Why eat scalding chicken soup when it is over 30 degrees and swampy outside? Because it is boknal (복날), one of Korea’s three hottest “dog days,” and the operating belief is iyeolchiyeol (이열치열, literally “treat heat with heat”). The first of the three, Chobok, falls on Wednesday, July 15, 2026.
I know how that sounds. A coworker on our overseas team watched me lower my face into a bowl of boiling broth in the middle of July, waited for me to come up for air, and asked why. Not as a joke. He genuinely wanted to know what the soup was supposed to be doing.
And I answered him immediately, with total confidence. I said it was ancient. A thousand years of it, kings and farmers and my great-grandmother, the kind of tradition you do not question because it is older than anything you could question it with. Then I went and looked it up, the way you do when you hear yourself sound that sure. I was wrong by roughly nine centuries.
So this is the corrected answer, the one he actually deserved, with the parts nobody puts in the travel guides: what boknal is, why the dates move around, why the bowl now costs more than most people’s dinner, and the uncomfortable history that summer 2026 is quietly closing the book on.
What is boknal, and why does the date move every year?
Boknal is not one day. It is three, spread across the peak of summer, and together they are called sambok (삼복, “the three bok”): Chobok (초복, the first), Jungbok (중복, the middle), and Malbok (말복, the last). The stretch they bracket is the hottest, wettest, most miserable part of the Korean year. The closest English equivalent is “the dog days,” and honestly it fits.
Here is the first thing that surprises foreign readers: boknal is not a public holiday. Nobody gets the day off. It is a normal workday with a soup obligation attached, which is a strange sentence to write and a stranger thing to live. In my office the sign that boknal has arrived is a message in the team chat, usually from whoever is most senior, that says something like “boknal lunch, 11:30, don’t be late.” We leave half an hour early on purpose. Any later and the queue outside the samgyetang place near the office runs down the block.
The dates move every year because they are set on the traditional sexagenary calendar, not the solar one. Chobok is the third gyeongil (경일, a “geng” day in the old sixty-day cycle) after haji (하지, the summer solstice). Jungbok is the fourth. Malbok is the first gyeongil after ipchu (입추, the calendrical start of autumn). Usually that spaces them ten days apart, tidily.
2026 is not tidy. This year the cycle lands so that Malbok gets pushed a full extra cycle back, which makes 2026 a wolbok (월복) year: the gap between Jungbok and Malbok stretches to 20 days instead of the usual ten. The summer’s last restorative meal arrives in the middle of August, when it is still, reliably, unbearable.
| 2026 sambok | Date | Gap from previous |
|---|---|---|
| Chobok (초복) | Wednesday, July 15 | — |
| Jungbok (중복) | Saturday, July 25 | 10 days |
| Malbok (말복) | Friday, August 14 | 20 days (wolbok year) |
One practical note for anyone living here: Jungbok falls on a Saturday this year, which means the restaurants will be packed with families instead of office teams. Chobok, on a Wednesday, belongs to the office workers.
Why hot soup on the hottest day of the year?
Ask any Korean parent and you get the physiology lecture before you get the answer. Summer heat, in this view, drains the body outward: you sweat all day, your surface runs hot while your core runs cold and weak. Pour iced water and cold noodles into that and you shock a gut that is already struggling, which is why Korean parents nag about cold food in summer the way other parents nag about wet hair in winter. So you do the opposite. You eat something hot and restorative, you sweat hard on purpose, and the theory is that you come out the other side rebalanced. Old logic, internally consistent, and nowhere close to the logic I would have arrived at on my own.
That is iyeolchiyeol. Fight fire with fire, except the fire is a chicken.
The food itself has a name: bokdarim (복달임), from bok plus the native Korean word dalim, “simmering.” It sits inside the broader category of boyangsik (보양식, restorative or stamina food), the class of dishes Koreans eat not because they are craving them but because the body is understood to need them. There is a whole vocabulary in Korean for eating as maintenance work.
Do I believe it? Not really, if you mean do I think broth outperforms an air conditioner.
But here is the part I did not expect to admit to my coworker. The ritual works on me anyway. There is a specific feeling about twenty minutes after a bowl of samgyetang, walking back to the office with your shirt stuck to your back and the building’s air conditioning hitting you at the door, where you feel weirdly, stupidly fine. Cooled from the inside out. Whether that is physiology or just the placebo of having done the thing my grandparents did, I could not tell you, and after thirty-something summers I have stopped trying to separate the two.
