What CIOS Technology does

CIOS Technology Co., Ltd. (シオステクノロジー株式会社) is a Tokyo-headquartered private Japanese IT services company founded in July 2001 (formerly China Portal Co., Ltd., renamed in June 2015) with 135 employees and 25 consecutive years of profitability. The company operates two revenue streams: (1) IT staffing and labor dispatch services, holding General Worker Dispatch Business Permit 派13-308131 and billing clients at a disclosed rate of 33,582 JPY per 8-hour day with a 36.6% gross margin; and (2) fixed-price / time-and-materials bespoke system development and infrastructure construction covering the full lifecycle from requirements definition through testing, deployment, and ongoing operations/maintenance. Projects are concentrated in Tokyo and Kanagawa with no relocation required for employees.

The underlying technology stack is conventional enterprise IT: Java, .NET, Python, C#, C++, JavaScript/TypeScript on Windows and Linux; databases including Oracle, SQL Server, DB2, PostgreSQL, and symfoware; infrastructure including VMware, RHEL, AWS, server/network/storage provisioning; and legacy-modernization work such as COBOL-to-Java migration. The company is not a product vendor — it delivers bespoke projects with no packaged software offerings.

CIOS serves Japanese enterprise and public-sector clients across four verticals: financial services (life and P&C insurance, banking, investment), telecommunications (communications carriers), public sector (local government municipalities for welfare and financial accounting systems), and manufacturing/logistics (automotive manufacturers, logistics firms, power companies). Distribution is exclusively direct sales with no resellers or indirect channels. Notable customers include JFEコムサービス, NTTデータCCS, 富士通Japan, 日立社会情報サービス, クレスコ, アイエックス・ナレッジ, and インテック. The company maintains Privacy Mark certification (7th renewal, January 2026) and has been featured in the Tokyo Metropolitan Government's SME workplace charm promotion (December 2025).

Expansion highlights5 records

Broad incumbents

• Meitec Corporation: Japan's leading 'designer-dispatch' (設計開発派遣) firm placing high-end engineers at client sites for R&D and development work. Comparable to CIOS in IT engineering dispatch economics, but focused upstream on mechanical/electrical engineering.
• BIPROGY (formerly Nihon Unisys): Major Japanese IT services firm with deep financial services and public-sector footprint. Comparable to CIOS because it serves the same regulated verticals (insurance, banking, government), but operates at significantly larger scale and with broader service breadth.
• TechnoPro Holdings: Japan's largest IT engineer dispatch and outsourcing firm with a separate custom-development business. Comparable to CIOS in the labor dispatch (派遣) revenue model and IT engineering staffing value proposition, but at significantly larger scale.
• Pasona Group: Major Japanese staffing and HR services group with IT and engineering dispatch operations. Comparable to CIOS by labor dispatch license and IT staffing economics, though Pasona's portfolio spans many non-IT segments.
• NTT Data Group: Largest Japanese IT services firm serving financial services, public sector, telecom, and global enterprises. Comparable to CIOS in financial-services + public-sector system development, but at massive scale.
• TIS Inc. Mid-large Japanese IT services group covering finance, telecom, and public sector with full-stack development, maintenance, and IT outsourcing. Comparable to CIOS by vertical focus and engineering-services delivery, but at materially larger scale.

Direct peers

• Nihon Systemware (NSW): Mid-size Japanese system integrator delivering custom software and embedded/IoT solutions for industrial, public, and enterprise clients. Comparable to CIOS in custom systems development and full-lifecycle project delivery.
• JBCC Holdings: Japanese mid-tier IT services and solutions provider serving enterprise clients across financial services, manufacturing, and distribution. Comparable to CIOS in B2B enterprise system development and multi-vertical service delivery.
• Future Corporation: Japanese IT services firm serving finance, manufacturing, and distribution sectors with both system development and infrastructure services. Closely comparable to CIOS in size band, vertical mix, and project-based delivery model.
• Nihon Computer Consultant (NJC): Mid-size Japanese IT services firm with a strong focus on financial services and insurance core systems. Highly comparable to CIOS by vertical mix (insurance, banking) and by custom development + IT staffing business model.
