Zigzag Inc. operates a cross-border e-commerce platform connecting domestic Japanese EC sites with overseas customers in 228 countries and regions through two integrated services: 'WorldShopping,' a purchase proxy and fulfillment service for overseas customers, and 'WorldShoppingBIZ,' an easy-to-implement cross-border EC enablement service for domestic Japanese online retailers. The platform removes language, logistics, and payment barriers by allowing EC site operators to go live internationally within as little as one day by simply adding a single JavaScript tag, with no system modifications required. The company handles multilingual customer support, international shipping, and diverse payment methods (including Alipay, WeChat Pay, PayPal, and overseas Amazon Pay), enabling domestic EC operators to serve global customers without changing their existing workflows.
