As one of the world's leading economies with countless cutting edge technologies, Japan has maintained its high-profile status for many decades. Even in this World Cup, Japan has defeated Germany and Spain, striving to the next level of competition. It seems that Japan does not need to prove to be a great nation to the world. However, in the crypto industry, we barely heard anything great from Japan, no leading blockchain ecosystem or any cryptocurrency exchange alike. Why ? Please correct me if I am wrong.
