The Concrete Memory
Walk through the streets of Taipei, and you will eventually find yourself standing before the Presidential Office Building. Its red-and-white brickwork is imposing, a neo-Renaissance structure that feels like it belongs in a European capital rather than a subtropical island. For a casual tourist, it is a backdrop for a selfie. For a resident of Taipei, it is the seat of power. But for Beijing, this building is a scar that refuses to heal.
It was built by the Japanese.
Between 1895 and 1945, Japan held Taiwan as a prize of war. They built the railways. They structured the schools. They laid the foundations of the modern electrical grid. They also suppressed local culture and pushed a policy of "Kominka," aiming to turn the island’s inhabitants into loyal subjects of the Emperor.
When Taiwan’s President William Lai stepped out recently to commemorate the 100th anniversary of the Tainan Canal—another Japanese engineering feat—he wasn't just talking about water and logistics. He was touching a live wire. By praising the craftsmanship and the shared history of the canal, Lai triggered a seismic response from the Taiwan Affairs Office in Beijing. To the mainland, every word of gratitude toward a colonial past is a betrayal of "Chinese blood."
It is a fight over a ghost.
Two Ways to See a Canal
Consider an elderly man in Tainan. Let’s call him A-Gong. He remembers his father talking about the day the canal opened. To A-Gong, the canal isn't an abstract symbol of imperialist aggression. It is the reason his grandfather’s crops didn't rot. It is the reason the city breathed. His relationship with the Japanese era is messy, layered with both the memory of secondary citizenship and the appreciation for the sudden leap into the twentieth century.
Beijing views this nuance as a toxin.
The official narrative from the mainland is clear: the Japanese occupation was a period of unmitigated suffering and humiliation. To suggest otherwise is to "glorify" a thief who broke into your house and reorganized your furniture. When William Lai speaks of the "shared heritage" between Taiwan and Japan, Beijing hears a leader trying to cut the umbilical cord that connects Taiwan to the Chinese motherland.
If you can convince a people that their "golden age" or their "modernization" came from a source other than China, you have effectively won the psychological war for independence.
The Invisible Stakes of a Speech
The rhetoric from the Taiwan Affairs Office wasn't just a polite disagreement. It was a condemnation of "de-Sinicization." This is the real battlefield. It isn't fought with missiles, at least not yet. It is fought with textbooks, museum exhibits, and anniversary speeches.
Beijing’s fear is that Taiwan is building a "New Taiwanese" identity that is distinct, maritime, and inclusive of its colonial layers. If Taiwan is a fusion of indigenous roots, Dutch trade, Japanese infrastructure, and Chinese heritage, then it becomes something entirely its own. A unique entity. A country.
But if Taiwan is merely a province waiting to be "recovered," then the Japanese era must be framed solely as a dark interruption.
Lai’s strategy is subtle. By leaning into the Japanese connection, he is reinforcing a "First String" of democratic allies. Japan and Taiwan today share more than just historical infrastructure; they share a deep-seated anxiety about the rise of an assertive China. When Lai honors a Japanese engineer like Hatta Yoichi—the man behind the Great Kanan Canal—he is signaling to Tokyo that Taiwan remembers its friends.
The Language of Betrayal
The words used by Beijing officials were pointed: "Seeking independence by clinging to Japan."
They see Lai’s rhetoric as a psychological bridge. If you praise the bridge, you might want to cross it. The mainland’s logic follows a straight line: acknowledging any benefit from the Japanese era equals "Japan-worship," which equals "separatism," which equals "treason."
The emotional core of this dispute is a deep, historical insecurity. China’s "Century of Humiliation" began with foreign powers carving up its territory. Japan was a primary architect of that pain. For Beijing, seeing a Chinese-speaking leader on an island they claim as their own, thanking the very power that once humbled the Middle Kingdom, is a visceral insult.
It feels like watching a family member praise the person who bullied you in high school.
The Reality on the Ground
But go back to the streets of Tainan.
The people living there aren't thinking about the 1895 Treaty of Shimonoseki every time they turn on a tap or walk past a colonial-era station. They are living in a vibrant, noisy democracy that has moved past the trauma of the mid-twentieth century to create a high-tech powerhouse.
Taiwanese identity is not a zero-sum game. It is a palimpsest—a parchment where the old writing has been scraped off, but the traces remain beneath the new. You can hate the colonizer’s boot while still appreciating the road he paved.
William Lai knows this. He is betting that the people of Taiwan are comfortable with their complexity. He is betting that they can look at a Japanese canal and see it as part of their story, not Japan’s story and certainly not Beijing’s.
The Silence Between the Lines
What remains unsaid in these diplomatic shouting matches is the most important truth of all: the people of Taiwan are the only ones who actually have to live inside this history.
Beijing’s statements are often directed inward, to a domestic audience that must be kept in a state of righteous indignation. Lai’s statements are directed outward, to a global community that needs to see Taiwan as a distinct, civilized, and historically rich partner.
The canal flows on. It doesn't care about the press releases. It doesn't care about the accusations of "glorifying" ghosts. It carries water, just as it did a century ago.
But the air above the water is heavy. Every time a politician reaches back into the past to grab a handful of history, they risk pulling up a handful of thorns. The struggle isn't over who built the canal, but over who owns the right to tell the story of the water.
In the end, the most dangerous thing you can do in this part of the world is remember the wrong thing. Or worse, remember the right thing at the "wrong" time.
The sun sets over the Tainan Canal, casting long shadows from buildings that were designed in Tokyo, built by Taiwanese hands, and are now claimed by a government in Beijing that has never governed a single inch of the island's soil. The shadows are long, but they are just shadows. The people on the banks are already moving toward tomorrow, carrying the weight of a past that no one can agree on, under a sky that belongs to no one.
