Given the sensitive nature of the topic, if this is about abuse, I need to approach it with care, ensuring that any report does not perpetuate misinformation or harm. It's important to respect the privacy of individuals unless there's verifiable information.

Since the user provided Japanese keywords, I should check Japanese news sources and reports. However, I have to be careful about the reliability of the sources. There might be tabloid articles or clickbait headlines that are sensationalized.

Alternatively, there might be a translation error, as the user mentioned "Japanese." Sometimes terms in Japanese can be misrendered or misinterpreted.
