New Festival "HERO SONIC 2026" Produced by Hiroyuki to be Held! Two Days at Yokohama Red Brick Park

Comment from Overall Producer Hiroyuki

"They're apparently doing something."

The new culture festival "UP-T presents HERO SONIC 2026" will be held for two days on June 27 (Sat) and 28 (Sun), 2026, at Yokohama Red Brick Park in Yokohama City, Kanagawa Prefecture.

With "Hiroyuki (Hiroyuki Nishimura)," known as a businessman and debater, serving as the overall producer, it will be developed as a "next-generation large-scale festival" that blends Japan's pride in idol culture with internet culture, food, and social contribution.

At the venue, live performances by a wide range of idols, from popular groups to emerging artists, are planned across multiple stages.

On the talk stage (free area), where Hiroyuki is scheduled to appear, special talk sessions of "Hiroyuki x Idols" that can only be seen at this event will also be held.

Furthermore, in collaboration with online media, the event aims to be enjoyed from both real and online perspectives, with coverage of the venue and project activities through articles and broadcasts.

A food area with kitchen cars will also be set up within the venue, developing the festival as a place where one can enjoy "food" alongside live performances.

Various companies are also expected to have areas with exhibits and experience-based content, offering diverse projects.

Moreover, "SDGs" and "social contribution" are highlighted as important themes for this event.

In collaboration with the title sponsor UP-T, a project is planned to collect used clothing such as T-shirts at the venue, and to reuse or donate the collected clothing.

The aim is to create a system where attendees' participation in the event itself contributes to social good.

"HERO SONIC 2026," which fuses idols, the internet, food, and social contribution, is expected to attract attention as a festival that presents new possibilities for Japanese culture.

Details such as performers and ticket information will be announced sequentially.
