How Can Taiwanese Investors Ride the Wave of Japan's Semiconductor Boom?

The arrival of Taiwan’s tech giant, TSMC, has breathed new life into Japan’s semiconductor industry. Once a source of national pride, Japan’s semiconductor sector had lost its luster over time. However, TSMC’s entry has rekindled hope and momentum, much like a spark reigniting a flame.

 

Why Did TSMC Choose Japan?

As early as 2021, the Japanese government introduced substantial subsidies to attract global semiconductor manufacturers. TSMC chose Kumamoto after carefully evaluating factors such as land availability, power supply, supply chain maturity, and local government support. The region’s proximity to key clients like Sony and Renesas, along with its well-established electronics components ecosystem, made it a strategic choice.

TSMC’s presence has also spurred infrastructure upgrades in Kumamoto, improving transportation, power networks, and overall living standards. More than just building a wafer fab, TSMC and the Japanese government are collaboratively shaping a new semiconductor ecosystem. This model is now being replicated in other regions, with Hokkaido emerging as the next key battleground.

 

Hokkaido: Japan’s Next Semiconductor Hub

By the end of 2024, TSMC announced further collaboration with the Japanese government, with Hokkaido being the frontrunner for its next expansion. Historically known for agriculture and tourism, Hokkaido is now positioning itself as a global semiconductor hotspot.

Hokkaido offers a stable and abundant power supply, especially from renewable energy sources. With the semiconductor industry increasingly prioritizing green energy, Hokkaido’s wind and solar resources, coupled with its cool climate, can reduce cooling and energy costs for fabs. Additionally, the presence of top-tier engineering talent from Hokkaido University and other institutions, combined with aggressive government incentives—including tax breaks, land grants, and workforce training—has attracted semiconductor-related investments. Moreover, Hokkaido’s lower land acquisition costs compared to major metropolitan areas like Tokyo and Osaka make it an ideal location for large-scale industrial development. If TSMC establishes a fab in Hokkaido, it will inevitably drive supply chain players—including materials, equipment, testing, and packaging companies—to follow suit.

This strategic move not only highlights Taiwan’s technological prowess but also marks the beginning of Japan’s semiconductor resurgence. As TSMC’s Kumamoto fab construction progresses, economic activity in surrounding areas is accelerating, presenting new investment opportunities for Taiwanese investors. Below are specific investment options and strategies tailored for those considering Japanese investments.

 

Investment Opportunities & Strategies

1. Real Estate Investment in Japan
  • Ideal for: Investors seeking stable rental income and property value appreciation.
  • Recommended Locations:
    • Kumamoto City & Kikuyo Town: Just 10 minutes from TSMC’s Kumamoto plant, where demand for rental properties from foreign engineers and local employees is strong.
    • Tomakomai & Chitose, Hokkaido: Near New Chitose Airport, offering high potential for logistics, residential, and commercial real estate development.
    • Higashi & Atsubetsu, Sapporo: Close to universities and industrial parks, ideal for rental apartments and employee dormitories.
  • Investment Steps:
    • Work with Taiwanese or Japanese real estate agencies for property selection.
    • Hire a Japanese administrative scrivener or judicial scrivener for property transactions and ownership registration.
    • Open a Japanese bank account for property purchases; consider establishing a Japanese corporation for tax benefits.
    • Use a professional property management company for rental management.
 
2. Stock & ETF Investments
  • Ideal for: Investors looking for simplified management with strong growth potential.
  • Investment Methods:
    • Taiwanese Brokerage Firms: Major firms like Yuanta, Cathay, and KGI allow investments in Japan’s stock market via sub-brokerage services.
    • Opening a Japanese Brokerage Account: Requires a residency visa but provides more direct access. Overseas brokers like SBI Securities also offer options.
 
3. Establishing a Japanese Corporation & Business Investment
  • Ideal for: SMEs, professional investors, and those with cross-border business expertise.
  • Hot Investment Areas:
    • Semiconductor-related services: Engineer recruitment, equipment maintenance, wastewater treatment, and supply chain logistics.
    • Infrastructure: Employee housing, medical clinics, commercial facilities, and restaurants.
    • Education & Training: Engineering training schools and language institutes.
  • Investment Steps:
    1. Establish a Kabushiki Kaisha (KK) or Godo Kaisha (GK) in Japan.
    2. Minimum capital of ¥5 million for an easier application for a business management visa.
    3. Rent an office (co-working spaces acceptable) and open a corporate bank account.
    4. Apply for relevant business licenses (e.g., labor dispatching, logistics, education).
    5. Leverage local government subsidies—Kumamoto and Hokkaido offer 2-3 years of corporate tax reductions and up to 20% in equipment investment subsidies.
 
 

Tax Planning Strategies

1. Real Estate Taxes in Japan
  • Fixed Asset & City Planning Tax: ~1.7% annually.
  • Rental Income Tax: 20.42% withholding tax on rental income.
  • Capital Gains Tax: 15% if held for 5+ years, 30% if held for less than 5 years.
  • Taiwan Tax Considerations: Income may be subject to Taiwan’s global income tax but could be offset via tax treaties.
     
2. Stock & ETF Taxation
  • Dividend Tax: Japan withholds 15%, which can be credited against Taiwan tax obligations.
  • Capital Gains Tax: 15.315% in Japan.
  • CFC & CRS Rules: Taiwanese tax residents should check compliance with Controlled Foreign Corporation (CFC) and Common Reporting Standard (CRS) regulations.
