Good news to hear. Japan will be soon followed by China. Thus about (1/5)th of the world population will be involved and know about bitcoin. The last two weeks the bitcoin price was around 3500-4200, this will definitely help and decide the bitcoin price to continue to appreciate. Very good news, I am waiting for when Japan will be also involved in farming bitcoin for all the world.
It is indeed a good news, kudos to Japan! China was mistaken to have allowed itself stand in the way of a force, whose time have arrived. With the latest development Japanese exchanges are going to attract and mop up all those volumes China took for granted and that would be boost overall global demand for Bitcoin.