So what is actually in the bowl?
Samgyetang (삼계탕, ginseng chicken soup) is the boknal dish that flattened all the others. A whole young chicken, small enough to sit in a single stone pot, stuffed with glutinous rice and simmered until the meat gives up. Inside and around it: ginseng, jujube, garlic, sometimes chestnut or gingko. The broth comes out milky and almost aggressively plain. You get salt and pepper on the side and you season it yourself, bite by bite, because it is deliberately not seasoned for you.
It is not spicy. It contains no chili at all, which makes it one of the safest possible entry points into Korean food for anyone who finds gochujang (고추장, Korean red chili paste) punishing.
And this is where my confident answer to my coworker fell apart. Samgyetang is not ancient. The boknal dish our great-grandparents ate was yeongye baeksuk (연계백숙), plainly boiled young chicken with no ginseng in it. The ginseng version showed up as a restaurant item in the 1950s, under the name gyesamtang (계삼탕), using ginseng powder because fresh root was tightly controlled. Fresh ginseng (수삼, susam) became usable in the 1960s as trade rules loosened and refrigeration spread, and samgyetang only settled in as the summer restorative dish from around the mid-1970s, once ordinary families could afford to eat meat on a normal Wednesday. So the thousand-year-old tradition I described with such authority is roughly as old as my parents’ marriage. My grandfather would have eaten it as a novelty.
It is also not the only option. The boknal menu is wider than the tourist version suggests:
- Jangeo (장어, freshwater eel) — grilled, the stamina food with the most eyebrow-waggling attached to it.
- Chueotang (추어탕, loach soup) — ground-up freshwater loach in a thick, earthy, perilla-heavy broth. An acquired taste, and a serious one.
- Duck — boiled or braised whole, the pick when a team is too big for individual pots.
And there is the counterprogramming, for people who reject the whole heat-with-heat premise. They exist, they are not shy about it, and they eat kongguksu (콩국수, chilled soybean-broth noodles, thick and nutty and blank until you salt it) or naengmyeon (냉면, cold buckwheat noodles). My spouse is firmly in this camp and considers the queue outside the samgyetang place a form of collective delusion. Our kid takes her side, mainly because ginseng is bitter and children are honest.
Why does a “humble” summer soup now cost more than dinner?
18,154 won. That is what one bowl of samgyetang averaged in Seoul as of May 2026, according to the Korea Consumer Agency’s price portal (한국소비자원 참가격, Chamgagyeok). Five years earlier, in May 2021, the same bowl averaged 14,077 won. That is 4,077 won more, a rise of 29.0%, and it is the part of boknal that Koreans complain about more than any other.
Same chicken, same stone pot, same twenty minutes of sweating. Four thousand won more.
What that does is push samgyetang into second place among Seoul’s common eating-out dishes, behind only samgyeopsal (삼겹살, grilled pork belly), the pork-barbecue standard that Koreans treat as the default cost of feeding a table. A soup that exists in the cultural imagination as peasant food, as the thing you eat because you are depleted, is now the second most expensive normal lunch in the city. It is beaten by grilled pork and nothing else.
| Dish (Seoul average, May 2026) | Price |
|---|---|
| Samgyeopsal (삼겹살, pork belly), 200g | 21,321 won |
| Samgyetang (삼계탕) | 18,154 won |
| Naengmyeon (냉면) | 12,615 won |
| Bibimbap (비빔밥) | 11,769 won |
| Kalguksu (칼국수) | 10,038 won |
The obvious explanation would be chicken, and the obvious explanation is wrong. Chicken itself rose only around 20% over those five years. The rest of the increase is everything else in the pot and around it: ginseng, jujube, glutinous rice, and then the two costs that quietly eat every Korean restaurant alive, rent and labor. Outside the capital it is gentler, but not by enough to plan a trip around: Busan averaged 17,028 won in the same survey.
I remember when a bowl was comfortably under 15,000 won and I did not think about it at all. Now a boknal team lunch is a genuine dent in the month, and the arithmetic is not subtle: five people, one round of soup, and you are past 90,000 won before anyone has ordered a drink.
