🍲 The Short Answer
Sumo wrestlers eat chanko nabe — a large, protein-rich hot pot stew — as their staple meal. They eat it twice a day: a massive lunch after morning training, and dinner in the evening. They skip breakfast entirely. The two-meal system, combined with sleeping after lunch, is deliberately designed to maximise calorie retention and weight gain. Top wrestlers consume an estimated 5,000 to 8,000 calories per day.
⏰ A Wrestler's Eating Day
The sumo eating schedule is inseparable from the training schedule. Understanding the day explains the diet.
🔥 How Many Calories?
Estimates vary widely, and actual intake differs by division, body size, and individual. These are rough illustrative figures — not clinical measurements:
Note: These are broad estimates from reported data. Individual variation is significant. Body weight, training intensity, and metabolic rate all affect actual intake.
Where the Calories Come From
- Chanko nabe — the bulk: protein, fat, carbs from broth, protein, and vegetables
- Rice — multiple servings per meal, a core carbohydrate source
- Side dishes — fried foods, pickles, eggs, depending on stable
- Beer / alcohol — traditional at dinner in some stables; significant caloric contribution
- Snacks after dinner — some wrestlers eat ramen, ice cream, or other foods late at night
🥘 Chanko Nabe — The Sumo Staple
Chanko nabe (ちゃんこ鍋) literally means "stable master's hot pot" — chan is an informal word for the stable master, and ko refers to the wrestlers. It's not a single recipe — it's a format. Every stable has its own house version, passed down through generations.
Why Chicken More Than Beef?
You'll often hear that chanko nabe traditionally uses chicken rather than beef or pork — and there's a superstitious logic behind it. In sumo, touching the ground with anything other than your feet means you lose. Cows and pigs walk on four legs, touching the ground with their knees. Chickens walk on two legs. For wrestlers who spend their days trying to stay on two feet, eating two-legged animals was considered auspicious. Whether or not wrestlers still believe this, chicken remains the dominant protein in many stables.

One of Japan's most-watched sumo YouTube channels belongs to Futagoyama Stable — the stable featured throughout this site. Their channel, 二子山部屋 sumo food, documents real stable life: wrestlers cooking chanko nabe from scratch, eating together, and living the sumo daily routine. Over 490,000 subscribers and 200 million total views, with English subtitles.
🏆 Does Rank Affect What You Eat?
Yes — significantly. The stable hierarchy governs not just training, but the entire eating culture.
- Eat first at every meal
- Get the best cuts and largest portions
- May eat in a separate room or at the head of the table
- Served by junior wrestlers
- More freedom in their diet choices
- May eat out at restaurants
- Cook all the meals for the stable
- Eat last — after seniors are finished
- Eat whatever is left in the pot
- Less variety and smaller effective portions early in career
- Learning to cook chanko is part of sumo training
- Rising through ranks = better food access
This hierarchy isn't just tradition — it's a motivational structure. Getting promoted means eating better. For a hungry 18-year-old in Jonokuchi, watching the Makuuchi wrestlers eat first every day is a daily reminder of what advancement looks like in concrete, tangible terms.
⚖️ What Happens When They Retire?
One of the most misunderstood aspects of sumo is what happens to wrestlers' bodies after retirement. Because the weight gain is largely driven by the two-meal system, afternoon napping, and intense caloric intake rather than pure fat accumulation — and because active wrestlers do train intensively — many wrestlers lose significant weight relatively quickly after retiring.
Former wrestlers who switch to a normal eating pattern (three meals, no post-lunch sleep, lower caloric intake) and remain active often return to something closer to a typical body weight. The bodies of sumo wrestlers are not simply obese — they carry substantial muscle mass beneath the surface layer of fat. The sumo physique is the result of a very specific, deliberately maintained system.
After retirement, many wrestlers open chanko nabe restaurants — a long tradition in the sumo world. The Ryogoku area of Tokyo near the main sumo arena is packed with chanko restaurants run by retired wrestlers.
