Awesome.

Japan has some of the highest average broadband speeds in the world.

Nodes operated in japan could offer an advantage in terms of speeding up the average speed of btc transactions without centralizing networks.

Japan and china tend to be opposed to each other. There are a lot of hard feelings between the two countries after world war II.

It is possible japan could take steps to nullify some of the more unethical practices by chinese involved in crypto.

By the end of 2016, there were around 4200 Bitcoin-accepting merchants and storefronts in Japan, near quadrupling the total from 2015. Now, with the current progress in Bitcoin regulation made by Japanese authorities, the number of merchants accepting Bitcoin is expected to quintuple to 20000 this year. Indeed, good times for Bitcoin adoption are coming.

And imagine all the people that will come to watch Olympics? No more bothering about currency exchanging, you go to another country and you pay with bitcoins in any restaurant, you can buy something else, what a relief will bitcoin be for people that plan to go there and have bitcoins.
I hope we will see some statistics after Olympics about this topic, how many people will spend some bitcoins in this shops, this will be a test for bitcoin.

Firstly people need to be aware of that japan is introducing bitcoins as their currency .well it need to make much progess as the confirmation takes a lot more time , as their speed is not so fast .maybe their will be a option to pay for bitcoins but very people will use it .

Yes, this will be a test for Bitcoins. And the tourist doesn't need to stand in front of currency exchange shops to exchange their currency. But I have doubt that is this real news or fake. If it is real then the local currency exchange they will get big loss in this business.

I think this is good news for the bitcoin community especially in Japan. 

This is really a good news that a particular country already accepted or already implemented for bitcoin to be part of their currency which is great and we can really prove out that its not possible for a country to accept bitcoin completely.I wish i had lots of bitcoins and go to japan to spend them without the need of exchanging to local fiat.

Yes, this news makes me very happy because many of my friends told me to leave bitcoin otherwise you will lose your money. Now I can share this news with my friends, Japan is one of biggest currency, which has positive side on bitcoin acceptance.

It's good news and bad news. Bitcoion been around for years and the price of Bitcoin is really high compared to the price that it began with. If Japan gets more involved with virtual currencies then the guys with paper cash will soon find that they have less money then most people in the Country.
Virtual Currencies are what Japan is aiming for. Bitcoin has the technology to influence the payments made with virtual currency and Japan wants more guys getting into it.

That's a great news, but I doubt its credibility, give us a way to verify it. I do not want to believe and those that are not real. If Japan accepts bitcoin as a payment method, this means bitcoin is getting more acceptance, and it will grow even further. It is the premise for bitcoin to stand firm in the market, and it never gets overtaken by other altcoins. Japan is a very modern country, bitcoin is acceptable, meaning bitcoin is a good investment, so we should support bitcoin.
