Measles Case at Takarazuka Theater and JR Keiyo Line Sparks Public Outrage

It has been revealed that a man in his 30s who attended a performance at the Tokyo Takarazuka Theater was infected with measles. As he also used the JR Keiyo Line for travel between Shin-Narashino and Tokyo, strong concerns and criticisms are mounting on social media regarding the potential for widespread infection among the general public.

According to the Yomiuri Shimbun and other sources, the infected man attended a performance at the Tokyo Takarazuka Theater on the 20th of this month, potentially coming into contact with many audience members. It is reported that the man went out despite experiencing symptoms like fever, leading to harsh comments on social media such as "What he did is no different from terrorism" and "A new form of bioterrorism." Furthermore, as some Takarazuka Revue performances include scenes where performers descend into the audience ("kyakuseki-ori"), concerns were also raised for the performers, with comments like "What if he infected the Takarasiennes (Takarazuka performers)?"

It was also discovered that the man used the JR Keiyo Line (between Shin-Narashino and Tokyo), raising fears about the impact on commuters and students who used the train at the same time, as well as participants in other events held along the line (such as SKE photoshoots and the Blue Archive Fes). Some users expressed anxiety, saying, "It chilled me because it was within my usual range of activity."

Measles is an extremely contagious disease, even transmissible through airborne particles, and carries a high risk of severe complications for pregnant women, newborns, and individuals with weakened immune systems. The incubation period is said to be 10 to 12 days, leading to concerns about specific groups, with comments like "It would be a disaster if the infection spread among unvaccinated students preparing for exams."

In response to this situation, social media users are once again emphasizing the need for improved personal infection control and public conduct, with comments such as "If you're feeling unwell, please stay home" and "Indulging in what you want to see without self-management is virtually bioterrorism." For those who used the theater or the Keiyo Line during the same period and develop symptoms suggestive of measles, such as fever or rash, it is strongly advised to contact the nearest public health center by phone before seeking medical attention.

The context

The incident described in the article has sparked significant public concern in Japan due to several factors.

Firstly, the Takarazuka Revue is a highly popular and prestigious all-female musical theater troupe in Japan, known for its elaborate productions and devoted fanbase. The Tokyo Takarazuka Theater is one of its primary venues. The concern mentioned about "Takarasiens" (or "Jennu" as they are affectionately called) infecting performers stems from the fact that some Takarazuka shows feature "audience interaction" scenes (客席降り - kyakuseki-ori), where performers walk through the aisles, potentially coming into close contact with audience members. This intimate aspect of the performances makes the potential for infection particularly alarming to fans and the public.

Secondly, the JR Keiyo Line is a major commuter railway line connecting Chiba Prefecture, including areas like Shin-Narashino, to central Tokyo. It is heavily used by daily commuters, students, and also by visitors to popular destinations such as Tokyo Disney Resort. The mention of other events like "SKE photoshoots" and "Blue Archive Fes" along the line highlights the potential for large gatherings and increased exposure risks, amplifying fears of widespread transmission among diverse groups of people.

Lastly, measles (はしか - hashika) is a highly contagious viral disease that can lead to severe complications, especially in vulnerable populations. While Japan has generally high vaccination rates, public health authorities remain vigilant about outbreaks. The strong public reaction, including terms like "bioterrorism," reflects deep anger and frustration over perceived irresponsible behavior by an individual who went out while symptomatic with such a dangerous and easily transmissible disease. The specific concern for "unvaccinated students preparing for exams" points to a demographic that might be particularly vulnerable due to stress-compromised immunity or potential gaps in vaccination records, and who spend time in concentrated environments like schools or cram schools.
