You can invest in Japanese-listed shares through a securities firm, but the right account and costs depend on your residence, tax status and trading needs. For eligible Japan residents, NISA can shelter qualifying dividends and gains from tax; it does not remove investment risk, and losses inside NISA cannot offset taxable gains. Domestic shares generally trade in 100-share units, while broker fees are set by each provider.
Start with residence and account eligibility
The first question is where you are resident for Japanese account and tax purposes—not simply whether you are a Japanese citizen. Japan’s current NISA framework is for residents aged 18 or older. It permits one NISA account per person, with the financial institution changeable by year. Check with a securities firm that accepts your residence and offers access to the Japanese shares you want before opening an account. Japan’s Financial Services Agency (FSA) NISA guidance describes eligibility and account rules.
Nonresidents should not assume they can open or continue using a resident NISA account, or that resident tax treatment applies to them. Japan’s tax treatment may depend on factors such as whether the investor has a permanent establishment in Japan and whether a tax treaty applies. The FSA’s International Financial Center FAQ gives a general summary for nonresidents without a Japanese permanent establishment; the investor’s country of residence may also tax the income. Confirm the applicable rules with the broker and a tax adviser familiar with both jurisdictions.
How Japan’s NISA works
NISA is a tax-advantaged account framework, not a type of investment and not protection against losses. The current framework began in January 2024, is permanent, and has no fixed end date for the tax-exempt holding period. It has two annual investment quotas that can be used together:

- Used Book in Good Condition
| Quota or limit | Amount | What it means |
|---|---|---|
| Tsumitate investment quota | ¥1.2 million per year | Annual limit for eligible investments in this quota. |
| Growth investment quota | ¥2.4 million per year | Annual limit for eligible investments in this quota; it may be used alongside the tsumitate quota. |
| Combined annual ceiling | ¥3.6 million per year | Maximum annual investment across both quotas. |
| Lifetime non-taxable holding limit | ¥18 million | Total limit across NISA, including a maximum of ¥12 million in the growth quota. |
These are the limits stated in current FSA and National Tax Agency (NTA) guidance. When you sell an investment, its acquisition-cost amount becomes available for reuse from the following year; selling does not restore that year’s annual quota immediately. See the FSA NISA overview and the NTA’s NISA tax guidance.
What taxes apply to Japanese stock gains and dividends?
Qualifying returns inside NISA
Listed-share dividends and sale gains on qualifying shares held in NISA are tax-exempt in Japan under the NISA rules. For a listed-share dividend to qualify, it must be paid through the financial institution holding the NISA account using the stock-proportional allocation method. If the issuer pays the dividend directly to you, the NTA says it is taxable instead. Confirm the dividend-receipt method with your broker before investing for income.
NISA’s loss trade-off
A loss in NISA cannot be used to offset gains or dividends in a taxable account, and it cannot be carried forward. For Japanese tax purposes, the NTA treats the NISA loss as if it did not exist. This matters when comparing NISA with a taxable account: the NISA exemption on qualifying profits comes with no tax-loss relief for losses inside the wrapper. The NTA’s NISA guidance sets out these rules; its separate listed-share loss-offset guidance covers taxable-account loss treatment.
Dividends outside NISA
For listed-stock dividends outside NISA, the NTA’s 2026 guidance gives a 20.315% rate when the separate-taxation option is selected: 15.315% national income tax and reconstruction special income tax, plus 5% local tax. Eligible dividends may instead be reported under comprehensive taxation, so 20.315% is not necessarily every investor’s final tax treatment. Your residence, account arrangement and individual tax circumstances can affect the result. See the NTA guidance on listed-share dividends.
How much money do you need to buy Japanese shares?
Domestic shares on the Tokyo Stock Exchange generally trade in units of 100 shares. For a standard lot, estimate the purchase value by multiplying the share price by 100, then add applicable broker charges. For example, if a share is quoted at ¥1,000, a 100-share lot would have a purchase value of ¥100,000 before fees. The actual minimum outlay depends on the share price and whether your broker offers a service for buying fewer than 100 shares. Japan Exchange Group (JPX) trading-unit guidance explains the standard lot rule.
Trading hours and order timing
JPX lists Tokyo Stock Exchange daytime sessions as 9:00–11:30 and 12:30–15:30 Japan time. The exchange is closed on weekends, national holidays, January 1–3 and December 31. If you are outside Japan, convert these sessions to your local time and account for daylight-saving changes where relevant. Check your broker’s order-entry cutoffs and handling of orders placed outside the session. Current hours and holiday information are listed on the JPX domestic trading page.
Japanese stock trading fees: what to check
There is no single standard commission established for every investor: securities firms set their own charges. The applicable cost can vary by provider, order size, account type, residence and service. Before funding an account, compare the provider’s current schedule for the particular account and market access you intend to use. JPX’s securities-company fee guidance confirms that commissions are provider-set; its mention of foreign-securities account management fees does not mean every domestic Japanese-share account carries one.
- Commission per order, including how the rate changes with order value.
- Account maintenance, custody or service charges that apply to your account.
- Any separate pricing for small-lot purchases if you plan to buy fewer than 100 shares.
- Currency-conversion costs if you fund or trade in a currency other than yen.
- Eligibility and account terms for your country or region of residence.
Choosing between NISA and a taxable account
Compare the accounts against your eligibility, intended holdings and tax situation rather than choosing on the tax label alone.

|---|---|---|
| Eligibility | Japan residents aged 18 or older under the FSA’s current guidance; one account per person. | Depends on provider, residence and account setup. |
| Tax on qualifying gains and dividends | Exempt in Japan when NISA requirements are met; listed-share dividends require the stock-proportional allocation method through the NISA financial institution. | Tax treatment depends on income type and the investor’s circumstances. For listed-stock dividends, the NTA’s 2026 separate-taxation rate is 20.315% when that option is selected. |
| Loss treatment | Losses cannot offset taxable-account gains or dividends and cannot be carried forward. | Listed-share losses may be offset subject to rules and filing requirements; the result depends on the investor’s tax position and account setup. |
| Investment and service access | Check that the desired shares and order sizes are supported; NISA eligibility does not guarantee a particular investment is available. | Check the provider’s market access and order-size options. |
| Fees | Provider-set; check charges for the specific account and services. | Provider-set; check charges for the specific account and services. |
Official information on NISA eligibility and limits is available from the FSA; the NTA explains NISA tax treatment and listed-share loss offsets. Taxable-account loss relief is subject to conditions, so do not assume a loss will automatically reduce tax.
Quick Recap
A practical checklist before placing an order
- Confirm residence eligibility. Ask the broker whether it accepts clients resident in your location and which account types are available to you.
- Choose the account based on tax and loss treatment. If you are eligible for NISA, consider the exemption alongside the inability to offset NISA losses.
- Check the investment and lot size. Confirm the security is available and whether you must buy 100 shares or can use a broker’s smaller-lot service.
- Calculate the full cost. Multiply the quoted share price by the order size and add commission and any applicable account, custody or currency-conversion charges.
- Set dividend handling if using NISA. Verify that listed-share dividends will use the stock-proportional allocation method through the NISA financial institution.
- Review current tax guidance. If you are a nonresident, have cross-border income or are unsure which dividend tax option applies, confirm the result with a qualified adviser before trading.
