What TAJIMA Japan does

TAJIMA Japan (株式会社タジマ) is a Tokyo-headquartered, privately-held software vendor that develops and sells cloud-based business-management systems exclusively for the Japanese automotive aftermarket. Founded in 1975 and operating as a subsidiary of BroadLeaf Group, the company serves automotive maintenance shops, auto body repair shops, used-car dealers, and adjacent SMB customers through a portfolio that includes Maintenance.c, Repair.c, the 一新多助smart2 / 一新多助smart+2 factory-management series, 電帳.DX (electronic record retention compliance), スーパー検査員 (vehicle inspection support), Priceprint.c (used-car price board printing), and the BL.Homepageプレミアム CMS.

The technical core is browser-delivered SaaS with integrated customer/vehicle databases, digital document handling, and Bluetooth integration with KTC TRASAS measurement devices for automated tire and brake data capture. The company monetizes primarily through annual subscription fees and maintenance/support contracts, with a secondary hardware line (LED lighting for workshops). Pricing is contact-based and not publicly disclosed; customer acquisition is sales-led, supported by industry seminars, case studies, and an email newsletter.

Distribution is direct, leveraging 22 nationwide branches that enable same-day on-site support — a structural advantage over horizontal SaaS competitors. The installed base exceeds 10,600 companies, almost entirely Japanese SMBs. The CEO is Osaki Shoji (大﨑 章司). Recent activity (2025) centers on a 一新多助 Smart series upgrade tied to the Automobile Recycling System overhaul, a December 2025 partnership with Aputy Co., Ltd., and a Hokuriku branch relocation.

Direct peers

• BroadLeaf Co., Ltd. Parent group of TAJIMA Japan and itself a provider of automotive aftermarket software and SaaS in Japan. Closely comparable because it operates the same automotive-vertical software model and shares distribution and customer base, making it the most directly relevant peer despite being the parent.
• ACT Co., Ltd. Japanese vendor of dealer management and automotive business systems for car dealerships and related shops. Comparable to TAJIMA as a domestic vertical SaaS provider targeting Japanese automotive business customers with workflow and document solutions.
• PBS Systems: Provider of dealership management systems (DMS) and CRM for automotive dealers in North America. Comparable to TAJIMA as a vertical SaaS player focused on automotive shop and dealer workflow software with a similar target customer profile.

Broad incumbents

• Reynolds and Reynolds: Large US-based provider of automotive retail management software and services to dealers. Comparable as an established incumbent in automotive vertical SaaS, but operating primarily in North America at a much larger scale than TAJIMA.
• CDK Global: Global provider of automotive dealership software, CRM, and data solutions. Comparable as a broad incumbent offering workflow SaaS to automotive retail and service businesses, but at materially larger scale and broader geographic footprint than TAJIMA.
• Cox Automotive (Dealertrack): Cox Automotive's Dealertrack unit provides dealer management and automotive technology solutions. Comparable as a broad incumbent serving similar end markets (dealers, automotive retail), but at much larger scale and across many geographies.
• Anritsu Corporation: Japanese provider of test, measurement, and inspection equipment with automotive applications. Comparable to TAJIMA as a Japanese technology vendor serving automotive inspection workflows, though Anritsu operates as a much larger global measurement-equipment incumbent.

Others

• KTC (Kyoto Tool): Japanese manufacturer of professional automotive tools including the TRASAS measurement device line that integrates with TAJIMA's software. Not a direct competitor, but the closest hardware ecosystem partner serving the same automotive shop customer base.

Regional players

• Pinewood Technologies Group: UK-based automotive retail SaaS provider serving dealer groups in Europe. Comparable as a vertical SaaS player for automotive dealerships, but regional in scope and serving a different geography than TAJIMA.
