Shuna Amamiya, a member of the idol group “Pretty Chuu” produced by popular influencer Yurinya, has revealed that she was sexually assaulted by Yurinya’s romantic partner, Taichi Saito (29). The allegation came to light on August 1, causing widespread shock across the entertainment industry. On the night of August 2, Amamiya appeared on the livestream of exposé-focused broadcaster KoreKore, where she gave a detailed account of her experience.
Who is Shuna Amamiya?
Shuna Amamiya was an active member of the idol group “Pretty Chuu,” co-produced by Yurinya and Taichi Saito. The group held auditions in 2024 and officially announced its members on May 13, 2025, making it a newly formed unit. Amamiya was one of its central members.
For Amamiya, who had just begun her career as an idol, the assault by her producer represents a grave case of abuse of power and exploitation under the guise of professional authority.
How the Incident Was Exposed
The incident was first made public during a livestream by KoreKore, a prominent YouTuber and TwitCasting personality known for covering entertainment scandals, on August 1. During the broadcast, it was revealed that Taichi Saito had secretly filmed Amamiya while she was asleep and sexually assaulted her, ultimately leading to an unwanted pregnancy and abortion.
Following this disclosure, Yurinya posted a statement on Instagram the same day, acknowledging that “after confirming with both parties, the allegations are mostly true.”
Shuna Amamiya Appears on KoreKore’s Stream
Starting around 10:30 p.m. on August 2, Amamiya appeared on KoreKore’s stream for approximately three hours, where she gave a detailed testimony about the abuse she endured. The broadcast drew significant public attention and became a pivotal moment highlighting the problematic power dynamics in the idol industry.
Amamiya’s account made clear the realities of sexual abuse committed under the guise of professional roles, and underscored the importance of victims speaking out. Her courage is expected to encourage others in the industry who may be suffering in silence to come forward.
Who is Taichi Saito?
Taichi Saito, born on May 1, 1996 (age 29), began his career as a beauty YouTuber before moving into idol production. He was known by the nicknames “Taichikun” and “Taicho Saito.”
He had been in a relationship with Yurinya for over five and a half years, and the two ran a couple’s YouTube channel under the name “Yuritai CP.” In March 2025, they celebrated their fifth anniversary, and fans speculated that marriage might be imminent.
However, behind this public image, Saito allegedly carried out repeated sexual assaults on members of the idol group he managed. His actions toward Shuna Amamiya—ranging from secretly filming her while she slept to sexual assault and coercion into abortion—were especially heinous.
Yurinya’s Response and Industry Impact
After the incident came to light, Yurinya responded quickly, stating, “I take my responsibility as a producer seriously and deeply apologize.” She also declared a complete break with Saito, saying, “Taichikun is now a stranger to me.”
Born on November 28, 1999, Yurinya began her online career in elementary school by posting dance videos on Nico Nico Douga. She is now a prominent influencer with over 1 million TikTok followers. Yurinya expressed a strong commitment to supporting Amamiya and taking steps to prevent similar incidents in the future.
Legal Implications and Future Outlook
If Amamiya’s claims are verified, the acts in question—including illegal filming, sexual assault, and forced abortion—could fall under several criminal offenses. Since the crimes were allegedly committed by someone in a position of authority, they could carry more severe penalties.
Amamiya’s testimony may serve as a precedent for others in the entertainment industry who may have experienced similar abuse. The case also highlights the urgent need for structural reform in the idol and influencer industries, including the establishment of accessible, independent reporting mechanisms.
Social Impact and Industry Reform
This case serves as a stark reminder of the power imbalances that exist in the entertainment industry. The fact that a young, newly debuted idol found the courage to speak out makes this case particularly significant.
Amamiya’s testimony will likely accelerate calls for better working conditions within the industry, stricter oversight of individuals in power, and the creation of third-party agencies where victims can safely seek help. Improving industry-wide compliance awareness is also a pressing need.
This incident may become a turning point for reform across both the idol and influencer sectors. Shuna Amamiya’s brave action stands as an essential first step toward preventing further abuse.
