株式会社エイト

What 株式会社エイト does

株式会社エイト (Eight Co., Ltd.) is a privately held Japanese manufacturer and service provider headquartered in Ueda City, Nagano Prefecture. Founded in 1977 with ¥48 million in registered capital and 26 employees as of September 2025, the company operates three divisions: MDS (Molding & Mold Die System), FAS (Factory Automation System), and OCS (Office Coffee Service). MDS produces high-precision plastic molds and provides injection molding services for automotive, electronics, and consumer-goods manufacturers. FAS designs and builds custom special-purpose machines, automatic assembly equipment, and inspection machines aimed at production automation and labor savings. OCS provides corporate offices with professional coffee machine rentals, beans, and related consumables under a partnership with Daiohs Corporation.

The company monetizes through three revenue streams. MDS and FAS are project-based hardware sales built on custom engineering work sold directly to manufacturing clients, with quotations handled by phone (0268-38-6411). OCS is a recurring-revenue subscription model combining equipment rental with consumable product sales, supported by a dedicated inquiry line (0120-38-6652) and Daiohs' nationwide service network. Go-to-market is exclusively direct sales with a regional Nagano Prefecture footprint; the website functions as a top-of-funnel information portal rather than a transactional channel.

Operationally, Eight functions as a small, diversified industrial and service workshop with a stable, long-tenured customer base rather than a high-growth venture. There is no public disclosure of revenue, no institutional funding, and no AI/ML capability layer. The competitive positioning rests on integrated mold-to-parts capability, customizable automation engineering, and the recurring coffee-service annuity, all delivered through personal direct-sales relationships in a single Japanese prefecture.
