Taiwanese media UDN (United Daily News) reported on the 4th that whether it's acceptable to apply makeup on Japanese trains became a topic of debate on SNS, with netizens' opinions split.

The article stated that "the level of acceptance for rules and manners in public spaces varies from country to country," and mentioned that "whether it is acceptable for passengers to get ready or apply makeup on Japanese commuter trains is one of those topics for which many tourists have questions but no clear answer has emerged." It introduced that recently on SNS platform Threads, a female user asked, "Is it okay to put on makeup on Japanese trains? I've been wondering for years."

In response to this post, some users expressed negative opinions such as: "From a Japanese perspective, it's a breach of manners," "While not explicitly prohibited, some people feel it's bad manners," and "I think it's fine for touch-ups, but applying full makeup from scratch is a bit..."

On the other hand, many opinions suggested it is acceptable, such as: "When passing through areas like Ikebukuro, Shinjuku, and Harajuku on the Yamanote Line, I often see Japanese women touching up their makeup inside the train," "I've seen commuters applying makeup inside the train, but no one seemed to mind," "There's no clear rule prohibiting it, so if the person isn't embarrassed, isn't it fine?" and "I think it's okay to do it. However, during crowded times, there simply isn't space to apply makeup."

The article also reported that similar posts have appeared in the past on Dcard, a bulletin board for young people in Taiwan, where opinions were divided on the question, "Do you dislike people who apply makeup on public transport?" It also conveyed that on SNS in mainland China, a debate arose suggesting that applying makeup on high-speed trains should be prohibited as an "uncivilized act." (Translated/Edited by Kitada)
