 note = {application/pdf, In 1999 we compared time budget structures of tulip bulb farmers in the harvest and post-harvest season in Japan and the Netherlands, by interview and questionnaire survey. Our results are as follows: 1) In Japan there are two peaks in monthly allocation of yearly labour input, June - July (harvest and post-harvest) and October (planting). In contrast, there is one peak in the Netherlands, June - July (harvest and post-harvest). In Japan labour time fluctuates month by month, while in the Netherlands it does not. 2) During the harvest and post-harvest season (9 days), Japanese farmers work for twelve to thirteen hours and sleep for less seven hours, while Dutch farmers works at most for ten and half hours and sleep for eight hours. 3) One of the reasons for the above fact is that Japanese farmers work even on Saturday and Sunday but Dutch ones do not so., Working Paper},
