GUN FISH: The World of Fugu You Don't Know is a documentary about Japan's pufferfish food culture, distributed by KeyHolder Pictures and narrated by actor Takumi Saito. It opened nationwide on September 4 at Theatre Shinjuku in Tokyo and other locations, with a trailer and key visual already out under the catchphrase "Because it's poisonous, it's interesting." Director Wataru Uno, who spent 10 years planning his debut and shot 680 hours of footage, obtained a pufferfish handling registration in Osaka during production.

The film follows Yukari Nameki, a young chef taking the Tokyo pufferfish cooking license exam in 2017, and profiles chefs, researchers, fishermen, and distributors. It also covers the debate over legalizing pufferfish liver consumption, which is currently banned in Japan. Recent research showing that pufferfish fed non-toxic food do not become toxic has fueled a movement to allow liver sales, while opponents argue wild and farmed livers cannot be distinguished and that accidents would be fatal.

By the September 7 stage greeting, the framing had shifted from a single release to a possible series. Uno said part 2 and part 3 are possible and Saito said he hopes the story continues. Saito appeared in a fugu-inspired outfit made by his stylist, and said Uno's footage earned him the label "the most insane."
