( CNN ) -- The death toll climbed to 10 in Japan as the remnants of former Typhoon Roke raced into the northern Pacific on Thursday , government officials said . Four people are missing , according to local government officials . Roke hit the Japanese mainland Wednesday morning as a powerful Typhoon , packing winds of up to 167 kph ( 103 mph ) . The storm caused widespread flooding and disrupted transportation throughout the island nation a day earlier . The storm hit as Japan is still recovering from the devastating earthquake and tsunami that struck in March , killing more than 15,000 people . Ahead of the storm , there were fears that it would affect Tokyo Electric Power Co. 's Fukushima Daiichi plant , which went into a nuclear crisis after the March disaster . TEPCO officials canceled outdoor construction at the plant . Plant officials said Thursday that they have not seen any major problems at the plant due to Roke . At one point before the storm made landfall , about 1 million people were urged to evacuate from vulnerable areas as heavy rain pounded central and western Japan . Some downpours came up to 50 millimeters ( 2 inches ) an hour , and some regions received more than 450 millimeters ( 17 inches ) over a day , according to Japanese public broadcaster NHK . CNN 's Yoko Wakatsuki and Junko Ogura contributed to this report .
Roke is no longer a tropical storm . The National Hurricane Center says that the center of Tropical Storm Lee has weakened to a Category 1 hurricane. Plant officials report no major problems at the stricken Fukushima Daiichi nuclear plant .
