LOGIC:The 'Sumida-to-Global' platform, acting as a 'Provenance and Logistics' layer, aims for an 18% commission on the global export value of each Edo-Kiri piece. For an item retailing at a mid-range ¥45,000 internationally, the platform would earn ¥8,100 per unit. Fixed Operational Costs (Monthly, based on current to next few years' Tokyo prices): - **Consolidation Hub Rent (Sumida-ku):** A functional 70-100 sqm space for logistics, quality checks, and inventory holding near Kinshicho or Oshiage could easily range ¥400,000 - ¥700,000, representing a significant fixed drain due to Tokyo's dense urban real estate. - **Specialized Staff (2-3 FTEs):** A Logistics Lead, an Artisan Relations Manager, and a Digital Certification Specialist are critical. Average fully-loaded salary for these roles in Tokyo (including social insurance) will be ¥450,000 - ¥650,000 per person per month. Total estimated: ¥1,350,000 - ¥1,950,000. - **Platform & API Maintenance:** Cloud hosting, Japan Post/Customs API subscriptions, cybersecurity, and ongoing development support will incur ¥200,000 - ¥400,000 monthly. Variable Costs (Per Shipment): - High-quality export packaging, last-mile collection from individual workshops, specific customs declaration fees, and insurance are estimated at ¥1,500 - ¥3,000 per item. Breakeven Analysis: To cover just the lower bound of fixed costs (¥400,000 rent + ¥1,350,000 staff + ¥200,000 platform = ¥1,950,000) and variable costs (assuming ¥2,000/item), the platform needs to process approximately 300-350 Edo-Kiri items per month (¥1,950,000 / (¥8,100 commission - ¥2,000 variable) = ~320 items). This volume demands rapid and consistent scaling across the initially fragmented 200 artisans, a high bar for a novel operational model.
