past festivals have included big names like Aoi Shouta, angela, FLOW, and groups from the iDOLM@STER series, alongside surprise appearances and new additions announced closer to the date.
The festival’s open-air setting and enthusiastic crowd create a high-energy yet laid-back environment that’s welcoming to both longtime fans and newcomers. Tickets typically go on sale in multiple phases (including advance lotteries), with options for one-day or full weekend passes. The festival’s popularity means early application is recommended.
With its goal of making Nagano a hub for pop culture, Aniera Festa stands out for its grassroots approach, regional pride, and commitment to celebrating anime music in a meaningful, local way. For ticket details, performer announcements, and event updates, visit the official website.
