On September 1, 2025, private surveys revealed that factory activity in Japan, South Korea, and Taiwan contracted in August, with S&P Global’s Purchasing Managers’ Index (PMI) showing Japan’s PMI at 49.7, South Korea’s at 48.3, and Taiwan’s manufacturing weakened, all below the 50 threshold indicating contraction. The downturn, driven by U.S. tariffs, including a 15% rate on Japanese and South Korean goods effective August 1, follows trade deals that reduced tariffs from 27.5% and 25%, respectively, but failed to eliminate export pressures. Taiwan faces a 20% tariff on non-semiconductor goods, exacerbating challenges for its export-reliant economy. Meanwhile, China’s RatingDog PMI rose to 50.5, reflecting a rush to ship goods before higher tariffs. These tariffs, part of President Trump’s trade policy, have raised the U.S. average tariff rate to 20.4%, contributing to a projected 1% global trade volume contraction, per the World Trade Organization. This news warrants a full impact analysis across state and local governance, national governance and politics, economy and trade, international relations, and people’s daily life and society.
Impact Analysis:
1.Impact on State / Local Governance
Economic strain on tech hubs: Regions in Japan, South Korea, and Taiwan hosting manufacturing facilities may face reduced local tax revenues due to factory slowdowns, limiting funds for public services like infrastructure.
increased support programs: Local governments may need to expand subsidies or job training to offset manufacturing job losses, with South Korea’s government already proposing budget increases to counter tariff impacts.
2.Impact on National Governance & Politics
Policy adjustments: Japan and South Korea may push for domestic stimulus, like South Korea’s proposed budget hike, to offset export declines, while Taiwan may seek new trade agreements to diversify markets.
Political pressure: Governments face criticism for failing to secure better U.S. trade terms, potentially weakening ruling parties like Taiwan’s Democratic Progressive Party ahead of elections.
3.Impact on Economy & Trade
Export revenue losses: Japan’s exports to the U.S., valued at $145.76 billion in 2024, and South Korea’s $127.8 billion face declines, with Japan’s GDP projected to drop 0.1% by 2026 due to tariffs.
Supply chain disruptions: Taiwan’s semiconductor industry, despite tariff exemptions, faces indirect pressures from reduced global demand, potentially raising chip prices by 10–15%.
Consumer price hikes: Tariff-driven cost increases could raise electronics prices globally, adding $1,200–$2,800 annually to household tech costs in affected regions.
4.Impact on International Relations
U.S.-Asia tensions: The 15–20% tariffs strain U.S. relations with Japan, South Korea, and Taiwan, with South Korea’s trade minister seeking negotiations to reduce nontariff barriers.
Regional cooperation: China, Japan, and South Korea’s March 2025 trade talks signal efforts to counter U.S. tariffs through a trilateral free trade agreement, potentially shifting regional trade dynamics
5.Impact on People’s Daily Life & Society
Rising living costs: Higher tariffs may increase prices for imported goods like electronics and vehicles, squeezing household budgets in Japan, South Korea, and Taiwan.
Job insecurity: Manufacturing slowdowns, with South Korea’s PMI at 48.3 for seven months, could lead to layoffs, particularly in export-driven sectors like automotive and electronics.

Largest Impact Area: Economy & Trade
The economy and trade sector will likely face the largest impact due to the direct hit from U.S. tariffs on export-dependent economies. Japan’s $145.76 billion and South Korea’s $127.8 billion in U.S. exports are at risk, with Japan’s GDP projected to decline 0.1% by 2026. Taiwan’s manufacturing faces a 5% production value drop if tariffs fully apply. The 10–15% rise in electronics prices could add $1,200–$2,800 to household costs, and global trade volumes may shrink by 1%, per the World Trade Organization, making this the most critical impact area.
Conclusion: U.S. tariffs are shrinking factory activity in Japan, South Korea, and Taiwan, disrupting global trade and raising costs. Policymakers must address these challenges to stabilize economies and maintain regional cooperation.
