Only Yesterday (おもひでぽろぽろ Omohide Poro Poro, lit. "memories come tumbling down") is the sixth film by director Isao Takahata and produced by Studio Ghibli. It is based on the manga of the same title by Hotaru Okamoto and Yuko Tone. It was released on July 20, 1991. The ending theme song is a Japanese translation "Ai wa Hana, Kimi wa sono Tane (愛は花、君はその種子)" of Amanda McBroom's composition "The Rose."

Only Yesterday is significant among progressive anime films in that it explores a genre traditionally thought to be outside the realm of animated subjects, in this case a realistic drama written for adult, particularly female audiences. In spite of its subject matter, the film was a surprise box office success, attracting a large adult audience of both sexes.
