Since the very first beginning of Ajou GSIS from 1996, International Day has had a significant role in promoting different cultures to others. More than 157 foreign students from 37 different nations take part in the festival with many ambassadors and the mayor of the city. It provides a range of activities, including an international food festival where foreign students provided traditional national food. Through this festival, International Day has become the venue where not only the students in the Ajou community but also local citizens have the opportunities to meet various cultures and enjoy the cultures around the world in one place.
