One of the main card processor (Cardnet) was down for about 7h, and it's the 3rd time in recent years (happened twice in 2017 and 2019 per the article). This is a big deal, while still being limited (there's other card payment processors) and less impacting than if it happened in more card centric countries. Many people solely rely on cash and prepaid electronic wallets, which are more widely accepted than credit card (one can easily find a small shop that only accepts cash and PayPay or Suica, with no intent to ever accept credit card)
