Plot and characters

The story follows Hideo Suzuki (鈴木英雄), a 35-year-old unsuccessful manga artist working as an assistant to a more successful peer. His one distinguishing skill is a sporting shotgun license maintained through years of clay pigeon shooting. As a mysterious new virus spreads across Japan, his girlfriend Tekko becomes infected and turns into a zombie, and Hideo flees his workplace with his shotgun, sharing a taxi by chance with the high school student Hiromi and escaping from Tokyo toward Yamanashi.⁶

The infected humans are called ZQN (ゾキュン), zombie-like creatures that attack the uninfected. Hiromi, played by Kasumi Arimura, has been bitten by a toothless infant ZQN, leaving her in a half-ZQN state: human enough to communicate, infected enough to share the creatures' instincts. Masami Nagasawa plays Yabu (藪), a former nurse the pair meets at a survivor refuge in an outlet mall who acts with clear purpose and sees Hiromi's half-ZQN blood as potentially containing an antibody.⁷

Production

Director Shinsuke Sato, born in Hiroshima Prefecture in 1970, had already made his name with live-action manga adaptations including the GANTZ films and the Library Wars series, and he brought the same team to this film: screenplay by Akiko Nogi, cinematography by Taro Kawazu, music by Nima Fakhrara, and special makeup supervised by Kakusei Fujiwara.⁸^•⁶ The film was produced by Toho with a consortium of partners including avex pictures, Shogakukan, Dentsu, WOWOW, and Hakuhodo DY Media Partners.⁹

Large-scale overseas filming. The production spent its budget on location work in Korea and collaborated with Korean staff on the large-scale special effects and special makeup, an approach reviewers credited with giving the zombie action a scale unusual for Japanese genre cinema.⁵^•¹⁰ The special effects team included special effects director Makoto Kamiya and CG director Jun Doi.⁵

Reception and awards

Before its Japanese release the film screened at several international fantastic film festivals. At the 48th Sitges-Catalonia International Film Festival it won the competition section's audience award and the award for best special effects; at the 36th Porto International Film Festival it took the audience award and the Oriental Express special award; and at the Brussels International Fantastic Film Festival it won the Golden Raven, the top prize of the international competition. Counting these, the film took five awards across the three festivals commonly counted among the world's major fantastic film festivals.⁴^•⁵ It also won the Midnighters section audience award at SXSW in March 2016.⁵

Box office. The film earned over 1.6 billion yen, ranking 21st among Japanese films released in 2016 according to the Eiren distribution tally.³^•⁴

Japanese critics received the film as a breakthrough for a genre long considered a weak point of domestic cinema. Reviewers for Cinema Today praised its unflinching gore, its shopping-mall siege sequences as homage to George A. Romero, and the casting of Oizumi as the hapless hero, with one writer calling it a masterpiece that would remain in world zombie film history.¹⁰ The film critic Tetsuaki Matsue, writing for Real Sound, highlighted the film's long single take early on, in which Hideo senses something wrong outside and the ZQN multiply until the world has flipped over, and argued that by following the newer virus-infection rule of zombie cinema established by works such as Resident Evil and 28 Days Later, the film avoided the parodic register that had constrained earlier Japanese zombie films.¹¹

Legacy

The film established Sato as a leading director of live-action manga adaptations and became a reference point for Japanese zombie cinema. The underlying manga ran to 22 volumes and 265 chapters in its electronic complete edition.¹² In later years the title circulated internationally on streaming platforms including Crunchyroll, and it was among the Japanese properties pitched to North American producers for potential series or remake adaptation.¹³^•¹⁴
