The Sen no RockYou!! Ensemble Association (Secretariat: Osaka City, Osaka Prefecture | Co-representatives: Megumi Matsumoto, Yuya Ohashi) has announced that it will host 'Sen no RockYou!! 2026', a mass ensemble event where 1,000 people form a single band, on November 21, 2026. (URL: https://everybuddy.site/sennorockyou)
Sen no RockYou!! is a 1,000-person scale ensemble event that anyone can join, regardless of age, experience, or skill level.
Everyone present plays together, creating a single piece of music with 1,000 people.
The event aims to create a 'place for ensemble' where anyone can participate—whether you love music, have given it up, don't own an instrument, or can't sing.
It is not an event just for skilled musicians, nor is it divided into performers and spectators.
Background of the Event
Sen no RockYou!! started with the desire to create an 'ensemble anyone can join.'
In this event, regardless of skill or experience, everyone present makes sound.
There is absolutely no distinction between those who play and those who watch; everyone is a performer and a member of the same band.
With each iteration since the first event, the number of participants has grown, attracting people of various ages, professions, and walks of life. We began hearing voices saying things like, 'I touched an instrument for the first time in 50 years,' or 'I reunited with a friend I hadn't seen in 30 years at the event.'
A participant once told us, 'You are definitely making 500 people's lives happier.' That comment made us realize that this is not just a music event; it has become a place where someone belongs, a place they can come back to.

■ Past Themes and the Journey of Sen no RockYou!!
Sen no RockYou!! has been held with a different theme each year.
In 2023, the theme of the inaugural event was 'Fill it with Rock! ~The moment 'Awesome' becomes one~.'
Held on November 25, 2023 | Approx. 350 participants
It started with the intention to simply enjoy the day to the fullest and create a day filled with music together.
The theme for 2024 was 'Continuing Youth.'
Held on November 23, 2024 | Approx. 400 participants
We believe that dedicating yourself to something and creating with friends is the essence of youth, no matter how old you get. We poured our desire to keep youth alive regardless of age into this theme.
The theme for 2025 was 'That's LIFE.'
Held on November 22, 2024 | Approx. 500 participants
As we continued the events, we strongly realized that people who have walked various paths in life gather here from different backgrounds and lifestyles. They come carrying not only joys but also hardships and worries as they navigate their own lives. We wanted to create a moment with these people where they could feel, 'I'm glad to be alive.'
And the theme for 2026 is 'I HAVE A DREAM.'
After feeling glad to be alive, one question remained: How do we live from here on out?
To think 'I want to live like this,' one more thing was needed: a 'dream.' If you have a dream, you can move forward proudly in your life. We want to keep this place going. We want more people to see this view. We want this to remain a place where someone belongs and can return to. We chose this theme with those thoughts in mind.
Year-Round Activities
Furthermore, Sen no RockYou!! has hosted numerous practice sessions and acoustic events, with a total of over 3,000 participants layering their sounds in the same space over time.

■ Regarding the Continuation Project and Crowdfunding
Until now, Sen no RockYou!! has been organized as a corporate event.
However, with the conclusion of the 2025 event, corporate sponsorship has ended.
To sustain a 1,000-person event, a significant amount of funding is inevitably required for venue costs, audio equipment, operational expenses, and more.
To ensure this event does not end as a one-off but continues into the future, we have established the 'Sen no RockYou!! Ensemble Association'.
