『Butterfly Effect = A very small event ultimately leads to a major outcome that was completely unforeseen.』
The mainstream bass music party that has invited numerous big names and sparked surprise and frenzy is holding a one-year anniversary celebration.

The commemorative headliner is… WOOLI, regarded as the new star and new king of the bass music scene, making his first-ever appearance in Japan!!
Mastering melodic Dubstep and Brostep, he’s collaborated with big artists like ILLENIUM and Excision. At 2026’s ULTRA MIAMI, he stepped up to headline alongside Crankdat. He’s one artist you absolutely must experience now.

Experience the new legend beginning here at Butterfly Effect’s second year!!

Butterfly Effect has booked DJs etched into heads’ hearts, from legendary artists to those at the peak of their popularity, while also spotlighting Japanese artists.

For its second year in 2026, we promise to deliver a party full of surprises and thrills, true to a bass music party at ZEROTOKYO!!

From a small culture, to a massive movement!! Kabuki Tower becomes GROUND ZERO!!
