I live in Japan, so I had no trouble finding concert tickets.
[PIA ARENA MM]: This venue specializes in music performances, so the seating is generally decent.
This venue has a capacity of about 15,000, and all seats, including standing room, were sold out.

My seat felt relatively close to the stage.
I arrived 15 minutes before the show started.
In Japan, taking photos or videos inside concert halls is basically prohibited.
So everyone at the concert just cheered only enthusiastically.
Yunah: She sang a song by [Aimyon].
Iroha: She sang [E-girl]'s song [Dance with me now]. And she danced.
Wonhee: She sang [Aya Matsuura]'s song and danced.
And during the concert, [Noa] made a surprise appearance and sang a song.
[ILLIT]: They also sang a bit of their Japanese debut song, scheduled for release on September 1st. It featured a kitschy rhythm and choreography, seemingly designed for a video challenge.
They also revealed the choreography for [oops!] for the first time.
They also sang [TWICE]'s song [What is love].
Encore: [Almond Chocolate] + [I'LL LIKE YOU] + [IYKYK]
From this point on, taking photo was permitted.
They came right up to my seat.
So I shook the [bottle of soda] I was drinking from.
And Yunah smiled at me.
She was very pretty.
And Minju was very pretty, too.
The audience response at the concert was very enthusiastic.
The gender ratio of the audience was roughly 50:50.
Parents with their daughters, couples, and middle-aged couples were also frequently seen.
Perhaps because there were many male fans, their cheering was loud.
[ILLIT] performed the concert in Japanese for over 90% of the time.
The two-hour concert felt very short.
This was likely due to the lack of singing and the lengthy talk show.
