A massive disaster drill was held Sunday in 10 locations throughout Tokyo, with the nation's Self-Defense Forces participating on an unprecedented scale.

The drill came as residents of Miyake Island, south of Tokyo, continued to flee to mainland Tokyo due to unpredictable and increasing volcanic activity.

Authorities closed off the main street of downtown Ginza for one hour Sunday morning as participants feigning injuries moaned for help. C-130 transports from the SDF landed at Haneda Airport with medical supplies and police reinforcements from Hiroshima and Fukuoka prefectures as Ground Self-Defense Force troops advanced to the scene on the Oedo Subway Line.
