Why invest in Japanese stocks as a foreign resident
Japan is home to one of the largest stock markets in the world. The Tokyo Stock Exchange (TSE) and other domestic exchanges handle huge daily trading volumes and list many global brands in technology, automotive, finance and consumer goods.
For long-term residents, investing can be a smart complement to cash savings and the Japanese pension system. At the same time, the Japanese government is actively encouraging individuals to move from cash to investments through tax-advantaged accounts like the new NISA, introduced in 2024 with permanent tax-free status and higher limits.
If you plan to stay in Japan for several years, investing in local stocks and funds can help you:
- Grow yen savings for future goals
- Learn how the Japanese financial system works
- Build assets you may later move when taking money out of Japan()
Of course, investing always involves risk. This article is information only, not personal investment or tax advice.
Basics of the Japanese stock market
Main exchanges and indices
Most stock trading in Japan happens on markets operated by the Japan Exchange Group (JPX), mainly the Tokyo Stock Exchange.
Key stock indices you will see in your brokerage app include:
- Nikkei 225 โ 225 large companies, price-weighted
- TOPIX โ broader index covering all โPrime Marketโ companies, market-cap weighted
- Various sector and themed indices
When you buy a Japanese stock or ETF through a local broker, you are usually trading on these exchanges in Japanese yen.
Trading units and minimum order sizes
In Japan, the standard trading unit is 100 shares for most listed domestic stocks.
That means:
- You normally place orders in multiples of 100 shares (100, 200, 300, and so on).
- For a stock priced at ยฅ1,500, the minimum typical order would be 100 shares = ยฅ150,000 (plus fees).
Some ETFs, REITs and a small number of stocks use other units, and many companies allow special procedures to deal with โodd lotsโ below 100 shares, but as a beginner it helps to think in 100-share blocks.
Because of this, many new investors start with low-cost index funds and ETFs through NISA instead of individual high-priced shares. We will come back to this.
Can foreigners invest in Japanese stocks?
Yes. In general, foreign residents with a valid address in Japan can open brokerage accounts and invest in Japanese stocks, ETFs and mutual funds.
Guides for foreign residents explain that opening a securities account usually requires:
- A valid residence card (ๅจ็ใซใผใ / Zairyลซ card)
- Passport
- My Number (Individual Number) card or notification
- A Japanese address and contact details
International brokers that serve residents in Japan, such as Interactive Brokers Securities Japan, list similar requirements for individual applicants trading Japanese and foreign products: proof of identity, address, and tax ID details.
Important points:
- You generally must be a resident, not a tourist, to open a Japanese domestic brokerage account.
- Some brokers have extra rules or restrictions for certain visa types, so always check their English or Japanese FAQ pages.
- If you later move overseas, your broker may place limits on your account, especially for NISA (you must close it once you no longer have Japanese residency).

Types of investment accounts in Japan
When you open a brokerage account, you will often be asked which account type you want. The main ones are:
- A standard taxable brokerage account
- A NISA account (tax-free investing)
- An iDeCo account (tax-advantaged pension investing)
Here is a simple comparison.
Investment account types in Japan
Details are simplified. Always check latest rules and your own eligibility.
| Account type | Main purpose | Tax on gains & dividends | Annual contribution limit | Who can use it? | Good to know |
|---|---|---|---|---|---|
| Regular taxable brokerage | General investing in stocks, ETFs, funds | Normally taxed at flat 20.315% for listed shares (national + local taxes) | No formal limit | Most residents who pass broker checks | Simple and flexible; can buy almost any product your broker offers. |
| New NISA (from 2024) | Tax-free investing for individuals | Gains and dividends tax-free within NISA limits | Up to ยฅ3.6 million per year, with lifetime tax-free holding limit of ยฅ18 million | Residents with Japanese address and My Number; foreigners are allowed if they meet conditions | No time limit on tax-free holding; must close the account when you permanently leave Japan. |
| iDeCo (individual DC pension) | Long-term retirement savings | Contributions are income-tax deductible; investment growth tax-deferred; withdrawals taxed later | Max ยฅ14,000โยฅ68,000 per month depending on employment status | Certain residents who pay into Japanese pension system and meet age rules | Money is locked until at least age 60; more complex but powerful for long-term residents. |
The new NISA system made tax-free investing easier by removing the old time limits and increasing both annual and lifetime investment limits. English guides aimed at foreign residents confirm that foreigners with a valid residence card and address can use NISA, but need to close it when they leave Japan.
For many people, a practical path is:
- Open a standard brokerage account.
