Hiroko Moriguchi Troubled by Rude Passenger on Flight — Warned Him, But “He Started Again”

Background and Key Points

For readers unfamiliar with her, Hiroko Moriguchi, 58, is a veteran singer-tarento who debuted in 1987 and became a fixture of the anime-theme-song era, best known abroad (if at all) for the Mobile Suit Zeta Gundam ending theme and the Formula 91 theme song, alongside a long-running late-night radio show and six appearances on NHK’s New Year’s Eve Kohaku Uta Gassen. She’s also a graduate of Horikoshi Gakuen, the Tokyo high school famous for training idols and actors. The flight in question landed at New Chitose Airport, the main gateway to Sapporo and Hokkaido, and the meal she missed, Jingisukan, is a grilled-mutton dish strongly associated with that region, which is why losing dinner plans mattered enough to mention.

The thread didn’t split over whether the passenger behind her was rude; it split over whether a celebrity should use X (Twitter) to publicly flag an anonymous stranger’s bad manners at all. One camp argued it’s free venting that adds nothing and just makes her look prickly; another argued that when someone with a large platform calls out a common but under-policed annoyance, it can nudge public manners overall, precisely because bystanders rarely say anything in the moment.

What outside readers may miss is the social weight of her having spoken to the man directly at all: openly confronting a stranger’s behavior face-to-face is unusual in Japanese public etiquette, which normally favors silent tolerance or a quiet word to airline staff rather than direct pushback, let alone airing it afterward online. That’s the real subtext posters argued around without ever stating it outright.
