Setting and premise

The film posits an alternate near-future in which Japan's economic power has drawn millions of immigrants who live in shanty communities around the urban centers, nicknamed Yen Town by the xenophobic Japanese residents⁷. The name is a play on words: the immigrants' "Yen Town" (円都) is a homonym of a phrase whose alternative kanji spelling translates to "Yen Thieves" (円盗), which is how the Japanese population derisively labels the newcomers⁷^•⁵. Dialogue shifts among Japanese, English, and Mandarin, reflecting the hybrid, stateless world of the immigrant community⁶^•².

Plot

The story is told through the eyes of Ageha (Ayumi Ito), a young girl named after the Japanese word for the swallowtail butterfly⁷. After her mother, a Chinese immigrant, is found dead, Ageha is taken in by Glico (Chara), a prostitute with a swallowtail tattoo who dreams of becoming a singer, and joins a close-knit band of illegal immigrants who commit petty crimes and scavenge through landfills to survive⁷^•⁸.

The cassette and the scam. After Ageha is attacked by a client, the group kills him in her defense and finds a cassette tape sutured into the lining of his stomach⁷^•⁴. The tape, a recording of Frank Sinatra's "My Way" that becomes a musical motif, carries a hidden electronic signal that fools automatic teller machines into treating disguised 1,000-yen notes as 10,000-yen notes, so each deposit returns ten notes and a 9,000-yen profit⁷. Using the proceeds, the group opens a nightclub and launches the Yen Town Band, with Glico as lead singer; the band becomes a national sensation, and Glico's fame strains her relationship with Feihong (Hiroshi Mikami)⁷. Meanwhile factions of the underworld hunt for the tape, led by Rio Ryanki (Yosuke Eguchi), the ferocious head of the Shanghai crime syndicate operating in Yen Town⁷.

Production and music

Iwai, already known for Love Letter (1995), made the film with a production budget of about 5 million dollars⁹. It was produced by the Swallowtail Production Committee, a consortium of Uruonsha, Pony Canyon, Japan Herald Films, Ace Pictures, and Fuji Television, with Rockwell Eyes as the production company and distribution by Japan Herald Films and Ace Pictures¹. Noboru Shinoda was the cinematographer and Yohei Taneda the art director¹.

The film's music proved as influential as the film itself. Takeshi Kobayashi composed the score, and the fictional band YEN TOWN BAND, fronted on screen by Chara's Glico, released its songs for real, and they became major hits⁴. The theme song is "Swallowtail Butterfly ~あいのうた~"¹.

Style and reception

Iwai shot the film with abundant handheld photography and edited it with freeze frames and jump cuts, giving it a restless, music-video-inflected energy; Film at Lincoln Center describes it as occupying "pretty much the same cultural territory in Japan that Pulp Fiction occupies in America"⁷^•¹⁰. The film was a hit among young adults in Japan and across East Asia⁷. At the 20th Japan Academy Prize in 1997 it won Outstanding Picture, Outstanding Lead Actress for Chara, Outstanding Supporting Actress and Newcomer of the Year for Ayumi Ito, and technical prizes for cinematography, lighting, art direction, and sound recording⁴. On IMDb it holds a 7.5/10 rating from about 5,000 votes¹¹, and Rotten Tomatoes lists an 89% Tomatometer from two critic reviews¹².

Scholarly criticism. Academic responses have been more divided. Eric Cazdyn, a scholar of Japanese film, argued that the film's "gratuitous aesthetic gestures" preclude engagement with its own questions about attitudes toward foreigners in Japan's labor economy, and Mika Ko, author of Japanese Cinema and Otherness, called it an example of "cosmetic multiculturalism" that fetishizes attractive immigrant stories without examining their lived experiences in depth⁷^•¹³. Koichi Iwabuchi, writing with Yomota, Cazdyn, and Gerow, argued that despite its attempt to represent multicultural chaos in Japan, the film is strikingly absent of any "real" encounter between Japanese citizens and the Asians it depicts¹⁴.

Legacy and 30th anniversary

More than fifteen years after its release, reviewers familiar with late-1990s Japanese cinema still recognized the film's palpable influence, and it is regarded as a precursor to Japan's later global pop-cultural boom⁷. For the 30th anniversary of the 1996 release, a 4K remastered version with Dolby Atmos sound, supervised by Iwai, received a theatrical re-release in Japan on September 4, 2026, distributed by Pony Canyon⁴^•³.
