Overview

Japan payment infrastructure includes central-bank settlement assets, BOJ-NET, interbank transfer clearing, small-value transfer infrastructure, account-direct payment, debit payment, card settlement, wallet settlement, and private-sector clearing arrangements. This page separates customer-facing payment products from the systems and rules used for clearing and settlement.

This page belongs to payments domain and links to account-to-account payment route, merchant bank-account direct acquiring, funds transfer vs prepaid boundary, bank API route, bank API incident and fraud-control map, Japan code-payment competitive map, Japan card acquiring stack, quick deposit four methods, and JapanFG legal / financial licenses.

BOJ Settlement Layer

The Bank of Japan provides settlement assets and operates BOJ-NET. BOJ materials describe settlement assets as money or securities that have been transferred, and describe payment and settlement systems as organized arrangements that can include systems, rules, agreements, and sometimes relevant laws and regulations.

Funds transfers between BOJ accounts are used for interbank money market transactions, cash legs of JGB and other securities transactions, and net positions from private-sector clearing systems. BOJ account debits and credits are also used for money-market operations, lending transactions with financial institutions, treasury funds, and JGS issuance / redemption.

Zengin System Route

The Zengin System is the nationwide online interbank domestic funds-transfer system. Zengin-Net materials describe its bank-transfer role and related clearing route. The system covers almost all private banks in Japan.

Zengin clearing materials identify netted positions and BOJ current-account settlement as the interbank settlement layer. Transfers of JPY 100 million or more are routed through BOJ-NET RTGS rather than ordinary netted settlement.

Cotra Route

Cotra is the small-value bank-account transfer route connected to the five-city-bank small-value infrastructure concept and the operator company established in 2021. Public service materials identify personal transfers of JPY 100,000 or less and a service start in October 2022.

Public Cotra materials identify deposit-taking financial institutions and funds-transfer operators as participant categories. The service supports account-number routing and phone / email-style alias flows with sender-side name confirmation. Public source packs record that connected operators’ funds are cleared through Zengin twice intraday for final settlement.

JEPPO, J-Debit, and Bank Pay Route

JEPPO promotes account-linked payment infrastructure. Its public service pages identify J-Debit and Bank Pay as core account-linked payment services.
