The fake token was only the surface. Behind it was a Chinese network suspected of moving fentanyl precursors, operating through a Nagoya front company, and using Japan’s credibility to make fraud look legitimate.
- Hubei Amarvel Biotech utilizes Nagoya front company Firsky to coordinate fentanyl precursor trafficking and multi-million yen cryptocurrency fraud operations.
- Fraudsters exploit the zksync.jp domain to steal hundreds of millions of yen before the group's Japanese logistics hub liquidated in 2024.
- Criminal syndicates weaponize Japanese corporate credibility to bypass international financial scrutiny and facilitate illicit cross-border shipments of chemical precursors.
The case links Hubei Amarvel Biotech, a Wuhan-based chemical company, to U.S. convictions over fentanyl precursor imports and money laundering. Prosecutors said the company shipped large quantities of precursor chemicals to the United States and used cryptocurrency in parts of the operation.
The Amarvel case showed a network built to move goods, money and information across borders. Nikkei’s reporting suggests the same structure also supported a separate crypto fraud scheme.
The Japan Link
Nikkei reported that the group used Firsky, a Nagoya-based company, as a base for logistics and fund management, and possibly for fraud. A Chinese national described as the “boss in Japan” was also linked to the operation before Firsky was liquidated in 2024.
Japan appears to have mattered because it offered credibility. A Japanese company, a Japanese address and a .jp domain can all make a fraud operation seem more legitimate to outsiders.

The Fake Token
The fraudulent token, zksync.jp, borrowed from the naming logic of legitimate crypto projects while having no connection to the real zkSync network. The use of a familiar-sounding name and a Japanese domain gave the token an added layer of apparent legitimacy.
According to the reporting, victims in Japan and elsewhere were persuaded to send funds, with losses estimated in the hundreds of millions of yen. The scale matters, but the method matters more: the token relied on borrowed trust rather than technical sophistication.
That is what makes the case notable. It shows how a fraud can be built from recognizable signals rather than complex code.
A Broader Pattern
The story points to a network that appears able to move between physical shipments and digital fraud while relying on the same methods of concealment. It also reflects a wider pattern in which Chinese networks use jurisdictions, shell companies and local-facing branding to build trust.
That makes the Japan link more than a detail. It shows how credibility itself can become part of the infrastructure of a scheme.
The Grey Terminal Note
The fake token was not the core story. The real story is a network that used a Nagoya front company and Japan’s credibility to make its operations look legitimate. It moved between chemical shipments, fund management and crypto fraud using the same basic setup: shell companies, local cover and borrowed trust.
