South Korea Exports Surpass Japan in H1 2026: Why

In international comparison reports for the first half of 2026, South Korea's exports surpassed Japan's. The gap in integrated circuit exports was larger than the overall gap. However, this does not mean that South Korea ranked first in global exports or that Japan's economy collapsed.

The comparison figures are based on first-half totals reported on August 7, 2026.

Export Comparison for South Korea, Japan, and Taiwan

Based on the same report, South Korea's exports were $111.9 billion higher than Japan's. Taiwan also recorded higher exports than Japan. South Korea's first-place ranking here is among the three economies being compared.

ET News cited an analysis by the Nihon Keizai Shimbun (日本経済新聞). The analysis used national trade statistics and international trade data. According to the report, this was the first time South Korea and Taiwan surpassed Japan in first-half exports. ET News report dated August 7, 2026

The number of digits in these amounts must be corrected. Writing South Korea's exports as $49.63 billion gives one-tenth of the figure in the actual report. The figures of $38.44 billion for Japan and $41.66 billion for Taiwan contain the same error.

Why Do the South Korean Government Announcement and the International Comparison Report Differ?

The South Korean government announcement and the international comparison report contain different figures. The Ministry of Trade, Industry and Energy's July 1 announcement puts first-half exports at $496.7 billion. This was an increase of 48.4% year over year.

The difference between the two figures is $400 million. The documents reviewed do not provide enough information to determine the reason for the difference. The original statistics must be checked for the timing of the totals or whether revisions were made.

The government announcement is available from the KDI Economic Information and Education Center. (Confirmed figures: South Korea's exports in the first half of 2026 were $496.7 billion, up 48.4% year over year; semiconductor exports were $192.4 billion; exports of non-semiconductor products increased 16% · Source: eiec.kdi.re.kr · Confirmed on 2026-07-01) The document is titled "Export and Import Trends for June and the First Half of 2026."

Calculation Example: What Happens When Integrated Circuits Are Excluded?

If integrated circuits are excluded from the same international comparison figures, Japan comes out ahead. This is because the gap in integrated circuits is larger than the overall gap. The calculation below is a simple breakdown of the reported figures for the first half of 2026.

The calculations are as follows.

• South Korean exports excluding integrated circuits: $496.3 billion - $149 billion = $347.3 billion
• Japanese exports excluding integrated circuits: $384.4 billion - $21.2 billion = $363.2 billion
• Overall gap: integrated circuit gap of $12.78 billion - gap of approximately $1.6 billion in other products = $11.19 billion

This calculation supports the interpretation that integrated circuits were central to the reversal in export rankings. However, it does not calculate the net contribution of AI or HBM. This is because not all integrated circuits are HBM.

The comparison excluding integrated circuits also does not determine which country won or lost across all industries. Excluding a particular flagship product removes each country's strengths from the comparison. This calculation is intended to show how concentrated the export structure is.

Impact of AI Semiconductors on Exports

Growing demand for AI semiconductors was a major factor behind this export gap. A report shared by the Korea International Trade Association highlighted South Korea's memory production base. In Taiwan, semiconductor production centered on TSMC drew attention.

In the first half of 2026, South Korea's integrated circuit exports were $14.9 billion. Taiwan recorded $133.2 billion during the same period. Japan's figure for the same category was $2.12 billion. Export comparison report posted by the Korea International Trade Association

HBM is high-bandwidth memory made by vertically connecting multiple DRAM chips. Its core function is to transfer large amounts of data quickly. SK hynix describes it as high-performance memory for AI. SK hynix explanation of HBM technology

However, the scope of the export statistics must be distinguished.

The Ministry of Trade, Industry and Energy announcement put first-half semiconductor exports at $192.4 billion. The same announcement said that non-semiconductor exports also increased 16% year over year. It is therefore incorrect to interpret this as meaning that exports from all other industries were stagnant.

The figures of $192.4 billion and $149 billion for integrated circuits come from separate totals. The entire difference should not be treated as the export value of a particular product. An accurate comparison requires checking product codes and the scope of items included.

Has Japan Given Up on Semiconductors?

There is insufficient evidence to conclude that Japan has given up on the semiconductor industry. Japan led the economies in the comparison in exports of semiconductor manufacturing equipment. Government support for advanced semiconductor manufacturing technology is also continuing.

