    • Requesting money transfers under the guise of account opening procedures
    • Soliciting personal information (name, address, account numbers, etc.) via social media
    • Instructing customers to make deposits to unknown bank accounts
    • Interactive Brokers Securities Japan Inc. will never solicit account openings, money transfers, or personal information through LINE or social media.

How to Protect Yourself

Phishing scams change rapidly. You can protect yourself by following these simple rules:

    When You Receive Emails or Messages

  • First and always, verify the sender's email address and domain name. If the message is sent from a domain other than our official domain, it may be fraudulent.
  • Do not click on links in emails without careful consideration. When in doubt, do not click on any links. Instead, access your account directly by using the login button on our official website: www.interactivebrokers.co.jp.

    When Contacted via Social Media or Messaging Apps

  • If you are contacted via social media or messaging apps by someone claiming to represent our firm, ignore them, do not respond, and do not click any URLs. Treat these contacts as highly suspicious.
  • If you receive suspicious messages or solicitations, always verify by contacting us through the phone number or inquiry form listed on our official website.

    When Asked to Transfer Money

  • Never, under any circumstance, transfer money to unknown bank accounts if requested. Doing so places your assets in immediate danger.
  • Our legitimate account opening procedures never require transfers to third-party accounts.

Our Official Communication Channels

Interactive Brokers Securities Japan Inc. conducts official account opening procedures, provides information, and communicates with customers through the following methods:

  • Official Website: www.interactivebrokers.co.jp
  • Legitimate Email Communications (sent from our official domain)
  • Phone Calls from Numbers Listed on Our Official Website

If you are ever asked to open an account or provide personal information through unofficial channels, it is almost certainly a fraudulent scheme. Treat such requests as urgent threats to your security.

What to Do If You Receive Suspicious Communications

    If you receive suspicious communications or messages, please act immediately:

  1. Contact Our Firm: Immediately contact us through the inquiry form on our official website.
  2. Consult the Police: We recommend consulting with the Police Consultation Hotline (#9110).
  3. Share Information: To help prevent similar damage to others, please inform us of any suspicious emails or messages you receive.

If you have concerns, always verify through our official channels before acting.
