The Thailand Board of Investment (BOI) reported that Japanese investment in 2025 has surged to over THB 100 billion, more than doubling year-on-year, driven by a recovery in Japan’s investment confidence index. Following discussions with the Japan External Trade Organization (JETRO) and the Japanese Chamber of Commerce, Japanese investors reaffirmed plans to continue expanding investment in Thailand in 2025.
Key drivers include the automotive, electronics, and digital industries, reflecting strong confidence in Thailand’s economic potential. This aligns with a Japanese Chamber of Commerce survey indicating an improved economic outlook this year, supported by a recovery in production and consumption from new business sectors.
Additional large Japanese investment projects in 2025 include aerospace components, high-quality steel production, food and beverage manufacturing, renewable energy, industrial estate development, and joint ventures. Some major automotive projects were also undertaken via Japanese subsidiaries based in Singapore.
The Secretary General of the BOI stated that despite heightened global uncertainty, Japanese investors remain confident in Thailand’s long-term potential and continue to view the country as a primary investment base. With over 6,000 Japanese companies operating in Thailand, Japanese investment more than doubled in 2025, with a clear shift toward new technologies such as hybrid vehicles, semiconductor assembly and testing, PCBs, aerospace components, biotechnology products, data centers, and renewable energy. The BOI will continue to strengthen cooperation with Japanese investors to upgrade domestic supply chains and enhance Thailand’s long-term economic competitiveness.
