Feeling the heat? An exhibition in Tokyo is showcasing clothes, tools and technologies that can bring a cool breeze to the hottest day.

Heat Solution Tokyo 2016 opened on Wednesday at the Tokyo Big Sight exhibition center in Koto Ward and runs through Friday.

"Most of the products are wearable items and facilities to be used inside factories to keep workers safe from heat," said Hiroyuki Kanai, a spokesman for the Japan Management Association, which organized the fair.
