Building a full-scale EC site usually requires several million yen and extensive custom development. Through our optimized Shopify-based framework, we deliver a fully operational, commercial-grade EC site for only ¥1,000,000, enabling manufacturers to launch quickly during the year-end and New Year period. As a production company specializing in multilingual and cross-border websites, we understand the complexities of global EC operations. Our team supports multi-currency transactions, region-specific tax settings (VAT/GST), global shipping workflows, compliance considerations, and scalable content localization. This makes our solution ideal for manufacturers targeting international markets or managing overseas distributors. A key advantage for the manufacturing sector is Shopify’s enhanced capability to support large-volume product catalogs. With B2B pricing rules, tiered quantity pricing, unlimited SKU management, and seamless API integration with external ERP/WMS systems, Shopify can now accommodate catalogs with thousands to tens of thousands of parts. This allows manufacturers to build platforms for spare parts, consumables, service components, or agent-only ordering systems without costly custom development. For complex industrial products, we also configure related components mapping, compatibility tables, model-to-parts associations, and structured navigation to reduce search friction and improve ordering accuracy. When necessary, we integrate external databases to support BOM-like hierarchical structures. Beyond development, we apply our proprietary ACTSITE methodology, a strategy-first framework refined over 20 years. Rather than “just building a site,” we design the entire conversion ecosystem: ・User journey design ・Information architecture for industrial buyers ・Search and filtering optimized for part catalogs ・Cross-border UX and multilingual clarity ・Lead acquisition flow and operational alignment with your sales team This ensures your EC site not only “exists,” but functions as a revenue-generating component of your business. This campaign is available for a limited time only. We invite you to take advantage of this opportunity to build a high-performance EC platform at a fraction of the typical cost. Initial consultation and requirement definition are offered free of charge.

● This is a leak testing device for small electronic components that does not use fluorinated inert liquids (PFAS-free). ● There is no longer a need for unstable visual confirmation through liquid immersion testing. It adopts a quantitative testing method that allows for stable pressure leak testing. ● It is a tabletop leak testing device specifically for gross leaks, with accuracy equal to or greater than that of liquid immersion testing. ● The detectable range is approximately 1×10⁻² Pa·m³/s to 1×10⁻⁶ Pa·m³/s (varies depending on the target product). ● It is suitable for sealed structures ranging from a few millimeters to a maximum of 80 × 70 mm.

Hotron's vehicle detection sensors allow you to search for products that meet your needs in three categories: "Purpose of Use," "Location of Use," and "Product List." The sensors detect the passage of vehicles, alerting you with rotating lights or switching the display of parking availability. They manage vehicle presence, full parking, and exit warnings in parking lots, contributing to safe driving and smooth operational management within the parking area. They are used in various settings, from coin-operated parking to large-scale parking lots.
