Get ready to feel a little younger (or older!). In South Korea, they have a unique way of calculating age that differs from the international standard.
In the traditional Korean age system, everyone is considered one year old at birth. This is because they consider the time spent in the womb as part of a person's life. But it gets even more interesting: everyone gains another year on New Year's Day, regardless of their actual birthdate. So, a baby born on December 31st would turn two years old on January 1st!
This means that Koreans can be one or two years older than their international age, depending on their birthday.
While this traditional system was widely used in everyday life, South Korea officially adopted the international age-counting system in June 2023. However, the Korean age system is still deeply ingrained in the culture and continues to be used in social interactions.
In South Korea, you might be surprised to be greeted with "밥 먹었어요?" (Bap meogeosseoyo?), meaning "Did you eat rice?" While seemingly unusual, this question reveals a lot about Korean culture. Rice is a staple food and is deeply ingrained in their identity, so asking about someone's rice consumption expresses care and concern for their well-being.
In this collectivist society, this question acts as a social check-in, similar to asking, "Are you taking care of yourself?" It demonstrates genuine interest in the other person's overall well-being. "Did you eat rice?" can also function as a casual greeting, like "How are you?" but encourages a more personal response and deeper interaction.
While many countries observe Buddha's Birthday with solemn rituals such as meditation and chanting, South Korea transforms this occasion into a lively, carnival-like atmosphere. The highlight of the festivities is the Lotus Lantern Festival (Yeondeunghoe), where thousands of colorful lanterns shaped like lotus flowers illuminate the streets and temples.
What sets South Korea apart is its embrace of contemporary culture during this traditional event. In addition to the customary offerings of free meals and tea at temples, many celebrations feature DJs and live music performances. This fusion of traditional Buddhist practices with modern entertainment attracts a diverse crowd, including younger generations who may not typically engage in religious events.
South Korea is home to some truly unusual museums. For example, there's Poopoo Land, a museum entirely dedicated to the subject of poop, where you can even attend a "poo party"! If that's not strange enough, consider the Haewoojae Museum, a house shaped like a toilet. This quirky museum was once the home of a mayor obsessed with toilets, and now it's a free attraction for anyone curious enough to visit.
Created by King Sejong the Great in the 15th century, Hangul was designed to increase literacy among his people. Unlike many alphabets that evolved organically, Hangul was scientifically crafted with simple consonant and vowel symbols representing the shape of the mouth when making those sounds.
These visual phonetics make it incredibly easy to learn. With just 24 basic letters and a few simple rules, anyone can master the basics of Hangul in a short amount of time.
You might be surprised when you know that Hangul Day, celebrated on October 9th, is even a national holiday!

If you're dining out in South Korea, especially if you're used to tipping in the US, remember that tipping isn't expected or even desired. It can actually be seen as rude! Unlike in the US, service staff in South Korea earn a fair wage and don't rely on tips. So, just pay the amount on your bill – no need to add anything extra.
One of the most surprising things for visitors to South Korea might be the relaxed attitude towards public drinking. It's perfectly legal to enjoy alcoholic beverages outdoors, whether you're having a picnic in a park, relaxing by the Han River, or simply walking down the street. This might seem unusual to people from countries with strict open-container laws, but it's a normal part of Korean culture.
Alcohol often acts as a social lubricant in South Korea, facilitating conversation and bonding among friends and colleagues. The abundance of convenience stores selling a wide variety of alcoholic beverages makes it incredibly easy to grab a drink and enjoy it wherever you like. While public drinking is permitted, it's generally expected that people drink responsibly and avoid excessive intoxication or disruptive behavior.

While personality tests are popular worldwide, South Korea takes them to another level. People readily share their MBTI type as a way to understand themselves and others, and it's often a key topic of conversation when meeting new people. You might even find MBTI compatibility charts in cafes or see them mentioned in dating profiles.
While MBTI is popular globally, its prevalence in South Korea is on another level. Koreans frequently use MBTI to understand themselves, navigate relationships, and even make decisions. It's common to see MBTI types listed on social media profiles and dating app bios, and they are even discussed in TV shows.
Think kimchi is just one thing? Think again! South Korea actually has over 150 different kinds of kimchi. It's not just spicy cabbage and radishes - there's a huge variety of flavors and ingredients. In fact, the Kimchi Field Museum has records of 187 different types! Kimchi is so important to Korean culture that it's even on UNESCO's Intangible Cultural Heritage List.
In South Korea, taking care of your appearance is considered very important. Many people regularly visit skin clinics to achieve the popular "glass skin" look, which is clear, smooth, and flawless.
It's easy to find skincare products in South Korea, as Olive Young stores are on almost every busy street. These stores offer a huge selection of beauty and lifestyle products from many different brands. Even international brands like Sephora have struggled to compete with the popularity of Korean cosmetics.
