Japan has unveiled a new name for days that reach 40C (104F) or above, after the country experienced its hottest summer on record last year.

The term - kokushobi - has been translated as "cruelly hot", "brutally hot" or "severely hot" day by Japanese and international media.

The name emerged as the most popular in a national online survey, with "super extremely hot day" in second place.
