Subway, currency, etiquette, and language survival — the things that save the trip, with specifics.
Korea charges for household waste by the bag and sorts it by material. Here is how to handle it in a short-term rental without leaving your host a fine. KO: 한국 숙소 쓰레기 버리는 법: 봉투·음식물·요일
Korea feels cashless until a market grill, a temple gate, or a 2am taxi says otherwise. Where paper won still wins, and how to pull it from a machine that only half-speaks English. KO: 카드가 안 되는 노점과 현금 인출
Every Seoul bus has a card reader by the rear door. If you skip it, you can lose the transfer discount on your next ride. KO: 버스 하차 태그, 환승 할인을 지키는 두 번째 삑
Checkout is at eleven, the flight is at nine. Seoul's stations solve the ten hours in between with a locker and a one-time code, if you know which ones fit a suitcase and when the station closes. KO: 지하철 물품보관함에 짐 맡기기
Seoul's subway stops sooner than you think. The owl bus, the taxi surcharge clock, and the pass that covers both — read the night before it strands you. KO: 막차 이후, 서울에서 집에 가는 법
In Korea the bag is the bill. Household waste leaves in a district-printed volume-rate bag, food waste goes somewhere else entirely, and the street has almost no bins. KO: 구마다 다른 종량제 봉투
Before it asks what you want, a Korean kiosk asks where you will drink it. Maejang or pojang decides whether the coffee arrives in a mug or under a lid. KO: 매장이냐 포장이냐: 키오스크의 첫 화면
One card, one 30-minute window, and a beep most visitors miss. Ride Seoul's subways and buses the way the fare system was built to be ridden. KO: 환승입니다: 내릴 때 찍어야 하는 이유
Seoul's subway is easy to ride and quietly hard to ride well. The difference is a two-digit number most visitors walk past for a week. KO: 승강장 문 옆 숫자, 제대로 타는 법
On a 나쁨 morning the city vanishes into white. How to read Korea's fine-dust numbers, buy the right mask, and swap the mountain for a still-good day indoors. KO: 미세먼지 나쁨인 날을 읽는 법
The pin is right and the restaurant is still missing. How Korean road-name addresses work, and why the last part of one points upward rather than along the street. KO: 주소 읽는 법: 길, 번호, 그리고 층
The counter is empty and a backlit screen is waiting. A ground-level guide to Korea's self-order kiosks — the buttons, the language tab, the card that gets refused. KO: 한국 식당 키오스크, 화면 읽는 법
Korean household rubbish is sorted by law, and the bag that carries it is only valid in the district that sold it. What to ask for, and where each thing goes. KO: 종량제 봉투는 구마다 다르다
Seoul's buses are colour-coded on purpose. Learn what each colour promises, why you tap twice, and the single miss that costs you a transfer. KO: 서울 버스의 색을 읽는 법
Three digits, free, answered around the clock: how Korea's 1330 hotline puts a live interpreter between you and the taxi driver, the pharmacist, the locked door. KO: 1330, 한국어를 대신 말해주는 번호
A restaurant listed 11:00–22:00 can be dark at four and refusing orders at nine. Three pieces of Korean signage explain why, and let you plan around them. KO: 브레이크타임, 라스트오더, 정기휴무
Land at Incheon, open Google Maps, and walking directions go blank. Korea keeps its map data at home — here are the two apps that actually route you, and how to search them without typing Hangul. KO: 구글 지도가 멈추는 나라에서 길을 찾는 법
Seoul gives directions in numbers, not landmarks. Exit numbers, car-and-door coordinates, and the map apps that actually route you. KO: 6번 출구, 4-3 앞에서
A lit red sign on the dashboard means the cab is free. How to flag one down, ride it, and pay — the app, the meter, the after-midnight surcharge, and why you never tip. KO: 빈 차의 빨간 불, 서울에서 택시 타는 법
Leave something on a Seoul train and it does not vanish. It enters a filing system with four addresses, weekday hours, and a clock that runs about a week. KO: 두고 내린 것들이 가는 곳
In Seoul, an address is often a single digit at the top of a staircase. Learning to read exit numbers changes how the city opens. KO: 출구 번호로 길을 찾는 법
Above ground, Seoul locates itself by subway exit. A short field guide to the numbered doors — and how to pick the right one before you tap out. KO: 출구 번호가 곧 주소다
Korean rentals hand you a spotless flat and a one-word note: 분리수거. Here is the part nobody explains — the right bag, the food-waste stream, and the night it all goes out. KO: 숙소에서 아무도 안 알려주는 쓰레기 규칙
On a Seoul platform, the difference between an escalator and a 200-metre march is decided before you board. The maps already know which car you want — here is how to read them. KO: 지하철, 어느 칸에 탈 것인가
An empty coffee cup and no bin in sight is not neglect — it is policy. A ground-level guide to where Seoul's trash actually goes, and how to travel without carrying yours all afternoon. KO: 쓰레기통 없는 거리, 그럼 어디에 버릴까
In more Korean dining rooms the host is a touchscreen. Here is the fixed order it asks in, and the thirty seconds that keep the queue behind you calm. KO: 키오스크 앞에서 당황하지 않는 법
The reader by the back door is the whole game. Tap off, and Seoul's transit system treats your bus, subway and next bus as one fare instead of three. KO: 버스에서 내릴 때 카드를 찍는 이유
A Korean address stops at the door. The rest is vertical — a café on three, a record bar underground — and the sign column outside tells you where to press. KO: 층마다 다른 가게, 한국 건물 읽기
A laminated A4 sheet, no photos, no English, and a server already halfway to the next table. Here is how to read the columns before you have to order. KO: 한국 식당 메뉴 빠르게 읽는 법
