Hanazono Rugby Stadium opened in November 1929 as Hanazono Sports Ground. The idea of building Japan's first stadium exclusively for rugby is said to have come as both a surprise and major event for the relevant authorities. The project was motivated by Prince Chichibu and the newspapers reported widely on the "Construction of the Asia's first deicated rugby stadium."

The opening ceremony was graced by the presence of Their Imperial Highnesses Prince and Princess Chichibu, and a commemorative match between an old-timers' team and a students' team was held. On the same day, Rugby Ground Station (the present Higashi-hanazono Station) was newly opened. At that time it served as a temporary station that was open only on match days.
The initial official name of Hanazono Rugby Stadium was "Hanazono Rugby Stadium of the Japan Rugby Football Association and the Western Rugby Football Association." As the stadium name indicates, it was associated with the Japan Rugby Football Association, which serves to promote rugby in Japan.
As World War II intensified, the metalic roof of the main stands was surrendered to the authorities on June 25, 1943 in accordance with the Metal Recovery Act of 1941.
