This study is a result of an analysis of data collected by participatory observation of international student labor at a Japanese pub （izakaya Z） located in downtown Tokyo between October 1and November 31, 2017. The purpose of this study is to figure out why working places with poor conditions in the downtown area hire international students as their part-time workers, how they work under harsh working environment. The observation showed that international student part-time workers, especially those who receive almost no money from their home countries, need a certain level of fixed income every month to live in Japan, and izakaya Z satisfied their desired income by offering working hour assurance system. In other words, the stability of income and relatively bad working conditions are exchanged. International student part-time workers deliberately slow down their working speed to resist discrimination in the workplace, pretending not to be able to understand Japanese. While emphasizing the spirit of hospitality, the Japanese manager at izakaya Z forced international student part-time workers to aware of the process of work by themselves without a detailed explanation, complaining that the workers would ignore his instruction if they are too fluent in speaking Japanese. Behind this situation, there was a structural labor shortage problem which makes service industry companies hire international student labor.
