Rescuers worked by hand to clear debris from a landslide triggered by heavy rains in central Japan on Saturday, as the toll from the storms rose to 10 dead with a further three people reportedly missing.

Aerial footage showed emergency workers removing wreckage from two houses that were swept away in Chiba, southeast of Tokyo, just two weeks after a deadly typhoon barrelled through the area.

Nine people were killed by landslides and floods in the region, including two elderly men found dead in submerged cars, officials and news reports said.

A woman in her 40s was found dead near the coast in eastern Fukushima, according to a fire department official.

Police divers were deployed to search for those unaccounted for, with public broadcaster NHK putting the number of missing at three.

Thousands of people were forced to spend the night in Narita airport after train services were suspended, it added.

"Water was flowing in my garden like a river," a 75-year-old man told NHK. "Rain was heavier than during the typhoon."

Two weeks ago, Typhoon Hagibis slammed into the east coast of Japan, killing more than 80 people. Many river banks and levees that were breached during Hagibis have yet to be repaired.

The rescue effort received some relief when the Japan Meteorological Agency downgraded warnings of landslides and floods as rains eased on Saturday morning in many regions.

Non-mandatory evacuation orders were also lifted in many areas, although 1,800 people were still in shelters, NHK reported.

Heavy rains prompt Japan evacuation orders weeks after typhoon

Tens of thousands of people were advised to evacuate on Friday as Japan was hit by heavy rains just two weeks after a deadly typhoon barrelled through the country.

The Japan Meteorological Agency issued warnings of heavy rains, landslides and floods in a swathe of areas including eastern and central Japan.

"We see extremely heavy rains in areas centring around Chiba prefecture," the JMA warned on its Twitter account, referring to a region east of Tokyo.

"As risks of disasters have already increased, please be extremely vigilant about landslides, rise in river water volumes and floods as rains will continue," it said.

Non-mandatory evacuation orders were issued to more than 4,000 residents in Chiba, and tens of thousands of others were also advised to evacuate in other prefectures, public broadcaster NHK reported.

Footage showed cars splashing through roads partly inundated with water, and swollen rivers seemingly on the verge of flooding.

The Chiba prefecture announced it planned to discharge water from dams that had reached maximum capacity later Friday, raising worries of river overflows in densely populated downstream areas.

Japan was hit by typhoon Hagibis about two weeks ago, with the death toll from the violent storm now standing at more than 80.

Residents still picking up the pieces after that storm expressed frustrations over reconstruction delays and their fear of another disaster.

"I'm a bit worried that if an evacuation order is issued, we will have to leave here," a woman in Nagano in central Japan who was cleaning up mud told NHK.

Many of the river banks and levees that were breached during Typhoon Hagibis have not yet been repaired.
