JCB: the Japanese card system worth knowing about in 2026

JCB is Japan's native credit card network, founded in 1961 and accepted at virtually every Japanese merchant. JCB-issued cards from Japanese banks are particularly useful at small merchants where Visa/Mastercard sometimes fail; foreign tourists with Discover (JCB partner) or some American Express cards effectively use the JCB network.

TL;DR

• JCB: Japan's native card network, founded 1961.
• Foreign access: Discover (US) cards work via JCB partnership at ~30 million merchants.
• Some Amex cards also work on JCB infrastructure.
• Most useful for: small Japanese merchants where Visa/Mastercard sometimes fail.

What's the relationship between JCB and other networks?

• JCB and Discover: partnership for cross-acceptance
• JCB and Amex: some terminal-level support overlap
• JCB and UnionPay: separate networks, both accepted at major merchants

What this means for tourists

• US travelers with Discover get JCB-network access via partnership
• Most American tourists with Visa/Mastercard cards don't have direct JCB access (it's a separate network)
• For JCB-issued Japanese cards (resident-only), they work globally too
