Sleeping through Class to Success

Japanese high-school students often study until late into the night and sacrifice their sleep in order to pass entrance and other exams. On the other hand, they often take a nap in the (late) afternoon, and daytime napping or inemuri is widely tolerated. This article asks what cultural and social sense it makes to keep students up for studying, when they cannot concentrate on what is being said in class. It examines notions of time and diligence based on the ethnographic findings and analyses sleep, especially inemuri, from sociological perspective.
