Student dormitories are housing accommodations that have been prepared for students by their individual schools (they also house Japanese students in addition to international students).
Their rent is cheaper when compared to privately-owned apartments and condominiums, and they are convenient for commuting to school since they are located near their university.
Additionally, students are able to enjoy peace of mind as they focus on their studies since there are cases where there are dorm managers who are also living on-site or there are cases where meals are also provided.
