Plot

In a 21st-century Japan whose population has aged beyond what its care system can handle, the Ministry of Public Welfare launches the "Z Project": a fully automated nursing bed, Z-001, intended to care for solitary elderly people at home.² The bed runs on a miniature nuclear reactor and carries a built-in computer that handles meals, bathing, waste disposal, and even entertainment such as television, radio, telephone, and audio equipment, on the promise of freeing the patient from loneliness.²

The first test subject is Mr. Takazawa, an 87-year-old bedridden widower who had been cared for at home by Haruko, a student nurse doing volunteer work.³^•² At the machine's public presentation Haruko watches Takazawa washed, changed, fed, and exercised entirely by the device, and finds the sight of him bound up in the machine painful to watch.² Back at school she discovers her name spelled out across a wall of computers, sneaks into the welfare center to reach him, and, as if answering her, Z-001 suddenly begins to run wild.²

The runaway bed carries Takazawa out into the city, transforming as it goes, and fights a pitched battle with a combat robot developed for military use.⁵^•² Haruko and a ward of elderly hospital patients who are skilled computer hackers join the pursuit to rescue him.⁵^•¹ Takazawa longs for his late wife Haru, and the machine, imitating her voice, takes on the role of wife and protector; his desire to revisit Kamakura, where he spent happy days with her, drives its revolt.⁶ A subplot involving the military's interest in the Z-001's chip runs beneath this more personal story.⁶

Production

Otomo, riding the success of Akira (1988), limited himself on this project to scripting and mechanical design rather than directing, working on a considerably smaller budget.¹ Character designs came from manga artist Hisashi Eguchi, and Kitakubo, who had earned praise from James Cameron and Quentin Tarantino for Blood: The Last Vampire, directed.² The animation staff included a group of then-young artists who later became leading figures in Japanese animation: Satoshi Kon, Kōji Kamiyama, Kazuya Kise, Tetsuya Nishio colleague Toshiyuki Inoue, Hideaki Anno collaborator Kazuya Tsurumaki, and Kōji Morimoto, among others.² The Science Fiction Encyclopedia credits Kon specifically as a set designer on the film, an early credit in his career.¹ The music was composed by Bun Itakura, working with Miwako Ogawa, formerly of the band Chakra.²

Themes and reception

The film is a satire of a society that hands the problems of aging and caregiving over to technology. The Japan Society's review notes that it places the camp, overblown conventions of the robot-anime genre inside a serious moral question: whether a machine devoid of compassion can give a human being the care he needs.⁶ The title itself plays on this collision, since rōjin simply means an elderly person, while the "Z" evokes giant-robot shows such as Mazinger Z.⁶ The Science Fiction Encyclopedia calls it the first anime to tackle the issue of Japan's "greying population", and a satire of government boondoggles and heartless yuppies.¹

Critics have repeatedly connected the film to Otomo's Akira. Roger Ebert, reviewing the 1996 American release, described it as a "quite different, but equally savage, satire about healthcare for the aged in the 21st century" and noted how its storyboarded, comic-book-like visual invention compensates for animation that is economical by Hollywood standards.⁷ Reviewers have also observed that its subject has not dated: the ratio of working-age Japanese to retirees, almost six to one in 1990, was projected to fall to nearly two to one by 2025, and commentators writing decades after release note that the film's concerns about elder care remain unresolved.⁶^•⁸ On Rotten Tomatoes the film holds a Tomatometer score of 60 percent from three reviews, with more than 500 audience ratings.⁹

Legacy

The film is remembered both as a comedic action piece and as an unusually early piece of social commentary on robotics in elder care, a theme later taken up by real research programs in Japan and elsewhere.⁶ Its staff list has also given it a lasting place in animation history, since many of the young animators who worked on it went on to direct or lead major projects of their own.² A remaster in the HDCAM SR high-definition format with newly recorded 5.1-channel surround sound was later produced, and the film has continued to be re-released on home video.²
