“Momoiro Clover Z Invented Member Colors and Fan Names,” Claims Post — Johnny’s Fans Fire Back, 5ch Erupts in Debate

Background and Key Points

Momoiro Clover Z (“Momoiro Clover Z” / Momoclo) is a Stardust Promotion idol group formed in 2008, and the debate here sits inside a much older idol-industry practice. “Member colors” — assigning each member of a group a signature color used in merchandise, penlights, and stage costumes — is a convention that predates Momoclo by years; Hello! Project, the umbrella idol organization behind groups like Morning Musume and Berryz Kobo, was already using the system by 2004, as posters in the thread note. Likewise, fan nicknames for idol groups are a broader Japanese fandom tradition, not something any single group “invented.” “Monofu” is the fan nickname for Momoiro Clover Z supporters, while M!LK and Chou Tokkyu (Bullet Train) are Johnny’s (male idol agency) groups whose fans clashed with the original poster.

The thread never actually resolves the historical question it opens with. It splits mainly on emphasis: some posters flatly reject the “originated” claim as false, pointing to Hello! Project’s 2004-era precedent, while others concede a softer version — that Momoiro Clover Z may not have invented member colors or fan names, but popularized or pushed the practice more aggressively than earlier groups. That distinction between “invented” and “popularized” is where the real disagreement lives, even though most replies talk past each other rather than engaging it directly.

What outside readers should not take away is that this is a factual dispute with an answer being argued out — it’s an inter-fandom rivalry post (a “Monofu vs. Johnny’s-ota” flame war) using a dubious historical claim as ammunition. No poster brings up earlier, non-Hello!Project precedents either, such as Showa-era idol merchandising or AKB48’s own color/nickname conventions, which would undercut both sides equally.
