This is awesome news. I love Japan.
If Bitcoin ever does become a real preferred currency, it's definitely starting in Japan (and perhaps South Korea) long before anywhere else.
Yes, Japan is amazing country when it comes to new things and also those kind of positive news are supporting crypto currency market. We may also start seeing other companies to follow even in other countries, probably in Europe.
Have to admit that the concept of this company is still very advanced. Bitcoin is very popular at present, and surely some employees will definitely support this decision. Of course, the public also can not figure out the future development of Bitcoin. Whether this policy can be implemented for a long time is still unknown.
