Landslides and flooding caused by torrential rain in Japan have killed another 21 people in what has become one of the deadliest natural disasters to hit the country since the earthquake and tsunami at Fukushima in 2011. A total of 176 people have been killed since the downpour began late last week, Japanese Chief Cabinet Secretary Yoshihide Suga said Wednesday. Another nine are missing. Japanese Prime Minister Shinzo Abe was in Okayama Prefecture Wednesday morning, surveying the damage in one of the hardest-hit areas.
