Souco

Souco is a Tokyo-based B2B warehouse sharing marketplace that connects businesses needing flexible storage with warehouse and fulfillment center providers across Japan. Founded in 2016, the platform enables companies — from manufacturers and retailers to food and beverage firms — to book on-demand warehousing space starting at ¥30,000 per month without long-term commitments. With a network of over 3,000 partner warehouses spanning all 47 prefectures of Japan, Souco handles a wide range of cargo types including pallets, cardboard boxes, refrigerated and frozen goods, large machinery, construction materials, and apparel. The platform supports use cases such as temporary storage during office relocations, exhibition equipment handling, import cargo staging, and FBA fulfillment preparation for Amazon Japan. The service is targeted exclusively at legal entities, including sole proprietors, schools, medical institutions, and professional firms.
