Can I use OKX in Japan?

I'm just wondering, is it possible to use OKX in Japan? I've been hearing a lot about this cryptocurrency exchange platform and its features, but I'm not sure if it's accessible in my country. I'm quite interested in exploring the opportunities it offers for digital asset trading and investment, but I don't want to get into any legal troubles. Could you please clarify if OKX is available and legal to use in Japan? If so, what are the specific requirements or procedures I need to follow to start using it? Thank you for your help!
