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 it's not exactly surprising that there is going to be a noticeable increase for JPN exchanges since they also opened up 10 or something additional exchanges over the past few weeks. I have heard from a few people I know that follow business and so in Japan that Bitcoin is becoming something that is mentioned ever-so-occasionally as opposed to the "never" is used to be, but I dunno if that's just because of some bias for what mediums of information they use.
