World Happiness, the eclectic Japanese music festival known locally as "Wa-hapi," is making its much-anticipated return after nearly a decade away. The event will take place on June 28, 2026, at Tokyo's iconic Yoyogi National Stadium First Gymnasium.

The festival's subtitle "I'm HOME" feels particularly fitting given the long absence. World Happiness was known for bringing together an incredibly diverse lineup that perfectly captured the spirit of Japanese music culture, from veteran artists to emerging acts across multiple genres.

While the full lineup hasn't been announced yet, the festival's return promises to reunite familiar faces with longtime fans. Haruomi Hosono, the legendary musician and Yellow Magic Orchestra member, has been confirmed as one of the returning performers. Tokyo Ska Paradise Orchestra (Skapara), the influential ska band that helped define Japan's ska revival scene, will also take the stage.

For international J-Pop fans who might not be familiar with World Happiness, the festival has historically been celebrated for its unique ability to showcase Japan's musical diversity. Previous editions featured everything from idol groups and rock bands to electronic artists and traditional folk musicians, creating an atmosphere that felt like a true celebration of Japanese music culture.

The nine-year gap makes this comeback particularly significant. The Japanese music scene has evolved dramatically since the festival's last iteration, with new genres emerging and established artists exploring different sounds. This return offers a chance to see how World Happiness will adapt to reflect the current landscape while maintaining the inclusive spirit that made it special.

Ticket information and additional lineup announcements are expected in the coming months.
