Japan’s Financial Services Agency issued a formal warning to Binance on March 23, 2018, saying the cryptocurrency exchange was conducting virtual-currency exchange business with Japanese residents over the internet without registration.
The one-page notice identified Binance, named Changpeng Zhao as its representative and listed Hong Kong as its location, while cautioning that those company details came from internet information and might not be current. The central fact was narrower and firmer: the regulator said Binance had served people resident in Japan and had been warned under the FSA’s supervisory guidelines.
That made the action a test of whether a national licensing regime could reach a borderless trading platform without a conventional domestic storefront. It was a warning, not a finding that customer assets had been lost, not a criminal charge and not an order announcing a fixed shutdown deadline.
Japan applied its registration perimeter
Japan had introduced registration for virtual-currency exchange service providers on April 1, 2017. The FSA’s English guidance for foreign operators explained that an unregistered foreign provider was barred from soliciting Japanese residents for covered activities, including trading virtual currency or exchanging one virtual currency for another. The guidance also described the corporate presence and local-representative requirements applicable to foreign providers seeking to operate in Japan.
The March 23 notice mattered because Binance’s service was delivered through the internet and offered crypto-to-crypto markets. The FSA nevertheless treated business with Japanese residents as falling inside the regulated perimeter. In institutional terms, online access did not erase the jurisdictional question; customer location and solicitation still mattered.
Reuters reported on March 23 that an FSA official said the agency had set no particular deadline for Binance to stop operating. Reuters also attributed to the regulator concerns that Japanese residents could open accounts without identity confirmation. Zhao said publicly that Binance’s lawyers had contacted the FSA and that the company would seek a solution. Those details are contemporaneous reporting and company statements, not language contained in the one-page warning itself.
A wider supervisory campaign
The action arrived during intensified Japanese scrutiny after the January 2018 Coincheck theft. By March 23, the FSA had already taken administrative action against seven registered or registration-pending exchanges on March 8 and had warned Blockchain Laboratory on February 13 over unregistered activity. The Binance notice therefore fit an expanding enforcement pattern rather than standing as an isolated objection to one overseas venue.
For exchanges, the signal was operational: rapid international growth could create regulatory exposure wherever users were accepted. For customers, the warning distinguished access to a website from authorization by the local financial supervisor. Neither point established that Binance trades were invalid or that the regulator had guaranteed the safety of registered venues.
Binance looked toward Malta
Also on March 23, Bloomberg reported that Zhao planned to open an office in Malta and pursue a fiat-to-crypto exchange there, while providing no launch timetable. The same-day juxtaposition illustrated the industry’s jurisdictional mobility: a platform could respond to pressure in one market by seeking banking and regulatory relationships in another.
The Malta plan was prospective on March 23. It should not be read as proof that a Maltese exchange, banking partnership or license was already operating. Likewise, no venue-specific price or volume dataset used in this reconstruction isolates a market response to the Japanese warning, so no bitcoin, BNB or broader-market move is attributed to it.
What can be established for March 23 is the regulatory event itself: Japan publicly applied its exchange-registration framework to Binance’s online business with residents, and Binance said it was engaging with the regulator while exploring a new European base.