South Korea is also the world leader in plastic surgery. It's so common that many young people even get procedures like double eyelid surgery as a graduation gift.
South Korea has a strong focus on achieving flawless skin, a standard that crosses gender lines. In fact, Korean men lead the world in per capita spending on skincare products. It's common to see men wearing makeup as part of their grooming routine. The influence of male K-pop idols, who frequently star in major beauty product campaigns, further drives the pursuit of “glass skin.”
In Korean, the word for the number four sounds the same as the word for "death." Because of this, the number four is considered unlucky.
To avoid this association, some buildings in South Korea don't have a fourth floor! They might label it "F" instead. And if an address has a lot of fours in it (like apartment 404), the property value can actually be lower.
So, if you're ever in an elevator in South Korea and can't find the button for the fourth floor, try pressing "F" instead!
Many people in South Korea believe in "electric fan death," the idea that sleeping directly under a running fan all night can kill you. This is actually a common myth, and there's no evidence to support it. Even though the media has repeatedly said it's not true, lots of people still believe in this superstition. That explains why many Koreans sleep with windows open or use fan timers, even on hot nights.
In South Korea, the "jjimjilbang" takes relaxation and communal bathing to a whole new level. Imagine a sprawling complex filled with hot tubs, saunas, steam rooms, and relaxation areas, all designed to melt away stress and promote well-being.
But it's not just about soaking and sweating. Jjimjilbangs are social hubs where people gather to chat, unwind, and enjoy various amenities like massage rooms, restaurants, and even entertainment zones.
One of the most distinctive features of a jjimjilbang is the communal nudity in the bathing areas, separated by gender. While it might seem daunting to some, it's considered a natural part of the experience and reflects a cultural comfort with the human body.
Don't forget the fashion statement! Jjimjilbangs provide guests with matching outfits, usually a t-shirt and shorts, to wear in the common areas. And be sure to try the "yangmeori," a sheep's head towel hat that's become a quirky symbol of jjimjilbang culture.
In South Korea, writing someone's name in red ink is a major cultural faux pas. It's considered very disrespectful, like wishing bad luck or even death upon them. This belief stems from an old superstition, but it's still taken quite seriously by many Koreans today. So, if you're ever writing a Korean person's name, stick to blue or black ink to be safe!
You might get hungry while hanging out by the Han River. Do not worry about finding a restaurant. You can order food right to your picnic mat. Delivery drivers in Korea are experts. They find customers in parks or on bridges without a proper address. The service does not stop there. Locals often leave their dirty dishes outside their front door after eating. The delivery staff simply comes back and collects them later.
Romance is a public affair in South Korea. You will see young couples wearing identical outfits on the street. Locals call this the "Couple Look." It shows the world they are together. The calendar also offers more chances for romance. Women give chocolate on Valentine’s Day. Men return the favor on White Day in March. Then comes Pepero Day in November. People exchange chocolate-covered stick snacks to show affection.
Ask a local for their name. There is a good chance they will say Kim. Lee and Park are the next most common answers. These three surnames cover nearly half the population. It reflects the long history of family clans in the country.
Get ready to smile for the camera. You probably grew up saying "cheese" for photos. In Korea, people say "kimchi" instead. The "i" sound at the end forces your mouth into a wide grin. It is a fun quirk that highlights how important the dish is to daily life.
You will never struggle to find coffee in Seoul. The city has one of the highest concentrations of coffee shops in the world. But these are not just for quick espresso shots. You can visit cafes filled with sheep, raccoons, or meerkats. Some shops focus entirely on poop emojis or flower arranging. A coffee break here is often a full entertainment experience.
Duty calls for every South Korean man. All male citizens between the ages of 18 and 35 must join the military. They serve for roughly 21 months. This rule applies to everyone. Even famous actors and K-pop idols pause their careers to enlist. It is a shared experience that bonds men across the country.
You may have seen Taekwondo in the Olympics. This famous martial art started right here in Korea. It is more than just a sport. It is a way of life that teaches discipline and mental strength. Many Korean children attend academies after school to earn their black belts. You can even watch authentic demonstrations at cultural centers in Seoul.
Look closely at the cars driving past you. You might spot small blue foam sponges stuck to the doors. Car factories put these on to prevent damage during shipping. But many Korean drivers leave them on forever. Parking spots are tight in the city. The sponges stop their doors from dinging the car next to them.
Night owls will love it here. The streets stay alive long after midnight. You do not need to rush to finish your dinner. Many restaurants and cafes in South Korea stay open until 4 a.m. or later. You can go shopping, grab a coffee, or sing karaoke while the rest of the world sleeps. The energy in the city truly lasts all night long.
