Thailand and Japan are deepening their industrial relationship as both countries
reposition supply chains around advanced manufacturing, with Japanese companies 
submitting more than **US$11.72 billion in investment applications across 1,380 
projects between 2021 and mid-2026**, according to the Thailand Board of Investment.
The figure underscores Japan’s continuing importance to Thailand even as Chinese
investment has expanded rapidly in recent years.

## Key points

 * Japanese companies submitted **US$11.72bn of investment applications** for 1,380
   Thailand projects between 2021 and mid-2026.
 * Priority areas now include **semiconductors, AI computing, advanced electronics,
   EVs, robotics and renewable energy**.
 * Thailand and Japan are developing a **“BOI to IPO” programme** and bilateral 
   carbon-credit cooperation to deepen capital-market and green-finance links.

The latest Thailand-Japan Investment Forum in Bangkok marks a shift from the traditional
automotive-centred relationship toward a broader technology and clean-energy partnership.
Japanese companies are looking at advanced chips, optical data transmission, AI 
computing, next-generation vehicles and renewable power, while Thailand is seeking
to use Japanese manufacturing expertise to upgrade existing industrial ecosystems.

The strategy also aims to connect foreign investment more closely with Thailand’s
domestic capital markets. The BOI and Stock Exchange of Thailand are developing 
a **“BOI to IPO” corridor** designed to help Japanese operating subsidiaries and
their Thai partners access SET, mai and LiVEx listings. EXIM Thailand is simultaneously
expanding green, blue and sustainability-linked financing to support industrial 
decarbonisation and infrastructure investment.

The industrial relationship is particularly important for Thailand’s automotive 
sector. Japanese automakers are pursuing a “multi-pathway” strategy that combines
hybrids and internal-combustion vehicles with battery EV production, allowing them
to adapt to changing consumer demand while maintaining Thailand as a regional export
base. At the same time, advanced electronics and semiconductor investment is becoming
a larger part of the bilateral relationship.

The challenge for Bangkok is to ensure that the investment applications translate
into realised investment, technology transfer and stronger Thai supplier networks.
That is especially important as Thailand competes with Vietnam, Malaysia and Indonesia
for the same wave of high-value manufacturing projects. Japanese investors have 
also emphasised the need for predictable regulation, fair competition and continued
productivity gains.

**Why it matters:** Japanese investment remains one of Thailand’s most important
industrial anchors, but its composition is changing. The shift toward semiconductors,
AI infrastructure, EVs and clean energy could help Thailand upgrade its manufacturing
base—provided the country can turn investment applications into operating projects
and connect them to domestic firms.
