Tax Refund Startup Ocean Secures JPY 500m Series A Ahead of Japan’s Overhaul on Duty-Free Shopping Rules
Ocean Inc., a Tokyo-based FinTech startup operating the refund-model duty-free platform "Ocean Tax Refund," has finalized its Series A funding round, raising approximately ¥500 million (US$3.3 million).
The company reached a second close for the round following new investments from KURONEKO Innovation Fund No. 2—a corporate venture capital arm jointly managed by Yamato Holdings and Global Brain Corporation—and Shizuoka Capital, the venture investment subsidiary of Shizuoka Financial Group. This follows the initial tranche announced in September 2026.
The capital injection comes at a critical juncture for Japan’s retail sector. Effective November 2026, Japan will officially phase out its traditional point-of-sale tax exemption in favor of a post-purchase tax refund mechanism. The regulatory overhaul requires duty-free retailers nationwide to simultaneously overhaul cash register software, refund workflows, and multi-language customer support.
Ocean plans to allocate the fresh capital toward expanding its support infrastructure for merchant onboarding and scaling software solutions. Beyond capital support, Ocean intends to leverage Yamato’s nationwide logistics network and Shizuoka Financial Group's regional business relationships to assist regional retailers outside major metropolitan hubs in adapting to the regulatory shift.
Founded in May 2024, Ocean has rapidly built strategic distribution channels across Japan’s payments and financial services landscape, recently entering into partnerships with Recruit and Kyoto Financial Group.
