Studio 4°C

• 1. Introduction

  ›

  Studio 4°C takes its name from a precise physical fact: four degrees Celsius is the temperature at which water reaches its greatest density. It is a quiet, scientific name for a studio that has spent decades pushing Japanese animation into territories few others dared to explore. Founded in 1986 by Eiko Tanaka and Kōji Morimoto, the Tokyo-based independent has produced feature films, original video animations, music videos, short films, and sequences for video games and commercials. What drives a studio to animate segments of The Animatrix, collaborate with Warner Bros. on a Batman anthology, and contribute shorts to the Halo universe - all while making avant-garde films that win prizes at festivals from Moscow to Montreal? The answer lies in how Studio 4°C chose to define independence from the very beginning.

• 2. Founding and Early Work

  ›

  Eiko Tanaka and Kōji Morimoto established Studio 4°C in 1986, positioning it from the start as an independent operation outside the major studio system. The studio's earliest feature-length ventures arrived in the mid-to-late 1990s. Memories, an anthology film, appeared in 1995. Noiseman Sound Insect and Eternal Family both followed in 1997 as original video animations. The action film Spriggan reached screens in 1998. During that same period the studio began producing music videos, including one for Ken Ishii titled "Extra" in 1996 and work for the UK band the Bluetones in 1998. Princess Arete, a fantasy feature, arrived in 2001. That year the studio also contributed animated segments to Kamikaze Girls and began working on video game cinematics, including sequences for Ace Combat 04: Shattered Skies. These early years established a pattern that would define Studio 4°C: a willingness to take on radically different projects in the same breath, moving between experimental shorts and mainstream genre films without settling into any single mode.

• 3. The Animatrix and Global Partnerships

  ›

  In 2003, a joint production with Warner Bros. placed Studio 4°C inside one of the most discussed animation projects of that decade. The studio created five of the short films that made up The Animatrix, an anthology tied to the Matrix film universe. Their segments included "Kid's Story," "The Second Renaissance," "Beyond," and "A Detective Story." The following year brought Mind Game, described as an avant-garde film, which won awards and signalled that the studio's ambitions extended well beyond franchise work. That dual identity - trusted collaborator on major American intellectual properties and home to challenging, award-winning independent cinema - became the hallmark of how Studio 4°C operated through the 2000s. Batman: Gotham Knight, an OVA collection tied to the Dark Knight universe, arrived in 2008, again in collaboration with Warner Bros. The studio also produced the animated feature for DC's Justice League: The Flashpoint Paradox in 2013, as well as the DC Universe animated short for Green Lantern: Emerald Knights in 2011. The Warner Bros. relationship extended to television as well, with ThunderCats in 2011 co-produced between Studio 4°C and Warner Bros. Animation, alongside The Answer Studio and Mook Animation.

• 4. Tekkon Kinkreet and Festival Recognition

  ›

  Tekkon Kinkreet, released in 2006, brought Studio 4°C its most concentrated burst of international recognition up to that point. The film won six awards, among them Best Animated Film at Fantasia 2007, the Lancia Platinum Grand Prize at the Future Film Festival, and the Japan Academy Prize for Animation of the Year. It was also submitted as Japan's entry in the Animated Feature Film category at the Academy Awards in the United States in 2007. Three years later, First Squad: The Moment of Truth, a co-production with Russian studio Ligalize - whose earlier music video "Pervyi Otryad" ("First Squad") Studio 4°C had animated in 2005 - was awarded at the Moscow International Film Festival. These recognitions at festivals across Europe, North America, and Japan confirmed that Studio 4°C's work circulated in a genuinely international critical conversation, not simply within the Japanese animation market.

• 5. The Anthology Experiments

  ›

  Genius Party, released on the 7th of July 2007, gathered seven short films into a single theatrical anthology, each by a different director working under the Studio 4°C umbrella. The following February, Genius Party Beyond assembled five additional short films in a second volume. These two collections represented the studio's most concentrated experiment in anthology form, giving individual directors space to pursue divergent visual approaches within a single release. The Sweat Punch series, five short films produced between 2001 and 2002 and collected on DVD in 2007, had preceded them: the titles included "Professor Dan Petory's Blues," "End of the World," "Comedy," "Beyond," and "Junk Town." Amazing Nuts!, four short films released exclusively on DVD in 2006 as a collaboration with Rhythm Zone, followed a similar model. The anthology format let Studio 4°C act almost as a distributed workshop - one where experimental approaches could coexist without requiring any single film to carry commercial weight alone. This structure would surface again in February 2010, when the studio contributed two segments, "Origins" and "The Babysitter," to Halo Legends.

• 6. Breadth of Collaboration

  ›

  A Nike commercial featuring LeBron James, titled "In Chamber of Fear (Self Doubt)," appeared in 2004 - the same year the studio produced the animated segment for the video game Ape Escape: Pumped and Primed. A Toyota campaign called PES-peace eco smile generated a series of shorts in 2012, and a spin-off short titled "Drive Your Heart" followed in 2013 as an advertisement for the same brand. The studio animated sequences for video games ranging from Rogue Galaxy in 2005 to Catherine in 2011 to the Doodle Champion Island Games in 2021. Music video work continued across the 2000s, including animated clips for Japanese pop star Ayumi Hamasaki in 2002 and two separate videos for Hikaru Utada in 2005 and 2006, the latter tied to the Square Enix game Kingdom Hearts II. A short titled My Last Day, created in 2011 in association with The JESUS Film Project, Brethren Entertainment, and director Barry Cook, demonstrated that even faith-based media projects fell within the studio's scope. A TV special, Ballmastrz: Rubicon, appeared in 2023. The studio's scheduled future work includes the animated feature All You Need Is Kill, listed for 2026, and an untitled SWAT Kats: Revolution project co-produced with Warner Bros. Animation and Toonz Entertainment.

• 7. Children of the Sea and Recent Features

  ›

  Children of the Sea, released in 2019, continued Studio 4°C's long-running engagement with feature animation based on acclaimed source material. Poupelle of Chimney Town followed in 2020. Fortune Favors Lady Nikuko arrived in 2021, and Mutafukaz, a 2017 co-production with France's Ankama Animations, extended the studio's international co-production record beyond the American studios it had worked with most frequently. The Berserk: Golden Age Arc trilogy, spread across 2012 and 2013 with three entries - The Egg of the King, The Battle for Doldrey, and The Advent - showed the studio taking on long-form adaptation of a major manga property across multiple theatrical films. Harmony, released in 2015 as part of the Project Itoh trilogy, placed Studio 4°C in a three-film collaboration commemorating science fiction author Project Itoh. ChaO, listed for 2025, marks the most recent completed feature in the studio's catalogue - a record that by then stretched across nearly four decades and an unusually wide range of formats, partners, and subjects.
