Cafe chains and hotels are adapting to the growing population of "nomad workers" using mobile devices to work outside the office.

A Renoir coffee shop near Tokyo's Shinjuku Station is well known for such workers, thanks to its 20 power outlets provided specifically for those who need to work on laptop computers or charge mobile phones.

Operator Ginza Renoir Co. began installing more power outlets at almost all of its coffee shops in Tokyo, Saitama and Kanagawa prefectures a decade ago. Free Wi-Fi access is also being added.
