Being regulated by the Financial Services Agency (FSA) means that Imamura Securities is subject to strict financial oversight and has to adhere to rigorous reporting and operational standards. This regulation helps ensure that the broker operates transparently, keeping client funds safe and abiding by the law. For traders, this means a certain level of security when using Imamura, as the FSA ensures fair treatment, though the broker’s lack of language support for non-Japanese traders could be a barrier.
