While Naito Securities is regulated by the FSA, it does have a couple of drawbacks. The most significant disadvantage is the complicated fee structure, which makes it difficult to estimate the full cost of trading. The consignment trading fees, in particular, can vary greatly based on the contract price, ranging from JPY 2,750 to JPY 33,550. Additionally, the broker does not offer a demo account, which could deter beginners from using the platform. For naito account holders, the absence of a demo account is a notable limitation, especially for new traders who need to practice before risking real money.
