While countries like China restricted the exchange of Bitcoin, Japan is embracing it. Before China banned bitcoin, it controlled 10%-13% bitcoin exchange.
Last September Japan financial service FSA announced they are legalizing 11 crypto-currencies. Bitcoin was one of them. Now Japan controls more than 60% bitcoin trading which is double of USA. Another main reason for Bitcoin going mainstream in Japan is a large number of vendor and physical shops accepting Bitcoin as their primary payment gateway.
In Japan, bitcoin isn't limited to few crypto enthusiast. People ranging from Housewife to High teachers all are using Bitcoin. Even though most of them using it as an investment, high bitcoin price indicate their investment is paying off.
