> Since the government approved btc as a currency,

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.
