Summary

Mercari, Inc. of Japan launched a new standalone app, Mercari Japan, in the United States on June 17, 2026. This cross-border shopping platform allows U.S. customers to easily discover and purchase items from Japan's Mercari and Mercari Shops marketplaces. The new app replaces the existing "Mercari x Japan" feature within the U.S. marketplace, aiming for a more seamless international shopping experience. This expansion is driven by surging U.S. demand for authentic Japanese products, particularly collectibles, anime, and fashion, with the cross-border e-commerce market between Japan and the U.S. projected to reach JPY 1.6 trillion in 2024, an 8.0% increase. Mercari Japan's cross-border GMV has grown over 15-fold in three years, exceeding JPY 90 billion annually. The app offers direct access to over 4 billion listings, centralized shipping management, lower costs by avoiding proxy services, and shipping protection, along with AI-powered real-time translation and USD payment support. Future plans include authentication services and auction features.

Key takeaway

For e-commerce product managers considering international expansion, Mercari Japan's strategy highlights the value of a dedicated cross-border app. You should evaluate if a standalone platform, rather than an integrated feature, better addresses specific international customer needs like language, currency, and logistics. Prioritize features such as centralized shipping, buyer protection, and AI-powered translation to reduce friction and capitalize on growing global demand for niche products, as Mercari Japan did for Japanese collectibles.
