Sitting in the middle of a busy Tokyo subway station, it resembles a cross between a phone box and a cupboard. But it is, in fact, a high tech single-person “office” designed for busy Japanese commuters.

The mini smart office, created by the Japanese company Fuji Xerox, aims to tap into a new generation of “teleworkers” who need to work while on the move, with a mix of technology and convenience.

The booths are as compact as they are high-tech: the monochrome spaces measure only 1.6m by 1m and stands just under 2m high, while fixtures are snugly limited to a desk, chair and LCD screen.

Behind the frosted white door, there are free wifi and power outlets while the temperature and humidity are carefully controlled to allow visitors to work in comfort year-round.

Users will be able to reserve the one-person offices online in units of 15 minutes, before unlocking and operating the spaces in the stations using their smartphones.
