All 15 people reported missing amid the severe flooding in Ibaraki Prefecture have been located and are safe, authorities said Tuesday.

While all those listed as missing in the disaster have now been accounted for, police and firefighters continued their search operations as the entire picture of the damage is not yet known, including in the still-inundated city of Joso.

"As the telephone lines were restored, we were able to get in touch with more people who returned home when the flood water receded," an official from the Ibaraki Prefectural Government told a news conference in Joso.
