Is Coinbase allowed in Japan?

Could you please clarify for me whether Coinbase is permitted to operate in Japan? I've been hearing a lot about cryptocurrencies and their popularity in various countries, but I'm not entirely sure about the regulatory framework in Japan. Could you tell me if Coinbase, as a major cryptocurrency exchange platform, is legally allowed to provide its services in the country? If so, are there any specific regulations or licenses that it needs to comply with? Thank you for your assistance in clearing up this matter for me.
