Is forex trading legal in Japan?

Yes. Japan has one of the largest retail FX markets in the world, regulated by the Financial Services Agency (FSA) with strict leverage and client money rules.

Checked 12 Nov 2026Not legal advice

Short answer: forex trading is legal in Japan through brokers registered with the FSA as Type I Financial Instruments Business Operators. Retail leverage is capped at 25:1, and client money must be held in trust. The FSA warns Japanese residents about overseas firms soliciting them without registration.

Overseas brokers

Many offshore brokers market high leverage to Japanese traders. If a firm is not registered with the FSA, Japanese investor protections, including trust-held client money and access to Japanese dispute resolution, do not apply. The FSA publishes warnings naming unregistered firms that solicit Japanese residents.

Watch out: a Japanese-language website does not mean a broker is registered in Japan. Check the FSA's list of registered financial instruments business operators.

Brokers we review

Among the brokers we review, OANDA and IG both operate Japanese companies. Confirm the company name and registration on the FSA list before you open an account, and note that terms at a Japanese company can differ from those in our reviews.

How to check a broker

  1. Find the exact company name in the account agreement.
  2. Search it on the FSA's list of registered Financial Instruments Business Operators.
  3. Search the FSA's warnings about unregistered firms.
