You can invest in Japanese-listed shares through a securities broker, but the right account depends first on whether you qualify as a Japan resident for NISA purposes. NISA can shelter qualifying investment returns from Japanese tax, while taxable accounts have different loss-offset rules. Before choosing, check residency eligibility, how dividends are paid, the broker’s fees, and the 100-share trading unit used for domestic shares.
Choose an account based on residency and tax treatment
For investors who meet Japan’s eligibility rules, the main choice is between a NISA account and a taxable account. NISA is a tax wrapper for eligible investments, not a separate investment, and it does not protect you from losses. The Financial Services Agency (FSA) says Japan residents aged 18 or older may open one NISA account per person and may change financial institution by year. See the FSA’s NISA guidance.
| Account consideration | NISA | Taxable account |
|---|---|---|
| Eligibility | For eligible Japan residents aged 18 or older; one account per person under current FSA guidance. | Depends on the broker and account setup. |
| Tax on qualifying listed-share dividends and sale gains | Exempt when the investment and handling meet NISA rules. | Tax treatment depends on income type and the investor’s circumstances. For listed-share dividends, the separate-taxation option has a 20.315% rate under the NTA’s 2026 guidance; eligible dividends may instead be reported under comprehensive taxation. |
| Using investment losses | NISA losses cannot offset taxable-account listed-share gains or dividends and cannot be carried forward. | Listed-share losses may be offset subject to applicable rules and filing requirements. |
The FSA and National Tax Agency (NTA) set out the NISA exemption and loss rules, as well as the rules for listed-share loss offsets. The NTA’s dividend guidance explains the 20.315% separate-taxation rate: 15.315% national income and reconstruction special income tax plus 5% local tax. That rate applies when the separate-taxation option is selected; it is not necessarily every investor’s final treatment.
How the current NISA limits work
The NISA framework introduced in January 2024 is permanent and has an indefinite tax-exempt holding period. Its two annual investment quotas can be used together:
#1 Best Overall
| Quota or limit | Amount |
|---|---|
| Annual tsumitate quota | ¥1.2 million |
| Annual growth quota | ¥2.4 million |
| Combined annual ceiling | ¥3.6 million |
| Lifetime non-taxable holding limit | ¥18 million |
| Maximum within the growth quota | ¥12 million |
These limits are stated in current FSA guidance and the NTA’s NISA guidance. When you sell an investment, its acquisition-cost amount becomes available for reuse from the following year. Selling does not immediately restore that year’s annual quota.
Make sure NISA dividends use the qualifying payment method
Qualifying listed-share dividends held in NISA are tax-exempt only when they are routed through the financial institution holding the NISA account using the stock-proportional allocation method. If the issuing company pays the dividend directly to you, the NTA says it is taxable instead. Confirm the dividend-receipt setting with your broker and check that it is set to the required method. The NTA describes this condition in its NISA rules.
Understand the share unit and trading hours
Domestic shares listed on the Tokyo Stock Exchange (TSE) trade in standard units of 100 shares. For a standard-lot purchase, multiply the share price by 100, then account for the broker’s applicable charges. The Japan Exchange Group (JPX) trading-unit guidance describes the 100-share unit.

JPX lists TSE daytime sessions as 9:00–11:30 and 12:30–15:30 Japan time. The exchange is closed on weekends and national holidays, as well as January 1–3 and December 31. Check the JPX trading-hours page when planning an order.

Compare broker fees instead of assuming a standard rate
There is no single commission figure that applies to all Japanese stock trades: securities companies set their own charges. Compare the specific broker’s current fee schedule for your account type, residence, order size, and trading service. JPX’s guidance on foreign-stock trading says commissions are provider-set and notes that a foreign-securities account may have an additional management fee. That does not mean every domestic Japanese-share account has such a fee.
- Commission by order value or trading plan
- Account maintenance or custody charges, if any
- Any additional charge for foreign-market services, if relevant
- Currency-conversion costs if funding or trading in a non-yen currency
- Pricing and eligibility for any small-lot service, if you do not want to buy a standard 100-share unit
For each provider, confirm that it accepts your residence and supports the shares, account type, and order size you intend to use. Fees and product access can differ by provider and may change.

Do not assume Japan-resident NISA eligibility or resident tax treatment applies to you if you live outside Japan. The FSA’s International Financial Center FAQ says a nonresident’s Japanese tax treatment can depend on whether they have a permanent establishment in Japan and on any applicable tax treaty. Its general summary assumes a nonresident without a Japanese permanent establishment: listed-share dividends may be subject to withholding, while many share-sale gains are treated as non-taxable in Japan under that assumption. Your country of residence may tax the income, and individual circumstances can change the result. Check the broker’s residence requirements and obtain tax advice for your situation.
