Crayon Shin-chan Movie 09: Arashi wo Yobu Mouretsu! Otona Teikoku no Gyakushuu

A wave of nostalgia sweeps across Japan when the 20th Century Expo opens, recreating the sights and comforts adults remember from their youth. Hiroshi and Misae Nohara become increasingly captivated by the past until, like countless other parents, they abandon the present and disappear into the attraction, leaving the children of Kasukabe on their own.

Behind the phenomenon is Yesterday Once More, a group determined to reject the 21st century and restore an idealized past. Shinnosuke and his friends fight to bring their families back, while Shin-chan must remind his parents that the uncertain future they can build together is worth more than any perfect memory.
