Berliner Tageblatt - Too hot: Buttoned-up Tokyo officials ditch suits for 'cool' shorts

The loosening of a strict dress code, particularly for men, comes as Japanese offices cut reliance on air conditioning due to high energy costs linked to the Middle East war.

On Tuesday, as temperatures in the capital soared to around 34C, at least five brave men at Watanabe's office swapped their suits for shorts.

The 50-year-old told AFP he initially found it "embarrassing" to bare his legs in the office.

"But once you wear them (shorts), you realise just how comfortable they are," he said.

He wears a formal shirt when necessary, but admitted it "feels hot".

The shorts initiative was announced this spring by Tokyo governor Yuriko Koike, citing "challenging outlook for electricity supply".

It is part of an upgraded version of "Cool Biz", an energy-saving campaign that encourages bureaucrats to ditch ties and jackets in summer, and which Koike started in 2005 when she was environment minister.

"We encourage 'cool' attire that prioritises comfort, including polo shirts, t-shirts and sneakers, and -- depending on job responsibilities -- shorts," she told reporters in April.

The scheme has sparked some envy among other Tokyo workers.

Takayuki Deguchi, a 30-year-old employee at a marketing company that still insists on suits, loves the initiative.

"I think being able to wear shorts that allow you to regulate your temperature when it's so hot is a very flexible approach," Deguchi told AFP.

However, the campaign has also sparked discussions online over whether short pants are appropriate workwear.

Sachie Koike, a 52-year-old realtor, said she was fine with men ditching a tie or jacket in summer -- but shorts were a step too far.

"I associate them with a day-off," Koike said.

"I just don't think hairy legs look very neat" in the workplace, she added.

Last year Japan sweltered through its hottest summer since records began in 1898, according to the Japan Meteorological Agency.

Temperatures rising to 40C and above have become so common that the agency in April unveiled an official designation for these extreme weather events, labelling them "cruelly hot" or "kokusho" days.

Scientists say human-driven climate change is making extreme weather more frequent, prolonged and intense.

Tokyo government worker Takuya Ozawa, 38, told AFP that he finds his journey home from work particularly hot in long trousers.

"But it feels nice and cool in shorts."
