Tokyo, July 8, 2018 (News Wires) -- The death toll from unprecedented rains in Japan rose to at least 76 on Sunday after rivers burst their banks and forced several million people from their homes, media reports said, with more rain set to hit some areas for at least another day. Torrential rains pounded some parts of western Japan with three times the usual precipitation for a normal July and set off landslides and sent rivers surging over their banks, trapping many people in their houses or on rooftops. "We've never experienced this kind of rain before," an official at the Japanese Meteorological Agency (JMA) told a news conference. "This is a situation of extreme danger." At least 64 people were killed and 44 missing, national broadcaster NHK said after the death toll had been put at 49 overnight. Among the missing was a 9-year-old boy believed trapped in his house by a landslide that killed at least three others, one of them a man in his 80s. Helicopter footage showed people on their roofs waving for help in Kurashiki, and soldiers rescuing children by boat from a flooded river in Hiroshima.
