Stand by Me Doraemon (STAND BY ME ドラえもん) is a 2014 Japanese 3D computer-animated science fiction comedy-drama film based on the Doraemon manga series and directed by Ryūichi Yagi and Takashi Yamazaki. It was released on 8 August 2014.
The plot combines with the short stories "All the Way From the Country of the Future", "Imprinting Egg", "Goodbye, Shizuka-chan", "Romance in Snowy Mountain", "Nobita's the night Before a Wedding" and "Goodbye, Doraemon..." into a new complete story – from the first time Doraemon came to Nobita's house to Doraemon bidding farewell to Nobita.
Nobita Nobi is a fourth grader who constantly gets failing grades in his subjects due to his laziness and is always bullied by his classmates Suneo Honekawa and Takeshi "Gian" Goda. His great-great grandson from the 22nd century, Sewashi, who watches him every day, travels to Nobita's timeline while bringing along his robotic cat Doraemon. Sewashi reveals that if Nobita keeps up his act, he will have a disastrous future: he will marry Gian's sister Jaiko, have his private company burned down, and will be left with a great debt. To circumvent this, he orders Doraemon to help Nobita, modifying Doraemon's nose to prevent him from returning to the future unless Nobita gains a better future.
