Yes, I'm also amazed how Japanese really embrace bitcoin in their daily lives there. I think they are doing a great job as leaders in bitcoin market, and it just a matter of time before another nation would adopt bitcoin because Japan is setting a good example. And Japan has greatly impacted the price lately, pushing it to $1600-$1700.
Japan right now is the main reason for the noticeable surge of the Bitcoin price and we have just started here. Japan is poised to open up at least 10 Bitcoin exchanges maybe within this year.
And with this development, am sure that other countries would took notice and soon can also be adopting Bitcoin as a currency along with their nationally recognized fiat money.
