Company profile
researched Aug 2026株式会社souco operates souco, a warehouse-sharing (倉庫シェアリング) service for corporate customers in Japan. Rather than letting customers search listings themselves, souco staff interview the customer about cargo type and storage period, select a suitable warehouse from its partner network, confirm availability, and then present the location, access details and available sections. Contracts can begin as soon as the day after signing, and souco arranges a driver to collect the goods and transport them to the warehouse, where storage starts on arrival.
The service is structured around standardized storage units and plans, including cardboard-carton, pallet and roll-cage (kago daisha) plans, plus refrigerated/frozen carton and pallet options and constant-temperature (定温) carton and pallet options. Space-based options range from a small "choi-oki" plan of roughly 4-30 tsubo for smaller or short-term volumes to larger spaces of about 50-300 tsubo that can include working areas. Non-standard load formats such as banjū trays, styrofoam boxes, flexible container bags and cage carts are also accepted. Beyond storage, souco handles related logistics tasks such as transport arrangements, in-warehouse work, and Amazon FBA delivery support including pre-shipment storage, inspection, labeling and dispatch.
Advertised entry pricing is from JPY 30,000 per month, with the small-scale plan advertised from JPY 50,000 per month. The site also publishes educational articles on warehouse selection and inventory management topics such as apparel inventory placement, seasonal factory-shutdown logistics planning, and storing heavy or long-length goods.
Business model
souco acts as an intermediary between companies needing storage and warehouse operators with spare capacity, matching demand to space in its partner network and layering on transport, in-warehouse work and fulfillment services. The site includes a separate entry point for warehouse owners wishing to offer space, indicating a two-sided marketplace structure [0].
Customers pay monthly storage fees, advertised from JPY 30,000 per month, with plans priced by unit type (carton, pallet, roll cage, refrigerated/frozen, constant temperature) or by floor area; the small-scale plan is advertised from JPY 50,000 per month. Additional services such as transport, inspection, labeling and shipping are offered alongside storage [0].
Traction
The website states the network has passed 3,000 warehouse locations covering all 47 prefectures, and publishes customer case studies including 株式会社ネットレックス・フィールドサービス (storage plus work space for outsourced client operations), 株式会社日本ドニン (temporary storage of large precision equipment for trade shows, with in-warehouse work), and 株式会社北陸建材社 (temporary storage of construction materials after a sudden work stoppage) [0].

Market position
souco positions the service around flexible, as-needed capacity from a large multi-prefecture partner network, standardized small-unit plans (single cartons, pallets, cages) alongside larger area-based spaces, temperature-controlled options, a consultant-led warehouse selection process instead of self-service search, and start of use as early as the day after contract completion [0].
Go-to-market
Inbound, consultation-led sales through the website: prospects download a service brochure or request a free consultation, after which souco staff conduct a needs interview and propose a plan.

Common use cases are storing store or office fixtures and furniture, temporary storage during relocation or renovation, overflow store inventory and promotional materials, trade-show fixtures and equipment, post-import staging of imported cargo, and Amazon FBA preparation [0].
