Daisan

What Daisan does

Daisan (ダイサン・株式会社) is a Japanese custom industrial equipment manufacturer founded in 1953 as Tanaka Iron Works in Nagoya, Aichi, and rebranded under its current name in 1999. The company designs and builds special-purpose machines used to mass-produce "key devices" — the components and sub-assemblies its customers embed into finished products. Its equipment base is engineered for serial production rather than piece-volume manufacturing, with each tool sized to a specific customer process and integrated into the customer's production line.

The company's portfolio spans six end-markets: consumer electronics, automotive, building/office/housing equipment, industrial/FA, medical, and environmental/energy applications. Customers are major manufacturers who outsource the design and fabrication of bespoke production tooling. The operating model is project-based: each engagement is a one-off custom build, with revenue recognized per equipment delivery rather than on recurring contracts. Approximately 80% of deliveries are made to overseas customers, and the company runs subsidiaries in Vietnam (Daisan Dot Vietnam) and Korea (Bestec) to support localized delivery and service to those accounts.

Daisan is a privately held company with ~100 employees (as of October 2021), headquartered in Komaki, Aichi Prefecture. Registered capital was increased to approximately ¥100M in 2018, supporting a multi-year program of factory expansion and overseas subsidiary buildup. President Tomokatsu Tanaka (田中 知克) has led the company since the 1999 renaming. Revenue is not publicly disclosed.

Revenue model

1. Custom Special-Purpose Equipment Design, Manufacturing and Sale: Daisan generates revenue through the in-house planning, design, production, and sale of bespoke industrial manufacturing equipment. Each project is a custom one-of-a-kind machine, meaning revenue is project-based and tied to individual customer orders. The company also provides after-sales maintenance and remodeling services, creating a service revenue stream.
2. Overseas Manufacturing Operations: Through its Vietnam subsidiary (Daisan Dot Vietnam), the company conducts parts manufacturing operations, supplementing the Japanese manufacturing base.
