タイミングからみた夫と妻のタイムプレッシャ

Japanese husbands sleep longer than their wives. This is a solitary exception among the countries in which time use data are available. In the countries other than Japan, husbands sleep shorter than at least their nonworking wives. In many countries, they also sleep shorter than their employed wives. This research examines the factors of the longer hours of sleep of Japanese husbands by timing of sleep. Hours of sleep are determined by the bedtime and the hour of rising. This research focuses on the hour of rising. Analyses in this paper are based on data of 2001 Survey on Time Use and Leisure Activities conducted by Statistics Bureau, Ministry of Public Management, Home Affairs, Posts and Telecommunications, Japan. The average hour of rising of wives was earlier than that of their husbands. Among wives, the average hour of rising of employed wives was earlier than that of nonworking wives. Actually, wives in 55% households got up earlier than their husbands and wives in 25% households got up later than their husbands. During two hours after getting up, wives spent one hour on housework and husbands spent two minutes on housework. Time pressure on employed wives was stronger than on their husbands.
