SBI is one of the biggest banks in Japan and they are heavily invested in cryptocurrencies and companies that have to do with cryptocurrencies. In January 2018 they will be launching SBI Virtual Currencies in Japan and SBI MAX in Hong Kong, both are exchanges where you will also be able to buy directly with JPY/USD/EUR. We have signed up for SBI Virtual Currencies with the pre-registration but unfortunately it’s not open to the general public yet. Once one or either of the sites open for registration again we will be giving updates and will guide you through the sign up process. You can have a look at their website here but for now it’s in Japanese.
