A strong typhoon stuck near Tokyo on Monday, with heavy rain and winds grounding more than 400 flights as officials warned of landslides and flooding.

Typhoon Mindulle made landfall at about 12:30 pm (0330 GMT) in Tateyama city, roughly 80 kilometres (50 miles) southeast of Tokyo, the Japan Meteorological Agency said.

As of noon, the storm was packing gusts up to 180 kilometres per hour and heading north at a speed of 20 kilometres per hour, the agency said.

There were no immediate reports of casualties or significant damage.

"In Tokyo... please exercise caution for landslides, flooding in low lying areas, surging rivers, violent wind and high waves," the weather agency said.

Downpours across the greater Tokyo region caused rivers to swell, with television footage showing gushing waterways close to overflowing but staying within their banks.

The storm has caused airlines across the country to cancel a total of 425 flights, mostly to and from Tokyo's Haneda airport, national broadcaster NHK said.

Japan Airlines told AFP it cancelled 185 domestic flights, affecting 33,692 customers, while All Nippon Airways cancelled 112 domestic flights, affecting 26,500 passengers.

Most major commuter train services in Tokyo and its surrounding region operated normally, including bullet trains, according to East Japan Railway, the region's biggest railway operator.

Some lines, however, suffered from temporary delays and stoppages.

Separately, typhoon Kompasu, which hit Japan's northern main island of Hokkaido Sunday, was downgraded to a temperate depression by early Monday as it moved away into the Sea of Okhotsk, according to the weather agency.

Heavy rains since Saturday caused high waves and rivers to flood on the island, where rescue workers found a male body Monday morning.

Police did not immediately link the death to the storm, but local media said the body might be the owner of a vehicle that was stranded due to heavy rains.

The local Hokkaido government has so far said the storm has caused only three minor injuries.
