Of the 18,347 people, 729 had severe symptoms, while 6,548 had less serious issues, requiring shorter stays. Those aged 65 and older accounted for 54.3 per cent of the total, the Japan Times reported.
Tokyo had the most people taken to hospitals at 1,857, followed by 1,342 in Aichi Prefecture and 1,307 in Saitama Prefecture.
Deaths were reported across 24 prefectures, with Hokkaido seeing the most at seven, followed by five each in Ibaraki and Saitama.
A high pressure system over the Japanese archipelago preserved extreme heat, said the agency.
It advised people to constantly stay hydrated and rest in cooler areas.
