Mizunara Inc. to Exhibit at Startup JAPAN EXPO 2026 — Supporting 'AI Adaptation of Operations' via Contract-Based Hands-On Solutions and Proprietary Products

Mizunara Inc. (Headquarters: Tsukishima, Chuo-ku, Tokyo; Representative Director: Yuma Kinoshita) will exhibit at the 'Startup JAPAN EXPO 2026', held at Makuhari Messe on Wednesday, April 15, and Thursday, April 16, 2026.

As a university-launched venture recognized by AIIT, Mizunara Inc. supports the AI adaptation of business operations through contract-based, hands-on solutions and proprietary products. During the exhibition, we will introduce OffiStill, Wordless, AI agent PoC development, AI development infrastructure construction, Web system development, and technical support plans to address challenges related to AI utilization in complex Office documents and business processes.

Background of Exhibiting at Startup JAPAN EXPO 2026 While considerations for AI adoption are progressing, there are many challenges on the front lines, such as 'not knowing where to start,' 'stalling at the PoC stage,' and 'original documents or workflows being unorganized.'

In particular, critical documents like contracts, regulations, plans, specifications, and manuals require heavy revisions, span across multiple departments, and entail accountability, making this an area that is difficult to resolve merely by introducing simple tools.

Mizunara Inc. has been providing support from the perspectives of both research knowledge and implementation capabilities, aiming to adapt these complex operations to the AI era. Building upon the document management technology cultivated in the Tokyo Metropolitan Regional Disaster Prevention Plan Database, our strength lies in translating university-originated knowledge into mechanisms utilized on the front lines.
