Since the Meiji era, Waseda University has been a doorway to Japan for a great many international students. Even today, the 4,917 international students accepted by Waseda (as of November 1, 2015; the same applies hereafter) represents the largest such number in Japan. For the future, the CJL seeks to grow to become the Japanese educational institution of a university welcoming more than 10,000 international students. For international students, the CJL provides an entryway to learning at Waseda University as well as a supportive process towards achieving self-actualization during university. For such actualization to be achieved, connections with different organizations on campus, off campus and in society at large are becoming more important than ever before. As globalization continues apace, a learning environment rich in diversity and individuality for international students must not be confined to the CJL but be cultivated within undergraduate and graduate schools and the university as a whole. The CJL offers openness in addition to diversity and individuality and has a core role to play in building a robust learning environment.
