Spring Music Festival in Eastern Japan [2025]

It’s a circuit event dedicated to idols, split into daytime and nighttime sessions, with the night session running all night long. You can see a wide range of groups, from idols active on the front lines to those on the verge of breaking out.

This is a live event hosted by J-WAVE that features an impressively star-studded lineup of artists. It seems there will also be childcare facilities at the venue, so parents with small children can attend with peace of mind—what a nice touch!

Held under the concept of “Encounters and Inspiration that Connect to the Future,” this event uses green electricity—that is, power generated with low environmental impact from sources like wind, solar, and biomass. Hosting it with sustainable energy is a wonderful initiative that aligns perfectly with the concept.

Earth Day has been held as a global festival in 175 countries, promoting a zero-waste approach while inviting everyone to think together about the planet’s future. Since 2001, Earth Day Tokyo has taken place in Yoyogi Park, with the aim of creating a space where people can reflect on what they can do for the Earth through live music, talk shows, and shopping, while fostering mutual respect. It’s a family-friendly festival featuring not only music but also a wide variety of food vendors and shops closely connected to everyday living.
