Statistics shows that the trading volume in dollars and yen higher than ever, but some believe that these figures should be taken in excess. For example, when China dominated the bitcoin market, this is due to the fact that the trading platform is allowed to trade without fees, which dramatically increased the volume of sales in RMB. Because Chinese exchanges added to the Commission, the trade volume of BTC / CNY in China fell. One of the advantages of a Japanese bitcoin trading is the fact that Japanese stocks do not charge commissions for transactions. It's a little alarming skeptics, since statistics JPY / BTC can be inflated for this reason.
Well I thought that Japan was a lot bigger of a player in the global exchange game since they used to be the home country of Mt.Gox (iirc) and they had those politicians talking about how they would start regulating Bitcoin. I know China always loved to be one of the biggest portions of the pie and they wouldn't have it any other way, but it's good to see Japan catching up since they apparently weren't in the same place I thought they were.
Good to see more competitors to China's control.
