This paper makes a comparison of time spent on housework by husbands and wives between Japan and Korea. Analyses in this paper are based on data of 2011 Survey on Time Use and Leisure Activities conducted by Statistics Bureau, Ministry of Public Management, Home Affairs, Posts and Telecommunications, Japan and 2009 Time Use Survey conducted by Statistics Korea. Housework includes cooking, cleaning, laundry, caring for adults, household chore, child care and shopping. Both Japan and Korea have features in common in time use. In both countries, husbands spend little time on housework and wives have heavy burdens of housework. Husbands in dual-income family do not necessarily spend more time on housework than those of not employed wives. Not employed wives devote more time to housework than employed wives not only on weekdays but on Sundays. In sum, from the viewpoint of time use, both Japan and Korea are far from the gender equality.
