THE UNWRITTEN RULES

Living in Korea, day to day

Beyond the notices on your door, there's a whole layer of everyday etiquette nobody hands you in writing — which side of the escalator to stand, why people leave a bag to hold a seat, how the trash really works. Here it is, plainly, so Korea feels less like a test.

Getting around

Stand still on escalators — hold the handrail 에스컬레이터 두 줄 서기

For years Koreans followed a 'stand right, walk left' habit, but the government now officially discourages walking or running on escalators and promotes standing still on both sides while holding the handrail. The Ministry of the Interior and Safety has revived a nationwide two-line standing campaign, citing falls (nearly 78% of serious escalator accidents) and lopsided mechanical wear. Enforcement is soft, so in practice many commuters still leave the left side open for walkers, especially at rush hour.

Why it mattersNewcomers often assume the 'keep left clear' rule is mandatory, but the current official guidance is the opposite — stand still and hold on. The gap between the old ingrained habit and the new safety message can be confusing.

Do thisGrab the handrail and stand still rather than walking up the escalator; don't pressure anyone standing in the 'walking' lane to move.

Let riders exit before you board 내린 후 타기

On the subway, people get on and off through the same doors, so the norm is to wait for everyone to exit before stepping in. Riders stand to the sides of the doorway, take a step back when the doors open, and then board one by one. Pushing in before others are out is considered rude and slows everyone down.

Why it mattersForeigners used to less structured systems may crowd the doors, which locals notice immediately. The orderly flow is what keeps famously busy stations moving.

Do thisStand to the side of the door, wait for the car to empty, then step in.

Source
Queue on the platform markings 줄 서기

Platforms have painted lines and arrows showing where doors will open and where to line up. Riders form two side queues at each door, leaving the center clear for people getting off. Cutting the line or bunching in the middle is frowned upon.

Why it mattersVisitors often don't realize the floor markings indicate an actual queue system, not just decoration. Respecting the lines is a visible sign of good manners.

Do thisFind the door markings on the platform and line up behind others to the side, keeping the center open.

Source
Give up your seat for elders 노약자석

Around 30% of subway seats are 'priority seats' at the ends of each car for the elderly, disabled, injured, and passengers with small children. There's no legal penalty, but by strong social consensus people avoid these seats even when the car is packed and they sit empty. Yielding a regular seat to an elderly person who is standing is also widely expected.

Why it mattersA younger person sitting in a priority seat, or not offering a seat to a visibly older passenger, draws disapproving looks. Age-based deference runs deep in Korean public life.

Do thisLeave the end 'priority' seats empty unless you clearly qualify, and offer your regular seat to an elderly or frail passenger who is standing.

Leave the pink pregnant-woman seats empty 임산부 배려석

Bright pink seats marked with a pregnant-woman symbol are set aside specifically for expectant mothers, including those in early pregnancy who don't yet look pregnant. Introduced system-wide from 2013, the custom is to keep them free at all times rather than only vacating them when a pregnant woman appears. Not every pregnant rider carries the pink 'baby-on-board' badge, so the seat is meant to stay open regardless.

Why it mattersTourists frequently sit in the empty pink seats not realizing they are reserved even when the train is crowded, which locals find inconsiderate. The point is that a pregnant woman should never have to ask.

Do thisDon't sit in a pink seat unless you are pregnant, even if it's the only free spot.

Source
Keep quiet — silent phone, low voice 조용히

Korean subway cars stay remarkably quiet even when packed. Phones are kept on silent, voice calls are avoided or kept very short and hushed, and any music or video is played only through headphones at low volume. Loud conversation or speakerphone use stands out sharply.

Why it mattersThe near-silence surprises many first-timers, and a normal-volume phone call that would pass unnoticed elsewhere feels jarringly loud here. Quiet is treated as basic courtesy to shared space.

Do thisSet your phone to silent, use headphones, and if you must take a call keep it brief and whispered — or step off at the next station.

