More Than 100 Idol Acts Are Heading to Ueno for Four Days of Giga Mori MAX Live

Article

Ueno Park is usually known for museums, the zoo, and cherry blossoms. For four days in October, it's also hosting more than 100 idol acts.

Dates, Venue, and Scale

Giga Mori MAX Live runs October 9-12, 2026, across Ueno Park's Outdoor Stage and Ueno Park Suijo Ongakudo, organized by Good Choice Entertainment. The organizer's own press release describes more than 100 idol and artist appearances across the four days — a scale that puts many independent and agency groups on the same bill rather than one agency's own lineup.

Highlighted Acts

Confirmed highlighted acts include Rain Tree, @onefive, Tokyo CuteCute, Red Radiance, Up Up Girls (Kakko Kari), Kamen Joshi, Junjo no Afilia, and Finally. Both @onefive and Rain Tree's own official schedules confirm an October 11 appearance at the event.

How It Compares

The organizer's previous Golden Week edition, Mega Mori MAX Live, reportedly featured more than 140 appearances across five days — giving a sense of how large this organizer's festivals have grown. A full lineup for every day of Giga Mori MAX Live hasn't been published in full detail; this article covers what's officially confirmed rather than a guessed complete schedule.

Fan Perspective

For idol fans, multi-day, multi-group festivals like this are a chance to see acts they'd otherwise have to catch on completely separate nights, all within walking distance in one park.

What To Know

This isn't a single-agency showcase — it brings a large number of independent and agency idol groups into one long, multi-day Ueno event, giving fans a rare chance to catch many different groups without traveling between separate shows.

Ueno Park is better known internationally for its museums, zoo, and cherry blossoms; a large open-air idol festival taking over the same park shows a very different, fan-culture side of contemporary Tokyo.
