Across multiple posts in September, Noa Tsukino, 18, made her suicidal thoughts known to her social media followers.
Under different circumstances the posts by the Nagoya teen, a former member of a minor idol group and known in some circles among the city's youth, may have served as a warning and led to her getting the help she needed.
Instead, Tsukino became another victim of cyberbullying in a country where such stories have become all too familiar.
