Digital City

What Digital City does

Digital City Inc. (デジタルシティ株式会社) is a Tokyo-headquartered, privately-held Japanese IT solutions company founded in November 2013 by Representative Director 大島予章 (Oshima Yosho). The firm operates across five business lines: DX consulting, contracted software development and SES (contracted development), HR solutions (staffing and recruitment), creative and communication design, and business production services. The company additionally provides IT equipment leasing through its dedicated leasing business and operates the 'siranui' proprietary tool for programmatic advertising operations.

The company's strategic center of gravity in 2024–2025 has shifted decisively toward generative AI. Its Generative AI Training (生成AI研修) offering delivers 12+ hour structured curricula covering ChatGPT, Gemini, Copilot, Dify, GAS, LINE, RAG, and Stable Diffusion at a published price of 400,000 JPY per trainee, and has accumulated over 10,000 LinkedIn-based training participants. Applied AI work has expanded beyond training into PoC deployments, including a phone voice evaluation AI (2024) and AI agent development with food-heritage brand Akafuku (2025). Customer segments are split across local government (Tsukuba City, Omura City, Ise City), enterprise (JR Kyushu Group, listed Japanese majors including Hakuhodo, Dentsu, Ajinomoto, Yonex, Pokemon, ANA Trading), and education (Okayama Nishioudai High School). The company is organized around an affiliated ecosystem of capital and business partnerships — TENHO, PARKING, UNKNOWN, Tobu Top Tours, KANNAGARA, and subsidiary Gov Sync — plus a regional subsidiary in Okinawa.

The go-to-market is sales-led and event-driven: direct enterprise and government field sales supplemented by conference speaking (Keio AI Consortium, Tokyo Digicon X, Nikkei symposiums, CESA) and a sustained media presence (TBS, Nikkei, Benesse). Operations span 110 employees including contractors across Tokyo HQ (relocated March 2025 to Akasaka), Okinawa, and affiliated Nagoya and Shibuya offices. The company holds ISO 27001, ISO 9001, and P-Mark certifications, plus staffing dispatch, employment placement, and secondhand goods dealer licenses — a regulatory footprint consistent with government and enterprise procurement eligibility.

Core offering

Digital City (デジタルシティ株式会社) provides digital transformation (DX) consulting, generative AI training programs, HR/staffing solutions, creative production services, and IT equipment leasing. The company primarily serves enterprises, local governments, and educational institutions in Japan, with a focus on enabling organizations to adopt and operationalize generative AI tools. It also operates proprietary technology platforms to support AI-driven workflows.

Product overview

Digital City operates as a multi-service IT solutions firm rather than a single unified product platform. Its core offerings span five business segments: DX Consulting Services (digital transformation strategy), HR Solutions Services (talent acquisition, development, and management), Creative Business (design and communication), and Business Production Services (growth and operational support). The company also provides Generative AI Training (生成AI研修) as a structured service — an offering distinct from its consulting operations — covering ChatGPT, Gemini, Copilot, Dify, GAS+AI, LINE+AI, RAG, and Stable Diffusion courses. Digital City also developed a proprietary operational support tool called siranui (しらぬい) for programmatic advertising. Through its TENHO sub-brand, it delivers municipal DX and generative AI training programs, and has partnered with Akafuku on AI agent development. The company additionally operates an IT equipment leasing business covering hardware such as servers, networking gear, and multifunction devices.
