As an additional part of the “Grateful Yesterdays Tour 2026,” an Asian tour has been announced, with dates in Taipei, Seoul, and Hong Kong!
This will be back number 's first overseas performance.
-----------------------------------------------------------
"Asian Tour!!"
Or
"We're performing live overseas!!!"
When someone says something like that, it makes me tense up.
Ambition, band image, etc.
I feel like I'm about to start talking about something complicated.
"It seems there's someone waiting for you."
When you say
Oh really? Then I have to go!
That's what happens.
Still a little
Really?
Are there enough people here to hold a live performance?
Just kidding!
Sometimes I think so, sometimes I don't.
Feeling excited and thrilled
But before that, there's a big job to do domestically.
That's how I'm living my life.
I would be happy to meet you somewhere.
Even if we can't meet
Sometimes they remember me
I'm happy just knowing that you're listening to my music.
Iyori Shimizu

When I think about taking on a challenge, I automatically imagine "having everything I've built up over 20 years and all the time I've invested," but if I step on the scale, I realize I don't have that much to offer. Well, maybe a little bit, but still.
Even if you let go of everything and step onto the stage with a blank mind, believe that those things "reside" within you.

I'm happy to be able to challenge myself with something new after playing in a band for over 20 years.
We're not the type to adapt to a large venue or do things differently, so we might just have to focus on our music as usual. But we'll practice hard and be ready for the day so that everyone who comes will feel glad they got to see back number here.
I hope to see you at the live venue!
islet Kazuya
I quite enjoy watching soccer matches.
Watching the players run freely across that vast field, creating all sorts of drama, and not knowing what will happen until the final whistle—that's when my heart gets really excited.
I'm so excited to be able to perform a live show in such a wonderful place!
And it's a stadium tour visiting 5 venues!!!
I guess I should start with running drills?
No, more importantly, I need to practice my drumming!
It's not on the pitch, but on the stage, but from the very first note to the very last note that has finished ringing out, both you who came to the venue and myself
I'll put my heart and soul into every single hit to deliver a live performance that will make your heart race! I'll give it my all!
Woohoo! Let's do it!!!
