Resident assistants (RAs) are reliable Japanese peers for international students to depend on in their life in Japan. Selected Japanese students of Hiroshima Shudo University live with international students at i-House, offering a wide variety of support and guidance regarding campus life, things they need to know in their everyday lives, shopping, hospitals, etc. Currently, three Japanese students are working as RAs for a period of two years. RAs also receive some benefits of living in a global, international environment despite being in Japan: privileged to have opportunities to experience and appreciate different cultures, develop their English skills, and make friends from various countries.
