Homecoming Day

Tokyo Tech Homecoming Day Sat., May 21, 2022

Welcoming the Tokyo Tech Community

Homecoming Day is an annual event designed to bring the Tokyo Tech community together. On this day each year, Tokyo Tech opens its doors to alumni to strengthen ties, to current students to promote exchange with alumni, and to members of the local community who want to discover more about Tokyo Tech. Faculty members and students plan various events together to ensure a pleasant day for all visitors.
