A Heavy Toll: Shirai’s Artful Take on the Body Shattering Sumo Tradition Honors the Form
Gaining access to Japan’s most traditional and one of their most gruelling sports, Sumo: Spirit Weighs Nothing flirts with revolutionary documentary ideas surrounding the age-old practice of sumo wrestling. Filmmaker Erik Shirai, usually found in the camera department, showcases his keen eye here with a beautifully shot and composed examination of the sacrifices needed to become a Yokozuna (Grand Champion). While some of the introspective swings run out of steam, the subject and direction often make this year in the life type docu soar.
We start in the classic sumo wrestling ring in the “stable” of sumo master Sakaigawa as a host of young hopefuls attending “sumo school” march definitely round, shoulder to shoulder, in unison. There is an early idea of the deeply respected, religiously rooted sport holding great spiritual significance. There is a code of conduct, a harsh burden to bear both through body and mind but equally, only the strongest can overcome. This is largely viewed through the eyes of the stable’s Rikishi fighters, 24 year old Hiradoumi, “The Rising Star”, 19 year-old Yonezawaryu, “The Rookie” and 15 year-old Kosei, “The Little Giant”. Each athlete is at a critical stage in their career and must sacrifice their lives and as we find out, most likely their health to achieve Yokozuna status. This is currently held by the depleting world champ, 33 year-old Terunofuji who is dealing with countless later stage injuries. Each person is a layered mirror unto themselves which creates a fascinating insight into the unique almost reverse pro athlete world of the sumo.
We get to know each endearing and mostly very tired character intimately despite the economical runtime. There’s great pleasure to be had in watching the harsh stable master tick off the small Kosei because he’s not eating quick enough or simply just not enough. Sumos eat up to 10,000 calories each day to maintain their gigantic size but also must manage a level of muscular and balanced equated fitness to hold their own in the ring. Trying to keep this equilibrium brings major strain on the body’s vital organs as Hiradoumi regularly reminds us that committing to sumo knocks at least 10 maybe even 20 years off your life. There is a hierarchical structure based on status in the stable and tournament success relating to skill level and notoriety intended to keep the fighters in check. It’s not about the physical power, it’s all about the spirit.
Everything looks beautiful here and Shirai takes great care in telling these stories but the film occasionally falters when it uses tricks and somewhat contrived shots taking away from the gritty realism. This is evident in the men’s fleeting tales about the joy sumo brought them as children or the connections they may share with others in the stable. A sumos back acts as a projector for filmlike childhood memories and janky flashbacks haunt Yonezawaryu after he accidentally puts his best friend in hospital during a match. As the route to the top and back down through tournament to tournament wears on, the film just about runs out of steam but still comes out on top thanks to its electric early momentum.
The pain injections, diabetes and knee braces may fool you into thinking Sumo: Spirit Weighs Nothing is all about blood, grit and fights. But this is an admirably tender documentary that celebrates people with a stunning mental strength and appetite for success.
