Doraemon: Obaachan no Omoide

Nobita finds an old stuffed bear and is overwhelmed by memories of his grandmother, who died when he was very young. Wanting to see her once more, he asks Doraemon to take him back to the days when she was still alive.

In the past, Nobita must watch from a distance because his younger self and family cannot understand who this older boy is. Yet his grandmother's warmth remains exactly as he remembers it, and a simple wish she shares with him gives Nobita a chance to repay some of the love he never had time to appreciate as a child.
