The Tokyo Metropolitan Government will begin using paper straws on a trial basis from October to help reduce the amount of plastic waste.
The paper straws will be provided at 3 cafeterias at the Tokyo government building in the capital's Shinjuku district.
Tokyo Governor Yuriko Koike visited one of the cafeterias on Friday. She says she hopes the use of paper straws will encourage people to think about environmental issues.
The Tokyo government will purchase 20,000 paper straws, which are several times more expensive than plastic ones.
Officials will conduct a survey on paper straw usage and will also draw up measures to cut plastic waste.
Some city councils in the United States have banned plastic straws. A number of Japanese restaurant chains are planning to phase them out.
