Basic information for traveling to Korea

Republic of Korea (Hangul: 대한민국)

Seoul Metropolitan Government (Hangul: 서울특별시)

There is no time difference between Japan and Korea

Currency unit: Won (₩)

Approximately 88,520 won (April 24, 2024)

No visa is required for tourism, and your passport must be valid for at least 3 months.

Just like in Japan, there are four seasons, so choose clothes that suit the climate.

In addition to trains and planes connecting major cities, there are other means of transportation similar to those in Japan, such as buses.
Seoul has a subway system that makes getting around very easy.

The voltage of electrical outlets in Korea is 220V and in Japan it is 100V, so be sure to bring a Korean-compatible C-type plug or a transformer.

Generally, there is no tipping culture in Korea. If you want to give a tip, a small amount is enough, not a large amount.

A checklist of what to bring when traveling to Korea

Don't forget to bring a passport with at least three months remaining validity, and a copy in case you lose it.

When planning your trip to Korea, estimate how much it will cost. Also, the exchange rate is better in Korea, so it is recommended that you bring Japanese yen to Korea.

Don't forget to bring a credit card or debit card as cash alone is not enough.

A smartphone is essential when traveling to Korea, as it comes with map and translation apps.

You will need a plane ticket (if you are entering by plane) or a boarding ticket (if you are entering by ferry, etc.) to go to Korea.

There are various types of accommodation in Korea, including regular hotels, guesthouses, capsule hotels, private lodgings, etc. If you are not confident in your Korean language skills, it is better to choose a hotel run by a Japanese company.

Be sure to take out overseas travel insurance to prepare for any trouble you may encounter. You can get overseas travel insurance for as little as 1,000 yen, and if you have a credit card, check the additional insurance it comes with.

We recommend that you bring along the right medicine for you. Stomach medicine in case of spicy foods. Cold medicine and headache medicine in case of temperature changes. It is also useful to bring a compress when you get tired from walking.

The shape of the electrical outlets is different in Korea and Japan. Please purchase a conversion plug or electrical appliances that are compatible with Korea.

Some hotels do not provide disposable items, so you will need to bring them from Japan or purchase them at convenience stores in Korea.

Makeup remover and cleansing products are often forgotten when traveling to Korea. Of course, you can purchase them, but if you have sensitive skin, you should check carefully.

In Korea, toilet paper cannot be flushed down the toilet. Some toilets do not have heated toilet seats, so be sure to bring flushable wet tissues with you.

You may get caught in a sudden rain shower, so it's a good idea to bring a folding umbrella with you so it won't be a burden to carry.

You can charge it in cafes etc., but it's handy to have one. Bring one with you in case you can't use map apps or take photos.

Korea experiences large temperature fluctuations, so be sure to bring a jacket that is easy to carry and can protect you from sudden cold spells.

We recommend the WOWPASS or NAMANE card. These cards can be used for payments anywhere in Korea and also function as a transportation card, so they are a must-have card for your trip to Korea.

Must-try foods for your trip to Korea

Yakiniku (Samgyeopsal)

When it comes to Korean food, yakiniku is definitely the one to go for! Samgyeopsal and Mossal are especially popular!

Samgyetang (ginseng chicken soup)

This soup is made by stuffing chicken with Korean ginseng and herbal medicine and simmering it. The tender chicken meat and nutritious soup are very popular with people of all ages.


Kim (kin) means ride and pad means rice, a Korean style seaweed roll.

Cold noodles (naengmyeon)

Most restaurants offer cold noodles (with soup) and bibin cold noodles (without soup).


A hearty hotpot dish in which a whole chicken is simmered. The ingredients are very simple, such as green onions, potatoes, and mochi, but the chicken stock makes for a delicious soup!

Cheese Dak Galbi

Dakgalbi is a classic Korean dish of chicken and vegetables stir-fried with gochujang. If you eat it with melted cheese, the spiciness is reduced and it's super delicious!








Recommended apps for traveling to Korea


It also supports Japanese. Just put a pin on the place you want to go to and it will tell you how to get there in detail. For now, it's more convenient than Google Maps.


The Japanese translation performance is high. It can also translate photos and voice. This app is used by people studying Korean.

Kakao Taxi (KAKAO T)

It supports Japanese. Even if you don't speak Korean, you can call a taxi and the approximate fare will be displayed in advance. You can also enter the departure point and destination in advance, so you can travel with peace of mind.

Local payment & transportation card app

Be sure to download the WOWPASS and NAMANE card apps as well. By linking your card to the app, you can check your balance and usage history.

Useful Korean phrases to remember


If you say this to a taxi or bus driver, they will be happy. It also has the connotation of "engineer."


It means "older sister." Maybe you can become closer to the lady at the restaurant by calling her "Onni!" instead of "Chogyeo (excuse me)"?

I'm so happy

It means "I'll come again!" It's recommended to say this before leaving a store after having a delicious meal or making some great purchases.

Thank you very much

It means "Give me lots of things!" If you want more, try saying it and people will likely listen. It's important to say it in a friendly way!

Thank you very much

As you know, "arigatou gozaimasu" (thank you) means "thank you." If you remember to be grateful in any situation, your trip will be more enjoyable.

I like it

It means "I like it," "I like it," or "I agree," and can be used in a variety of situations. It's best to say it in a friendly and cheerful manner.
