Why is Binance not working in Japan?

I've been wondering, why isn't Binance operational in Japan? It's such a popular cryptocurrency exchange platform globally, so it's surprising to find it unavailable in such a technologically advanced country. Could it be due to regulatory issues? Or maybe there's some specific legal hurdle preventing its entry into the Japanese market? I'd really like to understand the reasons behind this. Could you shed some light on this matter for me?
