The Japanese sweat. June was a record breaking month for the archipelago, with nine days of abnormally high temperatures. Thirty-five of the 47 Japanese departments have experienced temperatures never seen since the beginning, in 1875, of the recording of these data. Tokyo has endured six straight days of over 35 degrees. June was, however, only a prelude to a summer that forecasters are predicting to be warmer than usual, with its cortege of daily alerts falling on mobile phones, calling for people to “avoid all outdoor sporting activity” and to “quench your thirst to escape heatstroke”.