Source
Wear your backpack on your front in crowds 가방 앞으로 메기

In a full car, a backpack worn on the back becomes an obstacle that bumps and blocks other passengers. The considerate move is to take it off and hold it in front of you, carry it low, or set it between your feet when standing safely. Large bags shouldn't be left on your back during rush hour.

Why it mattersMany newcomers don't notice how much space a backpack takes until they see everyone around them shifting theirs to the front. It's one of the clearest markers of a savvy local rider.

Do thisWhen the train gets crowded, swing your backpack around to your chest or hold it low in front of you.

Source
Board at the front, tap T-money in and out 티머니 태그

On city buses you board through the front door and tap your T-money card on the reader by the driver, then exit through the rear door and tap the card again on the way out. Tapping out is essential: it calculates your distance fare and unlocks free or discounted transfers (up to four a day, within 30 minutes) between buses and subway. On the subway you likewise tap in at the entry gate and tap out at the exit gate.

Why it mattersForeigners often forget the exit tap, which forfeits the transfer discount and can charge a maximum fare. Getting the tap-in/tap-out rhythm right saves real money across a day of connections.

Do thisTap your T-money card when you board at the front and tap again when you get off at the rear door — every single time.

Trust & safety

Hold a seat by leaving your belongings 짐으로 자리맡기

In Korean cafes and study cafes it is completely normal to reserve a table by leaving a bag, phone, or even a laptop on it while you queue to order or step to the restroom. Locals do this routinely and expect the belongings to be untouched when they return. It works because theft risk is low, cafes are blanketed with CCTV, and there is a strong social norm against touching other people's property.

Why it mattersForeigners are often astonished to see an unattended MacBook holding a seat for ten minutes; in most countries it would be gone. It signals just how high the everyday baseline of public trust is in Korea.

Do thisYou can leave a light item to claim a seat briefly, but keep passports, cash, and cards on your body since it is not risk-free.

Source
Phones and wallets left on tables

Beyond cafes, people commonly set phones and wallets on restaurant tables and walk away to the bathroom, expecting to find them exactly where they left them. This reflects a broadly high-trust society where, when something is lost, it is often turned in to a lost-and-found, handed to police, or simply left in place for the owner to reclaim. Korea is described as one of the countries where you are most likely to get your belongings back.

Why it mattersThe casualness surprises visitors from cities where a phone on a table disappears in seconds. It reveals trust as a social default rather than something backed only by locks and security.

Do thisFeel free to relax, but treat this as a low-risk norm, not a guarantee, and stay sensible with high-value items in crowded tourist and nightlife areas.

Source
Lost-and-found return culture 분실물 센터

Korea runs a fast, centralized lost-and-found system: staffed subway stations, CCTV, clear reporting routines, and the national LOST112 database linked to the police. Losing a wallet, phone, or bag on the subway very often ends in recovery because finders routinely turn items in rather than keep them. Unclaimed items are held at station lost-and-found centers before transfer to police after a set period.

Why it mattersMany foreign residents recount leaving a phone on a train and getting it back a day later, which feels almost unbelievable elsewhere. It shows social trust reinforced by public procedure and infrastructure.

Do thisIf you lose something, act fast: note the line, direction, time, and station, then check lost112.go.kr or call the 1330 tourist hotline for English help.

Source
Low street crime and late-night safety

Korea is consistently rated among the safest countries after dark, with homicide under 1 per 100,000 and effectively no gun crime. It is common to see people walking alone to a shop late at night, partly because streets stay busy and lit. Safety is high but not absolute, and vigilance is still sensible.

Why it mattersVisitors from higher-crime cities are struck by how relaxed nighttime feels. The honest caveat is that low violent crime does not mean zero risk, so guard is still warranted.

Do thisWalk and explore at night with normal awareness, but watch out for petty theft in crowded markets and nightlife zones and never leave a drink unattended.

Source
24-hour convenience stores as safe havens 편의점

Round-the-clock convenience stores are everywhere, well lit, staffed, and covered by CCTV, and they function as informal safe zones on the street at any hour. Combined with a dense camera network, their constant presence keeps streets populated and reduces isolation late at night. They are a reliable place to duck into if you feel followed or unsafe.

