The story

A thread went up on 5ch’s Hello! Project board featuring photos of Hello! Project idol Inoue Rein’s muscular physique. Images clearly showing off her biceps and quadriceps drew a wave of astonished comments like “There’s no way you get like this without training” and “That’s athlete-level,” along with praise such as “Just make this woman a national treasure already.” Some pointed out she’d already been muscular back in her Kobushi Factory days, while others compared her build to that of fellow Hello! Project members, and the discussion branched out in all directions.

Muscles like a knockoff Gan-san (slang nickname for a famously bulky strongman)

Guess this is what happens if you do a little strength training

OG member Manakan's got a light muscular build too — Juice=Juice just trains differently

If she trained for real she could turn into a gorilla

Rei-rei's outfit has those frilly bits on the sleeves that make the armpit hard to see, but they nailed the shot anyway

Background and Discussion Points

Hello! Project idols are known for sculpting their bodies through daily dance lessons and live performances, and as with the comparisons to “Manakan” and “Ruru” raised in the thread, differences in physique between members are a frequent topic among fans. For Inoue Rein specifically, commenters noted she “was already muscular back in her Kobushi Factory days,” with many viewing her build as a reflection of years of accumulated practice. While this kind of attention to physical traits tends to take the form of praise, taken too far it can easily shade into excessive scrutiny of someone’s appearance, and the original thread did include a few posts with borderline language. In compiling this article, such excessive remarks have been excluded, with the exchange focused mainly on the praise and astonishment.
