What ISC does

ISC Co., Ltd. (株式会社アイ・エス・シー) is a Tokyo-headquartered private Japanese information-services company founded in October 1984 that operates four business lines: (1) Web Solutions & Operations — DX consulting, hosting, system planning/design/development, and AWS implementation for government and enterprise clients; (2) Website Creation Services — comprehensive site production from planning through maintenance, multilingual builds, and internal SEO, marketed under the ISCW sub-brand (iscw.jp); (3) Staffing Services — dispatch of system engineers and administrative personnel under General Worker Dispatching (since 2004) and Fee-based Employment Placement (since 2007) licenses, primarily to government agencies, public-interest corporations, and select private enterprises; and (4) Scientific Information Search Services — exclusive Japan sales agent for G-Search Co., Ltd.'s JDreamIII scientific technology information search system and Scientific Technology Literature Abstracts, sold to universities, research centers, and private companies.

The company's technical footprint spans web systems development, DX promotion, AWS cloud infrastructure, hosting, database management, and network security, with website production roots going back to 1996. It holds Privacy Mark (2005), ISO 27001 (2010), and ISO 9001 (2017) certifications that signal eligibility for sensitive public-sector workloads. The go-to-market is primarily enterprise field sales — direct engagement with Japanese national R&D agencies (JST, AMED, JAXA, RIKEN), museums (Miraikan since 2001), universities (University of Tokyo), and selected private enterprises (TOHO, Nikon, NTT PC Communications) — supplemented by the ISCW web-solutions brand for mid-market and institutional DX buyers and the JDreamIII portal for scientific-information customers.

Headcount stood at 72 as of April 2025, registered capital is ¥10 million, and the firm is 100% privately held by four shareholders (TOHO, I&E Corporation — also the building landlord at its Ikebukuro headquarters — Nikagyu Information, and Dick Alpha). The 10th President, Yumoto Sadanaga, took office in May 2025, and the company marked its 40th anniversary in 2024. Revenue is not publicly disclosed, but the mix of project-based web creation, recurring hosting/staffing contracts, and agency commissions is consistent with a small-cap Japanese IT services and staff-augmentation firm anchored in the Tokyo metropolitan area with secondary Kansai exposure.
