Mariko Tanaka Hiroko Yakushimaru is an inventive mind at Hitachi Appliances who accidentally re-engineers a washing machine into a time-travel device. This surprising breakthrough sets the stage for a blend of science fiction and social satire, as the government quickly entrusts her with a mission that feels both urgent and bureaucratic: travel back in time to block the passage of a fictitious law that would prevent real estate from being used as collateral for loans. That policy, if enacted, could have helped avert the bursting of Japan’s asset-price bubble, a historical tremor whose shadow hangs over the film’s premise. The setup fuses technical curiosity with real-world consequences, inviting viewers to consider how policymakers’ choices echo through families and markets alike.
When Mariko’s contact is suddenly lost after she steps into the past, the state dispatches Isao Shimokawaji Hiroshi Abe from the Finance Ministry’s Emergency Response Bureau to mount a rescue mission. His charge is twofold: ensure the mission’s continuity and coax Mariko’s estranged daughter Mayumi Ryoko Hirosue back into the fold so she can join the investigation. Mayumi’s reluctant return anchors the story in personal stakes, as mother and daughter navigate distance, distrust, and the tantalizing possibility that the past might offer a chance to heal what time and policy have frayed. The narrative tension is seasoned with a wry sense of humor, as past-and-present collide in ways that reveal bureaucratic fragility and the stubborn humanity that underpins genuine problem-solving. A running gag—other ministry officials who tested the time machine ending up with faded socks instead of usable data—keeps the mood light while underscoring the unpredictable quirks of time travel.
The film pays affectionate attention to everyday details, using small sight gags to illuminate the logistics of a world that straddles two eras. Notably, audiences get a playful nod to Tokyo’s everyday infrastructure through familiar electronic turnstiles and other familiar features, which become humorous touchpoints rather than mere backdrop. This gentle humor broadens the film’s appeal, inviting viewers to smile at the absurdities of trying to bend time without losing sight of ordinary life.
Beyond the central trio, the story unfolds with a colorful supporting cast that enriches the texture of the world. Kazue Fukiishi portrays Kaoru Miyazaki, adding a further dimension to the ensemble with a grounded, human presence. The movie also features Masatô Ibu and Gekidan Hitori in supporting roles, bringing their distinct personalities to the evolving dynamic between science, policy, and family. The film makes room for memorable cameos from celebrities who rose to prominence in Japan in the early 90s, appearing as younger versions of themselves: Ai Iijima, Naoko Iijima, Akiko Yagi, and Ruy Ramos. While they insert a delightful nostalgic flavor, their appearances serve the broader theme of time’s restless march and the way culture, fame, and memory intersect with historical moments.
Ultimately, the movie treats its premise with a steady, readable clarity, balancing explanation with character-driven moments. It presents a world where innovation can spark progress, but policy decisions require care, and personal relationships can be just as pivotal as any calculation. The friendship between a mother and daughter, the tug-of-war between ambition and responsibility, and the playful sunlit humor that comes from watching a time-travel device tinker with everyday life all coalesce into a thoughtful, entertaining experience. The film doesn’t sermonize; it invites reflection through humor, warmth, and a keen eye for the small details that make time travel both possible and surprisingly human.
