If You've Been Scammed: What to Do After, and Japan's Help Lines
Bottom line: stop the bleeding first, then record and report
"My wallet was emptied." "I sent funds to a fake investment." The moment you notice, the order of actions is fixed: 1) stop further loss → 2) preserve evidence → 3) report to legitimate channels. Sadly, a transfer settled on-chain generally can't be reversed — but you can prevent further loss right now.
Key points
- Top priority: "nothing more gets taken" (revoke approvals, move funds)
- Settled transfers usually can't be recovered — but escalation can be stopped
- Preserve records and report to police, the consumer hotline, and the FSA
- Anyone offering to "recover" your funds is a second scam — never pay or engage
1. Stop further loss (minutes matter)
- Suspect a compromised wallet: immediately revoke all token approvals and move remaining assets to a fresh wallet. If the seed phrase may be exposed, never use that wallet again
- Exchange account breached: change the password, reset two-factor auth, and ask the exchange's support to freeze it
- Stop engaging the scammer: send nothing more, and cut contact
2. Preserve evidence
- The transaction hash, destination address, time and amount
- Screenshots of the conversation (their contact, the site URL, any ads)
- Transfer receipts and exchange history
3. Contact Japan's help lines
| Channel | Contact | Purpose |
|---|---|---|
| Police consultation line | #9110 | Reporting fraud/crime |
| Consumer hotline | 188 (no area code) | Connects to your local consumer centre |
| FSA Financial Services User Consultation | 0570-016811 | Financial-service trouble |
| JVCEA (crypto industry association) | help desk on the official site | Crypto-trading issues |
For urgent or clear crimes, consider a formal report
For high-urgency situations or a clear crime, also consider filing a formal police report. The National Police Agency also provides a cybercrime consultation channel.
4. Never believe "we can recover it" (the second scam)
Beware recovery scams
People and "services" target victims, claiming they can recover your funds for a fee. This is almost always a second scam. Never pay anything to a "recovery service" that demands an up-front fee, DMs you, or advertises on social media. For legitimate help, use the official channels above.
Prevention (for next time)
- Keep large amounts on a hardware wallet, separate from daily use
- Learn the tactics in the scam checklist
- Use two-factor auth and good password hygiene
FAQ
Q. Will the crypto I sent come back? A. A transfer settled on-chain generally cannot be reversed. That's why the realistic steps are "stop further loss" and "report to official channels."
Q. Can the exchange freeze it if I ask? A. Only if the funds landed at an exchange's address and the exchange could act fast. No guarantees — but contacting them quickly is worth it.
