What CORE TECH Japan does

CORE TECH Japan (株式会社コアテック) is a private Japanese IT solutions company headquartered in Sumitomo Realty Aobadai Tower, Shibuya, Tokyo, founded in 2009. The firm operates across nine business segments — Web Integration, Web Marketing, Digital Advertising, Cross-Platform Development, Creative Services, OEM Business, E-sports (including the College E-Project), Global Business, and Back Office support — positioning itself as a one-stop digital-services provider for business clients. Core technical capabilities span upstream website and business-system engineering through SEO consulting, digital-advertising operations (under Google Partner certification), multi-platform development, and creative production, with no proprietary software product, API, or platform disclosed in the available data.

The business model is professional services-led and direct-to-B2B: clients engage through the corporate website contact channel, services are delivered as customized projects on a quote-based pricing structure, and there is no public pricing, ARR, or unit-economics disclosure. Revenue mechanics are therefore inferred to be project-based retainers and one-off engagements. Headcount is reported as 51–100 in the firmographic record (with a separate source noting 100–200 from profile aggregates), and the firm maintains a dedicated recruitment site and new-graduate hiring funnel. The firm holds Japanese workplace certifications including ten consecutive years of 健康経営優良法人 (Health Management Excellence), えるぼし (Eruboshi women's participation), and くるみん (Kurumin childcare support), and it markets a Global Business line with documented activity in Taiwan in addition to its primary Japan market. No funding rounds, M&A activity, parent-company relationship, or leadership changes are disclosed.

• Transcosmos: Large Japanese BPO and digital services company offering website construction, digital marketing, and contact center services; overlaps with CORE TECH but at much greater scale and breadth.
• BIPROGY: Major Japanese IT services firm (formerly UNISYS Japan) providing system integration and software services; competes for the same type of business-system development projects CORE TECH targets.
