Exness Japan: FSA Warning and What It Means for Residents (2026)

Short answer: There is no registered "Exness Japan". On April 21, 2023, Japan's Financial Services Agency (FSA) issued a warning that Exness, operated by Nymstar Limited, is an unregistered business that was soliciting Japanese residents. The FSA warns that dealing with unregistered firms can bring problems such as refused withdrawals, and that Japanese investor-protection rules do not apply.

Risks of using an unregistered foreign broker

• Withdrawal disputes. The FSA says people have reported refused withdrawals when dealing with unregistered firms.
• Limited recourse. The FSA's warnings note that a firm outside Japan's registration system is not covered by the protections that apply to registered brokers, so recovering money in a dispute is harder.
• Legal and tax questions. Profits may be taxed differently from those at a registered Japanese broker. See our Japanese tax guide and consult a tax professional.

How to check a broker's status in Japan

1. Search the broker's name in the FSA's registered financial instruments business list.
2. Check the FSA's list of unregistered businesses that have received warnings.
3. Read the company named in the client agreement, and check its regulator's own register.
