South Korea and Taiwan have surpassed Japan in total export value for the first time in history, powered by explosive demand for artificial intelligence semiconductors that has fundamentally reshaped Asia’s trade hierarchy.
According to an analysis released on August 7 by Japan’s Nikkei Shimbun, conducted with Mitsubishi UFJ Research and Consulting using trade statistics from all three economies plus UN and JETRO data, South Korea’s first-half exports reached $496.3 billion and Taiwan’s hit $416.6 billion. Japan’s exports, despite rising nearly 10% year-on-year, came in at just $384.4 billion, falling behind both rivals for the first time.
The AI Semiconductor Gap
The divergence is stark in semiconductor integrated circuits (ICs), the flagship product of the AI era. South Korea’s IC exports reached $149 billion in the first half, while Taiwan’s totaled $133.2 billion. Both countries now export ICs worth roughly 30% of their total outbound shipments. Japan’s IC exports, by contrast, stood at just $21.2 billion, representing only about 5% of its total exports.
South Korea’s overall ICT exports hit a record $253.9 billion in the first half, up 120.5% from a year earlier, with semiconductor exports alone surging 162.5% to $192.4 billion. The boom was driven by strong demand for high-bandwidth memory (HBM) chips used in AI servers, with Samsung Electronics and SK Hynix leading global supply.
“Countries are significantly increasing their semiconductor exports, but export value for equipment and materials is difficult to increase as sharply as for final products,” said Kenta Maruyama, a researcher at Mitsubishi UFJ Research and Consulting.
Japan’s Specialization Limits
Japan remains a global leader in semiconductor materials, parts, and equipment, with manufacturing equipment exports reaching $15 billion in the first half, far exceeding South Korea’s $5.2 billion and Taiwan’s $3.5 billion. However, these upstream products cannot match the value of finished chips in a rapidly expanding AI market.
The Nikkei noted that the weak yen is not the primary explanation for Japan’s relative decline, since the Korean won and Taiwan dollar have also weakened against the dollar. The structural difference lies in who produces the high-value advanced semiconductors that AI developers are racing to secure.
Taiwan’s dominance stems from TSMC, which fabricates the most advanced AI processors, while South Korea’s Samsung and SK Hynix control the memory chip market critical for AI training infrastructure. Together, these companies have driven their respective nations to new export heights, with South Korea’s June exports alone topping $100 billion for the first time.
The shift carries geopolitical implications. As AI becomes central to economic and military competition, the concentration of advanced chip production in just two economies raises supply chain vulnerability questions for both the United States and Europe, which depend heavily on Asian semiconductor output.
