Tokyo - Eight people died of heat stroke and about 1,800 were taken to hospital Saturday after an intense heat wave enveloped large parts of Japan, a news report said.
The casualties all occurred in the west of the country, where temperatures exceeded 38 degrees Celsius, broadcaster NHK cited the Japan Meteorological Agency as saying.
Among the dead was an 81-year-old man whose body was found in a rice paddy in Toyooka city, about 450 kilometres west of Tokyo, the report said.
As of 8 pm (1100 GMT), at least 1,810 people - including 116 in Saitama prefecture and 103 in Osaka prefecture - had been hospitalized across the country, NHK said.
The meteorological agency expected another heat wave to hit the country on Sunday, and advised the public to drink adequate amounts of water to prevent heat stroke.
