The all-weather track & field stadium has a 400m 9-lane track. It has acquired third level authorization from the Japan Association of Athletics Federations and is also the home ground of Waseda's running team. The stadium was named in 2005 to commemorate the 100th anniversary of the birth of Mikio Oda (now deceased). Oda was the first Japanese athlete to win a gold medal, which he achieved in the triple jump at the 1928 Olympic Games in Amsterdam. Oda was the first athlete to be honored by Waseda University for his contribution to sports.

There is an indoor competition pool of 50m x 25m with a depth of 1.3 to 4m, a diving pool with a depth of 5m, and a flowing water laboratory.

This building underwent major renovations in 2018. It features a training room with different equipment. The Practice Room #1 is primarily for ball-based sports, while the Practice Room #2 contains mats and gymnastics equipment. It also has a dedicated martial arts hall for judo and others.
