Living abroad can be an exciting adventure, but it also comes with its own set of surprises, especially when moving to a country like South Korea. If you're planning on relocating to Seoul, it's important to prepare not just mentally and emotionally, but also practically. Here are eight essential things to know before making the big move.
1. Korea’s trash system is very specific
Forget the “one bin fits all” method. In Korea, trash disposal is categorized and enforced with strict rules. You’ll need to separate food waste, plastics, glass, paper, and general trash, and even within those, some items like bottle caps and styrofoam have their own rules. You also can’t use just any garbage bag - specific bags must be purchased, depending on your area. Many foreigners say adjusting to this system is one of the hardest parts of living in Korea.
2. You need a registration number for everything
If you plan to stay long term, make getting your Alien Registration Card (ARC) your top priority. Without this, you won’t be able to open a bank account, get a local phone plan, or even book tickets to certain events online. Most Korean websites and apps require this number to register or use their services.
3. Korean tap water may cause hair loss
While safe to drink, Korean tap water often dries out your scalp due to its mineral content. It’s common for locals and expats alike to install filtered shower heads, which can help prevent excessive hair shedding. Even idols like Jennie are known to carry their own filtered shower heads while traveling.
4. Prepare to climb a lot of stairs
Korea’s public transportation is world-class, but be warned - there will be stairs. A lot of them. Subway stations in Seoul are notorious for their long staircases and multiple exits. Elevators and escalators exist, but they’re not always conveniently located, so get ready for some unexpected cardio.
5. Korea runs on seasons—literally
Korea is a country that leans heavily into its four distinct seasons. What you wear, eat, and even shop for will often depend on the time of year. For example, roasted sweet potatoes are a winter staple, while you may not find them easily during summer. If you’re craving a specific food or product, know that it may only be available seasonally.
6. Always carry some cash
Despite Korea being largely cashless, local markets, food stalls, and certain mom-and-pop shops still only accept cash. It's a good idea to always have some on hand, especially if you're venturing into smaller neighborhoods or older districts.
7. Trends spread like wildfire
Korean trends escalate fast. From snacks to fashion and beauty, what’s hot will suddenly be everywhere. Remember when tanghulu or salt bread became massive hits? One day it's just a niche, the next it’s on every corner. Trend culture is fast-paced and can feel overwhelming, but it's also part of the fun.
8. Popular items will sell out instantly
Once something goes viral, it’s gone. Whether it’s BTS Jungkook's favorite kombucha or a lipstick used by Kim Ji Won on 'Queen of Tears,' expect it to be sold out for weeks. Korean consumer culture is trend-driven, and hype items fly off the shelves faster than you can click “add to cart.”
Moving to Korea can be exciting, but it’s full of cultural quirks and logistical surprises that may catch newcomers off guard. With a little preparation and flexibility, though, it can be one of the most enriching and memorable chapters of your life. Safe travels—and welcome to Seoul!
