The regulation of Tachibana by the Financial Services Agency (FSA) ensures that the company operates within Japan's legal framework, which protects traders' funds and promotes fair trading practices. The FSA imposes strict guidelines on financial institutions, ensuring transparency and adherence to industry standards. This regulation adds a layer of security for domestic traders, ensuring that their investments are safeguarded. However, as Tachibana is primarily focused on the Japanese market, international traders may have limited access to global regulations and protections.
