Youths attend their Coming of Age Day celebration ceremony at Yokohama Arena. "I came as I've got my kimono ready and am taking steps to prevent infection. I'm not that worried," Mei Ohno, a college student, told Reuters at Yokohama Arena. "I've just met my old friends after a long time. I'm having a good time. After the ceremony, I'll take photos with my friends at the station, and then go straight home."
