Chankonabe — The Sumo Wrestler's Stew

Chankonabe (ちゃんこ鍋) is the protein- and vegetable-packed hot-pot stew that has fuelled every Japanese sumo stable for more than a century. It’s eaten twice a day, in quantities that would feed a normal family for a week, and it’s the single biggest reason rikishi can reach the 150–200 kg fighting weights the sport demands. At the Kyoto Sumoan show, a traditional chankonabe is served after the demonstration — one of the few places outside a Ryogoku specialist restaurant where you can taste the actual sumo-stable version.

Here is what the stew is, why it works, and what gets served at the show.

What “chankonabe” literally means

The word breaks into two parts:

• Chanko (ちゃんこ) — originally meant any food prepared by the stable’s chef (the oyakata or coach), regardless of dish. The etymology is affectionate: “chan” (ちゃん) is a familiar honorific for an elder brother or beloved relative, and “ko” (こ) means “child.” Together it suggests food the stable elders feed to the wrestlers-in-training.
• Nabe (鍋) — simply means “pot” or “hot-pot dish.”

So “chankonabe” specifically means “the hot-pot version of sumo-stable food.” Strictly, “chanko” on its own refers to any meal served at a stable, but the stew is so iconic that it has become synonymous with the word.

Why sumo wrestlers eat it

Rikishi in an active training stable typically consume 5,000 to 8,000 calories per day, and some reach 10,000 — more than double what a normal active adult eats. They train on an empty stomach each morning (a practice believed to stretch the body’s capacity to absorb food later), then eat two massive meals at roughly 11:00 am and 7:00 pm.

Chankonabe is engineered for this:

• Volume. A single bowl can be a litre or more. Multiple bowls per sitting is routine.
• Balance. Protein (meat or fish), carbohydrates (rice, noodles), and vegetables are all in one pot — no assembly required.
• Liquid base. The broth (dashi) rehydrates after training and goes down easily even when the wrestler is tired.
• Communal. The whole stable eats from a shared pot — order is by seniority (highest-ranked rikishi first), and the ritual reinforces stable hierarchy.

A normal person eating a stable-scale chankonabe portion would gain weight immediately. For a training rikishi, it’s just maintenance.

The chicken tradition

One rule applies on tournament days and match mornings: no four-legged meat.

The reason is superstition rooted in the language of winning. In sumo, a loss is signalled the moment a rikishi’s body — other than his feet — touches the clay. If any part of his hand, elbow, knee, or back hits the ground, he has lost. Four-legged animals (cattle, pork) stand with four feet on the ground — which, in the logic of ring superstition, is the stance of a losing wrestler.

The superstition follows the rules of the ring: a rikishi loses the moment his hands touch the floor — the body posture of a four-legged animal. Chicken, by contrast, stands on two legs — upright, feet planted, the stance of a winning wrestler. So on tournament days, chankonabe is almost always torinabe (chicken hot-pot). Pork and beef are reserved for off-days and training periods.

The tradition isn’t universally enforced today — modern stables add beef, pork, and even cheese, tomato, or curry broths to their chankonabe repertoire — but most still follow the chicken rule during honbasho. It’s also the reason chicken-based chankonabe is considered the “classical” variant.

What’s in a typical chankonabe

Recipes vary by stable — each oyakata has their own version — but the base ingredients are consistent:

The final portion of a meal is shime — the broth is thick with accumulated flavour from everything cooked in it, and the stable typically adds rice or noodles to soak it up. Nothing is wasted.

What you’ll be served at Kyoto Sumoan

The chankonabe at the Kyoto Sumoan show is prepared in traditional sumo style:

• Chicken-based (torinabe style, following the tournament tradition)
• Fish (typically a mild white fish)
• Tofu (soft silken)
• Seasonal vegetables (varies by season — expect Chinese cabbage, daikon, leeks, mushrooms in winter; lighter summer greens in warmer months)
• Rice served alongside
• Side dishes — small pickled or seasoned accompaniments
• First drink on the house (beer, soft drink, or Japanese tea)

Full meals are served at the 12:00 and 18:00 shows only. The 15:00 show is a lighter “Kyoto-style afternoon tea” variant — smaller portions, the same quality, a softer social pace. The 21:30 late-night show is show-only and does not include dinner.

Vegetarian option is available — ask staff at the venue when you arrive.

Where else to eat real chankonabe

If you can’t get to a sumo show, the authentic stew is still accessible:

• Ryogoku (Tokyo). The Ryogoku district is the home of sumo, and several dedicated chankonabe restaurants cluster near the Ryogoku Kokugikan. Some are run by former rikishi; the recipes reflect specific stable traditions. These are the best in Japan.
• Chankonabe at sumo-stable morning practice (asa-keiko). If you visit an active stable by prior arrangement (the few that accept visitors), you can sometimes share the communal post-training meal. This is rare and unpredictable — but unforgettable.
• General nabe restaurants in Kyoto and Osaka. Many serve chankonabe as one dish on a broader hot-pot menu. Quality varies; not the same as the real thing, but pleasant.

For the curious traveller, the Kyoto sumo show is the easiest authentic entry point — you see the wrestlers who eat it, watch what they do with their bodies, and then share the same meal. That context makes the stew taste like more than just stew.

A note on quantity

Don’t try to match a rikishi’s portion. A wrestler-scale serving would test most visitors’ comfort. The show’s portions are calibrated for a tourist audience — generous, complete, not absurd. You’ll feel satisfied, not defeated.
