It first started with her husband getting arrested because of drugs, then news broke out that a heartbroken Sakai left home and went missing.
Now the news is that she too, is wanted by the police over drug involvement and this has caused ripple effects. For one, her company Sun Music suffered a loss of RMB80 million. In return, Sun Music announced it will take a bigger role in their artistes' private lives to make sure they do not derail. The company also wants Sakai to end her marriage to restore the reputation. However, Sun Music also said if Sakai is convicted, it will end its contract with her.
A 'friend' also claimed that Sakai likes to try out all sorts of drugs, including marijuana and cocaine.
Because of Sakai's status in Japan's entertainment industry, the government has opened a meeting for this matter (her involvement in drugs) over concerns that Sakai was sending out wrong messages to young Japanese.

How did things come to this? Bad influence from her husband, perhaps? :\ I doubt the 'friend' is really a friend anyway... A real friend shouldn't be making things worse for her right now.
