Office space per <Office Occupant> increased slightly to 3.9 tsubo, reducing the gap
1 tsubo = approx. 3.3 sqm
with office space per <Worker Coming to the Office>Figure 1 shows the annual trend of office space per<Office Occupant> and office space per <Worker Coming
to the Office> based on the leased space and thenumbers of office occupants for the former, and theleased space and the number of workers coming to theoffice for the latter of each corporate tenant located in the23 wards of Tokyo (“Tokyo 23 Wards”).

Figure 1: Office Space per <Office Occupant and Worker Coming to the Office>(2008–2023, Tokyo 23 Wards)

The median office space per <Office Occupant> in 2023
was 3.9 tsubo, a slight increase from the previous year.
Office space per <Worker Coming to the Office> was 4.9tsubo, unchanged from 2022.

Compared to previous surveys, the difference between
office space per <Office Occupant> and that per <WorkerComing to the Office> has shrunk. We believe this to bedue to a rise in companies’ demand for office floor space,leading to an increase in office space per <OfficeOccupant>, while an increase in the number of people
coming to the office on the back of the easing ofrestrictions on workers coming to the office resulted inoffice space per <Worker Coming to the Office> beingunchanged.
For reference, the significant figure for these indicators
has been published in two digits but is now published in
one digit, with which a significant difference can beconfirmed, as a result of a re-examination.

Office space per person in Tokyo 23 Wards is smaller than in Osaka, Nagoya, and Fukuoka
By office location, the office space per person was smaller in the Tokyo 23 Wards for both <Office Occupants and Workers Coming to the Office> than in Osaka, Nagoya,and Fukuoka Cities (Figure 2).
The coming-to-office ratio at the time of the 2023 survey was relatively low in the Tokyo 23 Wards at 75.6%, indicating that telework has spread more than in other areas.
The Reference at the bottom of the page indicates office space per desk by office location calculated from the survey data as a reference value at the time of the survey.
