Heat Stroke caused by hot and humid condition comes to an issue in Japan. WBGT(Wet-bulb Globe Temperature: Yaglou and Minard, 1957) is a standard index to set down the rule for workers or athletes, but it's difficult and annoying to measure WBGT continuously. In order to calculate WBGT, we have to observe dry-bulb temperature, humidity and globe temperature simultaneously. From June to September in 2005 summer we construct a continuous observation system for globe bulb temperature and observe one minute interval data. The maximum temperature was 58.4 degree Celsius and the difference between a dry-bulb temperature and a globe temperature was exceeded to 23.1 degree Celsius. And for an observation network in near future, we tried simultaneous observation in 8 cities by WBGT-101 (Kyoto Electronics Manufacturing Co. Ltd.) with medical researchers, and we could get simultaneously WBGT data covered Japan.
