Tokyo is changing its strict office rules. The government now says workers can wear shorts, T-shirts, and sneakers to the office. This is part of the 'Cool Biz' plan to save energy.

Japan faces a difficult summer with very high temperatures. Also, because of wars abroad, the cost of energy is rising. By wearing cooler clothes, offices do not need to use much air conditioning. Governor Yuriko Koike says that being comfortable helps people work better. Some workers were nervous at first, but now they enjoy the change. It shows that even old traditions can change to help the planet and stay cool!
