Japan is bracing for record rainfall from a powerful typhoon expected to move close to Tokyo on the country's eastern coast
Authorities have issued a rare evacuation emergency alert, fearing the storm could trigger landslides and floods
Some 300 flights have been cancelled and some train services suspended
The worst is likely to come in the next couple of hours, writes our Tokyo correspondent
Dujuan, Japan's 25th storm of the year, has sustained winds of 130km/h (80.8mph) and gusts of up to 194km/h. It could bring up to 350mm of rain to the Tokai region
The storm is the latest in a wave of storms in the Pacific, made more intense by this year's "super El Niño", which has warmed the ocean and fuelled the formation of storms
