The governor of Tokyo has urged people to wear turtlenecks this winter to stay warm and reduce energy consumption.
Yuriko Koike said wearing turtleneck sweaters could help reduce energy bills.
“Heating the door has a thermal effect. I wear a turtleneck too, and wearing a scarf also keeps you warm. This will save electricity,” Yuriko Koike told reporters on Friday.
“This is one of the tools to overcome the harsh winter energy climate together.” She said that French President Emmanuel Macron “leads the way in turtlenecks”.
Japan has long run an annual “cool biz” campaign that encourages casual office dress to save energy during the country’s sweltering summers.
The winter variant is aptly labeled as “warm biz”.
Japan – which aims to become carbon neutral by 2050 – has faced pressure on energy supplies like many countries since Russia’s invasion of Ukraine in February.
In August, Japanese Prime Minister Fumio Kishida called for a revival of the country’s nuclear power industry in an attempt to address rising costs of imported energy.
But such a move would likely prove controversial after the 2011 Fukushima nuclear disaster, triggered by a massive tsunami, which led to the shutdown of many reactors over safety fears.
Eleven years later, 10 of Japan’s 33 nuclear reactors are back in operation, although not all are operational year-round and the country remains heavily dependent on imported fossil fuels.
