"Fall seven times, rise eight."
EthGuardians is a blockchain intelligence firm registered in Hong Kong SAR. We help victims of crypto fraud in Japan trace stolen assets and pursue recovery through legal channels. 96% historical recovery rate across closed cases. No win, no fee.
Japan treats cryptocurrency as a legal category of property. Exchanges must register with the Financial Services Agency (FSA), and the FSA publishes a warning list of unregistered offshore platforms. If a platform solicited you and is not on the FSA register, that fact alone matters for your case.
The first official step is the police cybercrime consultation line, #9110, or the cybercrime unit of your nearest police station. JC3, the Japan Cybercrime Control Center, coordinates intelligence across prefectures. File the report and keep the reference number. It establishes your status as a victim and starts the official record. Bring transaction hashes, receiving wallet addresses, the platform URL, and every chat log.
The dominant scam pattern in Japan today is the social media investment group. An advertisement impersonating a celebrity or a famous investor leads to a LINE group, where a "teacher" and "assistants" guide members to deposit on a fake exchange. Balances on screen are fabricated. When you try to withdraw, they demand taxes or fees first. That demand is the signature of the fraud. Romance scams through matching apps follow a similar script at a slower pace.
Japan has seen this world before. The Mt. Gox and Coincheck incidents are national memory, and they made the Japanese public rightly skeptical of anyone promising easy answers about crypto. We respect that skepticism. We answer it with verifiable facts: a written assessment before you commit to anything, a company registration in Hong Kong SAR under AI Data Intelligence, and a Swiss legal partnership through SarahLegal.io.
We handle cases from Tokyo, Osaka, Yokohama, Nagoya, and Fukuoka, and the entire process runs online, so your location never limits your options.
The national police phone line for cybercrime consultation. Your nearest police station can also take the report.
The regulator that registers and supervises crypto exchanges. It publishes warnings about unregistered operators.
The Japan Cybercrime Control Center, which coordinates cybercrime intelligence across agencies.
Tokyo, Osaka, and Yokohama most often, but the process is fully online and open to clients anywhere in Japan.
We combine blockchain forensics, Ethereum smart contract technology, and Swiss legal expertise to trace, freeze, and recover digital assets lost to any type of fraud.
A structured four-step process combining advanced blockchain forensics with formal legal action.
We never promise outcomes. We can, however, be honest about patterns. The labels below reflect general tendencies; your written assessment decides what applies to your case.
Victims of one scam are targeted again by fake recovery services. We never ask for seed phrases, private keys, two-factor codes, remote desktop access, or any upfront payment. Anyone who asks for these in our name is an impersonator.
The following testimonials represent verified client experiences. Names are anonymised to protect client privacy.
Osaka, Japan • March 2025
"I sent 7.2 million yen to a fake exchange. The police took my report but nothing moved. EthGuardians traced the flow of funds within three weeks, and 6.4 million yen came back. Their careful written updates earned my trust."
Yokohama, Japan • November 2025
"Someone I met on a matching app persuaded me to invest, and I lost 4.8 million yen. Shame kept me silent for months. My case manager never judged me once. We recovered 3.9 million yen."
You pay nothing when you engage us. Our fee, agreed in writing before work begins, comes out of recovered funds after they reach your wallet. If we do not recover anything, you owe nothing.
Never. We do not ask for seed phrases, private keys, two-factor codes, remote desktop access, or any upfront payment. Anyone who asks for these in our name is an impersonator.
Call the police cybercrime consultation line #9110 or visit the cybercrime unit of your nearest police station. Keep transaction hashes, receiving wallet addresses, the platform URL, and all chat records. Checking the platform against the FSA warning list also helps.
It depends on the case. You receive a written assessment within 24 hours. Tracing takes weeks; cases that involve court action can take months. We give you an honest outlook in writing before you commit to anything.
Four things: no upfront fees, no requests for seed phrases, a written assessment before you commit, and a verifiable company registration. EthGuardians is registered in Hong Kong SAR under AI Data Intelligence.
The blockchain does not forget. Delay makes tracing harder, but the record of every transaction is still public. A free case review tells you where you stand.
