TOKYO — Heavy rain flooded some streets and halted rail and air traffic in Tokyo on Thursday with more storms forecast.

Twelve centimeters (4.7 inches) of rain falling in just one hour in the capital, according to the Japan Meteorological Agency.

Air traffic control and other ground services at Tokyo’s Haneda Airport were halted because of lightning, preventing aircraft from taking off.

Railway operations were also temporarily suspended, including the bullet train and other lines in the region.

Across Tokyo, the rainstorm flooded streets and some social media users reporting seeing hail. According to the Tokyo Electric Power Company Holdings, more than 7,000 homes in Tokyo were without power at one point. By late Thursday, power has been restored to most of them.
