Trip to Japan Before Enlistment

In July 2023, just a week before I was set to enlist, I took a solo trip to Japan.

I flew from Seoul to Incheon,
and with a JR Pass in hand, rode the Shinkansen through Tokyo, Yokohama, Kyoto, Osaka, Hiroshima, and Fukuoka.
From Fukuoka, I boarded a ferry bound for Busan,
and on my last day, I stopped by at a post office there to send all my luggage home.
After that, I caught a bus to Jinhae, home of the Navy Recruit Training Center,
stepped off at the main gate, and walked straight inside.

In Osaka, I caught COVID-19 and almost didn’t make it—
yet somehow, that week still turned out to be the most fun of my life.
Even visiting a Japanese hospital became a unique memory in its own way.

The next morning,


“Fifteen minutes to reveille.”

The Great Experiment

Many people refer to the founding of the United States as the greatest experiment in human history: a society built on liberty, equality, and popular sovereignty. There is merit to that claim. The United States took on the challenge of turning ideals into a functioning system of government, and over time, it became a land of opportunity for millions. Even today, it remains a symbol of hope for many around the world.

Roughly 170 years later, a different kind of experiment began on the Korean Peninsula.
After liberation from Japanese colonial rule, the South and the North adopted fundamentally different systems. The South chose capitalism and market economy, while the North turned to communism and a centrally planned economy. These systems differ at their core: capitalism prioritizes market autonomy and individual choice, while communism places economic control in the hands of the state.

The conditions for comparison were unusually clear.
The two sides shared the same ethnicity, language, and historical background. Their economic foundations were also comparable—if anything, the North had the advantage in industrial infrastructure and natural resources. In other words, the differences that emerged over time can largely be attributed to the systems they adopted.

Over the years, the two paths diverged.
South Korea pursued industrialization and education through a market-driven economy and opened itself to international exchange. Individuals were able to improve their lives through economic activity, and living standards steadily rose.

North Korea, on the other hand, placed nearly all economic activity under state control. The market was suppressed, and competition was limited. While the system produced some early results, its lack of flexibility became increasingly problematic. Over time, inefficiencies and resource shortages accumulated. Living standards stagnated, and the country became increasingly isolated from the outside world.

This was not merely a clash of ideologies.
It was a real-world demonstration of how different systems function when applied under nearly identical starting conditions. The structural differences between the two were most clearly reflected in the lives of the people who lived under them.

The outcome is relatively clear.
A system based on markets and individual choice was able to adapt and grow, while a system based on planning and control led to rigidity and isolation.
These differences are not theoretical—they are visible in the actual conditions of people’s lives.

The Korean Peninsula became one of history’s clearest testing grounds for that truth.

This experiment is still ongoing.
The Korean Peninsula remains divided, and each side continues to evolve under its respective system. But several decades of experience point to one clear conclusion:
When evaluating which system better supports human life, results matter more than ideals.
