With the implementation of the amended "Immigration Control and Refugee Recognition Act" in 1990, there was a sharp increase in the immigration of Japanese descendants from Central and South American countries who were "permanent residents." As a result, there has been a growing demand for multicultural coexistence in local communities. Multicultural coexistence refers to individuals from different nationalities and ethnicities acknowledging and accepting each other's cultural differences while striving to build an equal relationship. They actively contribute to the local community, showcasing their unique qualities and abilities and living together harmoniously. Additionally, due to the rapid globalization of the economy, there has been an increase in foreign residents and international students from various parts of the world. Professor Yuuki has been consistently engaged in research, education, and practical activities for over 20 years since joining Gunma University. She has undoubtedly been at the forefront as a university professional involved in multicultural coexistence, continuously pushing boundaries.
