Patrick McKenzie (patio11) reads his 2021 essay "Payments in Japan," tracing how Japanese consumers navigate a landscape with dozens of competing payment methods at once: credit cards, electronic money, QR-code super apps, convenience-store cash vouchers, and bank transfers. Along the way he covers the JFTC's campaign to force credit card networks to disclose interchange rates, how Rakuten and 7-Eleven each bought a bank to solve a payments problem blocking their core business, why PayPay's subsidized 2018 launch let it run away with the QR code market, and why konbini payments remain popular despite a user experience frozen in the late 1990s.
