Considering Japan have a great reputations in terms of business, this kind of news will give more chances for cryptocurrency to get even more better this year. And I hope there will be more companies from Japan will follow or adopt what Rakuten did so that people in crypto community will have a confidence again to invest.
If this will be fully executed, then for sure this will make a huge impact in the market. Hoping that this will help the market recover, especially in bitcoin price. If a lot of merchants will do the same thing like what the Rakuten did, cryptos popularity will drastically increase.
