JCB is Japan's dominant credit card network and the card Japanese consumers carry internationally. With 140 million cardholders across 24 countries and acceptance at 34 million merchants worldwide, it sits alongside Visa and Mastercard as a network with genuine global reach — built out from a single market rather than vice versa.

The Japan-specific context matters: 59.5% of all Japanese ecommerce payments are made by credit card, and JCB is the local network of choice. For merchants targeting Japanese consumers at home or abroad — travel, luxury, electronics, hospitality — not accepting JCB means declining a meaningful share of that spend at checkout.

Compared to UnionPay and WeChat Pay, JCB skews toward higher average transaction values, which partly justifies the 3.75% rate. One-click payment support helps with repeat purchase conversion for merchants with returning Japanese customers.

Acceptance covers Europe, Asia Pacific, the Middle East, and North America. Settlement lands in 5 days across a broad currency set including JPY, USD, EUR, GBP, AUD, HKD, and SGD. Partial refunds, multiple partial captures, and recurring payments are all supported.
