Japan already is. I would rather look for updates on how many merchants and stores accept cryptocurrencies in Japan today (it was supposed to be 260k by this summer). And I am more than sure they have created bitcoin and Satoshi (whoever he is) is really Japanese. It's sad they have strict immigration rules, otherwise I'd be already there

Looking good for a very rich country known for its advance technology. I am also planning to visit Japan sometime late this year and hoping for more shops accepting bitcoin and altcoins.
