Sad news for Doraemon fans as the upcoming Doraemon new movie for 2014, "Stand By Me" is going to be the final story in the Doraemon franchise and by the looks of the new trailer, "Stand By Me Doraemon" is going to be a tearjerker.

The official website for "Stand By Me Doraemon", the first 3D CG film starring the famous robot cat Doraemon, uploaded a new teaser trailer on Youtube. The narrator states that this is, "Doraemon's first - and final - story." Doraemon tells Nobita, "I can't stay here anymore." The tagline at the end of the video reads, "To everyone who has experienced childhood."

From the looks of it, the movie will focus on Doraemon leaving Nobita and how Nobita will deal with Doraemon leaving. Just like"Toy Story 3" it will probably deal with the theme of growing-up and leaving the child-like life behind.

The film will open in Japanese theaters on August 8.

The manga creator duo Fujiko Fujio (Hiroshi Fujimoto and Motoo Abiko) created Doraemon in 1969. In the story, the robotic cat was sent by a boy in the future to the present day to help the boy's hapless grandfather, Nobita. Doraemon, Nobita, and other children deal with everyday childhood issues, solve (and cause) problems with the gadgets in Doraemon's fourth-dimensional pocket, and embark on escapades through time and space.

49-year-old Takashi Yamazaki (Returner, Always: Sunset on Third Street, Ballad, Space Battleship Yamato) and 48-year-old Ryûichi Yagi (Pénélope tête en l'air line director, Moyashimon 3D CG director) are helming this 36th Doraemon film after collaborating on Japan's first feature-length 3D CG anime film, Friends: Mononoke Shima no Naki. Yamazaki also wrote the screenplay.
