K-Drama for Healing

Which Country Learns Korean the Most?

Have you ever paused a K-drama, replayed a single line three times, and thought, "I really want to understand this without subtitles"? You are not alone. Right now, a student in Ulaanbaatar, a teenager in Bangkok, and a retiree in Ohio are all practicing the same Hangul letters you are. But here is the question our community keeps asking: which country loves learning Korean the most?

The answer depends on how you count. If you count raw numbers, big countries like Vietnam and China win easily. But if you ask a fairer question, how many people learn Korean compared to the size of the population, a very different country rises to the top. Spoiler: it is Mongolia, and it is not even close.

Below, I rank countries per capita using the most recent official data, then look at the countries with the largest total numbers, and finally introduce the countries where Korean is growing fast. Then I want to hear from you.

The Big Picture: Korean Learning Is at a Record High

Before we compare countries, here is how big the Korean language wave has become:

How We Ranked: Why Per Capita Matters

Comparing a country of 3.6 million people with a country of 1.4 billion by raw numbers is not fair. So for our main ranking, I used one consistent official dataset and divided it by population:

An honest limitation: this measures people serious enough about Korean to study in Korea. It does not count people learning at home through apps, local classes, or K-dramas. Also, the published breakdown covers only the top five nationalities, so other countries could not be included in this ranking. Still, it is the fairest same-yardstick comparison I could find with 2025 data.

Part 1: The Per Capita Ranking

1. Mongolia: 425 per 100,000 people

Mongolia sent 15,270 students to Korea in 2025, from a population of about 3.59 million. That works out to about 425 students per 100,000 people, or roughly 1 in every 235 Mongolians. That is almost six times the rate of second-place Vietnam. Of those students, 10,570 were in degree programs and 4,700 in non-degree programs, which include language training. (Etoday)

Mongolia also holds a special place in Korean language history. The very first King Sejong Institute opened in Ulaanbaatar in 2007, when the whole network had just 13 locations and 740 students a year. (Ministry of Culture, Sports and Tourism) Today that network spans 273 institutes, and it all started on Mongolian soil.

What makes Mongolia special is that learners embrace both the language and the culture. A study of 45 Mongolian students in Korea found three main motivations: interest in the Korean language itself, the influence of Korean pop culture, and future careers. (IAFOR) Local media trace this interest back to dramas like Winter Sonata, and many Mongolian universities have opened Korean studies departments. (The UB Post)

There is a challenge, too. A 2025 study by Mongolian scholars notes that the number of Korean studies teachers has decreased, with 74 Korean language teachers at 11 universities. (The Review of Korean Studies)

2. Vietnam: 73.5 per 100,000 people

Vietnam sent 75,144 students to Korea in 2025, from a population of about 102.3 million, which works out to about 73.5 per 100,000 people. (Etoday) Vietnam is so strong that it appears in our scale ranking below, too.

3. Nepal: 42.6 per 100,000 people

Here is a country many readers may not expect. Nepal sent 12,784 students to Korea in 2025, from a population of about 30 million, or about 42.6 per 100,000 people. (Etoday) Korean is also a pathway to work: whole TOPIK-prep industries have grown in Kathmandu, and a 2025 Korean work-permit round for about 5,300 slots drew far more applicants than spaces. (Seoulz)

4. Uzbekistan: 40.4 per 100,000 people

Uzbekistan sent 15,786 students to Korea in 2025, from a population of about 39 million, or about 40.4 per 100,000 people. By raw numbers, it is now the third-largest source of international students in Korea, just ahead of Mongolia. (Etoday)

Uzbekistan is also growing fastest in schools: it added 68 schools with Korean classes in 2025, the largest increase in the world. Enrollment at its King Sejong Institutes rose from 1,873 in 2021 to 7,931 in 2024, before easing to 6,308 in 2025. (The Times of Central Asia)

5. China: 5.4 per 100,000 people

China sent the most students to Korea in 2025, 76,541, but with a population of about 1.4 billion, that is only about 5.4 per 100,000 people. (Etoday) This is exactly why per capita matters: the biggest number does not always mean the strongest passion.

