Tajima

What Tajima does

Tajima Co., Ltd. (株式会社タジマ) is a Tokyo-headquartered Japanese software vendor specializing in business-management solutions for the automotive aftermarket. Founded in 2005 and operating as a subsidiary of the BroadLeaf Group, the company serves individual proprietors and SMB automotive maintenance workshops (整備工場), body-repair shops (鈑金工場), and inspection stations (指定整備工場), with an installed base of 10,600+ customer companies across Japan.

The company's product portfolio is split between cloud-based SaaS and on-premise software. Cloud offerings include Maintenance.c and Repair.c — browser-accessible platforms for customer/vehicle management, slip issuance, and document creation in maintenance and body-repair workflows — as well as 電帳.DX (electronic bookkeeping compliance under the 2022 revised law), スーパー検査員 (inspection and maintenance record automation), Priceprint.c (used-car total-payment price-board printing), and BL.Homepageプレミアム / BL Navi (CMS and member information services). The on-premise line centers on the 一新多助smart series (smart2 and the high-end smart+2), a factory-management system featuring Smart Multi-Window and cycle-management functions, with integrations such as KTC TRASAS Bluetooth measurement tools and Google Maps.

Tajima monetizes through SaaS subscriptions with automatic version updates, ongoing support contracts (delivered via dedicated phone lines and a 22-branch nationwide support network), and ancillary LED workshop-lighting hardware sales. Go-to-market is primarily direct/inside sales with consultation-led demos (phone and TV phone), supported by an online reservation system. The company holds Privacy Mark (JIS Q 15001) certification and operates exclusively within Japan.
