SocietyDeadly daytime heat turns Japanese farmers nocturnal

Japanese farmers are shifting to nighttime schedules as dangerous summer heat makes daytime work unsafe. North of Tokyo, Motoaki Iijima harvests flowers in a lit greenhouse after sunset after a worker suffered heatstroke there while picking sunflowers three summers ago. Nearby poultry farmer Tetsuya Usuba now wakes his flock at 2:30 am to eat.
