AI Chip Export Boom: South Korea and Taiwan's Exports Surpass Japan for the First Time
Alina Collins
In the first half of 2026, South Korea and Taiwan each exported more than Japan for the first time, driven by AI chips. Integrated-circuit exports from both economies grew nearly 50% year-on-year versus Japan's roughly 10% — a gap that points not to exchange rates but to who controls high-end chip mass production.
How wide is the gap?
South Korea exported $496.3 bn in the first half, Taiwan $416.6 bn, Japan $384.4 bn — South Korea and Taiwan each grew nearly 50% year-on-year while Japan managed only about 10%.
This means → the lead is not marginal. Within a single half-year, both economies opened a hundred-billion-dollar-class gap over Japan.
In plain terms = all three are export powerhouses, but South Korea and Taiwan caught the strongest wave of AI chip demand. Japan did not.
How much did chips actually contribute?
South Korean integrated-circuit exports hit $149 bn in the first half; Taiwan's reached $133 bn — roughly 30% of each economy's total exports.
Japan's IC exports totaled just $21.2 bn, about 5% of its export total.
This means → chips alone account for the bulk of the South Korean and Taiwanese export surge. South Korea's first-half chip exports already exceed its full-year 2025 figure — a sign that AI demand is outrunning historical pace.
Where does Japan's strength lie?
Japan leads in semiconductor manufacturing equipment and materials. Tokyo Electron, Advantest, and Laser Technology hold top global positions; first-half equipment exports reached $15 bn, far above South Korea's $5.2 bn and Taiwan's $3.5 bn.
Equipment and materials sit upstream, however, and that market expands far more slowly than finished chips.
In plain terms = Japan sells the machines that make chips; South Korea and Taiwan sell the chips themselves. The machine market grows slowly; the chip market is surging — that is the source of the gap.
Can the yen's weakness explain this?
A weaker yen does shrink Japan's exports in dollar terms, but the Korean won and the New Taiwan dollar also weakened against the greenback over the same period. Currency alone cannot account for the divide.
The deeper signal: Japan's export-volume index has been flat since peaking before the 2008 global financial crisis.
This reflects a structural supply shortfall in the end-product categories where global demand is strongest — not "selling cheap" but "unable to scale volume."
Can this pattern reverse?
Kenta Maruyama of Mitsubishi UFJ Research and Consulting noted: "Even if global chip exports grow, shipments of materials and manufacturing equipment are unlikely to keep pace quickly."
This means → Japan's upstream advantage does not automatically convert into export growth unless it closes the gap in downstream finished-chip production.
In plain terms = this is not a one-quarter fluctuation — it is an AI-driven shift in industrial gravity. Whoever can mass-produce high-end chips captures the largest share of the export boom.
