Mater Dei College signed a sister school agreement in 2008 with Fukui High School in Japan and has enjoyed a long standing annual exchange program with them. Students studying Japanese in Year 11 have the opportunity to participate in a two week Study Tour of Japan every April.  

Students spend a week travelling around  Tokyo, Nara, Kyoto, Hiroshima and Osaka; experiencing the modern and traditional aspects of Japan and a visit to Disneyland.  The following week students home-stay with a Japanese family, attending school and going on excursions. They also have the opportunity to host students from Japan in their own homes later in the year when they visit Australia.
