A series of mudslides sparked by torrential rains killed at least four people and left five others missing in the western Japanese prefecture of Yamaguchi on Tuesday, media reports said. A nursing home for the elderly in Hofu city was hit by a landslide, prompting the military to send a rescue unit there, Jiji and Kyodo news agencies said. About 10 cars were also seen buried in one mudslide, Jiji said. Officials at the Hofu fire department could not immediately confirm the reports when contacted by telephone.
