Daily time budgets of long-distance commuting workers in Tokyo Megalopolis

In Tokyo Megalopolis, long-distance commuting between residences in the sub urbs and work places in the centre of the city was examined. Using a questi onnaire, heads of household in two suburbs were asked about the influences of long commuting hours on their daily time budgets. The results showed tha t on workdays, the workers who spent longer commuting Pose and left home fo r work earlier, and came back home and retired later; accordingly, both tim e spent on in-home activities on workdays and hours slept on the day before a workday were shorter. Comparison of time budgets between the subjects wh o work 5 and 6 days per week revealed more vulnerable influences of long co mmuting hours in the former than the latter. The expected health consequenc es of these findings are discussed from a biosocial/human ecological viewpo int.
