Deadly daytime heat turns Japanese farmers nocturnal

Japan's farmers are opting for more nocturnal schedules as daytime summer heat makes working conditions dangerous. North of Tokyo, Motoaki Iijima harvests flowers in his illuminated greenhouse long after sunset. The farmer was pushed to  make a dramatic change after a worker suffered heatstroke picking sunflowers in the greenhouse three summers prior. A few towns away, poultry farmer Tetsuya Usuba has also adopted a nocturnal schedule, waking his flock at 2:30 am to eat.
