Threat of widespread flooding and landslides compounded by earthquake in Chiba prefecture
Four people were killed and 17 were missing after the most powerful typhoon to hit Japan in decades paralysed Tokyo, flooding rivers and putting millions under evacuation warning before it ploughed up the north-eastern coast.
Authorities lifted rain and flood warnings for the Kanto region around a becalmed Tokyo before dawn but imposed them on areas further north after super-typhoon Hagibis blasted through the capital.
Attention focused on Fukushima, where Tokyo Electric Power Co overnight reported irregular readings from sensors monitoring water in its Fukushima Daiichi nuclear plant, which was crippled by the 2011 earthquake and tsunami.
Four people died in Chiba, Gunma, Kanagawa and Fukushima prefectures surrounding Tokyo, according to public broadcaster NHK. Among them was a man in his 60s who was found with no vital signs in a flooded apartment in Kawasaki, NHK said. Seventeen were missing early on Sunday, it said.
