MA System

What MA System does

MA System (株式会社 エム・エー・システム) is a privately held Japanese prototype and small-lot electronic manufacturing services company founded in 1993 and headquartered in Bunkyo-ku, Tokyo. The company provides end-to-end one-stop services covering electronic circuit design, component procurement, PCB fabrication, SMT mounting, precision machining, assembly/wiring, and inspection, executed through a documented 9-step workflow from specification hearing through shipment. MA System targets industrial product developers, electronics engineers, and startups needing prototypes, crowdfunding samples, PR models, or low-volume production runs, including single-unit orders, with typical lead times ranging from a few weeks for urgent projects to roughly one month for standard engagements of 350 components and 1,030 pins.

The company's technology stack is conventional rather than proprietary: it leverages a published network of 100+ component manufacturer partnerships (including Murata, TDK, Panasonic, Rohm, Kyocera, Samsung, Toshiba, and Renesas) for procurement, and an external metalworking partner factory network (協力会社) for specialized processes such as blade and cutting-tool machining. It maintains inventory across more than 10 component brands and handles inventory for customers. There are no AI/ML capabilities, software products, APIs, or proprietary algorithms documented. Differentiators center on project management integration rather than technology depth: a single point of contact across the full value chain, flexible cost-versus-delivery trade-offs, and short-lead-time execution supported by distributed partner capacity.

MA System operates a project-based revenue model with custom quote-based pricing and no published tiers or subscription offerings. Its go-to-motion is enterprise field sales combined with inside sales, driven by a content-rich corporate website (ma-sys.co.jp) that serves as the primary marketing channel through service descriptions, case studies, blog content, and dedicated inquiry/quote request forms. The named customer base is heavily concentrated among Sony Group entities (Sony Corporation, Sony Group, Sony Semiconductor Solutions, Sony Network Communications, Sony Technology Thailand) along with approximately 15 other Japanese electronics manufacturers and distributors. The company is family-controlled by the Saito family, with stated capital of ¥10,000,000 and a headcount of 1-10 employees, and operates exclusively within Japan.

Products and services

• Prototype and Sample Manufacturing Service (試作品制作・サンプル作成サービス) One-stop custom prototype and sample manufacturing service covering circuit board design, component procurement, PCB manufacturing, assembly, inspection, and rework/modification. Supports small-lot production including single-unit orders, crowdfunding prototypes, PR/sample models, and lightweight designs, intended for enterprise customers and innovators developing new electronic products.
• Circuit Board Design and Assembly Service (基板設計・実装サービス) Circuit board (PCB) design and assembly service supporting short lead times. Handles designs of up to 350 components and 1030 pins, including daughter boards, with services covering design through implementation and offering expedited turnaround options for customers needing rapid prototyping.
• Electronic Component Selection and Procurement Support (電子部品選定・調達支援) Electronic component selection and procurement support service that assists customers in choosing appropriate resistors, capacitors, and other components based on circuit parameters, tolerances, and specifications, reducing customer workload in component sourcing.
• Blade and Tool Machining Service (刃物加工対応) Blade and cutting-tool machining service fulfilled through MA System's network of metalworking partner factories, enabling the company to handle machinery manufacturing requests involving durable blade processing that falls outside its core electronics manufacturing capability.
• Parts Inventory Management Service (部品在庫管理) Parts inventory management service with stocked components from multiple manufacturers including Shindengen, NIDEC, COSEL, Panasonic, Nisshinbo Micro Devices, Sanken Electric, Renesas, Mitsubishi Electric, onsemi, Toshiba, Isahaya Electronics, and Fuji Electric, supporting faster project turnaround.

Partnerships

Two partnerships are on record, tiered core and supporting.

• Multiple electronics component manufacturers and distributorscoreOthersMA System maintains a broad network of electronics component manufacturer partners covering major Japanese and international brands. The company publishes a comprehensive 'Makers List' on its website with over 100+ manufacturers including Murata, TDK, Panasonic, Rohm, Kyocera, Samsung, Toshiba, Renesas, Onsemi, Cosel, Nidec, Fuji Electric, Sanken Electric, Nisshinbo Micro Devices, Isahaya Electronics, and many others. These partners enable the company to source components reliably and at competitive cost.
• Metalworking and machining partner factories (協力会社)supportingOthersMA System leverages a network of metalworking partner companies to fulfill specialized machining requests that fall outside its core electronics manufacturing capabilities. An example from case studies shows a blade/cutting tool machining request that was fulfilled through a metalworking partner with relevant machining experience. The network is also used for handling high-volume orders by distributing production across multiple partner factories.
