The Japan Meteorological Agency predicted that warm and damp air sliding into a seasonal front could even cause tornadoes.
Some bullet trains were taken out of service on Thursday. But certain railway companies, such as Japan Railway Company, resumed operations by Friday.
Japan's automotive industry was also affected by the disaster. Mitsubishi Motors stopped operations at a plant after being unable to receive parts.
Mazda Motors also stopped production at two plants out of concern for their employees.
