The administration in Tokyo encourages employees to give up suits and wear shorts to reduce energy consumption.

The Tokyo metropolitan administration has announced a significant relaxation of the dress code, urging employees to abandon traditional suits and adopt shorts at the office. This measure has been implemented to limit the use of air conditioning, in the context of record fuel price increases caused by the war in Iran and a heatwave that has led to the hospitalization of over 100,000 people. Authorities also suggest working from home or a morning schedule to reduce energy consumption. The initiative is part of the national campaign 'Cool Biz', launched in 2005, which promotes energy saving by eliminating jackets and ties during the summer. Although Tokyo has historically been reluctant to accept shorts at the office, climate change and global conflicts now necessitate adaptation. Japan, which relies on oil imports from the Middle East, faces an energy vulnerability exacerbated by tensions in the region.
