The Inter-University Center for Japanese Language Studies (アメリカカナダ大学連合日本研究センター, Amerika Kanada Daigaku Rengō Nihon Kenkyū Sentā), or IUC, is a Japanese language school located in the Minato Mirai area of Yokohama, Japan.

Operated by a consortium of universities, the IUC provides advanced-level instruction to both undergraduate and graduate students and is considered one of the most selective and rigorous Japanese language programs in the world.

The programs are focused on advanced Japanese suitable for professional or academic use,[3] and prospective students must have completed at least two years of college-level training and pass a language exam to be eligible for enrollment.