Which is exactly why the supermarket aisle has become a battlefield. Emart, CJ CheilJedang’s Bibigo line, the convenience-store chains, Ourhome, all of them now sell retort-pouch samgyetang you microwave at home for a fraction of the restaurant price. It is not as good. It is not remotely as good. But when the famous Seoul restaurants are asking around 20,000 won a bowl, “not as good” starts sounding like a reasonable trade, and plenty of families I know have quietly made it.
The question foreigners are too polite to ask
I will just answer it, because I would rather you heard it from someone who lives here than from a comment section.
Yes, boknal was historically the day associated with boshintang (보신탕, dog-meat soup). For a long stretch of the twentieth century it was one of the standard bokdarim dishes, particularly among older men, and it is the single thing about this season that foreigners have heard of and cannot ask about at lunch without the table going quiet.
So, where it actually stands. In January 2024 Korea’s National Assembly passed a special act ending the breeding, slaughter, and distribution of dogs for consumption. It was promulgated the following month, in February 2024, and came into force that August, with a three-year grace period running from the date of promulgation. The criminal penalties switch on at full enforcement on February 7, 2027: up to three years in prison or a 30 million won fine for slaughter, up to two years or 20 million won for raising or selling. Which means this summer, 2026, is the last sambok season before the ban bites.
The industry is not waiting for the deadline. As of December 2025, 1,204 of 1,537 registered dog farms had closed — 78% of them, leaving 333 farms and roughly 37,000 dogs. The government structured the buyout to reward moving early: 600,000 won per dog for farms that shut down quickly, 225,000 won for the ones that drag it out. The incentive worked about as well as incentives ever do.
What does this mean for you, practically, if you are visiting or living here? Essentially nothing. You will not encounter it. The restaurants that remain are few, elderly, unmarked in any way you would notice, and vanishing on a legal clock. My generation did not grow up eating it, and my kid’s generation will grow up not knowing the word. That shift happened inside one lifetime, and I do not think most Koreans have fully registered how fast it went.
Boknal FAQ
Is boknal a public holiday in Korea?
No. All three boknal days are ordinary workdays. Offices, schools, and banks operate normally. The only visible difference is that lunch queues get long and team lunches get scheduled early.
Do I need a reservation for samgyetang on boknal?
In my experience most samgyetang restaurants do not take lunch reservations, so the strategy is timing, not booking. Arrive before 11:45 or after 1:15. The famous places in central Seoul can run 30 to 60 minutes of queue on Chobok itself. On a normal non-boknal day you can walk straight in.
What do I order on boknal if I do not eat chicken?
Grilled jangeo (eel) or a duck dish for a hot restorative meal. Chueotang (loach soup) if you are adventurous. If you want out of the hot-soup logic entirely, order kongguksu or naengmyeon, which is what a good share of Koreans do anyway.
Is samgyetang spicy?
Not at all. There is no chili in it. The broth is deliberately mild and you salt and pepper it yourself at the table, which makes it one of the easiest Korean dishes for anyone who cannot handle heat.
Is dog meat still served in Korea?
It is being phased out under a 2024 law, with full criminal enforcement beginning in February 2027. By December 2025, 78% of registered farms had already closed. As a visitor or resident, you will not encounter it unless you go looking for it deliberately.
Wednesday, 11:30
The monsoon I wrote about the other day is not finished with us. There is rain in the forecast for this week, the pavement has not been dry in days, and the heat has simply moved in on top of it. That is the actual rhythm of a Korean summer, and it is worse than the tidy version: the rain does not politely stop and hand the season over to the sun. They overlap. You walk to lunch through both.
Which is the part that makes boknal look genuinely unhinged from the outside, and I want to be honest about it rather than sell you the postcard. Chobok does not arrive after the rain, as a reward. It arrives in the middle of it. On Wednesday the rain is forecast to be back, the air will be wet enough to drink, and several million people will go stand in a queue for soup served at a rolling boil.
So on Wednesday my team will walk out at 11:30, sweat through a five-minute walk under whatever the sky is doing, sit down in a room where the air conditioner is losing, and eat boiling soup out of a stone pot that stays boiling for the entire meal. We will not talk about why. Someone will spoon the rice out of the chicken and complain about the price. Someone will say the broth is better here than at the place near the old office. Then we will walk back, and for about an hour, we will all feel unaccountably good.
My coworker is coming with us. He asked to. I told him to order it without the salt at first, taste the broth as it is, and only then decide what it needs.
