The story begins at an undisclosed date, but was traditionally believed to have taken place in the year 2205 due to statements made in several of the publications devoted to Yamato III. However, the sequel film, Final Yamato, explicitly took place in late 2203, so after the film was released, the date of Yamato III was assumed to be early 2203.
