Trying to stay warm while cutting energy bills this winter? Wear a turtleneck, says the governor of Tokyo.
The governor, wearing one herself under a jacket, encouraged residents to wear turtleneck jumpers both to stay warm and as a way of reducing energy consumption.
"Warming the neck has a thermal effect. I'm wearing a turtleneck myself and wearing a scarf also keeps you warm. This will save electricity," Tokyo governor Yuriko Koike further said.
Like many countries, Japan -- which is aiming to become carbon neutral by 2050 -- has faced a squeeze on its energy supply since Russia's February invasion of Ukraine.
