In South Korea it is polite to greet others with a handshake or a small nod; when meeting someone older or in a formal setting, a slight bow is appreciated. Use titles (such as Mr or Ms) or the person's surname rather than jumping straight to first names unless invited to do so.
Shoes must be removed before entering a Korean home, and bringing a small gift for the host is considered polite. When giving or receiving something, use your right hand — ideally supported by the left — and remember that seniority plays an important role in social interactions; for example, you should not begin eating until the eldest person at the table has started. Koreans may ask your age or marital status early in conversation as this helps them determine appropriate forms of address. Physical contact with strangers is uncommon, and people may appear reserved until they get to know you.
Certain gestures carry cultural meaning. Never leave chopsticks standing upright in a bowl of rice, as this resembles funeral practices, and avoid beckoning someone with the palm facing up and a single finger. Writing a person's name in red ink is traditionally associated with death, and the number four is considered unlucky. Hanbok, the traditional costume, is worn mainly on holidays and special occasions: men wear loose trousers called baji and a short jacket, while women wear a wrap-around skirt (chima) with a short jacket (jeogori).
Tipping is not customary. In most restaurants, cafés and taxis you are not expected to tip; some businesses that follow international models may accept it, but insistence or expecting a tip can cause discomfort.
For photography, always ask permission before photographing people, especially in more rural or traditional settings. In temples or religious sites, stay respectful: avoid using flash or photographing rituals without asking. Be mindful of signs that restrict photography and follow staff instructions.
