The U.S. has the world's most developed and widely relied upon credit reporting infrastructure, by a substantial margin. The history of FICO doesn't quite fit into the margins of this comment but I'd love to do an issue on it someday. Credit scores per se are less a thing in Japan but there are cross-issuer I-can't-believe-its-not-bureaus which have information sharing agreements, the dominant purpose of them being identifying fraudulent actors and account takeovers rather than credit risk (nearly zero in Japan, historically).
