## About

Founded in 2016 and based in Tokyo, Japan, Souco Co. Ltd. d.b.a Souco specializes in innovative inventory solutions, offering a comprehensive luggage storage and warehouse sharing service to help businesses efficiently manage their logistical challenges. Souco provides inventory management solutions through its extensive network of storage locations. The company has completed 4 deals, with its latest being a Series C funding extension round on 26th May , raising an undisclosed amount from  Sumisho Venture Partners. The current valuation stands at JPY 3,094.218 million, reflecting its growth and market presence under the leadership of CEO Kunehito Nakahara. Souco specializes in a luggage storage and warehouse sharing service that addresses various logistical challenges faced by businesses across different industries. The core offering is a vast network of over 2,500 storage locations across Japan, facilitating efficient storage solutions for items such as cardboard boxes, pallets, and cage carts. This service aims to simplify the warehouse selection process for businesses that may be unfamiliar with inquiries or comparisons between warehouses, thus allowing them to secure appropriate storage quickly and easily. Clients include businesses in manufacturing, retail, and e-commerce, all of which seek temporary or long-term storage solutions for inventory management during peak seasons, logistical overflow, or while transitioning to new facilities.The revenue model for Souco is structured around a pay-per-use system, wherein clients are charged based on the volume of goods stored and the duration of storage. Pricing plans are clearly defined, with charges assessed on a daily basis—10 yen per cardboard box and 100 yen per pallet or cage cart, with additional fees for handling and transport services. This transactional framework allows businesses to utilize Souco's facilities for as little or as much time as necessary, enhancing flexibility in managing storage needs. Clients typically engage in business-to-business transactions, with the process encompassing initial consultation on storage requirements, followed by a contract detailing the specific terms and storage solutions tailored to the client's needs. The transparent pricing structure and rapid deployment of services are key elements that contribute to the operational efficiency and customer satisfaction that Souco delivers. In May 2026, souco raised an undisclosed amount in series C funding from Sumisho Venture Partners. This investment will enable Souco to expand its offerings and market presence. The company is focused on enhancing its service capabilities and exploring opportunities for geographic expansion beyond Japan, although specific new markets have not yet been disclosed. The Company will use the May 2026 funding to expand its logistics network, strengthen partnerships, and develop next-generation infrastructure solutions.
