Document House

What Document House does

Document House Co., Ltd. is a privately held Japanese documentation services and compliance technology company headquartered in Hachioji, Tokyo, founded in 1987 and incorporated in 1989 with ¥40 million in registered capital. The company operates a one-stop model spanning manual production, technical and multilingual translation (50+ languages), DTP and technical illustration, multimedia production (video manuals, e-learning, mobile apps, websites), and regulatory compliance consulting. Its primary vertical focus is medical device manufacturers (IFU production, MDR compliance) and industrial machinery manufacturers (ISO/SEMI standards documentation), supported by a 30+ year track record and an enterprise client base of 500+ companies including Sony, Canon, Fujifilm, Komatsu, Fanuc, Olympus, Terumo, NTT, KDDI, IBM, Cisco, Amazon, AIG, and Siemens.

The company's core technology platform consists of two patented cloud-based SaaS products launched in 2023: i-CRAS2, an ISO31000-compliant enterprise risk assessment system using Control Self-Assessment methodology with 17 industry templates; and ManualDock2, an IEC82079-1-based manual quality evaluation system. These are augmented by i-CRAS_super (customized risk assessment) and supported by a translation memory database accumulated across 10,000+ technical documents. The business model is hybrid — professional services billed per project (manual production, translation, multimedia, consulting) combined with annual subscription SaaS (i-CRAS2, ManualDock2) priced at ¥94K–¥166K entry tier.

Document House generates leads primarily through digital marketing (corporate website, English-language site for international prospects), SEMICON Japan trade show participation (2018, 2019), and PR distribution. Distribution is direct-to-enterprise via consultation forms, phone (0120-668-030), and web meetings. The company maintains one wholly-owned subsidiary, Document Safety Co., Ltd. (established July 1997), specializing in regulatory compliance services, and has historically formed alliances with AIU Insurance (1995), Japan Standards Association (1997), AIG (2007), Resona Research Institute (2010), and Abeam Consulting (2010). The company is led by founder-president Toshiaki Honma and operates without external private equity or venture capital backing.
