Doraemon: Obaachan no Omoide

Nobita is longing for his late grandmother, who passed away several years earlier. To help him, Doraemon uses a time-travel device to take him back to the past, where he can reunite with her. However, their journey is complicated by the presence of younger versions of Nobita and his friends, as well as a young Nobita’s mother, who fails to recognize either Nobita or Doraemon. They must navigate these challenges while trying to spend time with the grandmother.
