On May 7, 1933, in the Parade Ground in Joto, Osaka, three Nakajima Type 1 Fighters were donated to the IJAAF; Aikokugo #84, #86 and #87. The donors were Tamura Komajiro, "Osaka Prefecture, City, and other industry-related parties" and the "Osaka Association of Honmon Butsuryū" respectively.
In the clip we can see the donation ceremony of #84 and #86 taking place with the Shinto Priest permorming a Harai Ceremony before the two pilots are taking the fighters for a spin.
