Plot
The film opens in the late 1990s at a boys' high school in a quiet town in Saitama, with a long empty summer ahead. A new young teacher, Sakuma, is hired to advise the swimming club and announces she will start a synchronized swimming team. Suzuki (Satoshi Tsumabuki), a good-natured boy with more enthusiasm than talent, signs up immediately for the transparent reason that he wants to get close to her. Behind him drift in four classmates: Sato (Hiroshi Tamaki), a failed basketball player with a giant afro; Ohta (Akifumi Miura), a muscle-obsessed fitness fanatic; Kanazawa (Kōen Kondō), a math-obsessed worrier; and Saotome (Takatoshi Kaneko), a quiet boy who harbors a crush on Sato and joins for his own reasons.
The premise collapses at once. Sakuma discovers she is pregnant and takes leave, abandoning the club with no coach, no girls, and no credibility. The five boys are left doing synchronized swimming in front of jeering schoolmates, an image so absurd that even they struggle to justify it. Suzuki refuses to quit, and the film's engine becomes the slow, fumbling conversion of five uncoordinated teenagers into something like a team, with the school festival as the deadline and the whole student body as a skeptical audience.
Their search for instruction leads them to Isomura (Naoto Takenaka), a trainer at a local aquarium who tricks the boys into believing he will coach them, using them as free labor hauling buckets and scrubbing tanks. His deadpan exploitation of their eagerness is the film's comic centerpiece in its middle stretch, and it eventually turns: he grows genuinely fond of the boys and starts teaching them in earnest, treating their ridiculous project with the seriousness of a professional. The boys also study a performing dolphin at the aquarium with scholarly devotion, and build their festival plans around the idea that a dolphin will leap alongside their routine.
Progress comes in increments. The boys negotiate choreography, costumes, and the logistics of filling a pool with only five bodies. They endure mockery, minor injuries, and the icy condescension of a nearby girls' team whose polished professionalism throws their flailing into relief. Saotome's crush on Sato is handled without cruelty: the film normalizes it rather than milking it, and the team absorbs him without ever making him the punchline. Slowly, the gags of synchronized failure give way to genuine improvement, and the boys begin to look, improbably, like a team.
The finale is the school festival performance, staged as a full-scale aquatic spectacle and it is the scene the film exists for. The pool is packed, the crowd arrives expecting a joke, and the boys take their positions. The routine, set to the pop standard "Gakuen Tengoku" ("School Paradise"), unfolds with tens of boys dancing in and out of the water, towers rising and collapsing, and the choreography the team spent a summer bleeding for finally paying off in front of everyone who laughed at them. At the worst possible moment, Suzuki's trunks come off in the water, stranding him at the base of the human tower with nothing to wear. Shizuko, the girl he has been courting all summer, throws him a handmade pair with "LOVE" sewn into the waistband. He puts them on, climbs the tower, and strikes the final pose to thunderous applause. The dolphin, needless to say, never shows up; the boys do not need it. The performance ends, the swim club is revived, and younger students take up the routine the seniors leave behind.
An epilogue follows the boys into the future: Suzuki goes to a university in Tokyo and keeps a long-distance romance going with Shizuko, Sato retakes his exams and teaches water aerobics to housewives, and Saotome becomes a high school teacher.
Characters
Suzuki (Satoshi Tsumabuki) is the believer, the boy whose enthusiasm permanently outruns his ability. He joins for the teacher but stays for the team, and his willingness to commit fully to a ridiculous idea is why anyone follows him. It was Tsumabuki's breakthrough role.
Sato (Hiroshi Tamaki) is the deadpan slacker with the afro, a washed-out basketball player who drifts in and gradually becomes the team's backbone and the object of Saotome's affection.
Ohta (Akifumi Miura) is the muscle-bound fitness obsessive who treats synchronized swimming as another training regimen, and Kanazawa (Kōen Kondō) is the anxious math geek who worries about everything, including the physics of a human tower.
Saotome (Takatoshi Kaneko) is the quiet gay member whose crush on Sato is played with warmth instead of mockery, one of the film's more quietly progressive choices.
Isomura (Naoto Takenaka), the aquarium trainer, is the film's great supporting character: a con man who cons his way into caring, and whose deadpan clowning keeps the middle of the film alive.
Interpretations and controversies
The film has little controversy attached. Critics have noted its unusually kind treatment of Saotome, normalizing rather than ridiculing his sexuality, which was uncommon for a mainstream Japanese comedy of 2001. The film's deeper reading, offered by several reviewers, is the dignity of doing something absurd with total commitment: the festival crowd's conversion from laughter to applause is the thesis performed rather than stated.
