A powerful storm slammed into central Japan on Sunday, bringing heavy rains as it churned across western areas already devastated by floods and landslides.

Typhoon Jongdari, packing winds of up to 180 kilometres (110 miles) an hour, made landfall at Ise in the Mie prefecture at around 1 am (1600 GMT Saturday), according to the nation's meteorological agency.

It weakened after making landfall and was downgraded to a tropical storm, according to the agency, but many provinces stayed on alert.

"We have been on the emergency alert the whole time since the rain disaster" in early July, said Koji Kunitomi, a crisis management official at western Japan's Okayama prefecture, referring to deadly rains earlier this month.

"Fortunately, so far, we haven't seen new flooding," he told AFP.

The storm, after unleashing torrential rain over eastern Japan, was moving further west mid-day Sunday, and authorities in western Japan urged tens of thousands of residents to evacuate before the rain intensifies.

TV footage showed high waves smashing onto rocks and seawalls on the coastline southwest of Tokyo, and trees buffeted by strong winds and heavy rain.

At least 19 people were injured across six prefectures, public broadcaster NHK said.

Rough waves shattered the window of an ocean-view restaurant at a hotel in the resort town of Atami, southwest of Tokyo, late Saturday.

"We didn't expect this could happen... Waves gushed into the restaurant as the window glass broke but we are grateful that customers followed evacuation instructions," an official at the hotel told AFP.

"Fortunately no one was seriously hurt," she said, adding five people suffered cuts from broken glass as they fled.

The storm was moving across the western Chugoku region, where record rainfall in early this month unleashed flooding and landslides, killing around 220 people.

It was Japan's worst weather-related disaster in decades, and thousands of the affected are still in temporary shelters or damaged homes.

The weather agency warned of heavy rain, landslides, strong winds and high waves, and urged people to consider early evacuation.

In Japan, evacuation orders are not mandatory and people often remain at home, only to become trapped later by rapidly rising water or sudden landslides.

Some critics said the orders in Chugoku were issued too late.

Japan is now in typhoon season, and is regularly struck by major storm systems during the summer and autumn.

'unprecedented' heatwave has killed at least 65 people in one week, with the weather agency now classifying the record-breaking weather as a 'natural disaster'.

In the week to Sunday, at least 65 people died of heat stroke while 22,647 people were hospitalised, the Fire and Disaster Management Agency said in a statement.

Both figures are 'the worst ever for any week during summer' since the agency began recording fatalities resulting from heat stroke in July 2008, a spokesman said.

'We are observing unprecedented levels of heat in some areas,' weather agency official Motoaki Takekawa said late Monday.

The heatwave 'is fatal, and we recognise it as a natural disaster,' he told reporters.

Eighty people in total have died from the heat since the beginning of July, and over 35,000 have been hospitalised. Many of the victims have been elderly people who were not using air conditioning.

Among those killed was a six-year-old school boy who lost consciousness while returning from a field trip.

'As a record heatwave continues to blanket the country, urgent measures are required to protect the lives of schoolchildren,' top government spokesman Yoshihide Suga told reporters today.

The government said it would supply funds to ensure all schools are equipped with air conditioners by next summer.

Less than half of Japan's public schools have air conditioning, and the figure is only slightly higher at public kindergartens.

Suga said the government would also consider extending this year's summer school holidays as the heatwave drags on. 

Temperatures reaching over 104F (40C) were registered for the first time in Tokyo's metro area on Monday, where the government is promoting Uchimizu, a tradition where water is sprinkled onto the ground, as part of a summer heat awareness campaign.

It was marginally cooler on Tuesday, but temperatures remained well above normal in most of the country, and little relief is forecast. 

The agency warned that much of the country will continue baking in temperatures of 95F (35C) or higher until early August.

Officials have urged people to use air conditioning, drink sufficient water and rest often.

Japan's summers are notoriously hot and humid, and hundreds of people die each year from heatstroke, particularly the elderly in the country's ageing society.

The heatwave follows record rainfall that devastated parts of western and central Japan with floods and landslides that killed over 220 people.

And many people in the affected areas are still living in damaged homes or shelters and working outdoors on repairs, putting them at great risk.

The record-breaking weather has revived concerns about the Tokyo 2020 Olympics, which will be held in two years time in July and August.

Tokyo governor Yuriko Koike this week promised that the heat would be given the same priority as measures to counter terrorism.

'It's just as important because the purpose is also to protect people's lives,' she told reporters, comparing Japan's summer to 'living in a sauna'.

Japan recorded its highest temperature ever on Monday as a deadly heatwave continued to grip a wide swath of the country and nearby South and North Korea. 

About 10 people have died in South Korea as a result of the heat. 

The mercury hit 106F (41.1C) in Kumagaya, a city in Saitama prefecture about 65 kilometers (40 miles) northwest of Tokyo, the Japan Meteorological Agency said. 

That broke the previous record of 105.8F (41C) in Ekawasaki on the island of Shikoku on August 12, 2013.

Two lingering high pressure systems have trapped warm and humid air above the region, bringing record high temperatures for nearly two weeks.  

Although the worst of the heatwave is expected to conclude this week, authorities have urged people to stay inside and use air conditioning.

Other steps include developing road pavements which emit less surface heat, setting up mist sprays and planting tall roadside trees.

Ms Koike also cited traditional ways of cooling in Japan, such as hanging straw screens and spraying water on road surfaces.

'But our traditional wisdom is not enough to beat the heat like this,' she acknowledged, 'so we will be using cutting-edge technology.'

The 10 people who died in South Korea succumbed to heatstroke and other heat-related causes, seven of them last week, the Korea Centres for Disease Control and Prevention said.

About 1,040 people have fallen ill because of hot weather from May 20 to July 21, an increase of 61 per cent over the same period last year, it added.

South Korea's highest-ever morning low was recorded in the city of Gangneung, where the temperature was 87.8F (31C) at 6.45am on Monday. The morning low in Seoul was 84.6F (29.2C), a record for the country's capital, according to South Korea's weather agency.

The mercury hit 103.8F (39.9C) in the south-eastern town of Hayang, the highest temperature in the country so far this year.

In North Korea, residents fanned themselves on crowded trolleys or protected themselves from the sun with parasols as temperatures in Pyongyang, the capital, reached 93.2F (34C). 

Weather reports said even higher temperatures were recorded on the country's eastern coast.
