What HIMACS does

HIMACS (株式会社ハイマックス, HIMACS Ltd.) is a Yokohama-headquartered Japanese system integrator founded on May 21, 1976, and listed on the Tokyo Stock Exchange Standard Market (ticker 4299). The company delivers high-value-added solutions across the full system lifecycle — from planning and design through development to post-deployment maintenance — primarily for enterprise clients in financial services (banking, life insurance, securities, credit networks), public sector, aviation, and distribution. Its portfolio includes a life-insurance new-contract system capable of processing millions of policies annually with paperless image workflow, server and desktop virtualization platforms, an AWS cloud development and migration practice, multi-channel connection systems for banks, and a tablet-based flight-plan system used by ANA pilots.

Underlying technology is conventional enterprise IT rather than proprietary AI: core stacks include Java/.NET frameworks deployed on on-premises infrastructure or AWS (Amazon ECS serverless, CodePipeline/CodeCommit, Snowball, DMS for large-scale database migration). HIMACS holds Privacy Mark, ISO 27001, and ISO 9001 certifications, supporting eligibility for regulated-industry contracts, and maintains 1,738 information-processing technology certification holders across its 967-person consolidated workforce.

HIMACS generates revenue through project-based professional services engagements with enterprise and financial-institution clients, primarily via direct sales and through the NTT Data Group ecosystem (NTT Data, NTT Data i, NTT Data Advanced Technology, NTT Data China, and NTT Data Financial Technology are all named major clients/partners). Consolidated revenue stood at ¥18.2 billion for FY March 2026, with a consolidated dividend payout target of approximately 40%. Strategic partners include AWS, IBM Japan, Fujitsu, and NRI; the company operates a single-country (Japan) footprint concentrated in the Kanto region.