Japan's equipment exports of $15 billion are smaller than its integrated circuit exports of $2.12 billion. The calculation that equipment exports were seven times integrated circuit exports does not hold. This error occurs if the integrated circuit figure is incorrectly written as $2.12 billion.

Japan's strength in equipment may be linked to expanding production in South Korea and Taiwan. This is because semiconductor production requires manufacturing equipment. However, equipment orders and chip sales do not increase at the same pace or at the same time.

Japan's Ministry of Economy, Trade and Industry announced support for Rapidus on April 11, 2026. The supported areas include the development of advanced logic semiconductor manufacturing technology. They also include the development of packaging design and manufacturing technology for the 2nm generation. Ministry of Economy, Trade and Industry announcement on increasing Rapidus's research and development budget

It is therefore incomplete to say that Japan remained limited to equipment and materials. Conversely, an investment announcement does not mean that competitiveness in mass production has been secured. Actual results must be confirmed through production performance and customer acquisition.

Can the Export Gap Be Explained by the Weak Yen Alone?

Exchange rates have an impact, but export values alone cannot isolate its size. If the yen-denominated amount remains the same, a weaker yen reduces the amount when converted into dollars. In actual exports, contract prices and sales volumes also change.

The basic relationship for dollar conversion is as follows.

• Dollar-denominated export value = yen-denominated export value ÷ yen exchange rate per dollar
• For the same yen amount, a higher yen exchange rate per dollar results in a smaller dollar-denominated amount.
• Estimating the actual exchange-rate effect requires checking exchange rates and export prices for each period together.

The fact that the South Korean won and Taiwan dollar were also weak does not by itself rule out exchange-rate effects. This is because the degree of depreciation may differ between currencies. Export products are also priced differently.

The Bank of Japan explains effective exchange rates, which also account for trading partners. The real effective exchange rate also reflects differences in prices between countries. This is why price competitiveness is difficult to assess using only the exchange rate against the dollar. Bank of Japan explanation of effective exchange rates

The definition of the indicator must also be considered when checking export volumes. The Bank of Japan publishes real export data with price fluctuations removed. Specifying a period of stagnation without separately verifying the time series can lead to errors. Bank of Japan data on real exports and real imports

How Do Export Value and Domestic Value Added Differ?

Export value is not the same as value newly created domestically. Exported products may include raw materials and components imported from overseas. The OECD's trade in value added statistics distinguish the value added by each country. OECD explanation of trade in value added

This distinction is useful when examining the semiconductor supply chain. Materials and components from multiple countries may go into a single product. The value of goods sold across borders should therefore not be treated as domestic income.

A company's nationality must also be distinguished from where its exports occur. Sales from an overseas factory in the local market are counted differently from exports from the home country. This is why export rankings alone make it difficult to assess the global scale of a company's operations.

From this perspective, it is difficult to reduce South Korea and Japan to simple winners and losers. Growth in South Korean chip exports may be linked to revenue for Japanese suppliers. Industrial competition and supply chain cooperation can exist at the same time.

Common Mistakes: What Can Export Rankings Tell Us?

A reversal in export rankings must be interpreted only within the specific period and indicator involved. A first-half merchandise export ranking is not a ranking of entire economies. Past policies or events should not immediately be identified as the cause.

The 2019 South Korea-Japan export control dispute forms part of the policy background to the supply chain. Japan's Ministry of Economy, Trade and Industry discloses the measures taken at the time and subsequent policy dialogue. However, whether that dispute caused the current gap requires separate verification. Ministry of Economy, Trade and Industry timeline of export controls toward South Korea

Abenomics and the collapse of the bubble economy also do not directly explain these figures. Long-term industrial change and the performance of a single half-year involve different analysis periods. Evidence connecting historical background to current export performance is needed before it can be cited as a cause.

Criteria for Determining Whether the Export Lead Will Continue

To assess whether the lead will continue, semiconductor demand and the export structure must be considered together. Growth in nominal export value alone cannot confirm an increase in sales volume. For future comparisons, check the following in order.

1. Align the periods and currency units used in each country's statistics.
2. Check whether the data are preliminary or revised.
3. Distinguish the product scope of integrated circuits from that of semiconductors as a whole.
4. Check export prices and volumes separately.
5. Compare growth in non-semiconductor products as well.
6. Distinguish companies' actual production results from their forecasts.

Claims that the boom will continue through 2027 or 2028 are forecasts. When citing a forecast, the issuing organization and date must be disclosed. Its assumptions about supply and demand must also be presented.
