AKI-JAPAN

What AKI-JAPAN does

AKI-JAPAN (株式会社アーキ・ジャパン) is a Japan-based, privately held human resources services company specializing exclusively in the construction industry. Founded in February 2007 and headquartered in Tokyo (relocated to the Osaki Twin Building East Hall in Shinagawa in February 2025), the company recruits, trains, and dispatches construction engineers — primarily project managers (施工管理職) and site supervisors — to construction companies and project sites across building, civil engineering, equipment, and plant sectors. The group operates through wholly-owned subsidiaries including Act-Japan (training and education), JAG Field (technical staffing, acquired March 2022), Jinzai News, and JASTY, and sits under holding company Asproad Holdings (formerly J-CEP, renamed November 2025).

The company's core technology and product stack is purpose-built for construction-industry talent: (1) AJ School (AJスクール, established 2014) and the J-CTEC (Japan Construction Technology Education Center) facility provide specialized training for construction management, CAD operation, and certification preparation with VR-enabled experiential learning; (2) ConMa (launched January 2021) is a construction-specialized job portal with what the company describes as the largest number of construction-related job listings in Japan; and (3) the AI Recruitment Concierge (launched February 2024) provides automated 24/7 candidate Q&A on the exabase.ai platform. Notable brand recognition includes a No.1 ranking in six construction HR categories (employee satisfaction, matching satisfaction, review ratings, engineer registrations) in 2018 General Research surveys.

AKI-JAPAN makes money primarily through dispatch/outsourcing fees on placed construction engineers (HR Outsourcing Business, the managed services stream) and through training and certification program revenue (HR Education Business, the professional services stream). GTM combines direct enterprise field sales — career planners visiting construction firms — with event-driven recruiting via job fairs, internship programs, and online self-service via ConMa. The company reported group revenue of 110 billion yen in FY2020, reached 3,445 employees as of October 2025, and secured a strategic capital partnership with UT Group (TSE 2146) in April 2021 to stabilize capital and leverage UT's operational resources.

Expansion highlights5 records

Direct peers

• Willgroup: Japanese staffing company with a meaningful construction and manufacturing engineer dispatch segment alongside other HR services. Comparable in serving Japanese SMEs and contractors with field-based sales and similar billable-headcount-driven economics.
• Open Up Group (formerly CareerLink): Japan-focused construction and manufacturing engineer dispatch and HR services group with significant overlap in construction engineer placement. Operates a similar enterprise field-sales motion to construction firms and competes head-to-head for billable engineers.
• TechnoPro Holdings: Largest Japanese technical staffing and engineering services group, with substantial construction, plant, and mechanical/electrical engineer dispatch. Directly comparable in serving Japanese construction and engineering clients with a similar dispatch-plus-engineering-services model.
• WDB Holdings: Japanese staffing and HR services group with technical and scientific dispatch (including engineer categories). Comparable in field-sales-led dispatch of engineers to Japanese enterprises, though its mix tilts more to scientific/R&D than pure construction.
• UT Group: TSE First Section-listed Japanese staffing company and a direct competitor in construction and manufacturing engineer dispatch. UT Group is also AKI-JAPAN's capital partner, making it a hybrid competitor/investor with the most overlapping customer base, billable engineers, and service lines.
• Trust Growth: Japan-based staffing company with a strong construction engineer dispatch focus and similar nationwide branch structure. Directly comparable in targeting construction companies with skilled-labor shortages and dispatching project managers and site supervisors.
• Human Holdings: Japan-listed HR services group spanning education, dispatch, and placement, including construction and technical staffing. Comparable in offering a vertically integrated train-and-dispatch model, though with broader HR segment exposure than AKI-JAPAN.

Broad incumbents

• Recruit Holdings: Japan's largest HR services conglomerate (Indeed, HRMOS, staffing). While AKI-JAPAN competes with Recruit's staffing businesses for the same construction client base, Recruit is a broad incumbent operating across many verticals and not a construction specialist.

Others

• Jinzai News: Wholly-owned AKI-JAPAN subsidiary offering HR services and recruitment advertising in the Chubu region. While a related entity, it operates an adjacent recruitment-advertising model and is useful for understanding AKI-JAPAN's diversification into broader HR media.
• Leverages: Japanese HR services company with whom AKI-JAPAN has a long-standing partnership (since 2017) on young-talent development. A thematic peer in the Japanese HR solutions space rather than a direct dispatcher, useful as an ecosystem/adjacent comparator.
