A high pressure system raised temperatures across Japan on June 17 morning, causing intense summer-like heat despite the rainy season.
The heat is expected to remain at its peak until around June 20 in many places, the Japan Meteorological Agency said.
'The rainy season carries a risk of heatstroke due to high humidity,' said Saitama Jikei Hospital deputy director Tsuyoshi Fujinaga, an expert on the condition. He warned that many people are not yet accustomed to the heat and tend to get careless about the danger during this season.
From May to June 8, 3,833 people were taken to hospitals due to heatstroke, according to preliminary figures from the Fire and Disaster Management Agency.
That figure is higher than the 3,665 recorded during the same period last summer, which ended up seeing a total of 97,578 sent to hospitals for heatstroke between May and September, the highest since statistics began in 2008.
The report showed that 27.8 per cent of heatstroke cases occurred at home, followed by 20.2 per cent on streets and 14.7 per cent on outdoor train platforms and in parking lots.
This month, an 86-year-old woman in Koto Ward, Tokyo, was diagnosed with mild heatstroke after experiencing headaches and nausea while taking a nap in her living room. She had kept the windows closed all day due to rain but avoided using the air conditioner as 'It's not summer yet.'
Mr Fujinaga said heatstroke in the rainy season is caused by high humidity, which makes it difficult for sweat to evaporate, resulting in the body retaining more heat.
It is also important to be aware of hidden dehydration, in which the body loses water unnoticed, he said. High humidity keeps people from feeling thirsty, allowing them to dehydrate unnoticed and increase the risk of heatstroke.
'Heatstroke in the rainy season progresses gradually, and you hardly notice something is wrong,' he said. 'Don't let your guard down just because it's not summer yet.' THE JAPAN NEWS/ASIA NEWS NETWORK

Japan issues multiple heat alerts amid soaring temperatures
In June alone, record temperatures were logged in 14 weather stations across the country. PHOTO: AFP TOKYO – Japan issued multiple heat alerts across the country as temperatures soared, touching 36 deg C in Tokyo prefecture on June 18. Fifty-seven people were transported to the hospital in Tokyo on June 18 for heat-related illnesses NHK reported, citing the fire department. In June alone, record temperatures were logged in 14 weather stations across the country, according to the Japan Meteorological Agency. The alerts come after record-breaking heat last summer resulted in the government passing tougher rules that require employers take adequate protection from extreme temperatures. In 2024 there were 30 workplace deaths and roughly 1,200 injuries associated with high temperatures, according to the health ministry. Heatstroke is a potentially life-threatening condition caused by dangerously high body temperature that can result in severe organ damage if not treated quickly. There were almost half a million heat-related deaths annually between 2000 and 2019, according to a report in 2024 by the World Health Organisation. Along with public health impacts, higher temperatures can impact worker productivity and there's growing concern about the economic toll that heat waves have on economies. Global average temperatures exceeded 1.5 deg C above pre-industrial levels for the first time in 2024 and new highs are forecast to be recorded over the next five years, according the World Meteorological Organisation.

Scores of people die each year during the rainy season due to flash floods and landslides across India. PHOTO: EPA-EFE At least 18 dead as rains lash west India state AHMEDABAD - At least 18 people have died since June 16 as torrential rains lashed parts of India's western Gujarat, state officials said. Disaster response teams have been deployed to help residents in the south of the state, who are bracing themselves for more heavy monsoon rainfall. 'Eighteen people have lost their lives in rain-related incidents, while dozens have been rescued across low-lying areas by disaster response teams,' the state government said late on June 17. The worst-hit areas included Palitana and Jesar towns, which on June 17 registered 867mm of rain over the past 24 hours. State relief commissioner Alok Kumar Pandey said the 18 deaths were the result of storms, lightning strikes, and structural collapses due to rough weather. 'The state is fully geared to handle the situation, and inter-departmental coordination is being intensified to ensure swift relief and rescue operations,' Mr Pandey said. Those rescued included 18 farm labourers who were trapped in mango orchards in the Gadhada area, and 22 people in Surendranagar district where waters from an overflowing river gushed into their homes. India's annual monsoon season from June to September offers respite from the intense summer heat and is crucial for replenishing water supplies. But scores of people die each year during the rainy season due to flash floods and landslides across India, a country of 1.4 billion people.
