MIO

What MIO does

MIO Corporation (株式会社エム・アイ・オー) is a privately-held Japanese micro-SME founded on January 26, 1999, headquartered in Ome City, Tokyo, with 1-10 employees and registered capital of JPY 10,000,000. The company operates two distinct divisions: a WEB Solutions Division and an Environmental Division, both targeted at the Japanese domestic market.

The WEB Solutions Division delivers custom web system development using PHP, JAVA, CGI, and Ajax (with MySQL), website construction and management (including WordPress and proprietary CMS), Microsoft Access and Excel-based business application development for SMEs, and IT/OT security solutions including Check Point, Fortinet, and PIOLINK UTM appliance resale plus operational technology security services for manufacturing facilities. Environmental products include proprietary oil adsorption materials (Smiley/Puffin oil mats and fences, AC Light M road adsorbent), asphalt repair compounds (YK Ascon series), the Kumorazu non-powered anti-fog mirror, leak detection tapes, and plant vitality agents, with three registered patents and government type-approval on the Puffin mat.

Revenue is generated through three streams: project-based web and business application development (priced from JPY 200,000-2,000,000 per project), recurring monthly maintenance/subscription contracts on existing systems, and environmental product sales through dealer channels led by Taniguchi Shokai (since 2003), Nihon Comsys (since 2004), and Toshiba (since 2004). The customer base is exclusively Japanese SMEs and government entities, with no public revenue disclosure, no external funding, and no signs of headcount expansion in recent years.
