Japanese Stocks (個別株)

Individual Japanese company stocks if you want to invest in Japan specifically:

  • Blue chips: Toyota, Sony, SoftBank, Recruit Holdings
  • Minimum purchase is typically 100 shares (varies by company price)

Japanese REITs (J-REIT)

Real estate investment trusts — good for dividend income from Japanese property without buying actual real estate.


Tax on Investments

Inside NISA: Completely tax-free — no reporting needed.

Outside NISA (Tokutei account / 特定口座):

  • Capital gains tax: 20.315% (15% national + 5% local + 0.315%)
  • Most brokerages offer 源泉徴収あり (withholding tax at source) — tax is automatically deducted, no separate filing needed

For US citizens: FATCA compliance complicates things significantly. Some brokerages won’t open accounts for US citizens. Consult a tax specialist.


Investing in Foreign Assets from Japan

You can invest in US stocks, ETFs, and global funds through Japanese brokerages. The process:

  1. Convert JPY to USD within your brokerage
  2. Buy US-listed ETFs (VTI, VOO, QQQ) or stocks
  3. Returns subject to Japanese capital gains tax (and potentially US withholding tax on dividends)

Dollar-Cost Averaging (積立投資)

The most recommended approach for beginners:

  • Set up a monthly automatic investment (積立 tsumitate) into an index fund
  • Even ¥5,000–10,000/month builds meaningful wealth over time
  • No timing decisions — removes emotion from investing
