Is Binary Options Trading Legal in Japan? (FSA Status)

The Financial Services Agency of Japan states that carrying on binary options trading as a business with investors resident in Japan requires registration as a financial instruments business. The FSA says doing so without registration under the Financial Instruments and Exchange Act is illegal, and that this applies even to firms licensed overseas.

What the Rules Say

The Financial Services Agency (FSA) of Japan published guidance regarding binary options trading on 28 February 2020, updated on 28 June 2024. The FSA states that carrying on binary options trading as a business with investors resident in Japan requires registration as a financial instruments business. Carrying on financial instruments business without registration under the Financial Instruments and Exchange Act is illegal.

The FSA states that even a firm holding a financial instruments licence overseas is prohibited from carrying on financial instruments business with persons resident in Japan without registration in Japan. The FSA warns that if you trade with an unregistered firm, pursuing that firm is extremely difficult even if trouble arises.

The FSA says financial instruments business operators are required, under the Act and related rules, to set rules on binary options and to trade appropriately in line with those rules. The FSA (Local Finance Bureaus) lists entities it has warned for operating without registration.

The FSA describes binary options as a trade in which you choose between two alternatives, based on forecasting the rise or fall of an exchange rate or stock index and similar over a set time or period, such as higher or lower than a certain value or within a certain range; you pay an option fee when buying, and after a set time it is judged whether the rate meets the pre-set condition, receiving a fixed payout if the forecast is correct.

How to Check a Firm

The FSA tells investors to confirm that the counterparty is a firm registered under the Financial Instruments and Exchange Act before trading.

If a firm does not appear on the relevant register, treat that as a reason to stop and check further before sending money.