Why it mattersForeigners quickly learn to treat the nearest GS25 or CU as a refuge, which is unusual in cities where late-night options are scarce. It reframes the convenience store as part of the safety fabric, not just a shop.

Do thisIf someone makes you uncomfortable at night, step into a 24-hour convenience store and wait it out, and always keep an eye on your drink in bars.

Source
Cafe seat-time and study-cafe norms 카공족

Studying or working for hours in a cafe over a single drink is a normalized culture, and the people who do it are affectionately called kagongjok. Small apartments, good Wi-Fi, charging ports, and pleasant ambiance make cafes de facto workspaces, and many venues even provide long tables and solo seating for it. The unwritten deal is one order per person, with an extra drink every couple of hours during busy periods as a courtesy.

Why it mattersNewcomers are surprised that nursing one americano for three hours is welcomed rather than frowned upon. The nuance that catches people out is that small independent cafes and peak hours call for more restraint.

Do thisOrder at least one item per person, and in small or crowded cafes buy another drink every 2-3 hours or free up the table.

Source
Personal space and unapologized bumping

In crowds, streets, and packed subways, people often brush past or bump without saying sorry, and this is not considered rude. It stems from a collectivist culture where minor, unintentional contact is simply overlooked rather than treated as an offense. Attitudes are shifting, though, as many Koreans in their 20s and 30s now expect an apology.

Why it mattersWesterners used to a reflexive 'sorry' can read the silence as hostility when none is meant. Recognizing it as a different norm, not disrespect, prevents needless friction.

Do thisDon't take an unapologized bump personally, and just keep moving as locals do rather than expecting an 'excuse me'.

Source
Staring and privacy norms

Being visibly foreign, especially outside Seoul, often draws open stares, most commonly from older people and young children who see fewer international visitors. This curiosity is generally harmless and not linked to any threat. Public proximity norms also run closer than in the West, so casual physical closeness is normal rather than intrusive.

Why it mattersDirect, prolonged stares can feel unsettling to visitors used to strict eye-contact etiquette, but they rarely signal hostility. Understanding it as curiosity helps you shrug it off.

Do thisTake stares in stride with a calm nod or smile, and don't interpret close public proximity as aggression.

Take your shoes off before entering 신발 벗기

In Korean homes you remove outdoor shoes at the entryway (현관), a sunken area by the door, and step up onto the raised floor in socks or provided indoor slippers. The same applies at many clinics, oriental-medicine offices, traditional floor-seating restaurants, guesthouses, temples and some study rooms. Shoes are lined up neatly, usually toes pointing toward the door.

Why it mattersWearing shoes indoors is seen as dirty and disrespectful, and since people sit, eat and often sleep directly on the heated floor, keeping it clean matters a lot to hosts.

Do thisThe moment you step inside, take your shoes off in the entry area and leave them tidy before stepping up onto the floor.

Source
Floor noise between apartment units 층간소음

Noise passing between apartment units (footsteps, dropped objects, dragging furniture) is a major source of neighbor disputes in Korea's high-density apartments. The government tightened the impact-noise standard to 39 dB in the daytime (06:00-22:00) and 34 dB at night (22:00-06:00). A national mediation body, the Floor Noise Neighbor Center (층간소음 이웃사이센터), handles complaints.

Why it mattersComplaints escalate fast and have led to serious conflicts; as the upstairs neighbor you are usually the one asked to change behavior, and repeated issues can bring mediation or civil claims.

Do thisWear house slippers, lay noise mats in play areas, and avoid running, jumping or loud chores late at night (after 22:00).

Source
Recycling separation by material 분리수거

Recyclables must be sorted by material: paper, cardboard, glass, cans/scrap metal, and plastics (with clear PET bottles often separated from colored plastic). The core rule is empty it, rinse it, remove labels/caps, and keep materials un-mixed. Apartments typically have a fixed weekly collection day and labeled bins in a shared area.

