Japanese singer and actress Noriko Sakai smiles to the media after her news conference in Tokyo on Saturday, announcing her return to the entertainment industry. Sakai, 41, finished her three-year suspended sentence Friday after being convicted of drug use in 2009. Sakai, who is popularly known as Nori-P, will return to the stage next month in a play about Sengoku era warlord Oda Nobunaga. Sakai thanked her fans for supporting her and said her drug use was a stupid mistake. In a sign of her “rehabilitation,” her ankle tattoo has gone.
