FreshCatch is a direct-trade fresh-fish marketplace connecting fishers, fish shops, and buyers directly. Around 500 sellers deliver the day's catch straight to tables nationwide.
Direct-trade marketplace, seller operations, freshness-preserving logistics, trustworthy buying experience — the story of launching a new platform, built in-house from scratch on EC-CUBE in 9 months, satisfying all four axes a direct-trade fish EC needs at once.
Uminoichi Co., Ltd. is a direct-trade fresh-fish platform operator connecting fishers and fish shops nationwide directly with consumers. Its 'from the shore to the table' direct-sales model, bypassing markets and wholesalers, creates benefits in both freshness and price.
Traditional fresh-fish distribution runs through many layers: fishers earn thin margins, and by the time the fish reaches buyers its freshness is often gone. We launched our own marketplace from scratch on EC-CUBE, supporting the whole flow end to end — from a fisher listing to the buyer purchase, order, and shipment.
None of these were about tech choices — they were business requirements tied directly to freshness, fisher margins, and buying experience. A from-scratch build demanded a design that makes them all hold at once.
We built four domains — a two-sided marketplace, seller operations, freshness-preserving logistics, and a trustworthy buying experience — through large-scale customization with EC-CUBE at the core. Building on an OSS foundation let us skip rebuilding payments and cart from scratch and focus on the features direct-trade fish sales truly need.

This foundation is not a technical metric — it continuously produces business outcomes like freshness, fisher margins, and buyer satisfaction.
