Today, October 9th is Hangul Day (한글 날, Korean Alphabet Day ). Happy Hangul Day ~

Today is October 9th, Hangul Day, a national holiday when Korea celebrates its alphabet.

The sky was high and clear, the air was crisp, and it felt like a crime to stay indoors. So I headed to the National Hangeul Museum in Seoul.
What better way to spend Hangul Day than at the museum devoted to Hangul itself ?

But, the doors were closed !

In February 2025, a fire broke out at the museum while it was shut for an expansion project. The damage was serious enough that repairs will keep it closed until October 2028 !
Fortunately, no one was seriously hurt, and the museum’s collection of roughly 89,000 items had already been moved to safe storage at the National Museum of Korea and the National Folk Museum of Korea.
That was a relief, but it didn’t change the fact that I had made the trip for nothing.

A Detour That Turned Out Fine

The Hangeul Museum sits right next to the National Museum of Korea, so I wandered over there instead.
I ended up sitting on a bench for a long while, watching the autumn light fall across the grounds, and then I strolled around the entire museum complex at a leisurely pace.

I never actually went inside. The crowds were enormous, and I didn’t have the energy to join them.
When I got home and looked into it, I understood why.  According to The Art Newspaper’s 2025 museum visitor survey, the National Museum of Korea welcomed more than 6.5 million visitors in 2025.
That ranks it third in the world, behind only the Louvre and the Vatican Museums, and ahead of the British Museum and the Metropolitan Museum of Art in New York.
The survey also noted that the most striking growth anywhere was in Korea, where the museum’s visitor numbers jumped by more than 70% in a single year.

I couldn’t get past the crowds, but I left oddly proud of them. People from all over the world are coming to see Korean culture, and I was lucky enough to spend my afternoon on a bench in the middle of it.

Since the Hangul Museum was closed, let me tell you its story myself.

A Language Without a Script

For most of its history, Korea had a problem : the Korean language existed, but Korean writing did not.

Koreans had been speaking our own language for thousands of years, but we had no alphabet of our own.

To write anything down, we borrowed Chinese characters, known in Korean as hanja.
This was a poor fit. Chinese and Korean are completely different languages, with different grammar and different sounds.

Worse, Chinese characters take many years to master, and there are thousands of them. Only the wealthy and educated elite had the time and resources to learn them. For ordinary farmers, merchants, and women, reading and writing were out of reach.
If you had a grievance to report or a letter to send, you often had to find someone else to write it for you.

The King Who Felt Sorry for His People

King Sejong, the fourth king of the Joseon dynasty, saw this problem and decided to fix it.
According to the Annals of the Joseon Dynasty, the alphabet was completed in December 1443. In September 1446, it was officially announced to the public under the name Hunminjeongeum, meaning “The Correct Sounds for the Instruction of the People.”

His own words explain why. In the preface, he wrote that many ordinary people had things they wanted to say but could not express them in writing, and that he felt sorry for them. So he created twenty-eight new letters that everyone could learn easily and use comfortably in daily life.

Not everyone welcomed this at first.
Some scholars at court protested, arguing that Chinese characters should remain the proper way of writing.
But the king persisted. A writing system designed not to serve the powerful but to serve ordinary people was a radical idea, and it still feels remarkable nearly six centuries later.

Why Hangul Is So Easy to Learn

 

So what makes Hangul so different ?
Its letters are not arbitrary symbols. They were designed to look like the way you make the sounds.

The result is an alphabet you can learn at astonishing speed.
The scholar who wrote the preface to the original explanation of Hangul famously boasted that a wise person could learn it before the morning was over, and even a slow learner within ten days.
Many language learners today will tell you it isn’t far from the truth.

What makes Hangul even more unusual is that it is one of the very few writing systems in the world where we know exactly who created it, when, and why. The explanation survives in a book called the Hunminjeongeum Haerye, which was rediscovered in 1940 and was inscribed on UNESCO’s Memory of the World Register in 1997.

The Result : A Nation That Reads

The effect on Korea has been profound.
Today, Korea has one of the highest literacy rates in the world, and illiteracy is practically unknown among younger generations.
When the writing system is this easy to learn, almost everyone can read.

The world has noticed. UNESCO has awarded the King Sejong Literacy Prize every year since 1989 to honor groups and individuals fighting illiteracy around the world. Few writing systems can claim that kind of legacy.

Koreans ourselves honor the king by calling him Sejong the Great, and he is widely regarded as the most beloved ruler in Korean history.
In the heart of Seoul, a large bronze statue of him sits in Gwanghwamun Square, right in front of Gyeongbok Palace. 

Beneath the statue, an underground exhibition hall called “The Story of King Sejong” tells the story of his life and his achievements.

Hangul Day, and a Special Year

2026 is an especially meaningful year. It marks the 580th anniversary of Hunminjeongeum, the 100th anniversary of Hangul Day’s observance, and the 100th anniversary of Hunmaengjeongeum, the Korean braille system created for visually impaired readers.

The World Wants to Learn Korean

Perhaps the most delightful part of this story is what is happening now.
All over the world, young people are rushing to learn Korean.

It started with K-pop and K-dramas, and for many, it grew into something deeper. People who began watching with subtitles now want to understand the words without them.
The numbers are striking. The King Sejong Institute, the government-backed network of Korean language schools around the world, named after the king himself, recorded more than 230,000 learners in 2025, an all-time record.
And the number of people taking the Test of Proficiency in Korean (TOPIK) reached about 550,000 by September 2025, the highest since the test began in 1997.
In addition, many people from developing countries are studying Korean intensively so that they can come to Korea to work.

Think about that. A writing system created 580 years ago for the farmers of one small kingdom is now being studied by teenagers in Paris, Hanoi, Mexico City, and Cairo, on their phones, on the way to school.

Why Hangul Is Powering Korea in the AI Era

What moves me even more as a modern blogger is seeing how an invention from 1446 fits the 21st-century digital landscape with absolute perfection.

And, as a grandma who loves Hangul but isn't a tech genius, I asked AI to explain the computational beauty of our alphabet.

• Syllabic Blocks and Binary Logic : Hangul characters are not strung out in long linear lines ; rather, an initial consonant, medial vowel, and optional final consonant assemble into neat, modular square blocks.
  This architectural layout maps intuitively onto modern computing data structures and pixel grids.

• A Natural Advantage for Artificial Intelligence : Because each character maps reliably to a consistent phonetic sound with rigorous rule-based logic, Large Language Models (LLMs) and speech-recognition engines process Hangul text with exceptional computational efficiency.
  Machine learning pipelines find fewer phonetic anomalies compared to scripts burdened with irregular spelling conventions.
  

Anyway, I believe that a country with one of the world’s most scientific alphabets, a population that can read and write, and a culture that draws the world’s attention can go even further in this new age. 

Sitting on that bench in the autumn sun today, I felt that belief grow stronger.

The Hangeul Museum is scheduled to reopen in October 2028.
When it does, I’ll be first in line. Until then, I’ll keep celebrating Hangul Day every year, and keep an eye on those crowds next door.

A Video from a Past Hangul Day

The museum was closed today, but a few years ago, on another Hangul Day,
I visited and recorded a short video inside. While we wait for the doors to reopen, here it is. => https://youtu.be/TSPijXQggOQ?si=zHXPhNv-GN9c1DLU
