Efforts are being made to reduce congestion in Tokyo during peak commuting hours in the run-up to next year's Olympics.
Officials from the Tokyo metropolitan government, the central government and some companies are working together to stagger commuting times and encourage workers to telecommute.
In a July 24 test, the average number of people using 75 JR and subway stations between 8:00 and 9:00 AM was about 3 percent less than on the same day last year.
Central Tokyo's Kasumigaseki Station saw the biggest drop in commuter traffic at 22 percent, followed by Hamamatsucho and Tochomae stations, with 12 percent decreases.
Commuter traffic in the Tokyo metropolitan area is expected to rise by about 10 percent during the Olympics.
