Japan continued to experience a sweltering summer heat wave on Thursday with daytime highs of over 35 degrees Celsius recorded in many areas.
The Meteorological Agency says a high pressure system covering vast areas from western through northeastern Japan, combined with an influx of warm air, is bringing clear skies and high temperatures to the archipelago.

Temperatures are unlikely to drop below 25 degrees overnight through Friday over a wide area and the scorching weather is expected to continue.
A high of 37 degrees is forecast for Saitama City, Saitama Prefecture, 36 degrees for Kyoto City and central Tokyo, 35 degrees for the cities of Okayama, Nagoya and Fukushima on Friday.
