The cashless share climbed from 21% in 2017 to 42.8% in 2024 — METI's 40%-by-2025 target hit a year early. Mobile QR codes (PayPay above all) have absorbed the bulk of incremental growth; cards — particularly credit — still carry the value. JCB retains a meaningful domestic share; Zengin is a 50-year-old rail being incrementally modernised, with Wise becoming the first non-bank to join via direct API in late 2025.
Tab 03
Rails & infrastructure
The instant rail, the RTGS spine, the card switch, the direct-debit scheme, and the country's CBDC stance. Each rail is reported with operator, launch year, and 2024 flow so the relative scale across rails is readable at a glance.
CBDC status is deliberately granular: live, pilot, preparation, live stalled, and sceptical, no pilot are different things.
BOJ's pilot programme runs through 2026 with no commitment to issuance. Phase 3 (from April 2025) tests offline functionality, holding limits, and integration with commercial-bank distribution. The stated policy stance is 'if a decision to issue is made', reflecting political and privacy debate in the Diet and industry. Tokenised-deposit infrastructure (MUFG Progmat, Mizuho J-Coin) is running in parallel.
Instant payments
Zengin System (with More Time extension for 24/7)
The instant leg typically carries the vast majority of retail consumer flow in modern payment systems — and sits in direct tension with card networks and wallets for the same transactions.

RTGS
Real-time gross settlement
The RTGS spine clears high-value interbank flow — including the settlement of the instant-rail cycles and card-network net positions. Transaction count is modest; cleared value is enormous.