- Add a NISA account with the same broker to build long-term tax-free investments.
- Consider iDeCo only if you expect to stay in Japan long-term and want extra pension savings. See Pension basics for more detail.
Choosing a brokerage in Japan
Domestic vs international brokers
As a resident in Japan, you can usually choose between:
- Japanese domestic brokers โ focus on TSE stocks, Japanese funds, NISA, iDeCo
- International brokers serving Japan โ focus on global markets; Japanese stocks may be available but often as part of a wider offering
Recent broker comparison sites list popular choices for residents in Japan, including:
- Domestic online brokers like SBI Securities, Rakuten Securities, Monex, Matsui, and au Kabucom (often mentioned in Japanese-language guides as foreigner-friendly).
- International platforms like Interactive Brokers, IG, moomoo and others, which are registered with regulators in several countries and accept Japan-based clients.
Domestic brokers are best if you:
- Want NISA or iDeCo
- Mainly invest in Japanese stocks, ETFs and mutual funds
- Prefer Japanese-language customer support (some have limited English)
International brokers are better if you:
- Want to invest in global stocks and ETFs in many markets
- Prefer English interfaces and support
- Are comfortable handling tax reporting yourself
Many foreign residents end up using both: a domestic broker for NISA and yen-based investments, plus an international broker for global diversification.
What to compare when you pick a broker
When comparing brokerage options, check:
- Language support โ Does the website or app have English? Is support available in English?
- Fees โ Trading commissions, account fees, currency conversion charges.
- Products โ Japanese stocks, ETFs, mutual funds, global markets, margin trading, options, etc.
- Account types โ Does the broker offer NISA and iDeCo, or only regular accounts?
- Minimums โ Any minimum account size or order size beyond the standard 100-share lot?
- Funding methods โ Can you use domestic bank transfer, convenience store payment, or card?
- Non-resident rules โ What happens to your account if you leave Japan later?

Step-by-step: opening a Japanese brokerage account
Different companies have different screens, but the basic process is similar. Below is a general flow for opening an account with a domestic online securities company.
Step 1 โ Prepare your basic setup
Before you apply, make sure you have:
- A Japanese bank account in your name (for funding and withdrawals). See Opening a bank account in Japan if you do not have one yet.
- Your residence card and passport.
- Your My Number card or notification.
- A Japanese address and phone number.
Guides for foreigners note that these documents are standard for most brokers, whether you apply online or by post.
Step 2 โ Choose your brokerage and account type
On the brokerโs website:
- Select that you are opening an account as an individual resident in Japan.
- Choose the account types you want:
- Regular taxable account
- NISA account (you can also add it later)
- iDeCo account (often a separate application)
Step 3 โ Fill in the online application
You will be asked to enter:
- Name, date of birth, and nationality
- Japanese address and phone number
- Employment and income information
- My Number
- Investment experience and risk tolerance
Regulators require brokers to collect this information to check suitability and comply with โknow your customerโ (KYC) rules.
Some brokers now allow you to complete everything in a smartphone app, with English hints or partial translations.
Step 4 โ Upload your documents
Usually you will upload photos or scans of:
- Residence card (front and back)
- My Number card or notice + another ID if needed
- Sometimes a proof of address (for example, health insurance card or utility bill)
Guides on foreign residents opening accounts confirm that many major online brokers accept fully digital applications as long as the documents are clear.
Step 5 โ Wait for review and receive login details
After you submit, the broker will review your application. If everything is fine, you will receive:
- Approval notice by email
- Login details by mail or in the app
- Sometimes a short welcome booklet explaining trading and risks
This may take a few days. During this time, you can read more about Investing basics in Japan or Cost of living in Japan to plan how much you want to invest every month.
Step 6 โ Link your bank account and deposit funds
Once the account is open, you link your Japanese bank account. Common methods:
- Furikomi (domestic bank transfer) from your bank to your brokerage cash account
- Real-time online deposit if your bank is partnered with the broker
- In rare cases, convenience store deposit or ATM transfer
Most brokers show your cash balance in yen. Now you are ready to buy your first Japanese stock or fund.
Opening an account with an international broker
If you also want access to global markets (US, Europe, etc.), you might open an account with an international firm that accepts residents in Japan, such as Interactive Brokers or others listed in 2025 broker comparisons.
The basic process is similar:
- Fill in an online form with your personal details and Japanese address.
- Provide identity and address documents (passport, residence card, possibly My Number).
- Answer questions about your investment experience and objectives.
- Fund the account via international or local bank transfer.
