What is "SOZOW Fes"?

"SOZOW Fes" is an experience-based edutainment event that fuses play and learning. It started in 2019 (initially "Go SOZO") in areas like Roppongi and Ikebukuro, and was also held online with TV Asahi during the pandemic. Real-scale events resumed in earnest from 2025, and to date, over 20,000 families and more than 100,000 parents and children have participated.

As a "place to expand children's curiosity and future possibilities," we provide opportunities nationwide for children to challenge creative experiences utilizing various technologies, driven by their curiosity.

This Yamaguchi event will deliver three days perfect for summer vacation free research and memory-making, as a "digital festival."

Highlights of This Event

"Curiosity License," a First for SOZOW Fes

This SOZOW Fes is not just about experiencing and finishing. We are introducing a new mechanism for the first time as SOZOW Fes, to connect a day's experience to the child's own "discovery of curiosity."

Curiosity Passport: Distributed to each visitor upon entry. While visiting booths of interest, children will record "what was fun" and "moments that moved their hearts."

Issuance of Curiosity License: When experiences are reviewed and entered into a dedicated app, AI will issue a "Curiosity License" with a "future title" unique to the child. They can take home this one-of-a-kind license.

And, at the conclusion of all experiences, a special finale exclusive to the day will be prepared. Please enjoy the moving moment when the entire venue becomes one at the venue.

This is a new initiative unique to SOZOW, which advocates "Unleashing Curiosity," connecting "experience" to "discovery of curiosity."

Collaboration Booths with Local Yamaguchi Companies, Only Available Here

Collaboration with local Yamaguchi companies is also a unique highlight this time. Content that can only be experienced in Yamaguchi will be gathered, such as "Future Super!? Personality Explosion! Building Competition for Everyone" (Minecraft) presented by Marukyu Corporation, "Challenge Automatic Driving!? Aim for Prizes with Robot Shooting" presented by Yamaguchi Mazda Co., Ltd., and "Take Photos as a Conductor!? Transform! Dream YouTuber Experience" with special cooperation from JR West.