Why it mattersImproperly sorted or contaminated recycling can be rejected or draw building/management-office warnings, and rules vary by district and building so what is accepted differs place to place.

Do thisRinse containers, flatten boxes, and put each material in its correct bin on your building's designated collection day.

Source
Food waste is collected separately 음식물 쓰레기

Food waste is a distinct category, never mixed with general trash. Depending on the district you either use special food-waste bags, a dedicated container, or tag a smart RFID bin that weighs your waste and charges by weight. Bones, shells, tea bags, large seeds and similar hard items usually count as general waste, not food waste.

Why it mattersYou pay for food waste by volume or weight, and mis-sorting (e.g. putting food waste in general trash or vice versa) can lead to rejected collection or fines; methods differ by district.

Do thisDrain off the liquid first to cut the weight/cost, then dispose of it in your district's food-waste bag or RFID bin.

Source
Buy the official volume-rate garbage bags 종량제 봉투

General household trash must go out in the official standard-volume-rate bag (종량제 봉투) printed for your specific district; the bag purchase is how you pay the disposal fee. They come in sizes like 3L, 5L, 10L and 20L and are sold at convenience stores, supermarkets and neighborhood shops. Bags are district-specific and generally not valid outside the gu/si that issued them.

Why it mattersTrash left out in a random bag or the wrong district's bag will not be collected and can incur a fine, so newcomers must buy the correct local bag.

Do thisAsk a nearby convenience store for your district's 종량제 봉투 (name your gu) and use only that bag for general trash.

Source
Large-item disposal requires a paid sticker 대형폐기물

Furniture, mattresses, appliances and other bulky items cannot go out with normal trash; you must report each item to your district (online or at the community/구청 office) and pay a per-item fee based on type and size. You then receive a disposal sticker or printed confirmation number to attach to the item and leave it at the designated spot on the scheduled day. Fees and item price tables vary by district.

Why it mattersDumping a large item without a sticker is illegal dumping and can bring a substantial fine, and unreported bulky waste is simply left behind.

Do thisReport the item on your district's bulk-waste site, pay the fee, and stick the printed confirmation on the item before putting it out.

Source
Ondol heating and floor-based living 온돌

Korean homes are heated by ondol, radiant under-floor heating (now hot-water pipes under the floor) found in the vast majority of housing. Because the floor itself is the warm surface, Korean living is floor-centered: people sit on floor cushions, eat at low tables, and many still sleep on a thin mattress laid directly on the heated floor. Controls are usually a wall thermostat rather than forced-air vents.

Why it mattersHeating your floor rather than the air feels unfamiliar to newcomers, and running ondol hard drives up the 관리비/gas bill, so understanding it helps comfort and budgeting.

Do thisSet the floor thermostat to a moderate temperature and try sitting or sleeping closer to the warm floor rather than expecting warm air from vents.

Source
Air-drying laundry, no dryers 빨래 건조

Most Korean apartments come with a washing machine but no clothes dryer, and the washer usually sits on the enclosed balcony/veranda (베란다). People air-dry clothes on a folding drying rack (빨래건조대) set up indoors or on the balcony. Dryers exist but are less common, largely due to electricity cost and space.

Why it mattersNewcomers expecting a dryer need to plan for slower air-drying and buy a rack, and drying takes longer in humid summer and monsoon season.

Do thisGet a folding 빨래건조대 and dry clothes on the balcony or by a window; open the balcony for airflow during humid months.

Source
Management fees and community notices 관리비

Apartment residents pay a monthly management fee (관리비) covering shared cleaning, security, elevator upkeep, common-area utilities and the management office; itemized statements are posted online (the K-apt system) and in the building. Buildings run under self-governance rules (관리규약) and the management office posts notices in elevators and lobbies about collection days, inspections, water shutoffs, and disinfection. Residents are expected to read and follow these.

