Why did Okamura have illicit affairs?
One reason is that she has a kind of sexual addiction. According to Cyzo, one of leading monthly magazines in Japan, she said to her friend, "I'll go mad if I can't have sex at least once a month."
Another reason is the corporate culture of NHK. Compared to other companies, illicit affairs happen in NHK more frequently. For example, according to Shukan Bunshun, Sae Nakarai(半井小絵), who had appeared on "NHK News 7" as Okamura's predecessor, had an illicit affair with Yoshinori Tateyama(建山義紀), an baseball player.
