For their summer project, Nobita is tasked with studying his hometown's history. Alongside Doraemon, they use a device known as Time Camera to capture images of various landmarks throughout different eras. Their final photograph reveals Momotaro, a renowned Japanese folk hero, pulling a cart filled with riches. Later, Nobita's mother meets a foreigner who displays a photo of someone dressed as a samurai that closely resembles Momotaro. This individual inherited the image from their ancestors and journeyed to Japan in search of its origins. This leads Nobita to question whether Momotaro was indeed a real person. In order to unravel this mystery, he embarks on a trip through Japan's past alongside Doraemon, Shizuka, Takeshi, and Suneo.
