It's still a tiny portion of total commerce but an absolutely massive jump from previous bitcoin usage.
i.e., regulated it in any way at all; specifically, they said exchanges could trade BTC and ETH.
> Peach Airlines has started taking bitcoin,
no, they ran press releases saying they may well by the end of this year probably.
> huge chains of convenience stores like FamilyMart have been accepting payments in bitcoin, etc.
no, one of their payment processors added a bitcoin option; there's so far no evidence of non-negligible usage.
You're inadvertently parroting speculative bitcoin hype here. The general rule with all bitcoin (and blockchain) media coverage is that there's always much less to it than there appears.
I was in Japan two weeks ago and saw for myself. I was actually surprised about payments being taken in bitcoin when I heard a customer at a FamilyMart talking about it and double checked with the clerks just to make sure I wasn't misunderstanding.
I may have misunderstood the timing with Peach's support, since I wanted to book in NTD (the currency of my bank account) anyway. That said, exactly none of my comment comes from speculative media coverage. It's literally all from first-hand experience interacting with companies as a customer.
