Why Johor Is the Answer to a Question Every Taiwanese and Japanese Manufacturer Is Now Asking

The question is the same whether it is asked in Taipei, Tokyo, or Osaka: if the United States imposes serious tariffs on our exports, what do we do?

For Taiwanese and Japanese manufacturers, this is no longer a theoretical exercise. Malaysia's reciprocal tariff rate was set at 19% in August 2025 following rapid negotiations — lower than the initial 24% proposed in April, lower than the 25% imposed in July, but still a structural shift from the near-zero baseline that defined the previous decade of trade. Semiconductor exports currently retain an exemption, but that exemption is under active review by the US Department of Commerce under Section 232. Nobody in the supply chain knows when it changes, only that it might.

The manufacturers who are thinking clearly are not panicking. They are asking a different question: where do we put the next production node?

Why This Is a Johor Story

The answer to supply chain diversification in 2026 is not simply "move to Southeast Asia." Vietnam has labour cost advantages but geopolitical complexity. Thailand has automotive depth but limited digital infrastructure. Indonesia has scale but regulatory friction. The Philippines has English-language talent but lacks the industrial ecosystem.

Johor has something none of the others have: Singapore next door.

For Taiwanese manufacturers whose customers are headquartered in Singapore — which describes a significant portion of the region's electronics and precision manufacturing supply chain — Johor is not a compromise. It is an upgrade. The Johor-Singapore Special Economic Zone, formalised in January 2025, means that a factory in Johor and a headquarters in Singapore are now part of the same coordinated regulatory framework. Goods, people, and capital flow between them under a streamlined system that no other cross-border zone in ASEAN offers.

The Numbers Behind the Decision

Johor recorded RM 102 billion in approved investments in 2025 — the highest of any Malaysian state, and a figure that would have seemed implausible three years ago. In Q1 2025 alone, foreign direct investment into Johor reached RM 27.4 billion, a RM 24 billion increase over the same period in 2024. The leading sources: Singapore, China, and Japan.

That Japan appears on this list is not accidental. Academic research on Japanese multinational corporations published in 2025 by RIETI — Japan's Research Institute of Economy, Trade and Industry — documented a clear pattern: Japanese firms facing rising geopolitical risk are diversifying production from China into ASEAN economies, with Malaysia among the primary beneficiaries. This is not a trend. It is a documented structural shift.

For Taiwanese manufacturers, the logic is even more direct. Taiwan exports approximately USD 60 billion annually to the United States, with semiconductors, electronics, and precision machinery dominant. Any tariff regime that makes Taiwan-origin goods less competitive in the US market has an immediate knock-on effect on every manufacturer in the supply chain. Johor, operating under a 19% tariff rate with semiconductor exemptions still in place, offers an alternative origin point that does not require abandoning Asia-Pacific entirely.

What the JS-SEZ Actually Offers

The incentive structure of the JS-SEZ is specific enough to be worth examining directly. Qualifying businesses in the zone access a 5% corporate tax rate for up to 15 years. Knowledge workers — engineers, designers, data scientists — pay a flat 15% personal income tax rate. This compares to a standard Malaysian rate of up to 30% and Singapore's top rate of 22%. The application window runs from 1 January 2025 through 31 December 2034.

The Invest Malaysia Facilitation Centre Johor, a one-stop investment centre involving over 30 federal, state, and local government agencies, has processed more than 400 investor enquiries and secured RM 16.7 billion in committed investments since opening in early 2025. The centre exists specifically to remove the bureaucratic friction that historically made Malaysian market entry slow. It is working.

Lee Ting Han, Johor's State EXCO Member for Investment, Trade, Consumer Affairs and Human Resources, put the strategic case at the Fortune Innovation Forum in November 2025: "Special matters require execution." His point was that the JS-SEZ is not a vision document. It is a ten-year legally backed framework with committed infrastructure, coordinated government support, and a bilateral relationship between two stable governments that both need it to succeed.

The Taiwan-Johor Connection That Already Exists

Taiwan and Johor have more existing commercial linkage than most people in either place realise. Taiwanese precision manufacturers, electronics firms, and food and beverage companies have been present in Johor's industrial parks for decades. The DCITN — the Dual City International Trade and Investment Network — exists precisely to formalise and deepen these ties. The question now is whether manufacturers who have been watching from a distance decide that 2025 was the year the argument became unanswerable.

The parallel for Japanese companies is the supply chain data. With 80% of Johor's 2025 FDI coming from foreign sources and Japan among the top three origin countries, the decision is already being made at the corporate level. The companies announcing are not sharing the strategy publicly. But the investment flows do not lie.

The Practical Question

For a Taiwanese or Japanese manufacturer evaluating Johor seriously, the practical questions are straightforward: Which of the nine JS-SEZ flagship zones matches our sector? What is the minimum operating expenditure threshold for the 5% tax rate? How does the single-clearance immigration system at the RTS Link reduce staffing friction for managers commuting from Singapore?

These are implementation questions, not strategic ones. The strategic question — whether Johor belongs in a serious supply chain diversification plan for manufacturers with US market exposure — has already been answered by the RM 102 billion that arrived in 2025.

Lee Ting Han's projection for 2025: RM 100 billion. The actual figure: RM 102 billion. Execution is the word he used. It is also the result.
