INI is joining the roster for Talking Rock! FES.2026, an expanded summer festival marking three decades of the influential Japanese music magazine. The K-pop group will take the stage at Yokohama Arena on July 11 as part of the event's inaugural east-west format.

Talking Rock! FES.2026 spans four days across two locations. The Yokohama edition runs July 11–12 at Yokohama Arena and the newly added New Side Beach venue, while the Kobe edition takes place August 8–9 at the World Memorial Hall. In total, over 40 artists will perform across the festival.

INI headlines the Yokohama Arena main stage on July 11, alongside Japanese rock acts including Creep Hypnosis, Hump Back, 04 Limited Sazabys, Frederick, and My Hair is Bad. The festival also features a Live House stage with smaller venues hosting emerging artists.

Other notable additions to the lineup include Hump Back and Hammer Head Records, while Creep Hypnosis will make appearances at both the Yokohama and Kobe editions. The final artist roster was confirmed in late May, with all four days now fully booked.

Ticket pre-sales through e-Plus (available only at FamilyMart convenience stores) run through June 1. General tickets go on sale June 13 at 10 a.m. JST. Attendees can choose between center standing and assigned seating options.

Talking Rock! editor-in-chief Naohiro Yoshikawa highlighted the significance of INI's participation, noting the group graced the magazine's June anniversary issue cover. The festival represents a major milestone for the publication, expanding beyond its traditional Yokohama base to reach fans across Japan with a diverse bill mixing established acts and rising talent.
