The Ōkuma Auditorium (大隈講堂, Ōkuma kōdō), officially the Waseda University Ōkuma Memorial Hall (早稲田大学大隈記念講堂, Waseda daigaku Ōkuma kinen kōdō), is a Tudor Gothic auditorium of Waseda University in Totsuka, Shinjuku, Tokyo. Designed primarily by Kōichi Satō, construction of the auditorium was planned to begin in 1923 following the death of Waseda founder Ōkuma Shigenobu. Its construction was halted by the 1923 Great Kantō earthquake but eventually began in 1926. It opened in 1927, commemorating the 45th anniversary of the founding of Waseda University. The auditorium includes a large hall with a capacity of over 1,100 seats and a basement hall of about 300 seats. The university's activities, lectures and concerts are held in the auditorium. The clock tower chimes six times a day.