Bonus: Per Capita in Local Schools

Using a different dataset, students learning Korean in their own country's schools, we can compare two more countries:

Part 2: The Biggest Korean-Learning Countries by Total Numbers

Per capita shows passion. Total numbers show scale. These countries have the largest communities of Korean learners:

Vietnam: The TOPIK Leader

Of the 566,665 TOPIK applicants worldwide in 2025, 85,896 came from Vietnam, the highest of any country where the test is held overseas. Starting in 2026, TOPIK scores are recognized in Vietnam's university admissions process, making it only the second place after Hong Kong to do so. (The Korea Times)

China: The Largest Student Pipeline to Korea

For 2025, China recorded 70,267 TOPIK (Test of Proficiency in Korean) applicants for the paper-based test (PBT), ranking second worldwide after Vietnam. This figure does not include internet-based testing (IBT) or the speaking test

China also has a long historical connection to Korea. Korean migration to Manchuria began in the late 19th century and grew during the Japanese colonial period. By 1945, about 2.16 million Koreans lived there. About 1 million returned home, and about 1.16 million who did not return became China's Korean ethnic minority, known as the Joseonjok. (Wikipedia (Korean))

Thailand: Korean in the College Entrance Exam

Thailand has grown from 133 schools in 2019 to 227 secondary schools teaching Korean as a regular subject, with more than 49,000 students as of 2025. That is more than 20% of all elementary and secondary Korean learners worldwide. (Etoday) Korean is also in Thailand's college entrance exam: in the 2023 exam, about 19.8% of second-foreign-language test-takers chose Korean, second only to Chinese. (Korea.net)

Japan: The Most Schools Teaching Korean

Japan had 576 elementary, middle, and high schools teaching Korean in 2025, the most of any country listed. (The Asia Business Daily) Japan also has deep roots: when TOPIK launched in 1997, Japan was one of only four countries where it was held. The number of Japanese students in those classes and Japan's 2025 TOPIK total are 49,290 applicants.

United States: Korean Grew While Other Languages Shrank

The US had 217 schools teaching Korean in 2023 (The Asia Business Daily) and added 21 more in 2025 (The Korea Herald). At the college level, total language enrollment fell 16.6% between 2016 and 2021, yet Korean rose 38.3%. (MultiLingual) About 20,000 US college students were studying Korean in 2021, the latest survey year. (Asia News Network)

Part 3: Where Korean Is Growing Fast

These countries do not yet have comparable data for a ranking, but Korean is clearly growing fast:

Outside classrooms, a summary of Duolingo's latest report lists Korean as the second-fastest-growing language in Argentina, Colombia, France, Germany, Mexico, Poland, and Spain (Duolingo Guides). This comes from a secondary summary, so it is [확인 필요] until checked against Duolingo's official report.

What the Data Really Tells Us

Looking across all these countries, I noticed two different reasons people learn Korean:

And honestly, most learners are a mix of both. A drama might open the door, and a dream might keep you walking through it. Mongolia shows this beautifully: love of the culture and hope for the future, living side by side.

There is also a sobering side. Despite all the growth, 131 King Sejong Institute designations were terminated between 2013 and August 2026, and in 2025, 12 institutes closed, more than the 11 newly designated that year. (The Korea Herald) Demand is real, but keeping classes running takes long-term support.

A Healing Thought for Every Korean Learner

When I read these numbers, I do not just see statistics. I see a young person in Ulaanbaatar packing a suitcase for Seoul, a Thai teenager studying for an entrance exam, and maybe you, sitting with a cup of tea and a favorite drama, repeating a line until it finally sounds right.

Mongolia teaches us something important: you do not have to be big to love something deeply. A small country can lead the world in passion. And the same is true for you. You do not need a classroom or a perfect plan to begin. A free app, a favorite drama, and ten minutes a day is a real start. The regret we feel later is rarely about the things we tried; it is about the things we kept postponing.
