Yes, Shizuoka Tokai is a safe platform in terms of regulation. It is licensed by the Financial Services Agency (FSA), ensuring that it adheres to Japan's financial laws, which protect investors. However, the safety of trading also depends on personal risk tolerance. Since Shizuoka Tokai does not offer high-risk assets like forex or cryptocurrencies, it’s a safer platform for traditional investors. That said, I still recommend performing due diligence and making sure that the platform’s offerings align with your trading goals.