These platforms are powerful but can be complex, so they are usually better if you already have some investing experience. If you are a complete beginner, it is often easier to start with a domestic broker and NISA first.
How stock investing is taxed in Japan
In a regular taxable brokerage account, profits from selling listed shares and many financial instruments are usually taxed at a flat 20.315%, which combines national and local taxes.
Key points:
- This rate applies to capital gains (profits when you sell for more than you paid).
- Dividends from Japanese stocks are generally taxed at a similar combined rate if not sheltered by NISA.
- You can often offset losses against gains within the same year, and in some cases carry forward losses up to three years if you file correctly.
Inside a NISA account:
- Selected investments can grow tax-free on dividends and capital gains, within your NISA limits.
- The new NISA (from 2024) allows indefinite tax-free holding, as long as you stay eligible.
Inside iDeCo:
- Contributions are income-tax deductible, but the money is locked up until at least age 60 and taxed when you withdraw.
Tax rules can be complex, especially if you also have income or investments outside Japan. For deeper reading, see Tax basics for foreign residents in Japan and Double taxation in Japan, and consider talking to a qualified tax adviser.
Placing your first trade in Japanese stocks
Once your account is funded, the basic flow to buy a Japanese stock looks like this:
- Search for the stock or ETF
- You can search by company name (for example, Toyota) or code (ticker, such as 7203).
- Choose order type
- Market order โ buy immediately at current market price.
- Limit order โ you set the maximum price you are willing to pay.
- Choose quantity
- Remember that most Japanese stocks trade in units of 100 shares, so check the required quantity.
- Check fees and confirm
- The order screen will show estimated commission and total cost.
- Always double-check the number of shares and order type before pressing โsubmitโ.
- Review your holdings
- After execution, your shares will appear in your portfolio list.
- You can track prices, dividends, and unrealized gains/losses in the app.
If you are using NISA, make sure that you are placing your order inside your NISA account, not the regular account, when you want tax-free treatment. Guides for foreigners emphasize that this is a common beginner mistake.
Practical tips for new stock investors in Japan
- Start with a simple plan
- Many foreign residents begin with monthly investments into low-cost index funds or ETFs via NISA, rather than trying to pick individual stocks.
- Invest money you can leave alone
- Because the stock market moves up and down, money you may need soon (like next monthโs rent) should stay in cash. See Budgeting and saving tips in Japan for ideas.
- Automate where possible
- Some brokers let you set automatic monthly purchases of mutual funds or ETFs. This can help you stick to a plan without over-thinking every move.
- Watch costs
- Compare brokerage commission plans and fund fees (expense ratios). Over many years, even a 0.2โ0.3% difference can matter. Comparison sites that rank brokers in Japan highlight fee differences clearly.
- Think in yen and in life goals
- If you plan to stay in Japan long term, yen investments make sense for local goals (housing, education, retirement). If you will eventually return home, you may also want global diversification through an international broker.
- Avoid leverage and complex products at first
- Margin trading, options, and leveraged ETFs can magnify both gains and losses. Most beginners are better off avoiding them until they fully understand the risks.
- Keep good records
- Save your trade confirmations and annual tax reports from your broker. These are useful for tax filing and for future steps like Taking money out of Japan when you leave.
- Stay within your comfort zone
- If Japanese-language screens feel overwhelming, look for brokers with better English support or simple interfaces, and take your time.
Common challenges for foreigners (and how to handle them)
Foreign residents often mention a few recurring pain points when opening brokerage accounts in Japan:
- Language barrier โ Many brokers are mainly Japanese-language. Some English-language blogs recommend starting with firms that provide English instructions or using browser translation tools while you learn the key terms.
- Understanding My Number rules โ It can feel intrusive to give your Individual Number, but Japanese law requires it for most financial accounts, including securities, for tax reporting.
- NISA confusion โ The switch to the new NISA in 2024 changed limits and structures. Foreign-friendly guides show that your old NISA typically converted automatically, but the screen layout may look different.
- Moving away from Japan โ When you leave, you must close your NISA and update or close domestic brokerage accounts. Some investors move holdings to a foreign brokerage or simply sell and repatriate cash; see Taking money out of Japan when you leave and Pension refund guide for Japan.
Knowing these issues in advance makes the process much smoother.
Final thoughts
Opening a brokerage account in Japan is a big step, but it is very achievable, even as a foreign resident. Once you have:
- A Japanese bank account and My Number
- A domestic broker (for NISA and yen investments)
- Optional access to an international broker for global markets
you have all the tools you need to start investing in Japanese stocks in a calm, long-term way.