Why it mattersUnpaid or misunderstood 관리비 and ignored notices cause friction with the office and neighbors, and the notices carry practical schedules (like waste days and water cut-offs) you need to plan around.

Do thisCheck the elevator/lobby notice board and your monthly 관리비 statement, and pay the fee on time each month.

Table manners

No tipping 봉사료

Tipping is not part of Korean dining culture. Since a 2013 revision to the Food Sanitation Act, restaurants must charge exactly the price on the menu with no surprise fees added afterward, and any service charge (봉사료) at high-end venues or hotels is already built into the bill. Servers earn a guaranteed national minimum wage from their employer, not from gratuities.

Why it mattersForeigners often feel rude not tipping, but leaving cash can actually confuse or mildly embarrass staff, and many Koreans actively resist recent attempts to introduce tip boxes or kiosk add-ons.

Do thisPay the listed price and leave nothing extra; if you loved the meal, just say thank you.

Source
Pour for others, receive with two hands 두 손으로 받기

You generally don't pour your own drink; someone else fills your glass and you fill theirs. When an elder or senior pours for you, receive the cup with two hands (one hand holding it, the other supporting underneath) and give a slight bow of the head. When you pour for them, hold the bottle with both hands the same way.

Why it mattersThe two-hands gesture signals respect and is expected in almost any drinking situation with older people or superiors, so using one hand can read as careless or arrogant.

Do thisKeep an eye on others' glasses and refill them with both hands, and never top up your own.

Source
Turn away when drinking with elders 고개 돌리기

When drinking alcohol in front of someone clearly older or higher in rank, you turn your head slightly to the side, away from them, and often cover the cup and mouth with your free hand. Drinking face-on toward a senior is seen as a small assertion of equality, so the turn is a gesture of modesty and deference.

Why it mattersIt surprises visitors because the elaborate turn-and-cover looks theatrical, but at a first company or family drink it is genuinely noticed and appreciated.

Do thisRotate a quarter-turn away from the senior person and sip discreetly, then turn back.

Source
Wait for the eldest to start 어른 먼저

At the table you wait for the oldest person to lift their spoon or take the first bite before anyone else begins eating. This holds at family meals, work lunches, and any gathering with an age gap, even after everyone has said the customary pre-meal greeting.

Why it mattersDigging in first is one of the most common unintentional slights a foreigner can make, since the whole table quietly holds off until the senior begins.

Do thisKeep your chopsticks down until the eldest person at the table starts eating.

Source
Free side dishes and refills 반찬

Almost every Korean meal comes with an array of complimentary side dishes (반찬) such as kimchi, pickled vegetables, and greens, included in the price of your main dish. Most restaurants give free refills, and some have a self-serve station where you help yourself; you can also ask a server for more.

Why it mattersNewcomers sometimes worry these unordered dishes will cost extra or leave them untouched, but they're free and meant to be eaten and shared.

Do thisTo get more, flag a server and say 'jogeum deo juseyo' (조금 더 주세요), but only take what you'll actually finish.

Source
Call the server yourself 여기요

Korean servers usually leave you alone to eat rather than checking in, so you summon them when you're ready. You call out 'yeogiyo' (여기요) or 'jeogiyo' (저기요) across the room, or press the call button mounted on many tables. This applies to ordering, extra side dishes, or the bill.

Why it mattersForeigners raised to consider calling out or waving as rude often sit waiting indefinitely, but here staying silent just means you never get served.

Do thisWhen you need anything, press the table button or clearly call 'yeogiyo!' to bring a server over.

Source
Sharing the communal stew and dishes 찌개

Stews like jjigae (찌개) and many main dishes are placed in the center of the table and eaten communally by the whole group rather than plated individually. Everyone eats together from the shared pot, typically using a spoon to take stew, often with small individual bowls provided for portioning.

Why it mattersThis close communal eating can startle visitors used to separate plates, and how you dip matters: scooping tidily from the shared pot is normal, but be considerate about the shared spoon.

Do thisTake modest spoonfuls from the shared pot into your own bowl or rice rather than eating continuously straight from the center.

