the first japan bill containing virtual currencies is expected to come on april which recognizes bitcoin as a method of payment.Although,it doesnot define bitcoin as a legal currency,it is still considered as a remarkable progress for bitcoin in japan.Hope, most of tourists who would go to japan to see 2020 olympics would be able to pay in bitcoins.
THis is going to be a huge step in the right direction for bitcoin in my opinion.
not only does it mean that the government of japan and also government around the world are acknowledging that bitcoin should be a legal currency, they are also saying that bitcoin is functional and can be used.
