SAZO

SAZO is a Japan-based agentic AI cross-border commerce platform founded in October 2023 that eliminates barriers to international online shopping by automating language translation, shipping fee prediction, customs duty calculation, and last-mile delivery coordination. Initially focused on enabling Japanese consumers to purchase Korean products with a single click, SAZO has since expanded to serve Korea-to-Japan and Japan-to-global flows, partnering with major platforms including Mercari, Rakuten Ichiba, and Rakuma. The company uses AI agents to predict shipping and customs costs with claimed 95% accuracy and handles the entire post-order logistics chain, positioning itself as a partner rather than just a tool. SAZO raised a Pre-Series A in September 2025 and closed a Series A with backing from NAVER D2SF, growing GMV over 1,290% in ten months.