Source
Shoes off at floor-seating restaurants 좌식

Many traditional restaurants seat diners on cushions at low tables on a raised, often underfloor-heated (ondol) platform. Before you step up onto that platform you take your shoes off, because the floor is treated as clean living space you sit and sometimes lean on.

Why it mattersStepping up in your shoes is a real faux pas, and travelers are often caught off guard by having to sit cross-legged on the floor for the whole meal.

Do thisLook for the raised platform and shoe area, remove your shoes before stepping up, and leave them neatly at the edge.

Source
Who pays and splitting the bill 더치페이

Traditionally one person treats the whole table rather than everyone splitting evenly, and when there's an age gap the elder or the host usually pays as a sign of care and standing. This is strong at company dinners (회식), where the senior or the company often covers the bill. Among younger friends, splitting the cost, called 'dutch pay' (더치페이), is increasingly common.

Why it mattersReaching to split the check with a much older host can unintentionally reject their gesture, while newcomers are also surprised that one person quietly paying for everyone is normal.

Do thisIf someone senior insists on treating, accept graciously and offer to cover the next round or a coffee afterward.

Age & hierarchy shape how you speak 존댓말/반말

Korean has distinct speech registers: polite/formal 존댓말 (jondaetmal) and casual 반말 (banmal). Which one you use is decided mainly by relative age and social rank, rooted in Confucian hierarchy, so the same sentence changes form depending on who you're talking to. Using banmal with an elder or stranger can cause real offense.

Why it mattersThis is why Koreans often ask your age within minutes of meeting you: they aren't being nosy, they need to know which speech level and honorifics to use with you. Foreigners are surprised that a friendly 'How old are you?' is actually about showing correct respect.

Do thisAs a foreigner, default to polite 존댓말 with everyone until a Korean explicitly invites you to speak casually.

Source
Give and receive with two hands 두 손으로

When handing over or accepting money, a card, a gift, or a drink, Koreans use both hands, or support the right forearm with the left hand, especially with elders or superiors. The left hand alone reads as careless or disrespectful. A slight bow or nod usually accompanies the exchange.

Why it mattersForeigners routinely reach out one-handed on reflex, which can come across as rude in Korea even during a casual convenience-store payment. The two-handed gesture is one of the most visible everyday courtesies.

Do thisWhen paying, receiving change, or accepting anything from an older person, offer and take it with both hands.

Source
Bowing and nodding as a greeting 인사

A bow or nod is the standard Korean greeting, from a quick head nod among peers to a deeper 30-degree bow for a superior or first business meeting. Handshakes happen in professional settings but are usually paired with a slight bow, often with the left hand touching the right forearm. The depth of the bow signals the degree of respect.

Why it mattersKoreans don't expect foreigners to bow perfectly, but a small nod is warmly appreciated and instantly reads as culturally aware. Newcomers often over-rely on Western-style firm handshakes and eye contact, which can feel too forward.

Do thisReturn greetings with a small nod of the head; add a deeper bow when meeting someone clearly older or senior.

Source
Exchanging business cards politely 명함

Business cards are exchanged at the start of a meeting, standing, presented and received with both hands. You should read the card for a few seconds, acknowledge the person's name and title, and in formal settings lay it face-up on the table rather than pocketing it immediately. Writing on someone's card in front of them or stuffing it in a back pocket is considered disrespectful.

Why it mattersIn Korea a card conveys the person's name, position, and status, so how you treat it signals how you regard them. Foreigners who glance and pocket a card the Western way can unintentionally offend.

Do thisReceive a card with both hands, study it for a moment, then place it on the table in front of you during the meeting.

Source
Address people by title, not first name 호칭 (씨/님/선배)

Koreans usually address one another by role or title plus an honorific rather than by bare first name: 씨 (ssi) for peers, 님 (nim) and job titles like 사장님 (boss) for seniors, and 선배 (sunbae) for someone more senior in school or work. Calling an adult by their given name alone is considered rude.

