>> Japan is sweating through a month of deadly heat. At least 14 people have died in the Tokyo area since the start of July, and thousands more have been sent to hospital. Summer has always been hot and humid in the country, however, this year has had levels not seen since records began.
On Thursday, the high in the ancient capital of Kyoto stood at almost 40 degrees Celsius, or 105 degrees Fahrenheit. The same day, a trade fair in Tokyo offered some prospects for relief concocted by hopeful inventors. Industrial-strength mist sprayers, road coatings to absorb the heat, and a jacket with built-in fans.
>> By turning on the battery of the jacket, fans draw in outside air to evaporate the wearer's sweat, and that cools them.>> There was even a cooling jacket for dogs. On the more serious side, Japans hot summers can be a struggle for construction workers. And a lot of the inventions here, like the so-called human air conditioner, try to help manual laborers chill out on the job.
>> There are a lot of times where we work outside with no shade, so this is the best thing, apart from staying hydrated, to fight off heatstroke.>> The heatwave has also sparked concern over Japan's Summer Olympics, less than two years away, Japan's aiming for 40 million visitors a year by 2020.
Beating the heat during the games will be critical, and organizers are taking it seriously. They're already planning on mist fans, and Tokyo 2020 officials tell Reuters, they'll set guidelines for canceling events for when it's just too hot to handle.
