Typhoon Talas never strengthened above tropical storm force, but the sheer volume of water it dumped on Wakayama and Nara prefectures was enough to generate a major natural disaster.
Thousands of people remained isolated due to washed out roads three days after the storm passed slowly over the region.
Rescuers were forced to walk through deep valleys or climb steep mountains in order to reach some of the remote villages isolated by the disaster.
Talas dumped a record of nearly 8 feet of rainfall on the Nara prefecture community of Kamikitayama, according to NHK.
The storm struck while Japan was still recovering from last March’s combined quake, tsunami and nuclear disaster.
