Japan heat wave kills at least 4
A heat wave in Japan has raised temperatures to more than 40 C in the cities of Tokyo, Kofu and Shimanto.
High temperatures were blamed for at least four deaths on the weekend.
In Tokyo, nearly 80 people went to hospitals for treatment of heat stroke.
Tokyo and Kofu, 110 kilometres to the east, have not seen temperatures higher than 40 C since 2007, when an all-time high of 40.9 C was recorded for the two cities, above the maximum temperature of 40.6 C reported Saturday.
The Japan Meteorological Agency said early Sunday that temperatures would soar past 35 degrees in 39 of the country's 47 prefectures.
