earlier kanako sachno spoke with sano about the latest situation. >> what have you been seeing and hearing on the ground? >> reporter: yes. here behind me, heavy machinery is still being used to remove the rubble from a destroyed building. it will be a long time before they can consider rebuilding. yesterday i went to one of the hardest hit areas. the infrastructure was also devastated. the water supply is cut off, and residents have been pumping from a portable supply to wash their dishes and keep themselves clean. meanwhile, heavy rain has led to severe flooding, killing around 20 people. that includes a person who survived the quakes and was living in a temporary shelter. >> what is the biggest problem people are facing right now? >> reporter: housing is a big issue. temperatures dropped right after the quakes, leaving many out in the cold. about 2.5 million people are still living in tents, but now it's getting warmer and tents absorb heat. i have seen many choose to stay outside because it's too hot. it will only get worse during the summer. temperature can reach 40 degrees celsius. t
