The Financial Services Agency (FSA) of Japan has officially expressed concern regarding the business practices of crypto exchanges that guide customers to high-spread "sales offices" (OTC-style) instead of transparent order books. The regulator raised this issue in a report to the Minister for Financial Services, describing the model as a potential "trap" for uninformed investors. The FSA's critique highlights the structural issue where users pay significantly higher costs due to wide spreads, a practice common among Japanese exchanges operating "Hanbaijo" (Sales Office) services. While these interfaces are user-friendly for beginners, the hidden costs compared to exchange order books are substantial. Previously, traders in the Japanese community had been discussing reports that the FSA was preparing to address this issue. The confirmation of the FSA's report signals potential future regulatory pressure on Japanese exchange business models to improve fee transparency and protect retail investors. [Update 1] The FSA has officially flagged these concerns in a report to the Minister for Financial Services, moving beyond community rumors to formal regulatory scrutiny.
