You see them on screen—massive, immovable giants clashing in a ring of sand. It’s breathtaking. But there’s a dark side to the life expectancy of sumo wrestlers that doesn't usually make it into the highlight reels.
While the average Japanese man can expect to live well into his 80s, professional sumo wrestlers are often looking at a lifespan that ends in their 60s. Sometimes even earlier. Honestly, it’s a staggering gap. We’re talking about a twenty-year difference compared to their neighbors.
Why? It’s complicated. It’s not just "being fat." It’s a systemic, centuries-old lifestyle designed to create the ultimate athlete at the expense of the human being.
Why the Life Expectancy of Sumo Wrestlers Is So Low
The math is pretty grim. If you look at the data, the average life expectancy of sumo wrestlers sits somewhere between 60 and 65 years. In a country like Japan, which literally leads the world in longevity, this is a glaring anomaly.
Take Taro Akebono, for instance. He was a legend—the first foreign-born Yokozuna. He died in 2024 at just 54 years old. Heart failure. Then there’s Hibikiryu, who died at 28. Granted, his was a freak accident in the ring, but it sparked a massive conversation about how these men are treated.
The primary culprits are exactly what you’d expect:
- Cardiovascular disease
- Type 2 diabetes
- Chronic hypertension
Basically, their bodies are under constant siege. You’ve got 300 to 400 pounds of mass pressing down on a human heart every single second of the day. Even when they sleep.

The Myth of the "Healthy Fat" Athlete
There is this idea floating around that sumo wrestlers are "fit but fat." To a degree, that’s true—while they are active.
Studies, including some published in the Journal of the Endocrine Society, show that as long as a wrestler is training five hours a day, their body handles the weight surprisingly well. Their intense exercise keeps their visceral fat (the dangerous stuff around organs) relatively low. Their fat is mostly subcutaneous—stored just under the skin.
But here’s the kicker: the moment they stop training, that protection vanishes.
Most wrestlers retire in their 30s. If they don't immediately drop 100 pounds, their metabolism, which has been tuned to a 10,000-calorie-a-day intake, starts destroying them. The visceral fat piles up. The insulin resistance spikes. The heart, already thickened from years of pumping blood through a massive frame, starts to give out.
The Chanko-Nabe Trap and 10,000 Calories
If you’ve ever seen a "day in the life" video of a sumo stable (a heya), you know about Chanko-Nabe. It’s actually a pretty healthy stew—loaded with chicken, fish, tofu, and mountains of bok choy.
The problem isn't what they eat. It's how much.

Wrestlers skip breakfast to train on an empty stomach. This slows down their metabolism. Then, they gorge on two massive meals and go straight to sleep. It’s a scientifically perfected method for weight gain. They aren't just eating for fuel; they are eating to become a "wall."
I’ve read accounts from retired wrestlers like Anatoly Mikhakhanov, who reached over 600 pounds. He talked about the pressure to keep eating even when you're full. Senior stablemates would just keep piling rice into your bowl. You can't say no. It's a hierarchy.
The Painkiller Problem
We also have to talk about the physical toll. These guys aren't just heavy; they are explosive. The impact of a tachi-ai (the initial charge) is often compared to a car crash.
To keep fighting through torn ACLs and broken bones, many wrestlers rely heavily on painkillers. Former wrestlers have pointed to this as a major factor in kidney failure and heart issues later in life. In the world of sumo, sitting out means losing your rank. If you lose your rank, you lose your salary.
So, you fight. You take the pills. You eat the stew. You hope your heart holds out.
Is Anything Changing?
The Japan Sumo Association (JSA) isn't totally blind to this. They've started implementing more medical checks. There's more talk about weight management for retirees.

But tradition is a heavy weight in Japan.
Some fans and officials argue that a weight limit would ruin the sport’s "soul." Others, like the legendary Chiyonofuji, showed that you could be a champion with more muscle and less bulk (though he still died at 61 from pancreatic cancer).
Modern wrestlers are starting to take it more seriously. You’ll see guys like Ishiura who focused on strength training and a more "modern" athletic diet. But for every one of those, there are a dozen young men being told to "just get bigger."
What We Can Learn From the Sumo Lifestyle
Most of us aren't trying to push 400 pounds, but the life expectancy of sumo wrestlers offers a pretty stark lesson in metabolic health.
- Visceral fat is the real enemy. It’s not about the number on the scale as much as where that weight is sitting.
- The "Stop" is dangerous. Transition periods—like retiring or stopping a sport—are when the most damage happens. You can't keep the diet if you lose the activity.
- The "Sumo Diet" works (for gaining weight). If you skip breakfast, eat huge meals, and nap immediately, you will gain weight. If that's not your goal, do the opposite.
If you’re interested in longevity, the best thing you can do is look at what a sumo wrestler does and do the inverse. Eat consistently throughout the day. Prioritize cardiovascular health. Don't let your weight outpace your heart's ability to support it.
The rikishi are incredible athletes, but they are living a tragedy of tradition. Their shortened lives are the price paid for a few minutes of glory in the dohyo.
Actionable Insights for Longevity:
- Prioritize heart health: If you carry extra weight, regular cardio isn't optional; it's a requirement to help your heart handle the load.
- Manage the transition: If you’re an athlete moving into a less active phase of life, your caloric intake must drop immediately to avoid rapid visceral fat accumulation.
- Monitor the "hidden" fat: Regular blood work and waist-to-hip ratio checks are better indicators of health than simple BMI, especially for muscular individuals.
