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.
