‘Sumo: Spirit Weighs Nothing’ review: Cinematic, empathetic doc gets in the ring with Japan’s most iconic sport

Dir: Erik Shirai. Japan/US/Denmark/UK. 2026. 99mins

This is not the first documentary to shine a light on the highly insular world of sumo wrestling. But it may be the most revealing. It plays out not as a sports documentary but as a piece of cinematic anthropology, an attempt to understand a cultural ritual and the mindset of those who practice it.

A yearning, melancholic portrait of a ritualized sport 

In this, Sumo: Spirit Weighs Nothing is rather like Japanese-American director Shirai’s 2015 feature debut, The Birth of Sake. Both enter closed communities in which the search for perfection has been loaded with spiritual significance. At first, Shirai’s long gestating second feature appears rather seduced by this age-old sport’s ceremonial surface: after all, like bullfighting, it’s a highly codified and stylized form of brutality that lends itself to fetishization. Gradually, though, the human cost, the emotional fissures and the sheer physical toll of sumo are drawn out. This is an eminently cinematic feature that will next travel to London following a premiere in Telluride and a berth in Venice Spotlight; Disney plans to release the film in 2027.

Sumo: Spirit Weighs Nothing finds a way into this often misunderstood sport by focusing on three young, aspiring rikishi fighters who all belong to the ‘stable’ of 62-year-old sumo master Sakaigawa. Each one is introduced in elegant, calligraphic onscreen captions that list the wrestler’s name, age and weight. Each are given audience-friendly epithets. The oldest apprentice, 24-year-old Hiradoumi, is labelled ‘The Rising Star’, 19-year-old Yonezawaryou is ‘The Rookie’, while 15-year-old Kosei is dubbed ‘The Little Giant’. The latter provides one of many surprises for the uninitiated – because he’s far from overweight. Size and age aren’t everything, master Sakaigawa informs us in voice-over: it’s “the one with the strongest spirit who wins”. Parents get a look in too – in Kosei’s case, as fearful yet admiring spectators of their undersized son’s passionate vocation.

If Shirai’s absorbing, empathetic documentary is a kind of traditional Japanese Hoop Dreams, it’s one that learns from the understatement of its subjects who, in press conferences or in response to the director’s questions, answer in as few words as possible, sometimes even with silence. Is the film too elegant at times? It’s certainly beautifully shot, whether lingering in grainy, washed-out colour on the precise tying of a rikishi’s top-knot or projecting fluttering cherry blossom onto a fighter’s torso. It also details, in sepia-tinged black-and-white, the meticulous, geometrical banking up of the arakida clay and top level of sand of the dohyo sumo ring before each of the tournaments that measure out the sumo wrestler’s year, and give the documentary its seasonal structure. 

A fourth sumo fighter, 33-year-old reigning champion Terunofuji, is introduced slowly into the finely edited narrative, acting as a poignant ‘be careful what you wish for’ note. He’s a god among rikishi, a star who is huge, in every sense of the word, one who is constantly mobbed by fans – many of them young women. Yet his body is falling apart. For wrestlers, eating vast quantities of carbs and protein is a necessity, not a pleasure (Master Sakaigawa advises Kosei, who is struggling to bulk up, to keep rice cakes by his bed so he can go on snacking through the night). The internal organs, we learn, are put under huge strain; knees often buckle, diabetes and osteoarthritis are rife, and ten to twenty years are taken off the average lifespan. All this for a sport whose bouts can last all of five seconds.

This is a documentary about three young men’s hopes and dreams, but it’s also a yearning, melancholic portrait of a ritualized sport that is seeing fewer and fewer young recruits. It’s a mood delicately embraced by Rutger Hoedemaekers’s wistful soundtrack, which uses traditional Japanese instruments like the shinobue flute to underline the elegaic tone.
