This study aims to report on the process of expanding the provision of Halal menus in a Japanese university. In Japanese language classes and Japanese language teacher training classes at Hiroshima University, the issue of meals for Muslim students has been taken up, and students have been instructed to be considerate of religious meals. Furthermore, considering the recent increase in international students, universities will be required to provide a variety of food options for Muslim students. Focusing on the provision of Hiroshima University Co-op’s Halal menu, this study conducted interviews and surveys with Muslim international students. The two key findings were: (1) Even though Muslims may belong to the same religion, each Muslim has a different perception about halal food, and (2) Muslim students do not necessarily require restaurants or cafeterias to be halal certified by a third-party organization. According to the results, an important consideration in meal provision for Muslim students is to provide them with enough information to make their own decisions about what they can eat. Hiroshima University Co-op made efforts such as creating a "Halal Muslim Policy," "Halal Logo," and worked on information disclosure about food. The efforts described in this paper have contributed to allowing Muslim students to eat similar food as non-Muslim students and faculty in the same place on campus.
