Re: #5
Guess she's really into "Sao" (pole)?
9AnonymousSep 22, 2026 16:39
Because one member got kicked out, that's why.

Ishii — 03, could've gone with "Lesser" (as in red panda) too, no?
15AnonymousSep 22, 2026 16:41
Tamio Okuda used 082, Hiroshima's area code, right.

Yesterday I got a few comments asking why I picked No. 3, so…
it's for Mimi-chan's 3!! 🐈💜

I had a lot of numbers I liked, so I agonized over it, but
in the end I thought, "It's gotta be my beloved Mimi-chan's" lol

3 was already one of my favorite numbers to begin with, so
I figured, why not! and settled on No. 3!

What number would you all pick? ☺

Maria Makino wore Shinjo's No. 1 at one point, and Nakata Sho's No. 6 at another.
28AnonymousSep 22, 2026 16:47
Thanks to Makino graduating, I got to do this job.
Managed to squeeze it in right at the tail end of this season.
Good, good.

Wondered what "Hachamaru" was — turns out it's the mascot character of Hasami Town.

Looks like Marin Fukuda also had "8" gradually come to her.
33AnonymousSep 22, 2026 16:49
What about 833 (read as "ha-sa-mi") for Hasami? No good?
36AnonymousSep 22, 2026 16:50
Marin's 8 is for Shiori Yagi's 8.

It does say "other than me," just to be safe.

Re: #57
Never once thought of them as comrades.
58AnonymousSep 22, 2026 17:17
Didn't this blow up online over the numbers, like it did for ME:I?
59AnonymousSep 22, 2026 17:20
Could've been a heartwarming story about headcount, but they had to go and complicate it — what a bungle.
62AnonymousSep 22, 2026 17:22
While we're at it, can someone list out ROSY's Lotte uniform numbers from the other day too?

Background and Talking Points

In Hello! Project in recent years, it’s become a tradition for each group’s project to unveil a “uniform number” for every member. Many pick numbers tied to their birthday or inherited from an admired senior or fellow member, and Yasumi Tanimoto explained on her blog that she chose hers based on what felt like “a number that means something to Tsubaki [Factory].” Rather than splitting into opposing camps, the thread was mostly casual chatter, with users trading the backstories behind other members’ numbers — birthdays, numbers borrowed from a favorite senpai, digits tied to a qualification or nickname — with almost no criticism in sight. That said, a similar uniform-number project for another group previously stirred controversy over headcount and how numbers were assigned, and a few posts referenced that history. Exchanges like these, digging into the meaning behind the numbers, also give fans a chance to deepen their understanding of the members they support.
