A devastating sexual assault scandal has erupted in Japan’s idol industry as 19-year-old Shuna Amamiya from the newly-formed girl group Pretty Chuu has accused Taichi Saito, the longtime boyfriend of her producer Yurinya, of rape and impregnation. The explosive teenage idol allegedly raped allegations, which surfaced on August 1, 2025, have sent shockwaves through the Japanese entertainment world and sparked widespread outrage among fans demanding justice for the teenage victim.
The disturbing case came to light through leaked audio recordings and testimony shared by popular YouTuber Korekore, revealing a pattern of sexual abuse that allegedly began when Saito secretly filmed the unconscious teenager at Yurinya’s home. According to reports, Saito subsequently raped and impregnated Amamiya while she was sleeping, leading to threats and attempts at financial coercion to silence the victim.
The Teenage Idol Allegedly Raped Case Details Emerge
The scandal unfolded when Korekore, a prominent Japanese YouTuber known for exposing industry misconduct, broadcast leaked conversations between Amamiya and Saito on his livestream. The revelations painted a horrifying picture of abuse perpetrated against the teenage idol who had only recently debuted with Pretty Chuu in May 2025.
According to the leaked information, Saito allegedly stripped and secretly photographed Amamiya while she was sleeping at producer Yurinya’s residence. When confronted about this violation, Saito initially apologized through Line app messages. However, the situation escalated when he allegedly raped the teenager while she was unconscious and impregnated her.
The abuse didn’t end there. When Amamiya discovered she was pregnant, she was forced to undergo an abortion and subsequently went on hiatus from group activities. Pretty Chuu’s management at the time publicly attributed her absence to a “chronic illness,” concealing the true nature of her trauma from fans and the public.

Producer’s Shocking Response and Industry Fallout
Yurinya, the influential producer behind Pretty Chuu with over 1.3 million social media followers, issued a devastating public statement on August 1 after learning of the allegations through social media leaks. In her Instagram post, she confirmed the reports after speaking directly with those involved and announced her immediate separation from Saito, whom she had been with for five and a half years.
“I myself first learned of this matter through this message, and after confirming with the people involved, I found that the content was generally true,” Yurinya wrote in her emotional statement. She condemned Saito’s actions as “extremely irresponsible and despicable, both as a person and as a member of society,” while expressing profound regret for the harm caused to Amamiya and the Pretty Chuu group.
The producer’s response highlighted the shocking breach of trust within the industry, as Saito had been both her romantic partner and business collaborator. Yurinya emphasized that Pretty Chuu represented her life’s work and expressed “strong indignation and deep disappointment” at Saito’s actions against her valued colleague.
Victim’s Courage and Police Involvement
Despite facing threats from Saito, who allegedly warned that revealing the truth could destroy Pretty Chuu and threatened her family’s safety, Amamiya ultimately found the courage to seek help. Feeling trapped and unsure how to proceed, she reached out to YouTuber Korekore for assistance and guidance.
The teenager’s decision to come forward proved pivotal in exposing the abuse. According to reports, Saito had attempted to buy her silence by offering 1 million yen as a settlement payment. However, after consulting with Korekore, Amamiya refused the money and instead filed a police report, demonstrating remarkable bravery in the face of intimidation.
The leaked audio recordings between Amamiya and Saito provided crucial evidence of the abuse and threats, sparking massive public outrage when they surfaced online. These recordings have become central to both the police investigation and the court of public opinion.

Industry and Public Reaction
The allegations have triggered an unprecedented wave of support for Amamiya from fans and industry observers, with many calling for stronger protections for young idols in Japan’s entertainment industry. Social media platforms have been flooded with messages of solidarity for the teenage victim and demands for accountability.
The case has reignited broader discussions about power dynamics and exploitation within Japan’s idol industry, where young performers often face vulnerable situations with limited protection from abuse. Industry critics have pointed to the need for systematic reforms to safeguard teenage performers from predatory behavior.
Yurinya’s decisive response in cutting ties with Saito and publicly supporting Amamiya has been widely praised by fans and advocates. Her commitment to restructuring Pretty Chuu’s management to ensure member safety has been seen as a positive step toward preventing future incidents.
In a touching show of solidarity, Amamiya recently posted a brief video showing her holding hands with Yurinya, accompanied by a caption expressing her determination to “work hard” with the producer moving forward. This gesture has been interpreted as a sign of the support system now surrounding the young victim.
Wider Context of Entertainment Industry Abuse
This scandal comes amid growing global awareness of sexual abuse within entertainment industries, particularly involving young performers. The case bears disturbing similarities to other high-profile incidents in Asia’s entertainment sectors, including previous K-pop scandals involving stars like Jung Joon-young and Choi Jong-hoon, who were sentenced for rape in 2019.
The Pretty Chuu case highlights the particular vulnerability of teenage performers in Japan’s idol industry, where young women often face intense pressure and limited autonomy. Industry experts have noted that the power imbalances inherent in producer-performer relationships create dangerous situations for exploitation.
The incident also underscores the crucial role that social media and independent content creators like Korekore play in exposing industry misconduct when traditional channels fail to protect victims. The YouTuber’s platform provided Amamiya with a way to seek help and ultimately bring her abuser to justice.
Legal Proceedings and Future Implications
While specific details of the ongoing police investigation remain confidential, the case is expected to proceed through Japan’s criminal justice system. The evidence provided by the leaked audio recordings and Amamiya’s testimony will likely prove crucial in any potential prosecution of Saito.
Legal experts suggest that the case could set important precedents for how sexual assault allegations are handled within Japan’s entertainment industry. The victim’s courage in coming forward despite threats and intimidation may encourage other victims to seek justice.
The incident has also prompted calls for legislative reforms to better protect young performers in Japan’s entertainment sector. Advocacy groups are pushing for stricter oversight of industry practices and mandatory safeguarding measures for teenage performers.
Moving Forward: Recovery and Reform
As Amamiya begins her recovery process with support from Yurinya and the reformed Pretty Chuu structure, the case continues to resonate throughout Japan’s entertainment industry. Yurinya has committed to implementing comprehensive safety measures and reviewing all management practices to prevent future incidents.
The producer’s pledge to “devote her life” to ensuring Pretty Chuu members can “work safely and positively” represents a significant commitment to reform in an industry often criticized for prioritizing profit over performer welfare.
This shocking case serves as a stark reminder of the urgent need for systemic changes to protect young performers from exploitation and abuse. As the legal proceedings continue and the industry grapples with its failures, Amamiya’s courage in speaking out may prove to be a catalyst for meaningful reform in Japan’s entertainment sector.
The scandal has fundamentally altered the trajectory of Pretty Chuu and highlighted the devastating personal costs of industry abuse. As Japan’s entertainment world watches the case unfold, the ultimate question remains whether this tragedy will finally drive the comprehensive reforms needed to protect the next generation of young performers from similar horrors.
