Yes, Okasan Securities is regulated under the Japan Financial Services Agency (FSA) with the license number 関東財務局長(金商)第53号. This means that Okasan Securities operates under stringent regulations set by the FSA, ensuring a high level of investor protection and transparency. The FSA is known for its rigorous supervision of financial institutions, and this regulation provides a safety net for traders by ensuring that Okasan Securities follows the rules for protecting investor funds. However, it is important to note that some of Okasan Securities' online entities, such as 岡三オンライン証券株式会社, have faced some discrepancies regarding their regulatory status. This issue has caused confusion for traders who may not be fully aware of which entity they are dealing with. Although the main entity, Okasan Securities Co., Ltd., is well-regulated, online branches may not have the same level of clarity. Therefore, it's important for traders to verify the entity they are engaging with to ensure they are operating within the framework of regulatory oversight. Despite this, Okasan Securities’ long-standing reputation and regulation under the FSA still provide significant trust and security to its users. It's advisable for investors to perform due diligence, ensuring they are interacting with the correct entity within Okasan Securities' network. By doing so, they can avoid potential risks tied to unregulated branches.