Why it mattersForeigners accustomed to first-name informality are surprised that even close colleagues rarely use bare names. Getting someone's title right is a core sign of respect for the social relationship.

Do thisAddress a senior colleague as their title plus 님 (e.g. 팀장님), not by their first name.

Source
Housewarming gifts: toilet paper and detergent 집들이

When invited to a Korean housewarming (집들이), the classic gifts are toilet paper and laundry detergent. Toilet paper unrolls in one long unbroken strand, symbolizing that everything in the new home will go smoothly and good fortune won't run out; detergent's bubbles symbolize money and prosperity bubbling up. These evolved from older gifts of candles and matches to 'light up' the home.

Why it mattersForeigners find it bizarre to gift bathroom supplies, but in Korea these are thoughtful, auspicious presents, not a joke. They are practical and carry genuine good-luck symbolism.

Do thisBring a nice pack of toilet paper or laundry detergent (or both) to a housewarming and mention the good-fortune wish behind it.

Source
Fine dust, masks, and the air-quality app 미세먼지/황사

Air quality is part of daily planning in Korea, worst in spring when yellow dust (황사) blows in and during high fine-dust (미세먼지) days. Many people check an app such as AirKorea or AirVisual before going out and wear a certified KF94 (or KF80) mask on bad days; ordinary cloth or surgical masks don't filter fine particles. On red-level days people shift plans indoors.

Why it mattersNewcomers often ignore the haze or reach for a flimsy cloth mask, not realizing locals track color-coded forecasts and keep KF94 masks on hand. The color grade (green/yellow/orange/red) drives real decisions about outdoor activity.

Do thisInstall an air-quality app and keep a few KF94 masks handy; wear one and move plans indoors when the index hits orange or red.

Source
Bathhouse (jjimjilbang) etiquette 찜질방

At a Korean bathhouse/sauna you must shower and scrub thoroughly with soap before entering any communal pool; getting in unwashed is a serious breach. The wet bathing area is gender-separated and fully nude, which is completely normal and non-sexual to Koreans, while the co-ed common lounge requires the provided matching t-shirt and shorts. Keep voices low, tie up long hair, and don't take photos.

Why it mattersThe mandatory pre-bath scrub and casual communal nudity surprise many foreigners. Unlike Japanese onsen, tattoos are generally fine in Korean jjimjilbang.

Do thisShower and wash completely at the seated stations before you step into any shared bath or pool.

Source
Seasonal foods: samgyetang, kimjang, patjuk 삼복/김장/팥죽

Korean eating follows the seasons. During the three hottest 'dog days' of summer (삼복: 초복·중복·말복) people eat piping-hot ginseng chicken soup 삼계탕 to 'fight heat with heat' and restore stamina. In late autumn families gather for 김장 to make big batches of winter kimchi, and on the winter solstice (동지) they eat red-bean porridge 팥죽, traditionally believed to ward off bad luck.

Why it mattersForeigners are puzzled that Koreans eat boiling soup on the hottest day of the year, but this stamina logic is deeply held. These foods mark the calendar and are often shared communally.

Do thisTry a bowl of 삼계탕 on a sambok day in July or August, when restaurants fill up with people doing exactly that.

Source
Ppalli-ppalli (fast-paced) culture 빨리빨리

빨리빨리 ('hurry, hurry') is a pervasive drive to do things fast and efficiently, a legacy of Korea's rapid post-war development. It shows up as near-instant restaurant service and call buttons at the table, same-day delivery, people jabbing the elevator 'close' button, and an expectation of quick replies on KakaoTalk. Speed is often equated with competence.

Why it mattersNewcomers are startled by the pace and can read the bustle or a jostle as rudeness, when it's just the ambient tempo. The upside is remarkable convenience and speed of service.

Do thisReply promptly to messages and be ready to move quickly, but set your own boundaries so the pace doesn't burn you out.

Customs, not rules — regional and generational variation is normal, and etiquette keeps changing. This is general orientation, not legal, medical, or immigration advice.
