The most popular pop music artist in Japan, Hikaru Utada, aka. Hikki, is recovering from side effects from medication taken after an operation in early April to remove a benign tumor from an ovary. The singer posted on her official website, “I’m sorry for surprising you and making you worry. I am going to rest a bit until I can work properly, as announced by my father and Toshiba-EMI. Now I am at home resting quietly. Don’t worry!” Hikki signed a deal earlier this year to release her first album in English.
