Liquitous そして Eight-Japan Engineering are jointly developing a generative AI-powered agent designed to support Japanese local governments in preparing regional public transportation plans. The companies presented a prototype of the tool for the first time at Construction Technology Exhibition 2026 Kanto, held on October 20–21.
The AI agent wants to help city officials handle the tasks that come with creating and updating regional transportation plans. City governments usually have a lot to do when dealing with lots of papers looking at data and talking to people who live there and other groups involved.
Liquitous, the company that makes the citizen participation tool called Liqlid is working with Eight-Japan Engineering, a company that gives advice on building things to solve these problems using AI to help with planning and getting people involved.
The partnership started after the two companies made a deal in July 2024 to help people take part and find agreement, in city growth and neighborhood planning.
AI Supports Data Analysis and Plan Development
The proposed AI agent is designed to assist officials throughout the regional transportation planning process through interactive conversations with AI.
One of its functions is to streamline data organization, analysis and document preparation. The system can help review. Analyze existing plans, previous planning documents, statistical information and feedback, on local needs.
Based on these inputs it supports the development of proposed objectives, policy measures and key performance indicators (KPIs). It can also help organize discussion points and prepare briefing materials and draft plans.
The tool is also designed to connect with Liqlid, Liquitous’ online citizen participation platform. This integration will enable local governments to incorporate feedback from residents and relevant businesses into the planning process, supporting more participatory and practical transportation plans.

AI-generated outputs will still require review.
Municipal officials must verify sources and cited passages before making final decisions or approving planning documents.
The companies also clarified that the system remains a prototype, under development and its specifications and functions may change.
Collaboration Builds on Existing Partnership
The project expands the companies’ existing cooperation into the regional transportation sector.
Eight-Japan Engineering will contribute its technical expertise and practical experience in developing, evaluating, and improving regional public transportation plans. Liquitous will lead the development and implementation of the AI agent, drawing on its experience with Liqlid and citizen engagement initiatives.
Liquitous has supported projects involving local governments, including Osaka Prefecture, Shizuoka Prefecture, and Nagoya City, as well as urban development initiatives such as Kashiwa-no-ha Smart City. The company has also worked with government agencies and municipalities in Indonesia.
Next Steps Toward Municipal Deployment
The companies plan to expand the tool’s capabilities through demonstration projects and other trials with local governments, with the aim of moving toward practical implementation.
They are currently giving stakeholders a chance to see prototype demonstrations and talk about possible uses.
By bringing generative AI, citizen participation and transportation-planning knowledge the initiative aims to cut down on the heavy administrative tasks in regional mobility planning. It also supports more inclusive choices, in decision-making.
