I think I only see Japan as the first country to really embrace bitcoin. Therefore companies in Japan will also have to accept bitcoin as mode of payment. Example is JAL. There will be big companies from Japan that will follow suit as well. Probably in the next months we well see another big companies from Japan will come out and accepts bitcoin as payment.
Another country that will also embrace bitcoin is Australia starting July 1. Japan is a highly industrialized country which means technology is very advance. Soon Japan will see the potential of other altcoins especially that bitcoin is also facing some trials.