Sequels, prequels, and universe
Waterboys was successful enough to spawn a Fuji TV drama series that ran two seasons from 2003 to 2004, and a theatrical sequel, Waterboys 2, directed by Yuji Sato in 2004. Yaguchi went on to direct Happy Flight (2008).
The 2001 film
The film follows the Tadano High School swim club, down to a single member, third-year student Suzuki. When the young teacher Sakuma becomes club adviser, membership jumps to about 30 boys drawn by her looks, but she announces that the club will do synchronized swimming rather than competitive swimming, and nearly everyone quits. Five boys remain, and they reluctantly train for a performance at the school festival, aided by an eccentric dolphin trainer.1 • 7
The premise came from a real event. The swim club of Saitama Prefectural Kawagoe High School, a boys' school, had performed men's synchronized swimming as a school-festival attraction since the mid-1980s, and by the school's year 2000 festival the performance drew an audience of 20,000 people.3 • 8 • 9 Producer Daisuke Sekiguchi has said the project began after he saw a News Station television feature on the club's performance, and he developed the idea with Altamira Pictures' Masashi Masui before Yaguchi was chosen as director.10
Yaguchi's involvement. Yaguchi at first turned the offer down, imagining a gag routine of boys in makeup and women's swimsuits, and agreed only after being shown footage of the Kawagoe students' actual performance.11 He did not visit Kawagoe High for research; producer Masashi Masui has noted that Yaguchi worked from the news footage alone and developed the screenplay from his own ideas.12 The 28 actors playing the high schoolers went through a month-long swimming and synchronized swimming training camp before filming.3
The film opened on September 15, 2001 and reached third place in the national weekend box office in its first weekend, a strong result for a small-scale release from a small main theater.1 • 13 It became a hit through word of mouth, and the franchise expansion that followed, including the drama versions, made it a spark for the Japanese film boom of the 2000s.9 It was nominated for eight Japan Academy Prizes and won the award for Best Music.6 The cast also became a launching point: Tsumabuki, Tamaki, and other young actors went on to stardom, and the film established Yaguchi as a popular director.4
The television dramas
Fuji Television extended the property into television with three productions in quick succession.5
- Waterboys (2003): a serial drama starring Takayuki Yamada, with Mori Shuta (森山未來) and Eita among the cast; it averaged a 16.0% household rating in the Kanto region (Video Research measurement).2
- Waterboys 2 (2004): a new story set at Himeno High School, a former girls' school that had begun admitting boys three years earlier, following 32 boys devoted to synchronized swimming; it starred Hayato Ichihara with Satomi Ishihara as the heroine and averaged 16.8% in the Kanto region.2 • 14
- Waterboys 2005 Summer (2005): a two-night special drama.5
The productions were filmed in summer settings that emphasized the Japanese season: the 2003 drama mainly in Yamanashi Prefecture and Waterboys 2 mainly in western Shizuoka Prefecture, while the film was shot mainly in central Shizuoka.5
Waterboys 2027
On October 16, 2026, Fuji Television announced Waterboys 2027, a completely new serial drama to begin in July 2027, 26 years after the film's release and 22 years after the last television production.2 • 5 The new series is set in 2027 and follows aimless boys at an old pool who encounter synchronized swimming, which the production notes is now formally called artistic swimming, though the show keeps the on-screen shorthand "shinkuro" (シンクロ).2 The staff include screenwriters Shota Ganyan (我人祥太) and Hiroyuki Komine, music by Naoki Sato, producer Yusaku Tashiro, and directors including Kazunari Hoshino; the original film's director and screenwriter credit is listed as Yaguchi.2
The revival sits within a wider wave of Fuji TV revivals of past hits, including 101st Marriage Proposal, GTO, Emergency Room 24 Hours, and the Bayside Shakedown films, and commentary has noted both the built-in name recognition of such revivals and doubts about whether the once-novel premise of boys doing synchronized swimming still feels fresh.5 • 15
Legacy
The film's success created a recognizable template: Yaguchi followed it with Swing Girls (2004), built on a similar mismatch of unlikely students and an unlikely pursuit, and the two films are regularly paired as the signature works of his comic style.10 The Kawagoe High performance that inspired the story has continued as a festival attraction, drawing crowds large enough that visitors line up an hour before showtime.16
