Summary

Japan’s Financial Services Agency warned KuCoin, NeonFX, theoption, and GTCFX for allegedly soliciting over-the-counter derivatives trades online without registration. The firms received notices in March, and KuCoin was specifically listed as serving Japanese residents. The action follows similar warnings issued in November 2024 and comes after the regulator sought app download suspensions in February 2025, indicating continued enforcement against unregistered crypto and financial operators targeting users in Japan.

Terms & Concepts
  • over-the-counter derivatives: Financial contracts traded directly between parties rather than on a public exchange, often subject to regulatory restrictions when offered to retail users.
  • Unregistered operator: A financial or crypto-related business offering services without obtaining the required local regulatory approval or license.
  • Financial Services Agency: Japan’s main financial regulator, responsible for oversight of financial institutions and enforcement actions such as warnings and registration requirements.
